Red beans mature from July to August.

The maturity time of red beans is affected by the temperature and environmental conditions of the growing area. The flowering period of red beans is between March and June in spring and summer. This period is the main stage of red bean flowering. After maintenance, it takes seven or eight years for the red beans to bear fruit for the first time. The fruit ripening period is from September to October, and around October is the peak ripening period for red bean fruits. The pods of red beans contain 1-2 seeds, which are usually bright and brightly colored. After the red bean fruits are ripe, they can be picked and harvested. The growth and maturation time of red beans are also affected by other factors, such as soil conditions, water supply and light.
