Hibiscus are represented by an extensive species diversity. Depending on the classification systems and the country of compilation of the plant classifier, there are from 150 to 300 species, most of which are wild trees and shrubs. However, there are several hibiscus known to lovers of room floristry, the most popular of which is without a doubt the "Chinese rose" or Chinese hibiscus. It can be found both in greenhouses and at home - in the winter garden or on the windowsill. Abundant greenery and large flowers of bright colors, he is able to decorate any room. But it happens that, despite the growth of the plant, he stubbornly does not want to bloom. As a rule, this is due to improper or insufficient feeding of hibiscus, which is designed to give it strength and health. Below we will consider the main ways of fertilizing this plant so that it will please the eyes of its owners for many years.
Basic principles of feeding hibiscus
- Feeding hibiscus should be done once or twice a month. Once - in the cold season (October-March), twice - in the warm season (April-September).
- Top dressing is desirable to carry out in cool and evening time. This will allow the process of absorption of nutrients by the plant and their distribution in the soil to take place most naturally and without the release of harmful substances that can be formed in the heat or under the influence of direct sunlight.
- One or two hours before top dressing, the soil is abundantly shed with settled water at room temperature.
The main ways to feed hibiscus
- Manure. Natural organic fertilizer that is suitable for most plants, as it contributes to the enrichment of the soil with the main useful elements. It should be borne in mind that a large amount of organic matter is harmful and it is important to observe the measure. With regard to manure, the following guidelines should be taken into account: you can not use fresh, it must lie for several days (ideally, dry a little); no more than two tablespoons can be used per two liters of soil; You can feed the plant with manure, starting from the year of life.
- Peat humus tablet. Another analogue of manure, which allows you to safely and effectively nourish the soil and plant.
- Regarding mineral fertilizers, hibiscus primarily requires phosphorus, nitrogen and potassium, and it is desirable to observe the following proportions: 1:2:3 (phosphorus:nitrogen:potassium, respectively). To meet the need of plants for phosphorus, you can use bone meal (the safest option). Urea is the best source of nitrogen. Kalimagnesia has shown itself well, also contributing to the saturation of the plant with magnesium, which makes it more stress-resistant, preventing leaf fall and excessive yellowing. You can also use complex fertilizers for greenhouse and house plants.
Just a few minutes a month devoted to feeding hibiscus will allow it to grow strong and healthy and delight the eye not only with lush greenery, but with luxurious buds.

Lilies are so beautiful and graceful that almost every gardener tries to plant this plant in his garden or flower garden. However, to achieve lush flowering of lilies is possible only with proper care. In addition to the requirements for soil fertility, lilies also need periodic fertilizing, regular loosening and watering.
How to feed lilies and how often should this be done?
As soon as the earth warms up under the spring rays, they begin to care for the plantings of lilies. Gently loosening the top layer of soil, trying not to damage the bulbs, apply any fertilizer that activates the growth of the plant. What can be used?
- Nitrogen fertilizer. So, you can use ammonium nitrate, scattering a tablespoon of fertilizer per square meter of plantings. If there is no ammonium nitrate, gardeners scatter nitroammophoska granules over the lily plantings or pour it with a fertilizer solution (40-50 grams are taken per bucket of water).
- organic fertilizer. Fresh mullein is not used because it has an aggressive pathogenic microflora, due to which lily bulbs become sick and die. Fermented mullein diluted with water in a ratio of 1:10 is used for top dressing.
- Ash water. A glass of wood water is dissolved in a bucket of water. This fertilizer improves the microflora in the soil, it is also a prophylactic against pests and has a beneficial effect on the growth of lilies. Wood ash is applied to the soil in spring, and lily plantings are watered with ash water until autumn 3-4 times. With sufficient ash content in the soil, the lily forms large buds.
- Bordeaux liquid. In early spring, when the lily begins to actively gain green mass, the flowers are treated with Bordeaux mixture. This is an effective remedy that rids lilies of many pests. Instead of Bordeaux liquid, you can use Lazurin. It is diluted in 9 liters of water, a spoonful of baking soda, ammonia and copper sulfate are added to the resulting solution.
With the advent of the first lily buds, you again need to feed with ammonium nitrate. In parallel, the green mass of plants is treated with preparations from various diseases and pests.
In June, a solution of double superphosphate and potassium magnesia is added under the lilies (a spoonful of superphosphate and 1.5 tablespoons of potassium magnesia are taken in a bucket of water).
Planting lilies often suffer from gray mold, but even in this case, lilies should be fed with fertilizers. The bulb continues to accumulate nutrients, so top dressing is especially important. With such a disease, feeding with ash will improve the situation, since it effectively fights pathogenic fungi.
After flowering, lilies are fed with superphosphate and potassium sulfate, which allows the bulbs to ripen better by autumn. These are the last top dressings, later the plants are treated only with Bordeaux liquid to prevent the development of diseases.
In order for the lilies to overwinter well, the flower bed must be covered with rotted compost or leaf humus with a layer of 10 cm. In the spring, such a shelter is not removed, using it as mulch.

