The planting time of cabbage

Chinese cabbage is planted in July and August every year. Cabbage is relatively cold-tolerant and likes cold weather, so it is suitable for growing in the cold season. If cultivated in high-temperature seasons, diseases and insect pests are prone to occur, or the quality is poor and the yield is low, so it is not suitable for cultivation in summer.

It is very resistant to low temperatures. After the temperature reaches -3℃, if the temperature can be gradually raised, growth can be resumed. However, if after reaching -8℃, the temperature continues to drop to about -11℃, it will not be able to resume normal growth and suffer frost damage.

Chinese cabbage is suitable for planting in loam, sandy loam and black loess soil that retains fertilizer, water and is rich in organic matter. It is not suitable for planting in sandy soil that is prone to leakage of water and feces, and it is even less suitable for planting in poorly drained clay. .
