Osmanthus trees do not germinate in spring, which is caused by insufficient sunshine and ventilation. The growth habit of osmanthus trees is not strict with soil, except alkaline soil, low-lying land and soil that is too sticky and poorly drained. The slightly acidic sandy loam with deep soil layer, loose and fertile soil and good drainage is more suitable. Rainfall: the rainfall is average, with annual precipitation of about 1000 mm and humidity of 0.75-0.85. Sunshine: Generally, you need six to eight hours of light every day to avoid strong light or shade. Temperature: The optimum growth temperature is 15-28 degrees Celsius, and the lowest temperature can reach-0/0 degrees Celsius.
