Primula is a perennial herbaceous plant of the family Primula. The root system is superficial, it grows quickly. The height of the stem is 10-25 cm. The leaf plates are whole, wrinkled, are collected in the rosette, painted in dark green. Primula is grown as a decorative flowering plant. Flowers of the correct form, consist of 5 petals, rise above the bush on a short peduncle, are located singly, or racemes are clustered, umbrella-shaped inflorescences. By color varied.
Usually flowering begins in spring, but varieties that bloom in winter are bred.
In the natural environment it lives in the temperate climate zone of Europe, Asia, North America, China, where it grows on moist soil near water bodies.
Growing room primrose from seeds at home

Primrose is propagated by seed and vegetative way. Sowing time depends on the variety of primrose. In general, it is the period from the middle of spring to the beginning of summer.
- Fill the container with a mixture of leafy earth and sand, spread seeds as rarely as possible over the surface of the soil, without digging, otherwise they will not grow.
- Spray from the pulveler. For successful germination cover crops with glass or film.
Primula room cultivation from seeds at home photo shoots
- Place in a bright place with a temperature of 16-17 ° C.
- Shoots will appear in a couple of weeks. Shelter must be removed.
- Lighting and air temperature remain the same.
- Water moderately, thin out as you grow.
- After about 3 months of life, young plants will get strong enough, then plant them in separate containers.
Primula room seed at home
- When transplanting into individual cups, use something as a scapula, for example, a fork, to gently pick up the seedlings with an earthy clod, without disturbing it, and transfer to a more spacious container.
- Transplanted plants watered gently.
- Further care is simple: moderate moisture and heat are needed, diffused lighting. When the violets grow up, they are rolled into permanent pots.
Propagation room primrose division bush
During transplantation, carry out the division of the bush. For this fit plants not younger than 3 years. Remove the primrose from the pot, divide it into 3-4 parts, the volume bush can give up to 6 delanok. Seat in small pots. To create a greenhouse effect, cover with foil. When delenki root and go in growth, you may need to re-transplant. At each transplant, remove dried leaves, apply complex mineral fertilizers.
Propagation of primrose leaf cuttings
Cherenkovy spend spring or autumn. Separate part of the shoot with a growth bud and leaf. Shorten the leaf in half. Root in a mixture of leaf earth and sand. The lighting will need diffuse, maintain the air temperature at 17 ° C, water moderately. With the advent of 3-4 leaves transplanted into a pot with a diameter of about 10 cm.
How to water
During flowering soil should be constantly slightly wet. The rest of the time, water as the top layer of soil dries. Do not allow excess moisture. It is better not to water it once again - the leaves may swell, but the plant will quickly recover after watering. Use bottom watering or add water, moving along the edge of the pot so that water does not fall on the leaves of the plant. Water with soft water at room temperature.
Spray the plant can not. To maintain humidity, periodically place the plant pot on a tray with wet moss, pebbles, expanded clay.
Room Primrose Transplant
How to transplant primula in a pot photo
Replace hold every year in spring or early autumn. Soil: a mixture of turf land, peat and sand. Lay a drainage layer about 2 cm thick at the bottom of the tank.
Capacity pick a wide, shallow.
Remove the primrose from the pot, inspect the roots, remove the diseased, damaged roots, treat the cut sites with a fungicide. Place the plant in a new pot, fill it with soil to the brim, compact it a little, pour it.
Suitable for this plant age 2 years. It is necessary to place a primula late autumn in a dark place with an air temperature of about 3 ° C. Do not water. Usually they want to get bloom by March 8, so proceed to the next steps in late January and early February. Replant the primroses. Provide diffuse lighting, air temperature within 5-10 ° C, water moderately. With the advent of buds, start feeding.
Room primrose diseases and pests
Rust, jaundice, anthracnose, powdery mildew, cucumber mosaic virus, tomato spotted wilt virus are possible primrose diseases. To save the plant, it is necessary to remove the damaged areas and treat it with a fungicide.
