When working as a landscape designer, I always advise my clients plants that combine visual appeal with unpretentious care. One of the most beloved plants is garden hibiscus, which is what I use more often than others when designing plots.
The plant is able to transform any landscape, it looks extremely impressive. In the article I will tell about this plant, I will share experiences on how to plant and grow garden hibiscus.
Garden hibiscus - a real decoration of the backyard landscape. In addition to the exceptional external decoration, the plant can also boast of flowers suitable for brewing delicious tea. It is hibiscus flowers that are used as the basis for the famous Karkade.
In addition, the plant is also quite unpretentious: its care and reproduction does not cause difficulties.
At home plants - Hawaiian Islands - it is also called the "flower of love." Hawaiian women adorn their hairstyles with spectacular colors.
It can be different in height: tree species are the most tall. Separate descriptions deserve flowers plants. They have the form of a pronounced funnel, formed from five or more (terry varieties) petals.
The parameters of the funnel can be from 6 to 15 cm, there are also varieties in which flowers in the uncool state reach the diameter of a soccer ball.
Coloring is various: pink, white, blue, lilac, red shades are more common. There are also two-colored, striped, bordering varieties - they are the most decorative.
Garden hibiscus is able to withstand frost down to -20 degrees without shelter. Of course, in most Russian regions, the plant will need to be sheltered for the winter. Shrub blossoms for a long time - from late June to October. Can be as an annual plant, and perennial also known for its evergreen and deciduous varieties.
Plants refers to malvaceae. In nature, there are about 250 species of this flower. The following varieties are cultivated in garden conditions:
- tree hibiscus,
Different types and varieties of garden hibiscus are used in the design of the homestead landscape in different ways. If the variety is short, it is ideal for borders, including mixed ones.
Grassy hibiscus looks spectacular in combination with roses and other beautiful ornamental shrubs.
The same tree species perfectly combines with massive coniferous trees and shrubs, as well as with low-growing flowers. Hibiscus: photo in the garden.
Since the garden hibiscus loves water, the plot on the shore of the reservoir, the pond, is perfect for him. Growing hibiscus in the open field is simple, and miniature plant varieties are suitable for pot cultivation.
Where and when to plant
All types of hibiscus garden will feel great in a well-lit place. The more sun, the better. But at the same time, the place where it will grow should be protected from the wind. When choosing a place, be sure to note that you choose it for a long time. Garden hibiscus refers to floral long-livers. In one place, without renewal, he will live for 20 or even more years. The composition of the soil for grassy species is considered not particularly important, they can grow on loams. There are only two conditions - the soil should not be calcareous, and not swamp. He does not like waterlogging. For Syrian hibiscus, light and fertile soil is preferred. Most often they are planted with roses. What is suitable for a rose is also suitable for a hibiscus tree. Yes, and it looks in the rose garden beautifully and harmoniously.
The most favorable time for planting hibiscus garden - spring. But we must wait for steady heat, and only then plant. For the coming winter, the plant will get strong enough for the winter season to successfully overwinter.
How to plant hibiscus
In principle, for both species of this plant, the planting technique is the same. The only difference is that for a Syrian hibiscus it is necessary to prepare a hole twice the size of the plant's root system.
Pre-pit must be prepared. Hibiscus garden reacts very painfully to waterlogging, therefore, we must take care of creating a good drainage layer. For this purpose, well-beaten brick (red). It will be enough to 15 centimeters layer of bricks. The same layer of sand is poured onto it, and the top is covered with a layer of compost (also 15 cm.). Compost, in turn, is powdered with a fifteen centimeter layer of sand. In this way, we get efficient and nutritious drainage. It is also desirable to ease the ground taken out of the fossa by mixing it with sand and peat (two parts of the land - one part of the sand and four parts of the peat). After such preparation, you can gently place the plant in the ground, fill it with the prepared mixture. The hibiscus root collar should be only slightly covered with earth when planted.
After planting, around the plant make a watering circle, and pour it. When the water is absorbed and the ground settles, add more mixture, aligning with the general surface of the flower bed.
Science knows many species and varieties of this beautiful plant, however, in the open ground in Russia, only a few of them are usually grown:
Further features of these species.
This is the most suitable hibiscus for our climate, as it is quite frost-resistant. His homeland is not Syria, as you might think, but China.
In natural conditions, Syriac hibiscus reaches 5 meters, but with cultural cultivation it is only 3 meters. Usually cultivated as a small tree. The plant is decorated with elongated dissected leaves and large flowers, reaching a diameter of 6-12 cm.
It is of African origin. Reaches 80 cm in height, it differs by its core root system and straight elongated branches. The name comes from the type of foliage - the leaves are divided into three parts.
The flowers are small, reaching only 4 cm in diameter. However, due to their number and external showiness, the shrub looks very picturesque. The color of the petals is yellowish, the core is red. Flowers bloom only in the morning.
Bred artificially by crossing swamp hibiscus, red and holly. Differs in long years of life and very beautiful, bright and large flowers.
Requirements for conditions
We find out in what conditions the hibiscus street will best show its decorative qualities.
Planted plant is necessary in the sunny part of the garden.
At the same time the place should be protected from drafts and gusts of wind.
The composition of soil hibiscus does not impose special requirements, which greatly facilitates the task of the gardener. It is better to grow and develop a shrub in loamy soil, it is undesirable to plant it on a site with lime soil.
It is important that the bed has a good permeable ability, is loose and drained: the plant does not like stagnant moisture. And the most spectacular flowering can be achieved by planting hibiscus in the soil in a neutral or slightly acid reaction. It is also important that the soil be sufficiently nutritious, rich in organic matter.
Garden hibiscus is a tropical flower, so it is not indifferent to warmth. When the winter shelter is removed in the spring, it is necessary to build a film greenhouse above the shrub in order to protect it from returnable frosts. With the onset of sustainable heat, the need for a greenhouse disappears.
In a garden setting, hibiscus can be propagated in two ways:
Next, consider the features of both options.
