Ornamental plants are more often used in landscape design than in the design of the average small suburban area. But in small quantities, at least for the purpose of diluting the abundance of flowers, they are also necessary. Kohiya refers specifically to such plants: easily-formed bushes, stretching upwards by 1 m, arrived from China and have long since earned the love of gardeners around the world. In the middle lane, they also take root well.
Even in its homeland, kokhiya is an annual plant, therefore, no matter what conditions you create for it, next year you will still have to re-plant its seeds in the ground. However, even in such a short lifespan, the bush has time to grow widely, as a result of which it already requires molding at the age of 3-4 months. In fact, flowers even bloom on kohii, but they are so inconspicuous that they usually get lost because of the density of narrow elongated foliage, due to which kohia is called summer cypress. Remarkably, the shade of the leaves changes with the approach of autumn - in September it acquires purple-red notes.
It is quite simple to grow summer cypress from seeds, but it is important to remember that the plant is very delicate with respect to temperature instability. If the seeds grab the frost, they will die. Therefore, usually practicing gardeners sow kohia in greenhouses, and in the fall, adult bushes are provided with insulation according to the root zone. In the southern regions it can live until December, in the northern regions it often dies at the end of October.
When to plant kohiyu? Growing from the seeds of this shrub begins in April, if you work in a greenhouse, and at the end of May, if you want to sow kohia in open ground. At the same time, it is possible to tighten the sowing works until mid-July - the bush is pulled out quickly enough, therefore, such delays do not greatly affect its appearance in August-September.
After sowing, kohia must be watered frequently, perhaps even up to 2 times a day, if it occurs by spraying. Water should be warm, soft. Such a schedule is maintained up to 14-15 days from the time of sowing, after which watering becomes more rare. Shoots appear already at 5-6 days, and quickly gain strength, pulling up. In this case, no preparatory steps to accelerate the germination of seeds are not carried out: their germination is almost 100%. For the same reason, they need to be lowered into the ground one by one, without deepening or sprinkling with earth.
Kohia: landing and care
The soil for planting kohii is selected light, with sufficient addition of sand and ash as a top dressing, moreover, it is often necessary to add lime to the soil in order to lower its acidity. Also, gravel, which will assume the role of drainage, will not be superfluous: kohii should not be allowed to stagnate water in the soil, as well as brief waterlogging. It will be much more comfortable for the bush, even if you forget about watering it for a while - it is adapted to drought, and sometimes it is sufficiently natural to moisturize after the rains. The optimal schedule for watering kohii is once a week.
As for the location of the site on which the kohia will sit, it is best to choose the sun zones or slightly shaded: a strong shadow, in which the plant does not receive the sun rays for more than 30% of the day time, will cause the bush to grow weak and short, stop holding form. The same is possible if you plant a kohia too thickly: there must be a distance of 30-40 cm between specimens, which is necessary to create an individual feeding zone for each bush.
Feeding of kohii is carried out according to the following schedule: the period of active growth, falling on the first month after sowing, requires nitrogenous fertilizers; 10-14 days after sowing, mineral fertilizers, and after another 30-35 days they are repeated; during the growing season from fertilizers refuse. It may also require the introduction of nitrogenous fertilizers immediately after forming the bushes, which will contribute to their better branching. At the same time, the haircut is carried out up to 2 times a month, since the growth of the bush is active, and its shape can be changed almost every month.
Diseases and pests of kohia practically do not touch, practicing gardeners note only rare attacks of spider mites, which can be protected from rare spraying of bushes with coniferous or onion extract. If the pest has managed to damage the plant, the bush is treated with chemicals like "Neoron" or "Apollo" in a low concentration.

If you want to continue to grow kohia from seeds, keep in mind that when collecting from a bush, they remain viable for up to 2 years, in addition, the plant multiplies well and is an independent crop. True, it is not possible, of course, to track a specific area in which the shoots of kohii will be seen in spring. But you can again make sure that even without your participation, the bushes will easily take root and grow.
