Chestnut is suitable for growing in the range of annual average temperature 10- 17℃. The average daily temperature in the growing period (April 4- 10/October) is 10-20℃, the temperature in winter is below -25℃, and the suitable temperature in flowering period is 17-27℃, which will affect pollination and fertilization if it is lower than 15℃ or higher than 27℃.