This method is the longest, but if it is not possible to propagate hibiscus vegetatively, there is no other way out. Seeds need to be stratified before planting to harden the plants.
Seeds are placed in the ground, sprayed with water and cleaned in this form in a refrigerator for stratification. The procedure lasts a month, after which the seeds are planted in the substrate for germination. The substrate should consist of peat and sand.
Capacity cover with foil and placed in heat (+ 25-27 degrees). Regularly you need to lift the film for airing, as well as spray the soil from the spray.
After germination, wait for the formation of several true leaves at sprouting and dive sprouts into separate pots.
Keep in mind that hibiscus will bloom in this case only in the third year.
For this method it is best to choose the spring. The stalk is cut from young shoots 5 cm below the bud-node. After cutting, the lower leaves are removed from the cutting and the cut is treated with a root stimulator.
Rooting occurs in the ground: you need to bury the cutting to the knot. Top sapling cover with plastic and so withstand about a month. During this period, the cutting rooted, after which it can be transplanted to the garden bed. In this case, the hibiscus will start blooming next year.
It is possible to plant on a bed both seedlings of hibiscus grown from seeds and cuttings with roots. Next step by step process.
- Prepare pits for plants at a distance of a meter and a half from each other. The size of the fossa should be twice the volume of the roots of the plant.
- At the bottom of the recesses put a drainage layer of broken brick.
- Put sand on top, then compost, sand again.
- Remove the seedling from the container so as not to damage its vulnerable roots.
- Put the seedling in the hole, fill the roots with soil (earth + peat + sand). The root neck should be located just below ground level.
- Roots the seedling, forming a watering hole around the trunk.
- Water the plant.
How to care
With proper care, the plant can safely live for 15 years, annually at the same time pleasing with its flowering. Let's get acquainted with the basic requirements for the care of garden hibiscus.
The plant requires regular and fairly abundant moisture. However, it is important to avoid flooding the soil and stagnant phenomena in it. See that the soil on the bed with hibiscus was constantly wet, but without puddles.
If there is a drought, water the plant daily, and on cold days, the procedure can be omitted. After watering, it is recommended to loosen the soil to ensure good permeability of the soil.
This procedure requires, mainly, young hibiscus. Usually transplanted in early spring, trying to catch up to the beginning of sap flow.
If we are talking about grassy hibiscus, it should be transplanted especially carefully. The fact is that the roots can not be damaged - such a carelessness can very quickly lead to the death of the plant. So dig out the bush very carefully, trying not to hurt its roots, it is better to retreat to a decent distance.
Since the winters in our country are usually harsh, it is necessary to survive the cold garden hibiscus under shelter. Frost below -20 degrees the plant will not stand.
Before the cold weather, hummer the basal circle with peat, cut off and then cover the bush with sacking or agrofibre. In this form, the plant will be able to safely survive the winter.
Fertilizers for garden hibiscus must necessarily contain phosphorus. And before taking shelter for the winter, feed the plant with potassium - a fertilizer will help you survive the cold more easily.
We met with such a magnificent plant as hibiscus garden. This unique shrub boasts a rare ornamental, combined with unpretentiousness. It will decorate any area, perfectly combining with most garden plants.
Now you know how to plant it and how to care for it - by following the tips from the article, you can avoid many problems when growing hibiscus.

Garden Hibiscus Description
The garden hibiscus plant can be a tree, shrub, or grassy plant. For example, tree hibiscus in a garden is a Syrian rose, which is grown both as a standard tree and as a shrub up to one and a half meters high. A grassy hibiscus is represented by varieties of hybrid hibiscus. Herbaceous forms of plants can be annuals, although perennial hibiscus attracts gardeners much more. Despite the differences in shape, all hibiscus have common features. The leaves of hibiscus more or less notched, petiolate. Hibiscus flowers are large, bright, simple or double, of a wide range of colors - white, yellow, crimson, dark red, lilac, blue, purple and purple. There are varieties with a border around the edge of the petals or with a peephole of a contrasting color. Fruits of hibiscus - five-leaf boxes with seeds. Today, besides garden species, there are about five hundred forms and varieties of hibiscus.
Hibiscus tree. Types and varieties
It belongs to the family Malvaceae. There are about five hundred species of hibiscus tree, but only three are considered the most common:
- Syrian. He especially conquered gardeners with his juicy and variegated colors. Not whimsical. It tolerates frosts. Suitable soil - clay, in which he can live for about a hundred years. Popular varieties are terry - purple and white - pink flowers, as well as simple varieties - dark crimson or violet - blue.
- Hybrid. This species is characterized by large inflorescences. Perennial and thermophilic plant. Among the popular varieties there are: “Albus”, “Violet Elar Double”, “RussianViolet”.
- Chinese. Not whimsical, evergreen. Growing mainly Chinese hibiscus in room conditions, but, if the climate allows, you can grow in gardens.
Attention! If you twist the trunks of several varieties, you can get a nice tricolor tree.
When and how to plant
Garden hibiscus can grow both at home and outdoors in the garden. Despite the fact that special care for its maintenance is not required, it is still necessary to follow certain rules.
Before planting a tree, it is necessary to choose a place for it with suitable favorable conditions. This should be an open area on the sunny side, without hitting drafts.
After the place is chosen, it is necessary to prepare the ground for planting. It must be fertile, with good air permeability and ability to dry quickly. The presence of sufficient humus content will ensure good growth and flowering.
The pit for planting should be two to three times the root system of the plant. At the bottom you need to put a layer of broken brick, then a layer of sand, compost and again sand. The seedling is placed in a pit and powdered with a mixture of topsoil, peat and sand in a ratio of 2: 4: 1.
For good growth requires constant maintenance of moisture, but the main thing is not to pour, otherwise the root system will die. After planting, the seedling is curled and poured over a circle in the formed recess.
Attention! Planting hibiscus is carried out in the spring.
Proper Hibiscus Transplant
As a rule, garden hibiscus planted in the ground does not require frequent replanting. But it happens that it is simply necessary. This is also done in the spring. All rules are followed, as when landing. It is important not to forget to trim the hibiscus. And next year it will be possible to enjoy the beautiful flowering plant.