Plant pests: nematodes, spider mites, aphid. It is necessary to carry out treatment with insecticide.
Primrose leaves turn yellow and fall buds
- Due to excess moisture, rotting of the root system and stems is possible. Make an emergency transplant. Remove the affected areas, treat with a fungicide. Watering adjust,
- The leaves turn yellow. This happens for a number of reasons: high temperature or dry air, the soil is over-humid, watered with hard, cold water, excessive feeding,
- Reset buds, flowers fade quickly. Dry air, elevated air temperature, lack of moisture in the soil.

How indoor primrose differs from its wild congener
This relative of primroses lives on almost every continent. There is it even in our forests, and it looks like this:
Such a primrose (it has a lot of popular names, for example, in Ukraine it is called "God's handles") does not really resemble its cultural, indoor relative - except leaves.
Still would! What we grow in pots was brought from China.
Sometimes this plant is confused with a baroque violet, which also has fluffy leaves and flowers of a slightly similar shape. But primulas in the middle of the flower always have a bright yellow throat, and in violets there are only yellow stamens:
Pluses cultural primrose:
- they can simply conquer you with an abundance of colors (there are even two- and three-color primroses),
- there are a lot of flowers on a bush - as Saintpaulia fans would say, this is a solid nodding bloom,
- bloom primroses room for quite some time.
But remember! These flowers are not always perennial. Among the primroses there are two-year and even annual species.
So when you buy, always specify what exactly they offer you. After all, if you like a flower, you will need to have time to multiply it. How? Read below!
Is domestic primrose dangerous?
Not everyone knows, but yes! The leaves of this ornamental culture are poisonous. Therefore, it is better for young parents to put a pot with a plant not on a window sill (where the younger generation walks without difficulty), but higher. Well, of course, in the nursery to keep this flower is not worth it.
Moreover, such a flower is not recommended for allergy sufferers (especially the indoor view of the obkonik, which we are just talking about), as it may not please their body.
But even if you do not consider yourself to be particularly sensitive people, after any work with this flower, wash not only your hands, but also all the tools used. Ideally wear disposable gloves.
Interestingly, our native wild primrose, on the contrary, is not harmful, but very useful. Many people are not averse to feast on its leaves - maybe they don’t taste good, but there is a lot of vitamin C in them.
What kind of care does this flower need?
- Lighting. The light around the flower should be bright, but diffused. Direct sun can cause primrose damage in the form of sunburn. Therefore, the western or eastern window is considered ideal for this culture.
- Temperature. Primula - "walrus" among the flowers. If she grabs 20 degrees in summer, then in winter and spring (just when the plant is flowering) in a room with a pot should be from 8 to 12 degrees. By the way, if you land primroses on a flower bed for the summer, you can leave them here for the winter - unless, of course, the climate in your area is not too frosty.
- Watering. The flower is very capricious to water - it takes only rain, thawed or 2-3 days separated. Before flowering (as in time), water the flower little by little, but often - so that the soil is always slightly wet. The key word is “slightly”, that is, without puddles and swamps. When the flowers fall off, get a watering can less often, only when you see that the top of the ground is dry.
- Humidity in the room. She must be tall. Spray frequently (but only leaves, not flowers), you can keep the pot on a pan with well-watered clay or pebbles. If the tips of the leaves of primrose dry, this is a sign - the air is too dry, the plant suffers, an urgent need to solve this problem.
- Nutrition. This kind of color can suit a highly diluted complex mineral fertilizer. It is possible to make such a “treat” only when the plant is already “hung” with buds - right up to the end of flowering.
- Disease. Primula susceptible to infections, fungi, attacks of malicious insects. Primroses most often suffer from powdery mildew or spider mites. Of course, these situations can be corrected by spraying with solutions of modern chemicals - but flowers with a “tarnished reputation” should not be transferred to the house, so that they do not infect your pot. By the way, full-room primroses are sick less often than their garden relatives.
