Sowing is one of the most common ways of propagation of primrose. The time of seed collection is generally in May and June. After harvest, we should sow early, usually at the end of June.
It is better to use a soft, thick and breathable matrix. Sowing is usually done in a shallow basin or box. After selection, a part of matrix is put into it first.
Because its seed itself is thin and small, it can be mixed into a part of the substrate first, and then spread them to the soil surface together, so the effect is better. It is better to spread the seeds evenly. It is the same as sowing seeds directly. After sowing, cover it with a thin layer of fine sand. The thickness should not be too thick, just a little without seeds.
1. Maintenance: three points need attention. First of all, water should be poured after sowing, and then the substrate should not be too dry, and some water should be added properly. And then there is the light, which needs to be placed in the place where the light is weak. Another is to cover a glass plate above the container. If the light is strong, you can also cover a newspaper
2. Transplanting and potting: generally from one week to ten days, it can sprout. The seedlings need to be transplanted and potted. The best choice for a new basin is a basin with a diameter between 12 and 16 cm. After the basin, also pay attention to the maintenance.