Hibiscus in central Russia. Wintering
For a long time it has been and nowadays many gardeners have assumed that hibiscus is a purely tropical plant. But there are a large number of varieties that take root well in central Russia and without problems exist in winter conditions in open ground. However, some species can not boast of special frost resistance and they need to be sheltered for the winter.
In order for the plant to enjoy its lush beautiful flowers for a long time, it is important to know and study the characteristics of each of the varieties, and to cover exactly those that really need it. So, Syrian varieties need special warming for the winter. In adult hibiscus, cooling resistance is also increased.
So, what is necessary for the conservation and good wintering plants. It should be remembered that the best time to prepare a flower for wintering is the second half of November, when the temperature begins to fall. Experts do not advise to cover the plant before, as they believe that it should get used to temperature changes and become slightly tempered.
In case of severe frosts, the use of special frames is not recommended for shelter, since the material covered with them does not release air to the outside, this plant will lead to rotting.
To protect from the cold in this case, the best laparic. Он накапливает тепло и обладает в тоже время хорошей пропускной способностью, что не даст растению погибнуть от перегрева.
Attention! Rodents (mice, for example) can wade under shelters used to shelter hibiscus. For the preservation of the bush are placed around the small mousetrap.
Nothing complicated is required and consists of only three steps:
- It is necessary to completely dig a bush out of the ground.
- Rhizome knife cut into pieces.
- Planted on the principle of planting in open ground.
Attention! Seeds planted in the soil need a lower heating.
Permanent pruning is needed only hibiscus garden tree. It should be carried out in early spring or before the onset of winter. There are several types of trimming.
To stimulate flowering. The structure of hibiscus is arranged so that the formation of the bud falls at the very end of the branch. This method of pruning old branches to one third of the stimulates the appearance of young shoots, which will bloom flowers.
For hygiene or thinning
It is used in the event that the growth of branches is too thick, or there are dried old ones. They must be removed. At the same time, the bush is examined for the presence of insects that can harm young shoots with buds.
Damaged branches are cut to a healthy place - the wood on the cut will be colored green. About the presence of an inanimate branch will show a white slice.
Pests and diseases
Such a plant as hibiscus is rarely exposed to any diseases or insect invasions. However, if it is not watered, it will begin to suffer from an insufficient amount of moisture, which will contribute to the attack on it by aphids, spider mites and thrips.
To eliminate such pests, it will be necessary to use the treatment of the plant Aktellik or Fitoverm twice with a ten-day interval.
The most common disease that hibiscus is exposed to is chlorosis. Under its influence, lower shoots and leaf cover turn yellow. Gardeners studied 2 types of this disease:
- Infectious. Viruses, fungi and other microorganisms - the main cause of the appearance of the disease. It is carried by aphids, thrips, spider mites. To prevent and give a normal state, the plant is fed up, if necessary, transplanted and sprayed with water to wash off all the dirt and dust.
- Non-infectious. The main reason is the wrong mode of watering, finding the plant in the shade.
One of the most common pests for hibiscus garden is aphid. As a rule, it attacks young saplings that have not yet had time to get stronger. In this case, to treat the plant, you need a special drug.
Also often the attack of spider mites, which settles under the leaves, and it is difficult to notice it immediately. The presence of yellowed leaves will tell.
- Fall budded buds. This may be due to excessive watering or lack of nutrition.
- The top leaves turn yellow and the bottom fall. Reason: the water used in irrigation is oversaturated with iron.
- Abundant presence of green, but not blooming. Too much nitrogen used in fertilizer.
- Faded foliage. Not enough moisture.
- There is a drying of the roots. Indicates a lower temperature of the soil in which the hibiscus is located. In this case, the plant must be transplanted. Listening to the flower and understanding that he needs, you can save him.
Despite the fact that the plant is thermophilic and feels relatively comfortable at a temperature of eighteen degrees, the temperature regime of 14 - 15 contributes to better flowering. In the summer months it is recommended to take the plant to a balcony or veranda, but to avoid drafts.
Lighting should be maximum, without direct sunlight. If it is not possible to remove the flower from the window, then it should be darkened.
Watering and spraying should be carried out in a timely manner and regularly. Before that, the water should settle and be at room temperature. Under very hot conditions, evaporation of moisture is important to prevent. For this, the ground is covered with expanded clay or moss.
The main condition for leaves is daily spraying. It should not be forgotten that the flowers themselves should not be exposed to moisture.
At home, hibiscus is not so capricious. Even if any mistakes are made, they are easily corrected, and the flower will immediately respond to the changes.
Do not worry much if the leaves begin to turn yellow. This can only remind you that the water used must be carefully filtered in order to reduce its chlorine content.
If you follow all the secrets of caring for hibiscus, everyone can effortlessly grow this tropical flower on their windowsill, and every day admire the magnificence of its bloom and beauty.
Plant hibiscus garden and its varieties
In total, in natural conditions, there are 200 varieties of hibiscus, and through the efforts of breeders, their number increased to 500. All cultural species are divided according to the form of development:
- grassy varieties,
Growing and caring for garden hibiscuses is an exciting experience. In landscape design, all types of plants occupy special niches. Grassy varieties winter well under cover and give beautiful curtains, masking economic facilities.
Planting and care of hibiscus garden - photo - shrubs, allows you to get a hedge and a variety of compositions formation. It is especially easy to work with unpretentious Syrian hibiscus. The shrub became the most common in the mild climate of the middle lane. It is easier to cover for winter conservation.
To grow in an unusual climate hibiscus garden, in the care and reproduction need to adhere to the recommendations of breeders. The main operations are considered:
- choose a planting place
- pour and feed,
- prepare for wintering.
Care includes protecting plantings from pests, diseases and the creation of decorative forms.
On a bright sunny place and without a transplant hibiscus garden can grow up to 20 years. The chosen place should be protected from wind and scorching sunlight. Planting plants from a container or transplanting should be carried out in the spring, when the plant is full of vitality. Saplings planted well-developed plants. Mostly transplanted bushes overwintering in a container in warmth.
