  • 1. Temperature requirements: the optimal growth temperature is 16 ~ 24℃, 18 ~ 24℃ from April to October, and 12 ~ 16℃ from October to April of the following year. The temperature should not exceed 30℃ in the daytime, the high temperature is not good for the growth of African violets (I do not know whether it is wool ~). If the outdoor temperature exceeds 30℃ in summer, the water should be given timely shading.
  • 2. Lighting requirements: African violets need shade in summer with green leaves; Winter is full of sunshine, to bloom constantly; Rain and snow combined with supplementary light are very beneficial to the growth and flowering of African violets. If the light is insufficient, it will Flower less and light, even only long leaves do not blossom; If the light is too strong, it will cause the phenomenon of yellow leaves, dry coke. It can be placed in the light bright and no direct sunlight maintenance.
  • 3. Humidity requirements: in the process of cultivation, we should keep high air humidity, appropriate watering, do not make too wet, so as to avoid stem and leaf rot. The difference between water temperature and air temperature should be less than 5℃, otherwise, there will be a large number of yellow spots on the leaves.
