Cabbage Habitat:

Cabbage was originally distributed in northern China and is widely cultivated throughout China. Cabbage is relatively hardy and prefers cooler climates, so it is suitable for growing in cooler seasons. If it is cultivated in the hot season, it is prone to diseases and insects, or poor quality and low yield, so it is not suitable for cultivation in the summer. It is very resistant to low temperatures.

After the temperature reaches -3℃, if the temperature can be gradually warmed up, it can also resume growth, but if it reaches -8℃ and then the temperature continues to fall to -11℃ or so, it can not resume normal growth and suffers from frost damage. Cabbage is suitable for planting in fertilizer, water and rich in organic matter loam and sandy loam and black and yellow soil, not suitable for planting in sandy soil that is prone to leakage of water and manure, and even less suitable for planting in poorly drained clay soil.