Top dressing hibiscus
It so happened that in recent years several new hibiscus have settled in my apartment. The beauty of their flowers is fascinating, but at first there were enough problems with them. Now I understand that all the difficulties were caused by care errors, namely: non-compliance with the rules of dressing. Fertilizers for plants are like vitamins for us humans. You can help or hurt...
Having finally figured out the nuances of fertilizing, I got rid of the main problem, and my hibiscus again became strong, healthy and blooming luxuriantly. I feed them according to the dosage on the label all year round: once a month from November to February and twice a month from March to October. Fertilizers are mostly organic (humisol, vermisol), and only occasionally do I use a full mineral fertilizer (so as not to burn the hibiscus roots - no more than 4 top dressings per year).
The most intensive top dressing of hibiscus I spend, of course, in the summer months - these are root top dressings and leaf spraying. During flowering, I also use various ready-made fertilizers for flowering houseplants. That's just in their dosage I follow the rule "better less, but more." I want to draw the attention of flower growers to the fact that phosphorus-containing fertilizers ensure the development of flower buds and, accordingly, more abundant flowering. Nitrogen and potassium enhance leaf growth.
I try to fertilize on cloudy days or in the evening. Before that, 2 hours before the procedure, I must spill the earth in pots with ordinary clean water. I prepare a nutrient solution of fertilizers in settled water at room temperature. Some time after watering and fertilizing, I will definitely loosen the soil in pots.
A healthy appearance of plants, the appearance of new leaves and buds confirm the timeliness and correct dosage of dressings. So, yellowing, wilting of leaves, the appearance of spots on them, falling buds against the background of proper care and maintenance indicate overfeeding. Do not allow this, do not force your hibiscus to experience stress, because this will adversely affect his health.
I wish all your plants to be beautiful, strong and healthy!
In the spring, when transshipping strong and healthy hibiscus, granular rose fertilizer can be added to the earthen mixture. In this case, a month and a half other top dressing should not be made. Remember: an excess of fertilizer does not help, but rather inhibits the development of plants.

Indoor hibiscus: care, transplantation, reproduction, flowering
indoor hibiscus
The hibiscus plant was well known in ancient Greece. However, then this name was called mallow. Hibiscus is known today as Chinese rose. The plant is loved and revered on many islands that are located in the Pacific Ocean. For local residents, hibiscus inflorescences are an exquisite hair ornament. Apparently, this tradition gave the name to the plant, since in translation "hibiscus" means "a flower for beautiful ladies."
Malaysians revere hibiscus as a national flower, each petal of the inflorescence symbolizes the commandment of Islam. The inhabitants of India and China respect this handsome man. Miraculous properties are attributed to this plant - the inhabitants of the East believe that hibiscus protects the hearth from evil intentions, helps business people succeed, and also gives strength to cope with depression.
Homeland and appearance of indoor hibiscus
The scientific name of the plant is Syrian hibiscus. The plant belongs to the Malvaceae family. Asia Minor is considered the birthplace of the Chinese rose, but the plant can be found in Korea, China and India.
This is a fairly tall shrub that, under favorable conditions, can grow up to three meters in height. The trunk is smooth, with gray bark. The crown is lush and voluminous, the leaves are large, have the shape of a shamrock.
At home, as a rule, only one type of plant is grown, which has large red inflorescences with five petals.
Watering mode
The most abundant and frequent watering is necessary for the plant during the period of active growth, especially in hot weather. Hibiscus does not store moisture, like some types of plants, which is why the lack of water is primarily reflected in its appearance: the leaves become sluggish at first, and then completely fall off. If you do not respond to these symptoms in a timely manner, the Chinese rose will die.
At the same time, excess moisture also negatively affects the health of the plant. If the soil is waterlogged for a long time, fungal diseases actively develop that affect the root system. In addition, water prevents the flow of oxygen to the roots, which also leads to their death.
Tip: the plant must be watered abundantly, but be sure to pour out excess water from the pan.
Watering is usually a morning procedure so that the Chinese rose has time to dry well by the evening. During the winter cold, hibiscus is dormant, so the frequency and amount of watering should be kept to a minimum. Also, experts advise avoiding abundant watering in the case when the plant is sick and actively sheds leaves.
Light requirements
Best of all, the plant develops on the southern windows. He is not afraid of direct sunlight. Moreover, if you want hibiscus to bloom, it needs direct sunlight for at least five hours a day. You can also grow a completely healthy strong bush on the southeast or southwest window.
If you choose a northern window for the Chinese rose, the plant may not bloom at all.
Note: Some varieties of Chinese rose tolerate light partial shade well. This applies to varieties with a brownish tinge of inflorescences.
Temperature regime
Hibiscus belongs to heat-loving plants, so the optimal temperature regime for it is considered to be from 24 to 30 degrees. Failure to follow these recommendations may result in the plant not blooming. From high temperatures, buds will fall off, and at low temperatures, buds will not form.
