1、 Seed collection and sowing time

Sowing method is one of the most common propagation methods of Primula. The time of seed collection is generally in May and June. After harvest, it is best to sow early, usually at the end of June

2、 Matrix selection

It is best to use a soft, thick and breathable matrix. Generally, shallow pots or sowing boxes are used for sowing. After selection, put a part of the matrix into it first

3、 Sowing

Because its seeds are thin and small, they can be mixed into a part of the matrix first, and then spread them on the soil surface, which has a better effect. It's better to spread it evenly, which is the same as directly sowing seeds. After sowing, cover it with a thin layer of fine sand. The thickness should not be too thick. It can be a little less than the seed

4、 Curing and upper basin

1. Maintenance: there are three points to pay attention to. The first is water. After sowing, water should be poured through, and then the substrate should not be too dry. Add some water appropriately. Put the light where it needs to be weaker. Another is to cover a glass plate above the container. If the light is strong, you can also cover a newspaper

2. Transplanting in pots: generally, it can emerge in about a week to ten days. The seedlings need to be transplanted into pots after emergence. It is best to choose a basin with a diameter of 12 to 16 cm for a new basin. Pay attention to maintenance after putting on the basin
