Rhododendron prefers soft soil with good air permeability, preferably rich humus, in which it will grow better and faster. The best pH value of soil is 5.5-6.5, that is to say, it likes acid soil. Moreover, the drainage of the soil is also better, because the plants are afraid of ponding. If the ponding can be quickly discharged from the flower pot, it is also very beneficial for the growth of the plants. In order to make it grow better, we should not use the soil which is too sticky and heavy and has poor permeability.
The cultivation of Rhododendron in the area north of the Yangtze River is mostly pot culture. When mixing with soil, rotten leaf soil, sandy soil and the same soil can be mixed with some base fertilizer, which can be used after mixing. In the south of the Yangtze River, most of the area is cultivated with land, using acid sandy loam.
No matter how the culture is carried out, the soil used for cultivation shall be fine, and large pieces of soil shall not appear, and bacteria and insect eggs shall not be inside. So before planting azalea, you need to put it in the sun to disinfect.
