During its dormant period, hibiscus should receive enough light and moisture: should ensure good level lighting and moderate watering. It should be minimally disturbed at this time so that the plant can rest, gain strength and prepare for flowering.

The laying of new buds in the Chinese rose occurs at a temperature not higher than + 15 ° C. In February, hibiscus is placed closer to warmth and light, and the number of fertilizing and watering is gradually increased.

You can also send a rose for the winter by first completing it. To do this, in the fall you need to give him the opportunity to shed his leaves. To this end, watering is gradually reduced to a minimum. When the leaves of the hibiscus fall off, the stems are carefully cut, leaving “stumps” 6-8 cm long.

During this time, all insect pests and their larvae, bacteria, fungi, and viruses die in the soil. The disadvantage of calcining the earth is that it is destroyed and beneficial flora. However, it is easy to restore. It is enough to leave the soil alone for 2 weeks and water it once every 4-5 days.

Before transplanting hibiscus, large gravel, polystyrene, broken bricks are laid on the bottom of the flowerpot for good drainage of the soil. The plant is transferred to a new planting site as carefully as possible, trying not to damage the roots. It is better to keep an earthen ball around them.

blooming hibiscus

In order for the hibiscus to bloom, after dropping the leaves and before being sent for wintering, pruning is carried out. The stems are removed, leaving stumps no higher than 10 cm.

The dormant period for hibiscus growing at home lasts from late October to early February. At this time, he is transferred to a room with a temperature of 15-16 degrees. Watering at this time should be moderate, fertilizing is canceled altogether. As for lighting - during the rest daylight hours should last 9-11 hours. In a dark room, hibiscus can be additionally highlighted with a phytolamp.

By the end of the rest, it forms a large number of flower buds, which will eventually turn into beautiful flowers. After a dormant period, the plant is returned to a warm and bright room, more frequent and plentiful watering is carried out, and top dressing is done. And hibiscus begins to bloom from early summer to late autumn.

If the hibiscus was not pruned before the dormant period, this procedure can be carried out after it. After spring pruning, the plant is fed with nitrogenous, and then potassium-phosphorus fertilizers every 10 days.

Hibiscus buds form on young branches that have grown in the current year, and they appear precisely after pruning. If pruning is not carried out, it will be difficult to get the hibiscus to bloom. It is impossible to prune the shoots in the summer - in this case there will be no flowers either.

Another reason why hibiscus does not bloom at home is that the pot is too spacious. To wait for the flowers, you should not transplant the plant into a container large sizes, in it the roots will feel freedom, and will begin to actively grow, all the power of the bush will be spent on this process, and not on flowering.

It is better to put a flower pot in a warm and well-lit place, but not necessarily under the direct rays of the sun. Hibiscus prefers diffused light, in warm time year, it can be taken out to the street or to the balcony, but sheltered from the strong rays of the sun.

The plant loves moisture, so in the summer it is watered twice a day - in the morning and in the evening, the soil in the pot should always be wet. For irrigation, it is better to use warm, soft water, tap, chlorinated water can kill the flower. The flower is sprayed only in summer, no more than 1-2 times a week, this procedure not only increases the humidity of the air, but also prevents the appearance of spider mites.

What kind of soil is needed for planting hibiscus? The soil mixture for planting it is made at home from turf and leafy soil, humus and peat. To make the soil light, sand and charcoal are added to it.

The acidity of the soil for hibiscus must be neutral or high, otherwise it may weaken due to the inability to receive enough nutrients.

According to the reviews of flower growers, the shrub is undemanding to its owner. Simple terms maintenance and minimal care is necessary for a culture to normal growth and development. But many lovers indoor plants complain about the lack of long-awaited buds. If the hibiscus does not bloom, mistakes were made during cultivation. Both a lack and an excess of attention for a flower can affect its vegetative processes.

Reasons for the lack of flowering

When growing Chinese roses, many flower growers harm the plant with excessive care and improper care. The reason for the lack of flowers on hibiscus can be the following factors:

  • excessive feeding or unsuitable soil;
  • prolonged contact with the sun or its absence;
  • poor or too intense watering;
  • unsuitable room temperature;
  • cramped or very large pot;
  • unnecessary care during the winter dormancy.

Proper care of indoor hibiscus

In order for indoor hibiscus to bloom at home, specialist skills are not needed. The main thing is to properly care for the plant and provide it with the necessary conditions for the formation of flower buds.

Planting capacity and soil

A shrub planted in a pot that is too large will grow well, grow a green lush crown and not bloom. In order for the hibiscus to begin to form buds, its root system needs to fill the entire container. For a young plant, choose a compact tub that matches its size, and change it as needed to a larger one.

The substrate plays very important role planting hibiscus. The seedling will need fertile soil with a neutral pH level from soddy and deciduous soil with the addition of humus and sand. A layer of pebbles or expanded clay is laid at the bottom of the container, and a prepared earth mixture is placed on it. Periodically, the top layer of soil is removed from the pot and replaced with compost.

Temperature and watering

In winter, when the dormant period begins, flower buds form at the hibiscus. At this time, it is important to create right conditions contents for a flower. In autumn, when nature falls asleep, the Chinese rose is removed to a cool place where the temperature ranges from +12 to +15 degrees. The plant is forgotten until the last winter month. Do not allow sudden changes in temperature in the room.

