Azalea like cool, moist, ventilated semi-shady environment, both afraid of extreme heat and cold, the suitable temperature for growth is 12 degrees Celsius to 25 degrees Celsius, the summer temperature exceeds 35 degrees Celsius, the new shoots and leaves grow slowly and are in a semi-dormant state. Sunscreen should be used in summer and warm and cold in winter. Avoid hot sun exposure, suitable for growth under scattered light with low light intensity, too strong light, young leaves are easy to burn, new leaves and old leaves scorched edge, serious will lead to plant death.

2. Temperature

The suitable temperature for the growth of rhododendron is 15 ℃ 25 ℃, the highest temperature is no more than 32 ℃, and the overwintering temperature is not lower than 5 mol. At the end of autumn around mid-October, azaleas should be kept indoors for maintenance. In winter, azaleas should be kept in a sunny place and the indoor temperature should be kept at 5 ℃ 10 ℃, but not less than 5 ℃, otherwise azaleas will stop growing or die.

3. Watering

When planting and changing soil, the rhododendron is watered once, so that the root system is in full contact with the soil, which is conducive to the survival and growth of the root. Cuckoo peanuts should be watered for a long time, especially in the middle of summer, must not be short of water, watering every morning and evening, and often spray foliar water to keep moist, but not stagnant water.
