Broad bean sowing time

It is understood that the planting time and methods of broad bean are different in different places, and the temperature required for different growth periods of broad bean is also different.

Autumn broad beans are generally planted around October in the south; the sowing time along the Yangtze River is concentrated between Cold Dew and Frosts Descent, that is to say, the middle reaches of the Yangtze River is in late October, the lower reaches of the Yangtze River is in mid-October, and South China and Zhejiang are in late October.