Tip: when choosing a pot for hibiscus, give preference to light colors to prevent overheating of the root system on hot days.
The minimum allowable air temperature for a plant is +7 degrees.
Air humidity
Humid climate for hibiscus - these are the conditions closest to natural, so it is necessary to maintain high humidity in the room all year round.
The plant tolerates air humidity up to 70%. To maintain such conditions, you can use a humidifier or a regular container of water.
In addition, hibiscus must be sprayed regularly.
Top dressing and fertilizers
During the period of active growth, the plant needs a significant amount of additional nutrients. However, conventional fertilizers for flowering plants can harm him. The fact is that for more active flowering, phosphorus-based fertilizers are used, in the case of the Chinese rose, phosphorus, on the contrary, poisons the entire bush and negatively affects the number of inflorescences and their quality.
Many flower growers note that the plant responds best to universal fertilizers, in which potassium and nitrogen predominate. In addition, hibiscus needs magnesium. With an insufficient amount of this component in the soil, the leaves on the plant begin to turn yellow.
- Feed only on cloudy days or late at night
- Water the plant thoroughly beforehand.
- Feeding frequency - once a week.
- With a decrease in growth rates, it is necessary to reduce the frequency of top dressing.
- Use foliar top dressing.
To do this, prepare a solution: take one part of the root fertilizer for ten parts of water, mix well. Spray the hibiscus leaves with the resulting solution either in the early morning or late in the evening.
Important: you can not feed the plant after transplantation and during the dormant period.
Indoor hibiscus transplant
Young plants need an annual transplant, with age it is enough to change the pot and the ground once every two or three years. Before you start transplanting hibiscus, you need to make sure that this procedure is necessary for him. The main sign that it is time to change the container and soil is a strong root system that has completely wrapped around an earthen clod.
Tip: so that after transplanting the roots can quickly germinate into new soil, it is necessary to water the plant in a pan.
A transplant is also necessary for a plant recently purchased from a flower shop. As a rule, poor-quality soil is used for transportation and maintenance, so experts advise not to hesitate and replace the soil as soon as possible.
Another reason to replace the pot and soil is the presence of stimulants in the soil. Manufacturers initially add substances that promote active flowering to the ground, as a result, plant growth slows down and there is a risk of infection with spider mites.
Propagation of indoor hibiscus
At home, you can use the propagation method of hibiscus cuttings. At the same time, flower growers use several methods of rooting cuttings.
- In mid-February, cut several cuttings from an adult bush and place them in wet sand. Cover the young shoots with a film and a jar. The plant must be kept under such conditions for two months at a temperature of 22 to 24 degrees.
- Cut cuttings can be put in water and wait until the roots appear. After planting a young plant in a pot with a substrate.
Note: there must be at least two internodes on the handle, otherwise the process will not take root.
The choice of flowerpot and soil
The diameter of the pot should be no more than nine centimeters. The earth mixture should consist of the following components:
- humus (two parts);
- leaf ground (one part);
- sod land (one part);
- sand (one part).
Hibiscus flowering time
Given that the tropics are the birthplace of hibiscus, it is able to bloom all year round, but this requires appropriate conditions - bright light, high temperature and humidity. As a rule, at home, the Chinese rose blooms for two to three months - from mid-summer to September.
The inflorescences are large - from 10 to 16 centimeters in diameter and look very exotic. The shape of the flower resembles a cup, while the inflorescence can be simple or double. In the center of the flower there are stamens, which are collected in a tube and pass into a pistil. Although hibiscus flowers are mostly odorless, very fragrant varieties can be found.
A new flower blooms at dawn and fades at sunset. On one branch, up to twenty inflorescences can form within one day, if the plant is large - up to fifty.
Pruning and shaping homemade hibiscus
During the period of active growth, the bush of the Chinese rose may acquire a sloppy appearance. To achieve a beautiful, "combed" shape of the bush, it is important to cut and shape it in time and correctly.
The procedure is carried out only in the fall, when the plant has already faded. This is due to the fact that buds can form on shoots that are older than three months. Thus, if you prune the plant in May, the new shoots will be too young and the hibiscus will not bloom.
Note: you can safely cut the Chinese rose, the plant easily tolerates the procedure and becomes thicker and more lush. Also, during the formation and pruning of the bush, it is necessary to completely remove damaged and infected branches and branches that are located parallel to the main trunk.
Tip: If you want your hibiscus to be attractive, form it into a stem tree.
Diseases and pests
In general, hibiscus is a fairly strong and hardy plant. Minor non-compliance with the growing conditions of the Chinese rose will easily survive. However, if you make mistakes regularly, the hibiscus may die as a result.
1. The main danger for hibiscus are:
- dry soil;
- drafts;
- low air humidity.
- regularly spray the bush;
- avoid drafts;
- protect from sudden changes in temperature.
2. Aphid. As a rule, the insect appears on young shoots and buds. If you do not provide timely assistance to the plant, the number of pests will quickly and dramatically increase.
