Especially in coastal cities, lettuce is widely grown, appearing not only in greenhouses but also on ordinary people's balconies.

Growth habits of lettuce

Lettuce prefers a cool environment and is neither cold-tolerant nor heat-tolerant. The most suitable temperature for growth is 15-20°C, and it can be harvested 90-10 days after sowing. The seeds are relatively tolerant of low temperatures and can germinate at 4°C.

When the temperature remains above 25°C, growth is poor, the leaves become coarse and old, and there is a slight bitterness. However, it is also quite cold-tolerant, and 0°C or even short periods of subzero low temperatures do not greatly hinder growth.

Lettuce has a well-developed root system and a waxy leaf surface, giving it strong drought tolerance, but when cultivated in fertile, moist soil, the yield is high and the quality is good. A soil pH of 5.8-6.6 is suitable.

The symbolic meaning of lettuce

Because the pronunciation of lettuce sounds like "sheng cai" (making money), it carries the beautiful meaning of gaining wealth. It is more commonly used in southern regions.
