Rhododendron habits like warm, semi-overcast, cool, ventilated, moist environment. Loose, fertile, humus-rich acidic soils are required. The suitable growth temperature is 12 ℃ to 25 ℃, shade and sunscreen in summer and frost protection in winter. It is best to move indoors.

1. Rhododendron is suitable to be planted in a muddy basin, because the mud basin absorbs water and breathes air, which is beneficial to the growth and development of roots and luxuriant branches and leaves.

2. Put the potted azaleas in a ventilated place and move as little as possible. If it is not ventilated, it is easy to suffer from black spot disease and a large number of fallen leaves.

3. Cuckoo illumination, avoid direct light in summer. Fertilization should grasp the application of thin fertilizer frequently, can be light but not thick, and apply organic compound fertilizer on the basin soil once a month. Potassium dihydrogen phosphate was sprayed every 10 days for extra-root fertilization. Timely watering, you can also put edible vinegar in the water to increase acidity.

4. The main reasons for azaleas falling leaves and not blooming are: too much direct light in summer, frostbite, too much watering, too thick fertilization, too long indoor time, poor air circulation or dark and humid places, so these situations should be avoided in the process of maintenance.

5. Turn the basin and change the soil, usually once every 2 to 3 years, with as little damage to the roots as possible, in autumn, while spraying topiramate to prevent diseases.

6. The pests of azaleas are mainly red spiders and aphids, which can be sprayed with permethrin, and the effect is better, such as not dying after three days, spray again. The disease is mainly black spot, which is caused by muggy environment and lack of light. Bordeaux solution and carbendazim can be sprayed.

7. After the cuckoo blossoms, its residual flowers often last for a long time, which consumes a lot of nutrients. In order not to let nutrients be consumed in vain, the residual flowers should be picked in time to supply nutrients to sprout new technologies. Trim all the overdense branches, inner bore branches and weak branches, the thinner the pruning, the better, to maintain good ventilation, the better!
