Baby cabbage is considered to be a semi-cold-tolerant vegetable variety because of its loose temperature requirements. Baby dishes with light frost are not afraid, but those with heavy frost will not be harvested. The suitable growth temperature is 17 -22℃. If the average temperature is higher than 25℃, the yield of baby cabbage will be poor. If the temperature is lower than 10℃, its growth will become very slow. If the short-term temperature is 1 -3℃, the frostbite of baby cabbage can be recovered, but if it stays at 1 -3℃ for a long time, it will freeze.