Sometimes people give primroses for spring holidays, and they (like most purchased flowers) quickly wither and disappear. How to prevent the death of a beautiful plant, tell the florist:
It is necessary if your flower is a perennial, because when transplanting, the old, depleted and already fairly “empty” soil is replaced with fresh and “tasty”.
- Priming. If the store does not have soil for primroses, buy a substrate for geranium, it is also suitable. Are you a perfectionist? In this case, mix the soil yourself. Here is the recipe: turf, hardwood, sand and peat (in equal quantities). Here is a simpler recipe: mix your garden soil (if it is of neutral acidity) with coarse sand.
- Pot. It is necessary wide, but not deep - the root system of the plant is quite compact and the whole is on top of the soil.
Do not forget about the drainage! Only 1-2 cm of expanded clay, pebbles, gravel at the bottom of the pot will protect your soil from waterlogging. Although, of course, this recommendation applies in general to all modern flowers and even vegetable seedlings ...

What is the cultivation of cultural primrose
If you do not grow Obconik primrose (that is, only a room view), every spring the plant should be transferred to the garden / open ground, and dig it out in the fall and return it to the house. If you keep primroses in the house all year round, they become deranged - first they stretch strongly upwards, and then they begin to dry out.
However, most primroses can be kept "in the wild", that is, in the garden, all year round. But once in 2-3 years they are made forcing, "expelling" the plant from a flower bed and forcing it to bloom at an unusual time.
Everything is done like this:
- As soon as the first frosts strike, scoop up the primula and transfer it to the flowerpot using the transshipment method (drainage, soil - everything is as it is written above). It is best to take a young plant (a seedling that is 2 years old), and if it is not there, a delenko from a mature bush.
- Put the pot in a cold place (closed but unheated balcony, or even better - the cellar). Ideally, around the pot kept temperature no higher than 5 degrees. Do not water the plant.
- In late February - in early March, bring the pot into the house. Heat it, start watering, you can feed it. The flower will quickly respond to such care with the active growth of foliage and lush flowering.
- When the bush blooms, you can bring it back to the flower bed.
Room primrose: description
Primula is a perennial herbaceous plant, attributed to the family of primrose varieties. This flower is known almost all over the world and has at least five hundred different species, differing in size, color and duration of flowering.
- Garden primrose can bloom twice a year - at the end of winter, the beginning of spring.
- Bush height may have a length of about 25 centimeters.
- It happens to be perennial, annual, and two-year, depending on the type of home evening primrose. However, experienced growers, most often, prefer one-year varieties.
- Primrose inflorescence has five petals, at the end of which there are three blades.
- Possesses a fibrous root system and an extremely short stem.
- Rosette castings have a pleasant green shade and a hairy surface. Can reach seven centimeters in diameter.
- As for the flower itself, it is relatively small in size - from one and a half to four and a half centimeters, depending on the species.
- The fruit of the plant has the form of a small box.
- Primrose flowers are distinguished by a wide range of colors: red, blue, pink, lilac, yellow, white; however, despite the wide variety of palettes, the flower pipe's mouth remains always yellow.
- The flower can be garden and indoor, and primrose grown in garden conditions, not always suitable for breeding at home.
The main nuances of primrose care
Before you buy a flower crop, you should understand the basic rules for growing this gorgeous flower.
- The flower is unpretentious in the care. However, it should be remembered that he very badly tolerates drafts and darkness. Therefore, it should be placed in a bright room, but so that direct sunlight does not fall on its surface. An ideal place for flowering primrose is the northern or western part of the apartment.
- Grow primrose best on the windowsill near the windowso that later you can enjoy how it will bloom for a long time.
- Caring for a primrose room includes good soil selection for planting. It is best to acquire fertilized soil in specialized stores. Although if you wish, you can cook it yourself. To do this, you need to take any neutral soil and sand, mix everything up and you can plant a plant. You can also use a mixture of peat, fine sand and a substrate of turf or hardwood.
