1. Temperature

Rhododendron likes cold, not high temperature. Therefore, in winter, the southern region should be an ideal living environment, which can grow well indoors and outdoors. In the north, it is necessary to adjust the temperature above 5 ℃. If the temperature is adjusted to 10-15 ℃, it can grow slowly. If the temperature is adjusted above 15 ℃, its growth rate will be accelerated

2. Humidity

Rhododendron likes humidity, but it is dry in winter, especially in the north, because the supply of heating will make the air too dry. At this time, we need to do a good job of humidification and humidification

3. Illumination

The light in winter is not very strong. Let the Rhododendron receive some scattered sunlight in the morning and evening

4. Water supply

Winter is the flowering period of Rhododendron. It is necessary to ensure the temperature of water supply, not dry or wet, so as not to shorten the flowering period. In addition, do not spray water on the azalea during the flowering period to prevent its flowers from aging early
