Growing African violets

Growth habits of African violets: African violets like warm, humid and semi-overcast environments. They are afraid of strong light and high temperatures in summer. Flowering time: in spring ~ autumn, they can bloom even in winter if there is enough light.

Common cultivars: large flowers, single, semi double, double, variegated, purple, white, blue, pink and two-color, etc. The most cultivated varieties are single - petal snow prince. The following are details of growing African violets.

  • 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.
  • 4. Fertilization: Every 7 to 10 days in the growing season of African violets applied a thin liquid fertilizer or compound fertilizer. The nitrogen content of fertilizer should not be too much, otherwise the leaves will grow luxuriant and few flowers.
  • 5. Summer care: keep it in a ventilated and cool place in summer to avoid hot and humid environments and hot sun exposure. At ordinary times water should not be too much, to wait for the basin soil a little dry again. Basin soil water is often the main cause of plant rot.
  • 6. Winter care: The ambient temperature in winter shall not be lower than 10℃, otherwise it is vulnerable to freezing damage. The relative humidity of 40 {bf} ~ 70 {bf} is more appropriate. The soil is too wet and easy to rot roots. The air is dry and the leaves lack luster. Avoid sharp rises and falls in temperature, or the plant will die easily.