- In order for the primrose to have a gorgeous bloom, one more condition must be met: timely eliminate dry leaves and flowers, as well as systematically pluck dried stalks.
- Flower requires mandatory feeding. It is better to do it once every fourteen days. An important nuance regarding the top dressing: the flower should be fertilized only after its inflorescences form. Otherwise, the primrose will begin to give all its juice to the development of leaves, and not to the formation of flowers. As a result, the flowering process may be significantly delayed. The plant responds well to dressing from bird droppings, organic fertilizers and ammonium nitrate.
- A suitable temperature regime for growing primroses at home is 12-16 degrees - in this case the plant will have a longer flowering period.
- Care includes compulsory watering. However, it is impossible to prevent the liquid from getting on the leaves, as they may rot. Watering should be moderate and only under the roots, and only in the case when it is clear that the ground has dried up under the flower. However, in the flowering process, an abundant mode of watering is required, but so that there is no stagnation of the liquid in the pot. Water for irrigation must be at room temperature, but not in cold.
- Room primrose is very demanding on the mode of humidity in the room. Comfortable conditions for care and cultivation is considered increased humidity. If the room is not enough, it can lead to the fact that the leaves of the plant will begin to dry, and the flowering period is significantly reduced.
- Caring for a plant in a dormant period, when there is no flowering, involves systematic watering, placing the flower in a dark and well-ventilated room, cutting dry leaves and maintaining a temperature range of 10–16 degrees. It is likely that with this approach, the annual plant will bloom again. If the primrose is perennial, then at the end of flowering, it will need to be transplanted.
Compliance with these simple rules of care for the primrose, will allow you to grow a healthy and beautiful plant, which will bloom profusely every year.
In decorative floriculture such types are popular:
- Primula obkonika. This species is suitable for growing in indoor conditions. A perennial shrub about half a meter high has rounded leafy plates on long petioles. The fragrant flowers of primrose with a diameter of about 4 cm are painted in pink, purple, snow-white, red or blue. The varieties "Libre Magenta" and "Libre White" are awarded by the Royal Horticultural Society of Great Britain.
- Primula Kyu. Annual is about 30 cm tall, with rounded leaves up to 20 cm long. Small fragrant flowers are collected in umbrellas inflorescences. The only species that has flowers of yellow color.
- Chinese primrose. Perennial with a rosette of leaves, plant height - up to 35 cm, leaves - up to 15 cm in length, blooms with buds of various colors, which have a yellow spot in the center.
Most often on sale you can find a primrose hybrid, which can only grow in the garden. When grown in room conditions, it disappears after flowering, you can save it by transplanting into a flower bed.
Features of growing
The temperature of growing a flower is low, during winter flowering it is desirable that it is 12 - 15 ° C. It is difficult to provide such conditions in a city apartment. Primula obkonika feels good at + 18 ° C. Perennial varieties can be planted in the summer in the garden, and in the winter to bring into the room.
It is necessary to cut off the yellowed leaves and wilted flowers. This will allow the plant to bloom longer, as the forces will not be spent on setting seeds.
Primroses love bright light. It is necessary for plants especially strongly in the winter, during flowering. In summer, on the south windows you need to make sure that the flower does not overheat, it does not tolerate air temperatures above + 24 ° C.
Abundant watering in winter distinguishes primroses from other plants that need at this time in relative or complete rest. Water with clean, settled water as soon as the top layer of soil in the pot dries out. It is advisable to use water passed through the filter, rain or key - the flowers do not tolerate impurities of chlorine and fluorine.
Pests, diseases and treatments
Primula at home often suffers from fungal diseases that cause root rot and leaf wilt. Insect pests on it rarely settle. Yellow spots on the leaves along the veins can talk about chlorosis. This is due to improper feeding of the plant or watering with hard water.
