1、 Soil

Rhododendron likes loose, fertile, weakly acidic soil with good drainage and air permeability. I don't like sticky and alkaline soil. Therefore, we can mix rotten leaf soil, peat soil and sandy soil in the proportion of five to two to three as the soil for raising it. Before planting or transplanting, a small amount of bone meal can be added to the soil to increase the content of minerals in the soil

2、 Temperature

The most suitable temperature for Rhododendron growth is 15-25 ℃. Try to let it grow in this temperature range in spring or autumn. Pay attention to temperature control when the temperature is relatively high in summer. The maximum temperature should not exceed 32 ℃. When the temperature is relatively low in winter, it should be moved to the house in time and keep the temperature above 5 ℃

3、 Watering

Watering azalea is a technical work. If you water more, it will rot its roots, and if you water less, it will dry its leaves. Generally speaking, we only need to keep the basin soil moist in early spring. In late spring and early summer, when it is ready to bloom, the water demand will increase greatly, so it should be watered a little more. In summer, the temperature is too high. In addition to watering, spray some water on the plants. In autumn, when the weather turns cool, you need to control the water appropriately and let the basin soil dry slightly. After it goes into dormancy in winter, it needs to reduce watering

4、 Precautions

1. Trim. Rhododendrons grow faster and grow very dense, which will lead to many internal branches and leaves can not see light and can not grow healthily. So we should trim it in time, which can not only make it more beautiful, but also make it healthier

2. Change the basin. The growth of Rhododendron needs to consume the nutrients in the soil. After a year or two, the nutrients in the soil will be absorbed by it. At this time, it should be replaced with new nutrient rich soil, so that it can continue to grow healthily