Proper rooting hibiscus
The strong root system of a plant consists of a central stem with processes. A hibiscus transplant is not needed if it gets enough nutrition. Therefore, the landing pit is prepared in advance. It is dug out with a reserve, so that the roots have a place for development at first in loose soil. Down stack nutrient composition:
- sod land - 2 parts
- leafy ground - 2 parts,
- ripened humus - 1 part,
- coarse sand - 1 part.
Poured half a bucket of water. On the pillow arrange the roots, without damage, with the expectation that the upper tier will be at the level of the surface. Only light roots work on plants, old ones take nutrients for themselves.
Gently pour and compact the earth, and from above, plant spillage and watering the soil between the roots. In the photo planting and subsequent care of hibiscus tree.
If the plant needs to be transplanted to a new place, then the best time is in spring before flowering. At the same time, the upper roots are removed, and the tree is moved to a new place without destroying the earthy coma. That the plant could feed the upper part, before transplanting do pruning crown.
Important in the cultivation and care of hibiscus garden is regular feeding phosphorus - potash fertilizers. Phosphorus activates flowering, and potassium improves the plant's winter hardiness. Juice with a high content of potassium salts do not like the aphids, the main pest of the plant.
Formation of an ornamental plant
In some areas with cold winters, hibiscus is grown as a tub plant. If three plants with different flowers are grown in one container, then intertwining trunks in the process of growth can produce a multicolor composition with a common trunk, as in the photo of a garden tree hibiscus.
In the spring, with the advent of new stems, old dry twigs are removed. Pruning needed necessarily bloom only young branches. Therefore, remove the extra branches before the sap flow in the spring. Old branches are cut, shoots of the last year are shortened by a quarter. Bushes by systematic pruning can be given the desired shape. There are several types of pruning:
- stimulating, in early spring,
- thinning, removal of dried, weakened shoots,
- autumn, after cessation of flowering,
- for survival, when leaving a minimum of ground mass.
When to plant hibiscus.
Before planting, think carefully about where your hibiscus will grow, because the choice of location determines how long the plant will decorate your garden - with a properly selected area and good care, hibiscus grows in one place to 20 years! Hibiscus seedlings are planted in the spring, when the threat of night frost has passed, so that they can settle down and grow stronger over the summer. Ideal for hibiscus would be a bright and sheltered place with a light fertile, moisture-permeable soil - one in which it is good to plant roses. You can generally arrange hibiscus among roses, they will get along fine.
Caring for hibiscus garden is very simple and not time consuming. As soon as young green shoots appear on the hibiscus, remove old, dried stems from it. Loosen the soil around the hibiscus regularly, remove the weeds and make sure that the hibiscus bush does not thicken much. During the active growing season, from June to September, the hibiscus needs additional feedings with a high content of phosphorus and nitrogen twice a month, and in the fall, when preparing the plant for the winter, potash fertilizers are added to phosphate fertilizers. Unfortunately, the hibiscus flower lives only for a day, but with good care, the plant blooms so abundantly that instead of one flower, another flower immediately opens, so do not forget to remove faded flowers in time.
Hibiscus pruning is carried out for sanitary purposes, as well as to give a tree or shrub a certain shape. Many people prefer to grow hibiscus in the shape of a tree, but for this you will need time and patience. In a young plant that has just been planted, the branches are shortened to the level of two or three buds, without cutting only the well-developed trunk. In subsequent years, at the end of winter, prune side shoots to one or two buds, and the stem - to 5-6 buds. When the stem reaches the required height, form the crown of the strong shoots of the tree, shortening them by several buds. Remove the lower growth and slightly trim the top of the trunk. How to prune hibiscus in order to maintain plant hygiene? Sanitary pruning is carried out in early spring, before the start of sap flow. Old, sick, underdeveloped and growing shoots inside the bush are completely removed, and last year's growth is shortened by a third, which largely stimulates the laying of new flower buds. Remember: the more the hibiscus is cut, the more it will give young shoots, which means that the more it will bloom. The rejuvenating haircut of an aged bush involves the removal of all old, dead branches and shortening the remaining shoots inside the bush by two thirds. It will be better to cut the branches around the main shoot to different heights - this will give the bush a beautiful shape.
If you have a need to transplant hibiscus, do it in early spring, after cutting the shoots to half the length and before flowering begins, in the order as already described. How to care for hibiscus after transplanting? Do not forget to water the plant abundantly, but otherwise treat it as described in the previous sections, and it will bloom in a year. If you transplant a hybrid hibiscus, at the same time with the transplant, you can divide the rhizome of hibiscus.
How to propagate hibiscus.
As you can see, even planting gardeners are able to plant and care for hibiscus. The reproduction of hibiscus and its care after reproduction are just as simple. Hibiscus garden (Syrian) is propagated by layering, grafting, but most often cuttings and seeds. Hybrid hibiscus multiplies by dividing the bush, grafting and green cutting.
Hibiscus from seeds.
Growing hibiscus seeds begin from January to March. Before sowing, hibiscus seeds are soaked for half an hour in a dark pink solution of potassium permanganate, and then for a day in a small amount of a solution of epine, so that the seeds are barely covered with them. After that, the seeds are sown in containers with a mixture of sand with peat, covered with glass and placed in a warm place where the temperature is kept at 25-27 ºC, it would be nice to arrange a container for sowing the bottom heating. It is also necessary to regularly air the seed container, remove condensate and moisten the substrate. When the first leaves of the seedlings develop, they are planted in personalized pots. Make sure that the seedlings do not stretch out: if they lack light, you will have to arrange artificial light shoots. In the open ground hibiscus seedlings are planted in mid-May. Strong specimens can be planted immediately to a permanent place, while weaker ones are planted to grow on the training bed at a distance of about half a meter between specimens. Garden hibiscus, unlike hybrid hibiscus, also reproduces by self-sowing.