Evening primroses can also die from the fact that it is very cold on the windowsill. In this case, after watering the roots do not absorb water well and can rot. In wet cold soil, fungal infections develop faster. You can put in the winter on a cold window sill foam or a plate to keep the plant warm.
When heating is turned off, it is advisable to water the flower with fungicides for prophylaxis.
New plants are quarantined, separately from other indoor plants. In order to get out the primula bought at the store, it is sprayed and watered with “Fitosporin” several times with a difference of 10 days.
How to propagate primula room
Propagated by dividing the plant bush at the time of transplantation or seed. The second method is more difficult, it requires patience and knowledge. The seeds of the plant quickly lose their germination, this must be taken into account when purchasing them in the store.
Growing most primroses from seeds requires stratification. Seeding procedure:
- In flat dishes filled with universal soil and vermiculite (in equal parts), seeds are laid out,
- from above sprinkle them with a layer of soil about 2 mm,
- put the containers in a bag and put them in the freezer,
- at a temperature of –12 ° C, seeds are stored in the freezer for a month,
- in a month, the containers are removed from the refrigerator and put on the window sill, in the shade,
- moisten the soil with a spray bottle and air the seeds 2-3 times a day,
- germination temperature should be no higher than + 18 ° C,
- when the seeds germinate, the container is transferred to a well-lit, warm place (+ 20 ° C).
Seedlings are watered and fed during forcing, like adult plants. Dive it in separate pots in a month after germination.
Possible problems when growing indoor plants
Because of errors in the care leaves fade and flowers, buds fall. Fertilizers and growth stimulants will not help when the plant begins to wilt in the wet ground. This suggests that he has roots and needs treatment with fungicides, for example, Fitosporin, Maxim or Fundazole.
The treatment must be repeated several times so that the plant fully recovers. When the leaves cease to wither, and new ones begin to appear, we can assume that the plant is already healthy. As a preventive measure, "Fitosporin" is useful even for healthy plants - it will support their immunity and prevent fungal infections from developing in the soil.
If the air in the room is too dry, dark spots appear on the tips of the leaves, little buds or they fall. In this case, the plant will help spraying the leaves.
The abundance of large leaves and weak flowering suggests that in fertilizers a lot of nitrogen or primula stands in a room where it is too warm and there is little light. High air temperature also contributes to the fall of the buds. To remedy the situation, primrose rearranged on a cool, bright window sill or carried out on a heated loggia.
It is recommended to keep in a cool room. So, when the plant blooms, it needs a temperature of about 12-15 degrees. Primula obconica prefers a higher temperature (16–20 degrees). After it ottsvetet, it is moved to a cool room or transplanted into the open ground, while choosing a shaded place. In the last summer weeks, primula obconica must be moved to the room.
Prefers diffused light. Scorching sunlight can harm this flower.
There are no special requirements for air humidity. However, if it is too low, then in some species of primrose, the edges of the leaves begin to dry. Systematic spraying of foliage is recommended, and use soft water to do this.
For distillation, as a rule, take a two-year bush or an older divided plant. You need to dig a flower just before the frosts, and you need to take it with a large lump of soil. Primrose can immediately be planted in a flower pot or put for storage in a box. For storage, the plants are placed in a greenhouse, closed for the winter period with frames and dry leaves, or in the basement. The temperature there should be about 4-8 degrees. If it is warmer or lighter, only foliage will grow intensively. The development of buds at the same time will be slow or completely absent. Watering plants is not necessary.
In the last weeks of January, the first - February, you need to put a primula in a bright room, where the temperature will be no more than 18 degrees. In this case, watering should be resumed gradually. There are species that begin to bloom in February, on other flowers appear in March or April. To prolong flowering, it is necessary to place the primrose in a room with a temperature not higher than 10–15 degrees.
After flowering, these plants are not discarded. They are placed in a bright, cool place and provide moderate watering. In the spring they are transplanted into the garden. After 2 or 3 years, these primroses can again be divided and used for forcing.
