But the difference of temperature in different places is different: in the rainy areas in spring, such as Fujian, Guangdong and Guangxi, it is suitable for afforestation from March to May, or from September to October if there is a water source for irrigation, and the planting season is relatively late in Hainan Province. the best afforestation season is from August to September.

Once a year before and after the rainy season, it is better to add one more time in the middle if possible.