Harmful insects and hibiscus diseases.
Hibiscus is rarely affected by insects and diseases, but if during a dry time it suffers from a lack of moisture for a long time, it can be occupied by thrips, aphids, whiteflies and spider mites. To eliminate pests have to resort to a double treatment of plants with insecticides Actellic, Fitoverm, Inta-vir, Karbofos with an interval of a week or ten days.
Of all known diseases, hibiscus in the garden most often affects chlorosis - the lower leaves of hibiscus fall, and new ones grow yellowish. This happens because of the lack of nitrogen and iron in the soil, so iron chelate should be added to the water for irrigation, and in the spring, do not forget to add complex mineral fertilizer containing nitrogen to the soil.
Hibiscus turns yellow.
Hibiscus leaves turn yellow from chlorosis, as well as in the case of a root injury, which the plant could have received during transplantation. If the hibiscus turns yellow due to the roots, then it is necessary to add Zircon or Kornevin to the water for irrigation (see instructions) and for spraying the leaves (three drops per half liter of water). The hibiscus leaves turn yellow and as a result of inadequate watering in a sultry dry summer.
Hibiscus does not bloom.
If you planted hibiscus on a bright spacious plot and look after him, as agrotechnists require, but he nevertheless does not want to bloom, most likely it is a matter of lack of phosphorus and boron. And if the shoots slowed their growth, then the problem is also a lack of nitrogen. Do not forget to make the necessary fertilizers in time for hibiscus, and it will definitely bloom.
Hibiscus leaves fall.
If the leaves of hibiscus fall in the fall, it is a natural process, but if it happens prematurely, then the problem arose either due to improper watering (insufficient or excessive), or the root of the plant is injured. For recommendations on what to do in these cases, see the previous sections.
Hibiscus fall in the garden.
Hybrid perennial hibiscus almost all winter-hardy, they can be grown all over Ukraine, and in Russia only south of Moscow, but on the condition of shelter for the winter. The ground part of the hybrid hibiscus dies off in the fall, so it is cut to almost the surface and burned, the remains of the bush are watered abundantly, and then the spud is high with earth, and the area, in case of too cold or snowless winter, is mulched with sawdust or dry leaves. Next spring, the powerful rhizomes of the hibiscus hybrid will give new shoots, in which beautiful flowers will bloom.
How to winter hibiscus.
How does hibiscus horticultural, or Syrian? In conditions of the middle band, he needs compulsory shelter, especially if you grow terry plant varieties. Some gardeners living in regions with harsh winters, dig up hibiscus, put them in a container or a large pot and keep until spring in the basement or in another cool room, and in spring they are planted in open ground again. If you decide that your hibiscus will winter in the garden, in the second or third decade of November, when the air temperature stays between -5 ºC and -10 ºC, build around the hibiscus a frame on which to stretch lutrasil, spanbond or agrotex. If there are no frosts stronger than 15 ºC in your area, your hibiscus will be reliably protected by such structures. However, the best way to protect hibiscus from frost, and at the same time to avoid them vyperyvaniya under the materials that do not let the air, is shelter hibiscus bushes lapnikom, accumulating snow on themselves and not allowing hibiscus to sweep and overheat. With a spiderweed, the plant is covered in three layers, overlapping branches like a hut, after having bound the hibiscus bush with a rope and put a sack bag on it. Однако часто в такие укрытия забираются грызуны и в тепле поедают кору на гибискусе, обрекая растение на гибель. Для того чтобы мыши или крысы не погубили ваше растение, разложите вокруг гибискуса мышеловки или поставьте под укрытие приманки – отравленную ядом от грызунов пшеницу.
Гибискус сирийский (Hibiscus syriacus),
как ни удивительно, происходит из Китая, а не из Сирии. In nature, plants of this species reach a height of 5-6 meters and are deciduous shrubs with bright green ovate leaves about 10 cm long and single flowers of different colors. In a culture, besides hibiscus with simple flowers, a terry hibiscus is grown, and the shape of a plant can be both bush and standard. Of the popular varieties of greatest interest are:
- – Diana - shrub up to 2 m high with white flowers with a wavy edge of the petals about 12 cm in diameter,
- – Wyelite Ilar Double - very powerful upright growing bush with double or semi-double flowers of violet-blue shade with red spots in the middle,
- – Pink Giant - bush with single pink flowers with a purple spot at the base of the petals,
- – Carneus plenus - shrub with flexible shoots and double pale pink flowers with a purple spot in the middle.
Triple Hibiscus (Hibiscus trionum)
- the species comes from central and northern Africa, although today it is widely grown in all areas of irrigated agriculture. The root of this plant is a stem, straight stem, branched, up to 80 cm high. Leaves are tripartite, petiolate, alternate, with pubescence. The flowers are yellowish, up to 4 cm in diameter, with a dark red middle. A peculiarity of the species is that the flowers open in the morning for only a few hours, and close in the afternoon. The flowering of plants of this species lasts more than a month, because a new hibiscus bud is formed in the bosom of each leaf, and if optimal conditions are created for the trifoliate, new flowers will appear daily.
Hibiscus hybrid (Hibiscus hybrida).
In addition to these two species, growing both in the wild and in culture, hybrid hibiscus and its varieties are grown as garden plants. As already mentioned, this hybrid was bred when crossing three North American species - horned (armed), bright red and marsh hibiscus. Hybrid hibiscus - herbaceous perennials, which are spectacular and very large flowers. Top grades:

Hibiscus - the flower of death
All the superstitions that hibiscus brings misfortune to the owners, that its flowering means the approaching death, in fact, relate to indoor hibiscus, namely, the Chinese rose, or the Chinese hibiscus. About the hibiscus garden, whether it is Syrian or hybrid, no one has yet invented any accepting, so feel free to grow this beautiful and undemanding flower in your garden.
Hibiscus - species and varieties
Starting to write this article, I did not think that the classification of garden hibiscus, their division into species, varieties would cause difficulties. But it turned out to be quite a challenge. I did not find a clear systematization of species and varieties. But I can still share some information..
