Cultivation methods and key points of lettuce

1. Select variety

The selection of varieties for heading lettuce should be based on the environment of the breeding area, so as to achieve high survival rate and high yield. This type of heading lettuce is not easy to form during high temperatures in summer, and protective measures should be taken to prevent heatstroke and cool down.

2. Sowing and seedling cultivation

When planting lettuce, it is generally necessary to first treat the seeds. Soak the seeds in room temperature water for about 12 hours, then remove them, rinse them with clean water, wrap them in a damp gauze, and place them in a low-temperature environment for two days. Wait for about 80% of the seeds to first appear white before removing them for sowing. After sowing, cover the soil with about 1 centimeter.

Key points for daily management of lettuce

In daily management, lettuce mainly needs to prevent diseases and pests, such as sclerotinia and soft rot, which pose significant risks and are easily infected in warm and humid conditions. Therefore, it is advisable to reduce planting density appropriately, water not too many times, keep the soil surface dry and clean regularly, and effectively prevent them.
