How long is the growing cycle of lettuce?

Introduction to Lettuce Growth

Lettuce is mainly distributed in China, Mongolia, North Korea, Japan, Vietnam and India. It is often grown in mountain forest edges, meadows, bushes, river banks, lake sides, fields and roadsides.

Lettuce growth cycle

Lettuce is cold-resistant, prefers cool climate, large temperature difference between day and night, requires higher temperature for flowering and fruiting, and its growth cycle is about 80-100 days.

Lettuce growth cycle management

The yield of lettuce per mu is about 2,500 to 4,000 kilograms. Lettuce will enter the heading period about 70 days after sowing. The demand for nutrients during this period is the greatest, and the demand for nitrogen accounts for more than 80% of the total nitrogen in the whole process.

Temperature management: The best environment for lettuce growth is 12-18 degrees. During the day, the best environment temperature is 15-20 degrees, and at night it is best to maintain an environment of 10-1 degrees.

Fertilization management : After the lettuce forms a head, it should be fertilized with nitrogen, phosphorus, potassium organic and inorganic compound fertilizers, or foliar fertilizers and root topdressing. Generally, it should be applied once a week, and applied 3 to 4 times in a row.
