growing environment

Durian is a pure tropical crop, and its phenological feature is that the daily average temperature of durian is above 22℃. Frost-free areas can be planted, and parts of China, Hainan and Yunnan provinces can be developed. ?

Because durian can only grow and bear fruit in the climate with high temperature all the year round, even in the equatorial region, the highland above 600m above sea level can not grow durian or bear fruit because of the temperature drop.

Durian grows all over Southeast Asia, mainly in Thailand, Malaysia, Indonesia and other places. Other places where durian is grown include Cambodia, Laos, Viet Nam, Papua New Guinea, Polynesia, Madagascar, northern Australia and Singapore, as well as China, Guangdong and Hainan.
