Sow from April to October in warmed soil, directly in place on well-loosened ground. Mix seeds with sand and sow evenly. Lightly cover the seeds with soil using a rake. Do not sow during hot and dry periods; on dry soils, it is best to sow in the fall. Do not let the seeds dry out. Loosen and fertilize the soil, protect the sowing from slug damage, and cut back to 15-20 cm in the fall.
