After seed sowing and emergence, you only need to keep moisturizing and keep warm, buckle a small arch shed on the seedling bed, and then spray water every day. Dissolved fertilizer can be applied when growing to about 4 cm.

2. Fast-growing period

The seedlings can be planted when they grow to about 10 cm, and the planting density can be a little tighter for heat preservation. But not too tight, do not manage, the disease is easy to spread. After planting, it will be dehydrated for a few days. Spray water every day to help stand upright.