Room primrose: rules for transplanting at home
If room primrose refers to perennial varieties, the faded plant will definitely need a subsequent transplant. Do transplantation should be annually after the next flowering. The transplant process is carried out in several basic steps.
- For the right transplant, you need to pick the right pot - a new place for growing a flower, it should be an order of magnitude wider and larger than the previous one.
- The container in which there is a faded plant, you must gently turn upside down. Lightly tap on the back of the pot and pull the plant, but so as not to damage the root system and break the stalks.
- Garden flower before transplanting into a new pot, requires mandatory rinsing of the roots. If the primrose has diseased or damaged stems and roots, they should be carefully removed in order to subsequently prevent infection of the flower.
- Further, it is necessary to pour a new drainage and soil into a large pot prepared in advance. It is impossible to use the land in which the primula was previously grown. The soil should be fresh.
- After that, the plant is installed in the soil, completely covered with the remnants of the soil and slightly compacted.
Transplantation is best done in the fall - the end of September. It should be remembered that young flowers are required to replant once a year, while adults - once every two years.
Room primrose: seed propagation
The most popular way of planting primrose room, is the cultivation of annual flowers with seeds.
- Ready-made seeds can be purchased in specialized stores or independently collected from faded plants.
- As the soil, you can use the purchased soil or prepare a mixture of sand and hardwood.
- Existing seeds should be evenly distributed over the soil surface, then thoroughly watered and covered with foil or some kind of glass container to create a greenhouse effect.
- Planted seeds are carried in a pot in a bright and cool place for a maximum of two weeks, until the first sprouts appear.
- After the primrose flower has sprouted, the coating can be removed and the plant left open. However, it should be kept not in a warm place, but in a cool place.
- As for the care, it includes watering, which is recommended to be carried out no more than once a month.
- When the sprouts grow significantly, they can be safely seated, after having thinned out.
- And only after 90 days, when the flower stems become strong, and the root system is fully formed, it is possible to repot the indoor plant in separate pots.
Room primrose: reproduction by cuttings
In this case, growing a flower involves using lateral stems.
- A small pot is prepared in advance, into which sand and peat should be poured with a thin layer of no more than 2 centimeters.
- Cut the stalk at the same time as the leaf and bud.
- The leaf at the same time is cut exactly half, and the cut must be smooth without any errors or notches.
- Next, the petiole is inserted into the soil approximately 1 cm deep and at a slight angle.
- Then the soil is abundantly watered.
- A container with a planted flower should be carried to a dark cool room, for example, to a balcony. Watering should be systematically, not allowing strong drying of the earth.
- About three months later, after the stalk has hardened and put down roots, the first leaflets will begin to appear on it - about three or four pieces. As soon as this has happened, it is necessary to transplant the plant into a more capacious pot.
Room Primrose: reproduction by division
As for this technique of growing a flower, it is made only after the room primrose completely fades.
- First, all rotten or dry leaves are removed from the flower, after which it is placed in a cool, dark room. Do not overdry the soil.
- The process of division can only begin after the flower begins to grow strong stems.
- After that, the plant must be carefully removed from the pot so as not to injure the root system.
- The withdrawn bush is divided into two or three identical parts, which should be seated separately in different pots and watered well.
- For the normal growth of the flower, it is required each of the pots, where the flowers are already planted, cover with glass container and put in a cool, bright room.
- When the plants take root, and noticeably begin to grow, they are required to plant in more capacious pots.
- In the process of transplanting you need to make sure that there are no dry leaves on the flower, and there are no damaged roots.
- To bloom was long, and the flower grew normally, it should be systematically fertilized with minerals. The first time, it needs to be done once every two weeks.
