1、 Picking flowers and pruning

After the flowers of Rhododendron wither gradually, the remaining flowers should be cut off as soon as possible to avoid wasting water and nutrients and make the plant have the ability to accumulate nutrients. At the same time, the branches should be trimmed. The weak branches, sick branches and branches that affect the internal ventilation and light transmission should be cut off to avoid all kinds of diseases and pests caused by poor air circulation

2、 Enhanced illumination

Because azaleas are generally placed indoors during flowering, the light will be greatly reduced. After flowering, you need to gradually increase the light. However, due to the strong light in summer, you can't put it under the light immediately. You need to slowly adapt to the scattered light

3、 Increase watering

Generally, there is less watering during the flowering period, and it should be increased slowly after flowering, so that the plant can absorb enough water. Generally, water once a day in summer and once in two to three days in autumn. In addition to daily watering, you can also spray water on the leaves to improve the humidity of the air

4、 Timely topdressing

Fertilizer should be applied in time after flowering, generally once every 15 days. When the temperature is high, the growth of Rhododendron slows down, and fertilization can be stopped
