Why the hibiscus does not blossom? Secrets of successful cultivation
In the 18th century in botanical gardens and greenhouses of Europe the charming unpretentious plant from family of malvovy - the Hibiscus appeared ( of Hibiscus ) . A sort it from Hugo`s tropics - East Asia and in the nature meets in the form of grassy plants, listopadny and evergreen bushes and small trees.
Now there are several hundreds of forms and grades of a hibiscus which are grown up in decorative gardening and room floriculture. It is famous for the charming flowers of the most different coloring, they happen simple and terry and appear on a plant within several months.
The hibiscus Chinese ( of Hibiscus rosa - sinensis ) with darkly - green brilliant leaves and magnificent red terry flowers for which he was nicknamed a rose tree Chinese is long since widespread in room culture . It quickly grows and at good leaving easily turns into a large sprawling tree. We will also talk about it.
of the Condition of keeping the Hibiscus Chinese is quite unpretentious
and tenevynosliv, but it is preferable to keep it in rather light room , avoiding hit of direct sunshine. It is one of conditions for good blossoming. It is useful to expose a plant on fresh air to the light place protected from wind in the summer. Optimum temperature of contents is within 18 - 22 °C.
The period of blossoming of a hibiscus Chinese is the share usually of spring, summer and fall: its krone is periodically decorated by magnificent single terry flowers. Watering has to be regular and plentiful after drying of the top layer of earth at this time. The earth after watering needs to be loosened to provide access of air to roots. Strong redrying of the soil during this period is inadmissible , otherwise the plant will dump foliage and buds. In the winter waterings reduce.
The hibiscus is very sympathetic on application of fertilizers , in the veseena - the summer period an adult plant about 3 times a month feed up mineral fertilizers or weak solution of organic chemistry. In winter time feed up weak solution of fertilizers once a month.
Daily sprayings , especially during the winter period are useful at contents in the warm heated room with dry air.
And now - attention! complaints of flower growers Very often meet that supposedly I care - I cherish the rose tree - and on the sun I hold, both I water regularly, and I feed up, and it does not blossom - though burst! And you will look in some shop or establishment - there is to itself in the dark hall a tree forgotten by all in a tub, nobody especially looks after him, water as it is necessary, and it blossoms, without ceasing. Familiar picture, truth?
And all the matter is that to laying of flower kidneys at the Chinese rose tree is promoted by air temperature about 15 °C . At such temperature and the soil dries out slowly, therefore, it is necessary to water it absolutely seldom. And it is the main secret of receiving magnificent flowers . As a rule, such conditions in the state institutions mentioned above develop in the fall when still the heating season did not begin, and a cold snap already notable. At this time it is indoors very cool and the hibiscus falls into a condition of rest, actively putting rudiments of flower kidneys which become more active with arrival of spring.
Pay attention that in apartments with a central heating there are similar conditions in the fall, and it is necessary just to use them not to disturb a plant correctly to have a rest. And with inclusion of heating it is only necessary to place the hibiscus in the most cool place of the apartment (even in low-lit) and not to disturb until the end of winter excess waterings.
Awakening comes approximately in February, it can be noticed on the beginning gain of young leaves. Then the plant is rearranged to the light warm place and begin to water and feed up gradually. If the moment of awakening is missed and you will rearrange a hibiscus already with buds, then be ready that at sharp change of a microclimate it can dump the first buds and even partially foliage. Then, of course, will make up, but it is better not to arrange it such extreme.
Landing and reproductionis necessary for
For cultivation of a hibiscus friable and very nutritious pochvosmes, consisting approximately of 2 parts of cespitose, 1 part of sheet and 1 part of the humous earth, it is possible to add a little peat and sand. At the bottom of a pot surely stack a drainage.
Young plants grow very quickly therefore change in a pot, bigger by the size, can be necessary for them within a year not once. Further in annually early spring they need to be replaced in a fresh fertile soil. Adult plants are replaced seldom, but replace with it the top layer of earth in a pot on fresh, more nutritious in every spring.
At the end of winter it is useful to make cutting of an adult plant, it stimulates plentiful branching and blossoming. Branches cut off on two thirds or half. The received shanks serve as material for reproduction. They quickly enough let out backs in water or at placement in a parnichka in a friable substratum. For reproduction it is possible to cut off tops of young escapes not only in the spring, but also in the summer, it is better in August. Young plants at good leaving blossom already several months later.
On a hibiscus buds appear, but do not reveal and soon fall down - the plant lacks nutrients; watering insufficiently plentiful, the soil strongly dries up; low air temperature.
Lack of flowers in the presence of magnificent numerous foliage - the plant is overfed with fertilizers with the increased content of nitrogen; lack of lighting; insufficient watering during active vegetation; winter contents at quite high temperature, for laying of flower kidneys the cool is necessary.
The lower leaves fall down, new grow yellowish - arose hloroz leaves from - for the increased content in watering water of chlorine and calcium, at the same time there is no nitrogen and iron (it is necessary to settle water for watering and to add to it iron chelate according to the instruction); a disease of roots from overcooling at plentiful watering and low temperature; too dry air indoors in combination with high temperature and insufficient spraying.
From wreckers on a hibiscus a plant louse, tripsa, the whitefly, a web tick happen. Apply the corresponding preparations to fight against them. If your hibiscus fairly became bare, after release from wreckers cut off it that lateral escapes appeared, soon the plant will be magnificent again.
From a young plant it is possible to grow up a beautiful standard tree . For this purpose it is necessary to tie up the central escape to a direct support, and lateral to cut off all, having left 3 - 5 leaves. It will promote a trunk thickening. During this period make top dressing of a plant fertilizers with the high content of nitrogen. When the hibiscus grows to desirable height, the top needs to be prishchipnut, having left 5 - 6 well developed top lateral escapes. Here also form krone of them, making frequent cutting as a result of which the krone will branch stronger. Then it will be possible to remove all lower lateral young growth.
The hibiscus, thanks to the unpretentiousness and tolerance, already is many decades one of the most favourite kadochny plants. And its magnificent flowers - the deserved reward for good leaving.
