Black root breeding
Tsinoglossum prone to self-seeding; when it’s nice, and when it’s not very surprising at the rate of its spread. This quality is an indispensable source of improvisation effect for compositions in landscape styles. But in ensembles where such distribution is undesirable, cinoglossum should be used with caution. Young shoots can be transplanted using as seedlings.
But the main method of propagation of black root is still sowing seedlings. The seeds of this plant are best sown in large containers or boxes using a loose, fertile substrate. The optimal time for sowing is the third decade of March or the first decade of April. Seeds cannot be deeply buried: after scattering on the soil surface, they are only covered with a thin layer of sifted soil. They can germinate only in the dark, under glass or film, in the temperature range from 18 to 24 degrees Celsius. Weak seedlings need careful, accurate watering, which should be carried out only as the substrate dries.
Seedlings can be brought to light only after the friendly emergence of seedlings. In this case, the glass is removed as the plants grow, and the dive is carried out after the appearance of several pairs of true leaves.
Planting seedlings in the open ground can be carried out already in early May: cynoglossum is not afraid of light short-term frosts, it does not need to be planted at the end of the month or June. Before transplanting, seedlings need to be hardened for 1-2 weeks in the garden.
Black root can be sown directly in open soil. Seeds are scattered on 3-5 pieces in one nest, immediately placing them at a distance of 25-30 cm between groups. Shoots will appear after 2, sometimes 3 weeks. The advantage of sowing directly into the soil is the plant's great resistance to heat, drought, and nighttime cooling.
