The tenon is a genus of perennials belonging to the Astrov family. According to molecular biology research, its original homeland is North America, from where this plant migrated to other continents and formed different species.
This representative of the Asterovs has strong roots, very tall shoots, from which appear inflorescences, sometimes reaching 25 cm, they consist of small flowers of white or pink color. The leaves are large, formed throughout the shoot.
Since this is a tall flower, it is usually planted on the backs of flower beds. He looks good in the compositions and independently. Suitable for decorating ponds. The great advantage is that it does not crowd out other cultures and can be combined with them.
Tender varieties and types
The most famous and popular in our area is Monk purple. It comes from North America. The shoots of this perennial reach a height of one and a half meters, slightly cast blue.
The leaves are large, rounded, lanceolate. Inflorescences are chenvate, of small size, may be of delicate scarlet, white or purple flowers. It starts blooming in the middle of summer and lasts a little more than a month.
Stevia spotted also comes from North America; this species looks rather rough - its stems are under two meters, the foliage is long, and the inflorescences are purple in color. This species and its varieties rarely pay attention, choosing perennial plants, but despite this, it hibernates well and looks beautiful almost until the leaves fall.
Konklyu The area of natural distribution is Europe, mostly wet, marshland. This species is not as tall as the congeners and reaches only half a meter high. Leaves on short petioles, slightly pubescent. Inflorescences-baskets appear on top of the stem in July, the flowers pink color.
Stems wrinkled The main difference of this species from others is the opposite leaves with teeth, as well as white inflorescences.
From these and other species many varieties were bred, among them:
Watering the park
You also need to conduct watering and, until the seedlings are rooted, you need to water regularly. After rooting, watering is reduced, but all do not exactly allow the soil to dry out.
In hot weather, watering for this lover of moisture is also simply necessary.
Plant transplants are rarely carried out, since the bushes of an office can up to 10 years retain a decorative appearance. Due to the fact that the rhizome of this plant is strong and quickly turns to wood, the procedure of transplanting and dividing, which are carried out together, is quite problematic.
It is better to start the procedure in spring. To begin, shoots need to be cut so that they become about 20 cm in height. After that, the root is shared, but it is difficult to do, so you can even resort to an ax. When dividing, care must be taken to have at least three buds on each part.
Delenki treated with charcoal and transplanted into places suitable for the cultivation of adult plants.
Fertilizer for stevia
This garden crop is a good fertilizer. Best of all, she perceives complex soluble mineral supplements like “Kemira”, nitroammofoski.
The first time fertilizer is applied in spring, the second - at the beginning of summer and the last with the formation of buds.
Monument to the preparation for winter
After flowering, inflorescences pruned. Before hibernation, all shoots are cut so that only 10 cm of length is left of them.
In the middle lane, the stepton child normally tolerates cold and does not need warming for the winter. In the spring, it does not expel greenery for a long time, right up to May, so do not be afraid that something is wrong with your bush.
Miller reproduction seeds
There are several ways of breeding centered. One of them is seminal.
Sow seeds in March. To do this, use any nutritional mixture, which is simply sprinkled with the material, due to its small size.
Planted watered with diluted potassium permanganate and covered with glass. From time to time produce watering and ventilation. Shoots will begin to hatch after about 14-20 days. When this happens, the glass or film is removed.
With the formation of the seedlings 4 of these sheets, you can dive young plants in separate containers. Flowers are planted in the garden in May, when a stable positive temperature is established.
Flowering from seed obtained from plants may not occur until the age of three. Also the nursery boy breeds normally by self-sowing.
Reproduction of boneset kidney
On the division of the bush was described in the previous section. We only note that one can start the division only if the plant is already 5 years old.
You can also use the kidney recovery. They are cut in the spring along with part of the root, when the stems are about 5 cm. Such cuttings are planted in containers with nutrient soil, held in partial shade and watered. When rooting is completed, it is possible to plant in open soil.
Miller reproduction by cuttings
Green cuttings collected in early July. They are cut so that each has 3 buds and rooted in the greenhouse, watering in time to keep the soil moist.
In the middle of August, it is usually possible to transplant the cuttings to a flower bed.
Diseases and pests
The tenant is very attractive to gardeners because it is not afraid of diseases, and the pests do not touch it, because the plant is poisonous.
Sometimes there is a defeat. minerwhich is disposed of by the removal of sharpened foliage and treatment with an insecticide of the Actellica type.
The main questions that arise from gardeners are late sprout in spring, which is quite normal, and the lack of flowering, which is due to lack of light or young age of the bush, obtained from the seeds.
