2. Sowing time

The sowing time can be in summer or autumn, but August to September is the most suitable. There are 300 seeds per gram, and the sowing amount is about 1 kg per mu. If calculated according to each square meter, it should be 1: 2 grams per square meter. If spray seeding is adopted, it is best to increase the amount per unit area by 1020%.

Mix the basin soil with garden soil, perlite and plant ash at 6:2:1, apply sufficient basic fertilizer when potting, and move the basin to a sunny place for routine fertilizer and water management.
