My azaleas withered and my leaves fell off. What should I do?

Extended data:

Rhododendron, also known as Yingshanhong and Shan Shiliu, is an evergreen or ordinary green shrub. According to legend, there was a cuckoo in ancient times, which crowed day and night, hemoptysis, and dyed flowers all over the mountain, hence the name. Rhododendrons usually bloom in spring, with 2-6 flowers in each cluster. Corolla is funnel-shaped, with red, pink, apricot, snow blue, white and so on. , gorgeous colors.

Rhododendron likes a cool, humid and ventilated semi-cloudy environment, which is afraid of extreme heat and cold. When the temperature exceeds 35℃ in summer, the new shoots and leaves grow slowly and are in a semi-dormant state. Sun protection is required in summer, and attention should be paid to keeping warm and cold in winter. Avoid exposure to the scorching sun, and it is suitable for growth under scattered light with low light intensity. If the light is too strong, the young leaves will be easily burned, and the old leaves will also be scorched, which will lead to plant death in severe cases.
