Now there are several hundred forms and varieties of hibiscus grown in ornamental horticulture and indoor floriculture. It is famous for its charming flowers of very different colors, they are simple and terry and appear on the plant for several months.
In room culture has long been common hibiscus chinese (Hibiscus rosa-sinensis) with dark green shiny leaves and gorgeous red double flowers, for which he was nicknamed Rosan Chinese. It grows quickly and, with good care, easily turns into a large, sprawling tree. About him and talk.
Conditions of detention
Chinese hibiscus is quite unpretentious and shade-tolerant, but it is preferable to keep it in light enough room, avoiding direct sunlight. This is one of the conditions for good flowering. In the summer it is useful to expose the plant to fresh air in a bright place protected from the wind. The optimum temperature content in the range of 18−22 ° C.
The period of flowering of Chinese hibiscus usually occurs in the spring, summer and autumn: its crown is periodically decorated with magnificent single double flowers. Watering at this time should be regular and abundant after drying the top layer of soil. Land after irrigation must be loosened to ensure air access to the roots. Strong overdrying of soil during this period is unacceptable.otherwise the plant will drop foliage and buds. In winter, watering is reduced.
Hibiscus is very responsive to fertilizationIn the spring-summer period, an adult plant is fed about 3 times a month with mineral fertilizers or a weak solution of organic matter. In winter, feed a weak solution of fertilizers 1 time per month.
Useful daily sprayingespecially in winter when kept in a warm heated room with dry air.
And now - attention! Very often there are complaints by flower growers that, they say, I cherish my rose - and I hold it in the sun, and water it regularly, and feed it, but it does not bloom - even crack! And if you look at any store or institution, you’ll see a forgotten tree in a tub in a half-dark hall, nobody cares for it, water as much as necessary, but it blooms without ceasing. Familiar picture, right?
And the thing is that the temperature of the air around 15 ° C contributes to the setting of the flower buds in Chinese rosewood. At this temperature, the soil dries out slowly, therefore, it should be watered very rarely. And this - the main secret of getting luxurious flowers. As a rule, such conditions in the above-mentioned state institutions are formed in the autumn, when the heating season has not yet begun, and the cooling is already noticeable. At this time, the room is very cool and hibiscus falls into a state of rest, actively laying the beginnings of flower buds, which are activated with the arrival of spring.
Please note that in the apartments with central heating there are similar conditions in the autumn, and you just need to use them in order not to interfere with the plant to rest properly. And with the inclusion of heating, you only need to place your hibiscus in the coolest place of the apartment (even in low-lit) and not disturb the end of winter with unnecessary watering.
Awakening occurs around February, as can be seen from the beginning growth of young leaves. Then the plant is rearranged to a bright warm place and begin to be watered and fed. If the moment of awakening is missed and you will rearrange the hibiscus already with buds, then be prepared for the fact that with a sharp change in the microclimate, it can discard the first buds and even partially the foliage. Then, of course, he will catch up, but it is better not to make him such an extreme.
Planting and breeding
To grow hibiscus, a loose and very nutritious soil mixture consisting of about 2 parts of sod, 1 part of leaf and 1 part of humus soil is needed, you can add a little peat and sand. At the bottom of the pot must be laid drainage.
Young plants grow very quickly, so they may need to transplant into a larger pot more than once a year. In the future, each year in early spring they need to be transplanted into fresh fertile soil. Adult plants are rarely transplanted, but each spring they replace the top layer of soil in the pot with a fresh, more nutritious.
At the end of winter, it is useful to prune an adult plant, which stimulates abundant branching and flowering. The branches are cut to two-thirds or half. The resulting cuttings serve as material for reproduction. They quickly release the roots in water or when placed in a greenhouse in a loose substrate. For breeding, you can cut the tops of young shoots not only in spring, but in summer, better in August. Young plants with good care bloom after a few months.
On hibiscus, buds appear, but do not open and soon fall - the plant lacks nutrients; watering is not abundant, the soil dries out strongly; low air temperature.
The lack of flowers in the presence of lush numerous foliage - the plant is overfed with fertilizers with a high nitrogen content; lack of lighting; insufficient watering during the active growing season; winter content at a fairly high temperature, for laying flower buds need cool.
Lower leaves fall, new ones grow yellowish - leaf chlorosis appeared due to the increased content of chlorine and calcium in the irrigation water, while there is a lack of nitrogen and iron (it is necessary to defend the water for irrigation and add iron chelate to it according to the instructions); disease of roots from hypothermia with abundant watering and low temperature; too dry indoor air combined with high temperature and insufficient spraying.
Of pests on hibiscus are aphid, thrips, whitefly, spider mite. To combat them use appropriate drugs. If your hibiscus is pretty naked, cut it off after pest release, so that the side shoots appear, the plant will soon be lush again.
From a young plant you can grow beautiful standard tree. To do this, you need to tie up the central shoot to a straight support, and cut off all lateral ones, leaving 3–5 leaves each. This will contribute to the thickening of the trunk. During this period, fertilizing the plant with a high nitrogen content is made. When the hibiscus grows to the desired height, you need to pinch the top of the head, leaving 5-6 well-developed upper lateral shoots. It is from them that the crown is formed, producing frequent pruning, as a result of which the crown will branch more strongly. Then it will be possible to remove all the lower side shoots.
Hibiscus, due to its unpretentiousness and tolerance, has been one of the most favorite tub plants for many decades. And its luxurious flowers - a worthy reward for good care.
