When is the right time to grow ginger in Beijing?

Ginger is usually sown in spring and harvested before frost. Ginger is planted in early spring in March, and the surface temperature measured before sowing must be above 65438 02℃. Ginger is harvested in autumn and September.

Ginger is a perennial herb of Zingiberaceae. Ginger is native to tropical areas of Southeast Asia. I like warm and humid climate, and my ability to resist cold and drought is weak. These plants can only grow during the frost-free period. The optimum growth temperature is 25-28℃. When the temperature is lower than 20℃, the germination is slow, the plants wither when exposed to frost, and the roots completely lose their germination ability.