Primula room: symptoms of plant disease and how to eliminate them
To find out that the plant has been attacked by pests or affected by diseases, it is possible by the primary signs:
- sick flower sharply leaves start to rotthat may be the result of frequent and abundant watering, as well as improper watering, as a result of which, the liquid fell on the leaves,
- improper room temperature can cause the flower to wither and drop leaves and petals,
- if a the flower starts to turn very yellow, it can be a consequence of dryness of the soil and improper level of humidity of the air, as well as the reason may be an oversupply,
- As for the defeat of the flower by pests, the most common diseases are: damage by aphids, spider mites, whitefly or weevils. In this case, the leaves appear characteristic spots and plaque. For treatment, it is required to tear off all the affected leaves, and then treat the plant with “Topsin” or “Fundazole”,
- powdery mildew, most often, it affects garden primroses, although there are cases of infection of indoor plants. The first sign of a lesion is the appearance of a white plaque on the leaves, which is called late blight. With this state of the plant, the rotting of the root system and flower stalks begins, as well as the sharp yellowing of primrose leaves. It is possible to get rid of infection by treatment with special insecticidal preparations. For example, Bordeaux liquid or copper oxychloride.
- If the flower struck gray rot - the plant rots, and flowers and leaves dry and fall. Therefore, primula should be treated with copper oxychloride, and the affected parts of the bush removed.
If it is noticed that a primrose room has symptoms of a lesion, it should be isolated from other colors so that the disease does not spread to them. If the processing plant did not bring improvement, flower will have to throw, as it will never bloom again.
Popular room primrose varieties
The most popular varieties of room primrose:
- Snow Queen "- inflorescences whitish shades,
- Mars - purple inflorescences,
- White pearls - white flowers with pearl tints,
- Eclipse Violet with Rim - lilac flowers with a gold border,
- Juliet mixed - has double-colored terry inflorescences - purple and pink,
- Enchantment - bright blue inflorescences.
Propagation room primrose seeds
Initially, it is necessary to obtain the seeds of this plant, for this purpose, the primula is artificially pollinated. If you have homemade primrose seeds, first disinfect them. To do this, it is necessary to select the seeds and dip them into hot water for 15 minutes, then for another couple of minutes - in cold water. Then dry them well. It is possible to buy primrose seeds in the store, there is no need to do an additional procedure of seed disinfection, the manufacturer has already taken care of this.
Primrose seeds are sown in summer in shallow pots or containers. The soil in the tank must be moistened. Distribute the seeds on the surface of the soil, lightly sprinkling with soil. After the seeds of primrose have been sown, they need to cover the film or glass. Do not forget to air. With proper planting, shoots appear in 2 weeks. As soon as the seeds germinate, move the containers with them to the window sill, then place the lamp over them. A month after the emergence of shoots dive, that is, transplanting into separate pots. This is one of the most important stages of growing primroses. When the transplants are completed, begin to apply a complex-type fertilizer during watering.
Watering and dressing room primrose
This flower can be fed with weak mineral fertilizers. A good time for feeding is primrose flowering time, fertilizing it once every 2 weeks. If you feed a primrose with fertilizers before flowering, then only green mass will increase. When the primrose is in rest mode, it is better not to fertilize, since it does not particularly need it.
When the primrose blooms profusely, it needs abundant watering, but it is also not necessary to flood the plant so that the roots do not start to rot. For watering primrose need water at room temperature. Watering is necessary with settled water. Также поливайте аккуратно, чтобы капельки воды не попадали на листья примулы, а то они начнут гнить.
Какими должны быть освещение и температурный режим при выращивании комнатной примулы
Примула – теплолюбивый цветок, который любит хорошее освещение. But direct sunlight for a primrose can also be disastrous, since the leaves of primrose are very tender, burns can form from direct sunlight. Better all the plant feels on the windowsills on the west or east side.
The optimum temperature for growing primroses should be: in spring and autumn - + 20 ° С, winter - + 18 ° С, during flowering period - from +16 to + 20 ° С. If you have created optimal conditions for growing primroses, then its flowering will be abundant and long.
Distilling primrose at home