Solution to the problem: treat the Chinese rose with a special chemical preparation.
3. Spider mite. It is not always possible to consider an insect, since it is very small. Lives under the leaves, hiding in a thin web. The reason for the appearance of the tick is dry air.
Solution to the problem: wash the hibiscus thoroughly with soapy water, spray the leaves regularly as a preventive measure and simply wash in the shower.
Frequently asked Questions
1. Why do hibiscus leaves turn yellow and fall off?
Often the cause is a disease such as chlorosis. It occurs due to an excess of chlorine and calcium in the water, which is used for irrigation. At the same time, there is an insufficient amount of nitrogen in the soil.
Solution to the problem: water for irrigation should be defended for several days and iron chelate should be added to it according to the instructions.
In addition, the cause may be a disease of the root system or too dry air in the room.
2. Why does indoor hibiscus not bloom?
Here are a few rules, the observance of which will achieve abundant flowering.
- During the budding period (February-March), the air temperature should not be higher than +15 degrees.
- At this time, reduce watering.
- Remove the plant from bright sun.
Such conditions are typical for office premises, so you can often observe how hibiscus bloom brightly and profusely in offices. If you manage to comply with the above conditions at home, hibiscus will surely please you with flowers.

More information
Hibiscus, otherwise known as Chinese rose, is a popular ornamental plant with beautiful bright flowers. At the moment, many varieties have been bred that take root well at home and grow well. Hibiscus, indoor care at home which is carried out in accordance with all the rules, will delight the owners of the house with its flowering for a long time. So, what should be the care of indoor hibiscus at home?
Who first decided to call the Chinese rose that way is not known for certain. Since ancient times, there have been various signs relating to plants. Some superstitions promise good luck, others are not so optimistic. So why is hibiscus called the flower of death? However, this is not the only plant that has fallen into such an unfortunate list, except for the Chinese rose, ivy, calla are considered deadly, and according to popular beliefs, all these plants bring death to the house.
Hibiscus has different meanings. If the plant suddenly blooms, this is a sign of the imminent death of one of the household members. Dropping leaves promises serious illness and trouble. Probably, once such coincidences really happened, because of which the flower gained notoriety. However, in Soviet and current years, this is a very popular plant in city apartments, behind which no ominous manifestations have been noticed.
Can you keep hibiscus at home? Absolutely yes. Flowers, leaves and fruits of hibiscus are not poisonous, which means that superstitions have no convincing basis.
Optimal temperature
How to care for hibiscus? The Chinese rose loves warmth, so for its comfortable existence it is necessary to maintain a temperature not lower than 18 and not higher than 22 degrees Celsius. However, hibiscus blooms in a cool period at + 15º C. Therefore, after the summer months, it is better to take the flower to a cooler place without bright sunlight. In summer, a pot with a plant can be kept on a veranda in the garden or on the balcony of a city apartment. Chinese rose loves fresh air, but it should be protected from drafts.
What lighting to choose
Hibiscus loves not only warmth, but also the bright sun. For this reason, it should be kept in the southern rooms. If it is too hot, the plant should be removed from the windowsill away from the glass or covered to protect it from the sun. Alternatively, the flowers can be placed on a table near the window, where there is enough light, but the sun's rays are no longer so aggressive and will not damage the delicate hibiscus petals.
The lack of light is one of the reasons why hibiscus leaves turn yellow and fall off, and in some cases buds. What to do in such a situation? It is enough to provide the plant with access to good lighting.
How to water
Hibiscus requires timely watering, apart from constant spraying. Without enough moisture, it can dry out. You need to water the flower with water only at room temperature; before watering, the water should settle in a glass container with a wide neck. If the apartment is too hot, moisture will quickly evaporate from the ground. To prevent this from happening, you need to use devices to reduce evaporation or cover the ground with ordinary moss.
In order for the leaves to be green and healthy, they need to be sprayed regularly and the air in the room must be kept sufficiently humid. To do this, you can use humidifiers or simply put water containers on the batteries. When spraying the leaves, you can not touch the flowers, they must remain dry. Periodically, the plant needs to be washed in the bathroom, washing away dust and dirt from the leaves. To prevent water from leaking into the pot, cover it with a plastic bag.
If the leaves turn black, this is a sign of excess water. To save the plant, it must be taken out of the pot along with an earthen clod and put to dry for 12 hours. Then it is worth cutting off the rotten roots and transplanting the flower into fresh soil.
Difficulties in Growing Hibiscus
Hibiscus is a fairly unpretentious plant, so even if you make a mistake somewhere when leaving, it can be quickly corrected. Those who have only recently acquired a Chinese rose often wonder why the leaves of the hibiscus turn yellow, begin to dry out or fall off. This problem is easily corrected by spraying more frequently once you notice that the leaves have become limp. In addition, the plant itself sheds leaves after flowering - this is completely normal. 
If the flower is withered, this may be a sign of too cold ground. From hypothermia, the leaves may also turn black. The plant must be returned to a warm place and do not forget about abundant watering. If everything is done in time, hibiscus can still be reanimated.