There are wild and domestic species. There are annuals and perennials. Of them can be distinguished tree, shrub, grassy species.
Wikipedia, by the way, gives its classification of species:
- Hemp or Kenaf (Hibiscus cannabinus) - used by the spinning industry of some tropical countries,
- Chinese, or Chinese rose (Hibiscus rosa-sinensis) - indoor culture
- Rosella, or Sabdarif or Sudanese Rose (Hibiscus sabdariffa) - from the family Malvaceae, distributed in tropical countries, was originally bred in India,
- Syrian (Hibiscus syriacus) - a common perennial species in Russia for cultivation in open ground. Frost-resistant, perennial, bushy,
- Triple or Northern (Hibiscus syriacus) - annual herbaceous plant growing on the mountain slopes, along the rivers and lakes of Asia, India, the Mediterranean, etc.
Separately separately mentioned another species - Marsh or Musk (Hibiscus moscheutos) - a perennial herbaceous plant, a favorite of gardeners in the south of Russia. In winter, the aboveground part dies off.
Let's try to figure out what types of hibiscus exist. Let us take as a basis the classification according to the methods of growth and the forms of development: grassy, shrub, and tree-like.
- Herbaceous - tall shrub with strong erect branches, large leaves, large flowers. The diameter of the flower (depending on the variety) can reach 40 cm. The bush dies annually in the autumn, and in the spring it throws away young shoots again.
- A shrub is a slowly growing deciduous shrub with many branches. Blooms profusely throughout the season. Flowers are medium in size from 5 to 25 cm in diameter. By the way, all shrub species can be formed into one trunk, getting beautiful flowering trees.
- Tree - single-leaf deciduous tree that can grow up to 5-6 meters tall. The whole season is covered with flowers up to 12 cm in diameter.
A common feature of all varieties: the flower lives only a day, but at the same time one faded bud is immediately replaced by a new one that blossoms, so the flowering seems to be permanent.
Now there are new varieties - the flowers can stay fresh for more than one day. But it all depends on the degree of coverage. The more sunny place you have chosen for your pet, the longer the life of one flower. But still, the flowering time is short - from one to 2-3 days.
Landscape designers are very fond of garden hibiscus of all kinds. Urban gardens, parks often adorn shrub species. And in the private courtyard, suburban areas are increasingly possible to meet grassy species.
These are hybrids that were bred by crossing three varieties of North American origin - Norway, pink, red. This is a perennial, which, after the withering of the ground part under the condition of sheltering the root system, can withstand temperatures down to -30ºС.
The rhizome of one specimen is quite powerful, looks like a tuber. The bush blooms from mid-summer to late autumn. At the same time can bloom from ten or more flowers.
Grassy varieties are very popular because of large (up to 30-40 cm in diameter) bright colorful flowers (white, red, pink, burgundy, etc.), sometimes terry. The height of this plant can reach three meters. Such a length of the branch has time to reach in one season.
Among grassy the most popular among gardeners: marsh. Why so called? Because for the first time, the whole thickets of this incredibly beautiful plant were found in the marshes along the Mississippi River, where they are perennial. In our country, they also belong to the perennial, but with the aerial parts of the bush dying off in winter.
Grassy varieties look great on beds with stunted neighbors. For example, in the center of the rose garden, your pet will be a magnificent king. Huge flowers the size of a plate will surprise not only you, but your guests, neighbors, just passersby.
Grassy Hibiscus Varieties
Copper King variety - compact bush. The rounded compact form is achieved by annual shaping not more than 120 cm tall. Dark green, delicate, shaped like maple leaves can change color, which depends on the ambient temperature. Flowers are large up to 30 cm in diameter, the colors of strawberry mousse are white-pink with bright pink stripes. The heart of the flower is crimson-red. Resistant to diseases.
Cranberry Crash variety - grows in a rounded, lush shrub with landscaping from the roots, with a height of 90-120 cm. It has green, purple-veined foliage foliage. Flowers large up to 25 cm in diameter, juicy burgundy color with dark stripes on the petals.
Old Yella is a strong shrub with strong shoots up to 100-120 cm high, with landscaping from the roots. The leaf is green, feathery, maple-like form, with a violet hue in sunny light. The flowers are huge 30 cm in diameter, white or cream in color with a red core. Wavy petals.
Separately, garden yellow grassy hibiscus is discussed in different forums - this species has several varieties, but, according to some growers, they can all be only annuals! Direct text is written: “Do not believe, if they try to sell you a perennial yellow, such a hybrid does not exist, although breeders are trying to achieve this. This species will have to be sown with seeds every year. ”
But, nevertheless, some amateur gardeners claim that they grow yellow perennials. Perhaps you, readers, can bring clarity? If your garden is decorated with this flower, have experience in the care, cultivation, write a comment.
Among the most popular shrubs - Syrian, which has many varieties. Its flowers are smaller in size than those of a grassy species, reaching a diameter of 12 cm. The colors are varied: flowers of violet, white, red shades, varieties with two-tone color are found.
The splendor of some varieties of flowers complements the long pistils with fluffy stamens that attract bees and butterflies.
With proper care, the bush is usually richly covered with flowers, it looks very gentle, although it grows more slowly than grass. On a bright, sheltered from the wind, scorching sun place can grow up to 20 years.
The height of the bush reaches two or three meters, less often four or six, and the width - 1.5 meters.
But acquiring a young copy, do not suffer the question: why hibiscus does not bloom. Syrian shrub blooms only after 3-4 years.
Shrub Hibiscus Varieties
Sort Ardens – perennial deciduous shrub growing up to 2-3 meters tall. Easy to form, like a stem tree. Dense flowering rather large (up to 14 cm) terry lavender flowers or pale pink.
The variety Blue Satin is a perennial spreading deciduous shrub. Height can be up to 4-6 meters. Often form a shtamba to make a bush compact tree, or a single trunk, removing excess shoots in the first years of life. Flowers are large, 15 cm in diameter, blue, azure and cornflower-blue flowers. The depth of the color depends on the lighting, the larger it is - the richer the color of the flowers.