In order not to harm the Chinese rosan during watering, the following rules are taken into account:

  1. 1. For irrigation, rain or settled soft water is prepared without the addition of chlorine.
  2. 2. When the air temperature in the room where the flower is located drops below +15 degrees, watering is minimized.
  3. 3. In warm weather, the top layer of the earth should not dry out completely.
  4. 4. Hot summer days the plant is abundantly watered under the root and the leafy crown is sprayed with water.

Balanced fertilization

From a lack of top dressing, indoor hibiscus discards unopened buds, and from an overabundance, it does not form at all. Fertilizers are applied seasonally, moderately, taking into account the vitamins and chemical elements necessary for flowering.

"Asian" feed the entire growing season every 7-10 days. To make the shrub bloom, use complex fertilizers for ornamental flowering plants containing potassium and phosphorus, which will accelerate the growth of the root system and help the formation of flowers. Nitrogen fertilizers are used less often - when the leaves lose their healthy appearance. From organic matter, fermented bird or cow manure diluted with water 1:10, compost, tree ash is used. Top dressing is applied only after watering in the morning or evening. In winter, fertilize no more than 1 time per month.

pruning

The laying of flower buds occurs only on young shoots. In order for more buds to form on the Chinese rose, cut off the old branches and pinch the tops of the shoots.

Pruning is carried out in late February or early March, when the shrub reaches two years of age. They also cut off dry, damaged and inward-growing branches. This procedure will improve the decorativeness of the crown and accelerate the growth of the plant.

Suitable place in the house

Ornamental shrubs cannot be moved from one place to another. It should be in a cool (+18–22 degrees), ventilated room with diffused daylight. In the shade, the plant will not die, but it will not bloom either, and prolonged "sunbathing" is even more harmful to this representative of the flora. Drafts and wind negatively affect the flower.

Stamp house tree

Chinese rose can be grown in the form of a trunk. With the help of special manipulations, the bush will take on the appearance of an original tree with a rounded crown and an even vertical trunk.

At home, the procedure is as follows:

  1. 1. Choose a young indoor hibiscus bush with an even central stem. A stable support is attached parallel to the trunk, tying it at the same distance along the entire length of the shoot. Lateral branches are pruned as they appear.
  2. 2. The top of the tree is pinched when it grows to the desired size.
  3. 3. After pinching, the growth points form a crown, monthly cutting the shoots and their tips.

Over time, the crown will become spherical. An ornamental tree will require proper care. In the fall, pruning is carried out to maintain a beautiful standard shape.

Chinese rose (Hibiscus) is a tall ornamental crop. Differs in large flowers of various flowers and their shades. Possible colors: red, orange, white, purple. Numerous cultivars have been bred with countless flower shades up to black.

  • Wrong temperature in winter. Optimum temperature hibiscus content in winter should be about 15 degrees, but no more;
  • Regular pruning and pinching. More precisely, their absence Since flowers are formed only at the tops of young branches, the branches need to be cut and pinched to form a compact, dense bush;
  • Excessive hydration soil during the growing season;
  • Lack of light. Hibiscus prefers bright diffused light, but direct rays are fraught with burns;
  • Excess nitrogen in the soil. It is required to limit the application of nitrogen fertilizers.

What to do to make hibiscus bloom luxuriantly and plentifully?

In order for the Chinese rose to please with its lush flowering every year, it is necessary to observe the features of the content of the culture:

  1. The location in the apartment is a southern or eastern window with shading during the midday sun. In the shade the flower will not bloom;
  2. Proper wintering. The temperature in winter should not exceed 15 degrees. If the temperature is less than 10, then the plant will drop foliage;
  3. Pot and soil. The pot should be a little cramped for the root system, only then the culture will please with flowering; The pot needs good drainage. The acidity of the soil should be neutral. Clay turf is required in the composition;
  4. Pruning must be systematic, otherwise the bush will grow strongly, but will not bloom;
  5. Water for irrigation should be soft without chlorine and scale. The temperature is about 30 degrees Celsius. In summer, you need to water abundantly and regularly, and in winter - less often. However, overflows are dangerous for the plant;
  6. The introduction of fertilizers. For flowering, fertilizers with a high content of phosphorus are considered extremely effective;
  7. No temperature fluctuations or drafts.

Thus, in order for the Chinese rose to bloom, it is necessary to observe the peculiarities of care, to feed the culture only in the summer-spring season. It is recommended to choose fertilizers with a high content of phosphorus. This promotes lush flowering. However, an excess of fertilizing, on the contrary, can harm the plant. During the dormant period - in winter - it is not necessary to feed the culture.

For irrigation, you need to take soft and settled water. Hibiscus does not tolerate water with scale and chlorine. Therefore, before watering the culture, it is required to defend the water for several days. You can also filter or boil the water.

Important! During the formation of buds, you can not turn the pot and change its location.

  • Non-infectious and infectious chlorosis. The reasons are: excess nitrogen in the soil, fungus;
  • Fungal infections lead to bud drop;
  • Root rot can lead not only to the absence of flowering, but also to the death of the plant.

Chlorosis (lack of iron) on leaves. Solutions - transplants, top dressing, time for rehabilitation.

A flooded plant affected by root rot.

infectious fungal diseases treated with fungicides.

Among the pests should be highlighted:

These pests usually infect leaves and stems, they practically do not affect flowering. However, huge accumulations without treatment can lead to the death of the culture. These pests are treated by wiping the plant with soapy water and insecticidal preparations.