Why do hibiscus leaves turn yellow and fall off? Such a problem may indicate poorly filtered water. If the leaves are not only yellow, but also with brown edges, this means that there is little nitrogen in the ground. When temperatures and humidity fluctuate dramatically, a stressed plant sheds both leaves and buds. However, then it is restored and grows new leaves.
How to plant Angel Wings
Pests and diseases
Hibiscus Chinese, like any other indoor plant, is faced with various diseases and pests. If the care of hibiscus at home is timely, it helps to avoid trouble. However, even with good care, mites, aphids or some diseases can appear, which can be a headache for beginner growers.
Spider mites
All dry flowers and leaves must be removed in time. If preventive measures were unsuccessful, in order to get rid of the tick, more frequent watering and spraying is needed. In this case, the pot of the plant must be completely covered with polyethylene so that the moisture does not evaporate. Spider mites die in too humid conditions.
Aphid
In a small amount, aphids are not dangerous, but if there is too much of it, the leaves will begin to turn yellow, curl up into a tube and fall off sooner or later. The plant itself will be sluggish in appearance and stop blooming. If there are too many aphids, sticky secretions of these insects will be visible on the leaves.
While there are few aphids, the leaves can simply be washed with soapy water. If the insects have already settled down on the Chinese rose, only spraying with special means will help here. After using chemicals, the plant will need more thorough care until it is fully restored.
leaf chlorosis
This disease is typical for hibiscus. Chlorosis occurs due to improper care of the flower. Signs of the disease:
- change in the shape of the leaves;
- the appearance of brown spots;
- dry petals;
- buds do not bloom and fall off.
Chlorosis indicates deficiencies in useful trace elements - manganese, potassium, zinc, etc. The plant can be saved by transplanting it into fresh and well-fertilized soil. In addition, daily spraying is necessary. If the disease has begun recently, it is enough just to fertilize the soil.
Indoor hibiscus is not capricious in care, and therefore both experienced growers and beginners can grow beautiful flowers. Large bright flowers will decorate the room and will please the eye for a long time. Such a flower can become not only an interior decoration, but also a good gift for relatives or friends.
The desire to follow fashion and turn houses into flower greenhouses is good. Not everyone succeeds in growing such indoor specimens of flowers that surprise with their lush flowering and appearance. Why is this happening?
Because before buying a flower, you need to learn about all the features of its growth. Without top dressing, lighting and care, not a single plant will have a presentable appearance and will simply wither in a dark corner.
Hibiscus or Chinese rose is bought and wanted to grow because of its large lush flowers of bright red color.
Flowers can be not only red, but also yellow, crimson, white. Flowers are distinguished by shape - there are simple, there are lush, medium and large. The flower itself is large and requires a lot of space, unlike its counterparts that live on the windowsill.
With the right care, hibiscus can grow to 3 meters high and it will be necessary to transfer it to the greenhouse. If there is none, then you will have to immediately take care that the tree grows in width, and not in height. The rules of care include pruning and shaping the bush.
Important! In order for the Chinese rose to bloom and have a lot of flowers, you need to follow all the rules for caring for the plant
soil for hibiscus
The root system of a large plant needs a constant supply of oxygen. If the soil is heavy, it will make it difficult for the tree to aerate and absorb nutrients.
For good growth and future flowering, it is better to mix the soil yourself. To do this, you need to prepare one part:
- sand;
- peat;
- sod land;
- ordinary garden soil;
- rotted leaves.
You can add charcoal. To feed the hibiscus, you need to mix wood ash into the soil - 2 cups of ash per 10 kg of soil. Ash also contributes to the loosening and influx of the soil, and at first there will be something to feed indoor hibiscus so that it blooms after rooting.
Drainage is placed at the bottom of a spacious pot - stones, pebbles, shells, expanded clay. Chinese rose does not tolerate stagnant water in a pot. You may need to change your watering method and add water to the pan to dry the soil.
Chinese rose lighting
Hibiscus is a photophilous plant. Putting it in a dark corner of the room and expecting it to bloom is not worth it. In case of violation of the process of photosynthesis, which occurs only in the presence of sunlight, the absorption of nutrients responsible for the appearance of buds is disrupted - these are phosphorus and potassium. Therefore, you need to look for a place such that the influx of light is constant.
It can be a balcony loggia or a place under the window. If the plant is small, it will fit on the windowsill.
In the spring, the hibiscus is taken outside to ventilate and get used to the sun's rays. First you need to shade the leaves to avoid burns. Once you get used to it, open it completely.
pruning hibiscus
In order for the Chinese rose to bloom, you need to prune. Branches growing inward interfere with light and make growth difficult. So they are cut off. The tops also need to be pinched.
Flowers are formed on young shoots, so it is important that there are more of them. Old branches can be cut to 1/3 of the length. The tips of the shoots after flowering are cut off so that young side shoots are formed, on which buds will in turn appear. Thus, with pruning alone, hibiscus blooms can be formed.