The tree is a great solution for beginning flower growers - after all, it is quite unpretentious. The main advantage is that it winters beautifully in the south, without requiring additional shelter, except perhaps for the first years. The tree is different from the shrub species, only in appearance - one trunk, which can branch at a height of about half a meter. The photo below is a young four-year tree. This is his second bloom.
An adult plant can grow up to 5 meters tall, even taller.

The leaves of the tree are large, bright green, flowers of medium size, bright color, there are also double, two- or three-colored.
Features care for grassy hibiscus
Watering, feeding, weeding, as in all species.
When autumn comes, the stem, leaves, withered flowers die off. Nutrients from them are gradually absorbed by the root system. This makes it more developed, strong, makes it easier to transfer the frosty winters.
That is why you should not prune the stems of grassy species before they completely wither. In the south, where there is often no natural shelter in the form of snow, you should correctly create an artificial one.
The first thing we do: we cut off the shrunken aerial part, spill water well, loosen, roll up the rhizome zone. You can sprinkle with humus or mulch. Sawdust, dead leaves, dry grass, coniferous litter will do. If it is needles, then in the spring it can be not removed, but left on top, slightly mixing with the ground loosening.
The resulting hummock from above should be covered with a white soft covering material, pressing it with stones or branches, erecting a kind of hut. When frosts are bypassed, carefully release the hemp plants from the warming pad, being careful not to damage the buds. After all, in May, young shoots appear, in which for pomp it is advised to pinch the tops.
Every three years it is necessary to divide the rhizome of the grassy hibiscus, so that its flowering does not weaken, it does not shrink. After all, every season the number of shoots is tripled. The struggle for nutrients, moisture becomes more difficult. In the first year of life, the number of main shoots is one, in the second two or nine, usually five, and three years later, there are already three times as many. It is time to divide the bush, which, by the way, is one of the ways of its reproduction.
Syrian Hibiscus Care
The adult shrub tolerates our Kuban winter well, and it is better to wrap the branches of a young pet (1-2 years) with white covering material, and sprinkle the area of rhizomes with humus or thoroughly mulch. The root cover layer must be at least 15 cm tall. Do not forget to free the plant from it in the spring!
Syrian species wakes up late enough, do not be afraid - it should be, it's just some of its features.
Shrub fertilizer loves phosphate (for example, Bud), which activate flowering. Closer to the fall, you need to start introducing potash preparations to prepare the shrub for wintering. Tree care is different only in that it can be not covered in winter. The exception is young saplings, which, nevertheless, the first 1-2 winters should be covered.
How hibiscus breeds
It depends on the species. For example, tree varieties can only multiply by cuttings, grafts, seeds.
Shrub, in addition to grafting, grafting, sowing seeds, can be propagated by layering.
Grass is easiest to reproduce by dividing a bush, but the methods listed above are grafted, and seeds are also inherent in them.
Reproduction by seeds does not pose any difficulty: it is produced like any sowing without any special tricks.
Works begin from January to March. First, it is recommended to soak the seeds for 10-12 hours in a solution of Appin. After that, wash them with a weak solution of potassium permanganate.
For sowing you will need a container, a mixture of sand with peat, as well as a shelter (glass, polyethylene or food film). Soaked seeds are sown in moist soil, covered. In order to keep the seedlings from waiting, you should keep the temperature around + 25ºС. Also, do not forget to air the container with crops, remove condensate drops, and if necessary, moisten the surface of the soil. After the shoots have leaves, they can be planted in separate pots.
And in May, stronger seedlings are moved to a permanent place, and their weak brethren on a temporary place - to grow.
When breeding seeds garden hibiscus bloom for 3-4 season. Remember, he may not keep the decorative of his parent. Therefore, seed multiplication is not the best way to purchase a flower with exactly those properties that you liked so much.
Propagation by cuttings is the most popular method among amateurs. It can be produced in two ways.
- Cuttings in the summer with 3-4 buds, dipped in water with the addition of Kornevin or another root growth stimulator. After the appearance of the roots, the cuttings are planted first in containers with peat ground for the winter, and in spring in open ground.
- Cuttings in the summer with 3-4 buds are processed by the root system growth stimulator in the same way as with the first method. But after that, they immediately land in greenhouse containers with wet peat for rooting. The cuttings that gave the roots are planted in pots for wintering, and in spring they are planted in open ground.
When grafting there is a high probability that your pet will delight you with its flowering in the very first year.
Propagation of garden hibiscus by dividing the bush is more suitable for grassy varieties. By the way, rhizome division is a necessary technique for the care of grassy species to maintain high-quality flowering. This is one of the fastest, most convenient ways to breed.
In early spring we carefully dig out a bush of 3-4 years of age with a fork, divide the rhizome with a knife or shovel. As a rule: one trunk - one separate plant. When dividing older bushes, 2-3 trunks are allowed per one new instance.
Sections sprinkled with ash or crushed coal.
The obtained parts of the rhizome should be planted immediately. Well spilled planting pits with nutrient soil should be prepared in advance.
Засыпаем корневища землей, утрамбовываем поверхность, опять поливаем. Через две недели можно проводить первые азотные подкормки. При таком уходе разделенные кусты быстро дают побеги, радуют своих хозяев цветением уже в первый сезон после посадки.
Reproduction by layouts and the method of vaccination should be left to professionals, since these methods will require not only skills and knowledge, but also special tools, patience, composure, that for gardeners-fans things are not always compatible. Especially when you need a fast, reliable result.
Hibiscus - omens, superstitions, traditions
There are more interesting facts that are impossible not to say.
It is said that this flower has magical powers.
Someone calls it a flower of love - supposedly it gives a huge amount of energy that can resurrect a departed love or light a new one in the family where it grows.

The same withering, drying plant supposedly portends a serious illness to one of the family members where it grows.
All this, of course, superstition. To believe or not is everyone's business.

