Osmanthus cultivation method
1, temperature control
Osmanthus prefers a warm environment, the optimal growth temperature between 16 to 26 ℃, so in the process of cultivating the osmanthus we have to do a good job in the corresponding temperature control Measures to ensure that the temperature does not exceed 32 ℃ in summer and not below 0 ℃ in winter. In the southern region, osmanthus can overwinter outdoors, but in the northern region, it is recommended to move it into the greenhouse in winter.
2, light demand
Osmanthus prefer diffused light, in the process of breeding to ensure that the plant's light conditions, will be placed in the light of a better place to maintain. But the summer light is too strong, direct light is easy to appear sunburn, so in the summer to do a good job of shade measures, so that the plant is in a semi-shade environment can grow.