Pruning is carried out in late winter or early spring. Although, year-round regular crown pruning does not harm the Chinese rose.
If indoor hibiscus grows well and the upper branches are already touching the ceiling, they need to be removed. By trimming the top branches, the growth of the side branches is stimulated. For the growth of green mass, the plant needs nutrients. How to feed a Chinese rose at home?
Chinese Rose Fertilizers
Fertilizers for indoor hibiscus can be made independently from improvised means - tea leaves, eggshells, banana skins. But it is better to use proven methods - buy and use more nutritious products - mullein, chicken manure, mineral mixtures.
organic matter
From organics for feeding hibiscus fit:
- mullein infusion;
- infusion of chicken manure;
- wood ash;
- bone flour;
- green manure;
- humus;
- compost.
In order not to burn the hibiscus root system, it is recommended to use manure and chicken manure in the form of a diluted infusion. It is necessary to carry out activities such as insisting on manure at their summer cottage. The smell in the apartment can become unbearable.
To prepare the infusion:
- fill bucket manure or chicken manure by a third;
- to fill with water;
- insist 3 – 4 days, stirring to evaporate excess ammonia;
- liter of infusion from mullein dilute 10 liters of water , liter of chicken infusion - 20 l.
Green manure is done as follows:
- Fill a third of the container with grass;
- to fill with water;
- insist 3 - 4 days.
Water under the root. Infusions of mullein, dung and grass contain nitrogen and potassium. But for phosphorus nutrition, you will have to use other substances of animal or vegetable origin. It is bone meal or wood ash.
Hibiscus ash is used dry or poured with infusion - 300 g of ash per bucket of water. The ash solution is a source of potassium and phosphorus for roots and flowering. Ash has one drawback - a low nitrogen content, since during combustion it escapes into the atmosphere. Nitrogen supplements can be applied foliarly. Dissolve 1 g of urea in a liter of water and spray with a spray bottle.
Important! At the same time, nitrogen mixtures and ash cannot be introduced into the soil. These substances neutralize each other's action and become useless for rose nutrition.
Bone meal has an advantage over other organic fertilizers - it costs less, is applied less often, and works longer. The substance is rich in calcium, potassium and especially phosphorus. During the season, you can use it once, since the fertilizer completely decomposes in the soil in six months. For 10 kg of soil mixture, you need to lay 2 cups of bone meal.
Mineral mixtures
Mineral fertilizer for indoor hibiscus should contain potassium and phosphorus. Some flower growers do not recommend using nitrogen fertilizers, explaining that hibiscus does not like them. But in order for the plant to grow and keep green, nitrogen is necessary. No need to overuse.
Video: Top dressing for the rapid growth and flowering of Chinese roses
If the plant asks for supplements, and this can be seen from the leaves - they become pale and lethargic, then you can spray it with a solution of urea or pour it over with a complex mineral mixture. Watch for a couple of days. If the foliage comes to life, then the plant needs nitrogen and you can re-spray.
Hibiscus need potassium and phosphorus to bloom. Potassium is responsible for the formation of buds. Phosphorus - for root growth. If the roots are not mature, the flower will drop the bud. This sometimes happens with small indoor Chinese roses that have been grown from cuttings. The hibiscus does not yet have enough strength to support flowering, so it refuses to bloom.
Diseases of the Chinese rose
Hibiscus, like other plants, is susceptible to diseases:
- bacterial;
- fungal;
- from a lack of trace elements;
- sunburn;
- tracheomycosis (fusarium).
The fungus is manifested by twisting the foliage, falling greenery. The reason is the reproduction of the fungus in the soil with insufficient disinfection. The spores are carried by the wind if the plant is outdoors in the summer. Contribute to fungal infection imbalance of nutrients.
Fusarium is a very dangerous disease for hibiscus. Usually ends in death if the affected roots are not noticed and removed in time. The main cause of the disease is excessive watering, in which the root system rots. The spores of the fungus in the soil penetrate into the tissues. It is unlikely that such a plant will be saved.
Hibiscus (Syrian rose) is a perennial flowering shrub. Leaves petiolate, incised. In most species, the flowers are quite large, graceful, with bright corollas, outwardly similar to mallow flowers.
For a more fruitful flowering of hibiscus, the flower needs a large amount of sunlight.
The hibiscus bush lives for over 20 years. In addition, this plant lends itself well to molding: to increase the branching, at the end of winter, you need to cut the stems of the plant.
In nature, there are about 200 varieties of hibiscus, but almost all of these plants are tropical, and in our climate, most simply will not survive. So, the Syrian hibiscus grows successfully in a temperate climate. Of course, only if the flower is sheltered for the winter (in the likeness of roses). If the flower is planted in areas with not very severe winters, then you can give a 100% guarantee that it will quickly take root and delight with magnificent flowering every summer.
Garden hibiscus: location
To prevent aphids from starting in the hibiscus, you can plant lavender nearby, but only if climatic conditions allow.