Plant a garden hibiscus! Care and reproduction does not require much effort. Types and varieties of a huge amount. The color range will satisfy even the most demanding landscape designer. This wonderful plant will decorate your garden for many years, make it unique, amazing.
Garden Hibiscus Transplant
There is no special need for transplants of this plant. Unless, you were mistaken with a choice of a place or the plant was flooded and rotted roots. In grassy, hybrid hibiscus transplantation combined with the division of the rhizome, for which it is most often started. But if the need for transplantation has arisen, then it is carried out at the same time as the initial planting, but before flowering begins. Transplant technology is the same as for planting.

Planting hibiscus garden
The best time for planting hibiscus in the spring, when the soil warms up above 15 ̊C. With all winter hardiness, the species is quite sensitive to severe frosts, so it takes time to take root and grow strong.
For the good development of hibiscus ornamental shrubs, it is crucial to choose the right place, which should be warm, sunny and protected from the wind.
Like roses, the culture grows well on permeable, sandy soils with a high content of humus. The reaction of the soil from neutral to slightly alkaline.
Before planting a seedling, dig a hole 2 times wider than the size of the root ball. The distance from buildings and other plantations should be at least 1-1.5 meters.
Variety "Pink Chiffon"
At the bottom of the pit lay a 15 cm drainage layer of broken brick or crushed stone, then the same layer of coarse sand, which is sprinkled with compost mixed with earth. Place the roots in a hole and fill it with a prepared soil mixture from the top layer of the earth, compost, sand and peat, taken in proportions 2: 3: 2: 1.
If the soil is initially enriched with sand, then a drainage sand layer is not needed. The root neck after planting should be slightly below ground level. The seedling is well watered with about 7-10 liters of water.
Immediately after planting a garden hibiscus, you should cut all the shoots in half. This procedure, reluctantly performed by gardeners, is aimed at the formation of a dense and lush crown, as it stimulates the growth of new shoots.
The plant grows in one place for about 20 years, so hibiscus transplantation is carried out only when absolutely necessary and only young specimens.
Features care for Syrian hibiscus
Syrian rose is unpretentious in the care, it is enough to follow a few rules of cultivation, so that the green pet every season pleases you with magnificent flowering.
Gardeners recommend putting a thick layer of pine bark mulch around the plantations. The mulching procedure helps protect the roots from freezing, reduces evaporation and controls weed growth.
Tree hibiscus requires a constantly moderately moist substrate without stagnant water. Watering is carried out regularly, not allowing the soil to dry. However, do not overdo it, since excessive irrigation causes the development of root rot.
To avoid problems, the top soil layer should dry out between irrigation. Deep watering once a week in the absence of heavy rain will be enough. In the dry and hot summer, water is watered every 1-2 days. Watch for flowering - a deficiency or excess of water can lead to abscission of flower buds and buds.
After watering in the summer, so that the earth does not take a crust, spend it loosening. The procedure provides access to oxygen to the root system of the plant.
In the care of hibiscus tree also includes the regular removal of faded flowers, which stimulates a longer and more intense flowering.
Due to abundant flowering, the plant requires multicomponent dressings with a predominant phosphorus content, which stimulates budding.
Feed every two weeks, starting with the beginning of June and ending no later than the end of August, so that the plant has time to prepare for winter. Potash fertilizers are added to the last feedings. It is also useful to mix the compost with the soil once a year in the spring and sprinkle it around the bush.
Problems in the care
With proper care and cultivation of tree hibiscus, the culture is quite resistant to diseases and pests. However, increased air humidity can lead to the development of powdery mildew or fungal leaf spot, which is manifested by brown spots.
Gray mold also occurs due to high humidity, causing the flower buds to rot, the leaves wither and fall, the shoots die off.
Diseases are treated with fungicides. For prevention, water the plantings in the morning and just below the root, ensure good air circulation around the bushes.
It is also possible infection by fungus rust, which causes yellowing and leaf spot. The disease is characterized by yellow-orange pustules on the lower surface of the leaf. Affected leaves are removed and burned.
Quite rarely a plant can attack spider mites and aphids.
Possible difficulties in growing
The most harmful pests that can attack a garden hibiscus are aphids and spider mites. That is the same parasites that attack roses. But if you plant a lavender near it, and plant geraniums nearby for the summer, it will not only be beautiful, but also scare away aphids. If this helps little or you don’t have such plants, you can use these tips. It is somewhat more difficult to fight spider mites. Methods of dealing with it on garden flowers are almost the same as on indoor plants (read how).
In addition to aphids and mites, thrips and whitefly can be expected. Against them there are a lot of systemic drugs.
If gardening hibiscus care is correct, then the disease is bypassed. Most often growers have to deal with chlorosis. But it is rather not even a disease, but a plant response to a lack of iron and nitrogen. In case of chlorosis, the leaves of hibiscus, starting from the bottom, turn yellow and fall off, and the young leaves already initially appear veined with a yellow tinge. To avoid this, do not ignore plant nutrition. But if signs of chlorosis appear, then start additional feeding with iron chelate. And it is carried out both under a root, and "on a leaf", spraying. Doses and frequency are usually described in detail in the instructions for the drug.
Hibiscus leaves turn yellow not only because of chlorosis. The reason for this may be overdrying of the soil. Enough to increase watering and everything is normal. Yellowing of hibiscus leaves can also be the result of a root injury (for example, during transplantation or inaccurate loosening of the soil). In this case, the roots need to be strengthened by adding a little root-stimulator to the water during irrigation (“Kornevin” will work well). The same solution is desirable and spray the leaves.
Why do garden leaves have hibiscus . If the fall occurs closer to winter, then this is a completely normal, natural phenomenon. Syrian hibiscus and similar plants are deciduous plants, and in the grassy hibiscus, in the fall, the entire aboveground part of the plant dies. But if the leaves began to fall ahead of time, it means that something is wrong. As a rule, the untimely fall of the leaves of hibiscus is preceded by their yellowing. Therefore, the causes and methods of treatment are the same as for yellowing. I also recommend inspecting the plant for pest damage.