The most important condition for growing Syrian garden roses is a lot of sunlight. Only under normal lighting can a good flowering of hibiscus be achieved. In order not to choose a place, you can simply plant it among roses: these plants blend very well with each other. Usually varieties of Syrian hibiscus are compact and undersized (1-1.5 m), so it fits well into any rose garden. But as a separate plant, it is also very good.
If the climate allows, then you need to plant lavender bushes nearby. This neighborhood is not only beautiful, but also useful: the aroma of lavender can drive away the worst enemy of all hibiscus and roses - aphids. It should be noted that non-double varieties of hibiscus are more frost-resistant than terry ones, so this fact must be taken into account when choosing a plant.
To protect the hibiscus from aphids, it can also be sprayed with water and ordinary cigarette ash.
To do this, you need to take an ashtray with cigarette butts, fill it with water and leave for 2-3 minutes, then strain and treat the plant with the resulting water. Such water will not harm the hibiscus, and the aphids simply cannot stand it.
The soil for garden hibiscus should be permeable and fertile enough. Otherwise, the hibiscus simply won't produce color.

Feeding and watering garden hibiscus
For hibiscus, it is best to use fertilizers that contain phosphorus.
This flower does not need intensive watering, it should be watered moderately, as the soil dries out. But keep in mind that in most regions the temperature in summer is almost tropical, so watering can even be a daily procedure. In order for the Syrian rose to bloom profusely (blooming lasts from the beginning of summer until the autumn cold), it is advisable to feed it with phosphorus-containing fertilizers from time to time (about once every 2 weeks). In order for the plant to endure the winter more easily, at the beginning of autumn you need to feed it a couple of times with fertilizer with potassium.

Reproduction and planting of a garden Syrian rose
For breeding and planting hibiscus you will need:
- hibiscus seeds or cuttings;
- fertile soil;
- peat;
- glass bowl (jar);
- pot for rooting a flower.
Of course, the flower is planted in the spring. Seeds should be sown from January to March. Before planting, the seeds are soaked in epin for 12 hours, and then sown in a mixture of sand and peat. The bowl must be covered with glass, and it must be kept at a temperature not lower than + 25 ° C and not higher than + 27 ° C. The use of bottom heating or a mini-greenhouse contributes to good seed germination. Periodically, the earth needs to be sprayed, and the bowl should be ventilated. When the seedlings have a few leaves, they need to dive into small pots. Seedlings will begin to bear fruit in 3-4 years.
Hibiscus is easy to propagate using cuttings that need to be cut in June-August with 2-3 internodes from the tops of the young growth. Sections must be treated with growth stimulants. Cuttings usually take root in about 1 month in indoor greenhouses with soil heated to + 25 ° C (pure sand or a mixture of peat and sand), or in pots that are covered with a glass bowl, or in ordinary water. If the stalk has taken root in the water, then after they appear, the plant is planted in 10-centimeter pots with soil, everything is watered with warm water.
The soil for planting can be taken directly in the garden, but it will need to be rubbed with peat. A rooted cutting can be planted directly into the ground, but at the same time, the warming of the flower must be appropriate.

Pruning a Syrian rose
Garden hibiscus forms flower buds immediately on young shoots. Therefore, the more such shoots there are, the more flowers will appear. Their growth is facilitated by pruning the plant. Often there are recommendations that garden hibiscus should be cut every 3-4 years. But this statement is not true. The plant tolerates pruning very well and nothing terrible can happen from it, except for good. It is best to prune hibiscus every year at the end of winter, before the plant begins to actively grow. In addition to the fact that pruning perfectly stimulates the growth of shoots, it can be used to give the bush a more decorative look. In the south, where garden hibiscus can be found absolutely everywhere, you can see flowering balls, pyramids, cubes that adorn the flowers of this plant. Due to this feature and compactness of the plant, it can be grown not only in the country or flower garden. Syrian hibiscus, if desired, can be planted on the terrace or in a pot on the balcony.
Rosa chinensis (hibiscus) is an evergreen shrub whose leaves are oval, smooth, oblong, with serrated edges. The plant grows successfully both in greenhouse conditions and at home in pots.
In order for the flower to actively bloom and delight the owners with its presence, it needs to provide full and proper care. It consists in:
- landing in the ground;
- irrigation organization;
- ensuring optimal light and temperature conditions;
- pruning (the procedure allows you to control the height of the bush, makes it possible to develop side shoots)
For the normal growth and development of hibiscus in the soil in which it grows, mineral and organic top dressing should be applied in a timely manner.
soil for hibiscus
In order for the plant to grow well, it is necessary to ensure a full flow of oxygen to its roots. To this end, hibiscus is planted in the ground, which is a fertile mixture of sand, peat, turf, garden soil, rotted foliage. It is also useful to add charcoal or ash to it (the consumption of the latter will be 2 cups for every 10 kg of land). For an indoor flower, it is imperative to use drainage (they cover the bottom of the pot).
Landing and transplant
The Chinese rose loves lighted places, so it is planted in those areas where a sufficient amount of sunlight enters throughout the day. Initially, young leaves are shaded a little to allow them to adapt without getting burned, and then fully opened. Home plants are planted in pots with a height of 7 to 10 centimeters.
Hibiscus are rarely transplanted - once a year or for five to six years. Do this in the case when the roots do not have enough space. Move the rose to a new container a little larger than the previous one by transshipment (leave the earth lump intact). The most favorable time for the procedure is winter or summer. You can transplant in the spring - after the bud has faded. It is not recommended to carry out the manipulation in the fall: during this period, the plant is at rest.
Watering, lighting, temperature control
Chinese rose prefers moderately moist soil. Maintaining sufficient soil moisture is especially necessary in the spring and summer, when active flowering is observed. Do not allow an excess of moisture or excessive drying of the soil throughout the season, otherwise the flower may die.
Water used for irrigation should first be filtered or allowed to settle. Flower growers advise her to spray foliage several times a week. This will help maintain a comfortable humidity level.
In order for indoor hibiscus to bloom well, it must be kept on those windows where there is no lack of lighting and where the sun's rays penetrate well throughout the day.
The optimum temperature regime for roses is up to 22 ° C in summer and up to 15 in winter.
Proper feeding of Chinese roses
Periodically feed hibiscus in the same way as other plants. This allows you to maintain the desired level of mineral and organic trace elements necessary for normal growth and flowering of the crop, and prevent their deficiency.
The lack of nutrients in a plant is indicated by:
- leaf deformation (thinning, drying), change in their color;
- delay or complete cessation of growth;
- shortening the flowering period;
- reduction in flower size;
- weakening of the root system and its ability to absorb useful components;
- suspension of the formation of buds and side shoots.
- susceptibility to frequent illnesses.
Fertilizers for hibiscus should be applied twice in the spring-summer period (from April to September) and only once - in the autumn-winter period (from October to March). Before fertilizing hibiscus, the soil under it must be well moistened and allowed to absorb moisture.
organic matter
Of the organic fertilizers, the following are popular with flower growers:
- Manure. On its basis, a nutrient solution is prepared: one tablespoon of the product is diluted per liter of water. The main ingredient is used in dried form. This fertilizer is suitable for annual plants.
- Mullein: the third part of the bucket is filled with water, insisted for three days, then diluted with ten liters of liquid.
- Grass. The solution is prepared in a manner similar to the previous one.
- Ash. Sprinkle dry matter on top of the earth. You can prepare a liquid composition for irrigation by diluting 300 g of the natural component in a bucket of water.
- Bone flour. Contains a balanced amount of phosphorus, nitrogen and potassium. To fertilize 10 kg of land, 2 cups of dry matter are required.
Mineral mixtures
For the full growth of hibiscus at home, it needs minerals. The main ones are:
- Nitrogen: affects plant growth, determines the intensity and degree of development of its root system.
- Potassium: provides metabolism, participates in photosynthesis, in the formation and accumulation of organic matter in plant cells. Responsible for the formation of buds.
- Phosphorus: activates the formation of the root system and the flow of all the most important processes, provides stress resistance and the ability to withstand temperature drops.
The following are used as the main mineral fertilizers for Chinese rose:
- Urea. For dilution, 1 gram of the product per liter of liquid is required. Fertilizer is applied by leaf method.
- Kalimagnesia is a mixture containing potassium and magnesium. Prevents falling leaves, their deformation, pathological discoloration.
In order for the Chinese rose to develop well and bloom quickly, you can purchase in the store and effectively use ready-made fertilizer complexes. Among those:
- "Ideal";
- "Kemira Lux" (or "Universal");
- top dressing for roses in the granular form "Fertika";
- "Athlete";
- "Gilea";
- "Master".
- Fertomix.
Good nutrition allows you to extend the flowering period, increases the resistance of the flower to diseases and pest attacks (fungal infection, aphids, spider mites).
Home cooking supplies
You can make your own hibiscus fertilizer at home. Amateur flower growers know their secret of how to feed indoor hibiscus so that it blooms luxuriantly. For this purpose, it is recommended to use:
- Sugar. It can be poured into the soil from above or you can prepare a solution: dissolve a teaspoon of raw materials in a glass of water and water the plant with liquid 2 times a month every fourteen days.
- Glucose. It is required to dissolve 1 tablet in a liter of liquid.
- Water in which meat was thawed or cereals were washed.
- Coffee grounds (it is mixed with the ground).
- Tea brew. The method of application is similar to the previous one. Such fertilizer should be applied in moderation so as not to provoke the appearance of midges and acidification of the soil.
- within two weeks after planting the flower in a new soil;
- while the plant is in a draft;
- in the hot season in the middle of the day;
- with a sharp rise in temperature.
Hibiscus is undemanding to environmental conditions, unpretentious to care. It can successfully grow and bloom for a very long time if it is fertilized in the right way. A timely and properly fed plant will become a real decoration of the house and will delight the owners with its presence throughout the spring-summer season.
