Pay attention to changing pots after azaleas.

Choose a pot according to the size of the plant to choose the appropriate flowerpot, to clay pot is good, the general pot diameter (inner diameter) should not exceed half of the crown diameter. Azalea like acidic soil, pH requirements in 4.25-5.5, do not maintain this acidity, potted azalea is difficult to survive, and basin soil requirements loose drainage, rich in humus, do not use sticky heavy loess.

When using soil, it is best to prepare according to the original soil of rhododendron. For plants cultivated in pine soil in the past, pine soil should still be selected, and a small amount of decomposed horse dung and bone powder can be mixed. When using, the pine soil should be infiltrated with water in advance; if it is cultivated in mountain soil, mountain soil should also be used. If the original pine soil cultivation is used pine soil, the reverse side will be too strong because of its water permeability, resulting in the original lump outside wet and dry and die, while the original pine soil cultivation is replaced by mountain soil cultivation, easy to cause long-term wet pine soil, affecting the root absorption growth, serious, will lead to part of the root suffocation death, so that the plant leaves, yellowing, new shoots stop growing. Rhododendron is a shallow root plant, no main root system, fibrous roots are thin and many, mainly distributed in the upper part of the basin soil, forming a felt mass, not easy to penetrate deep.

Therefore, when putting on the pot, first cover the drain hole with 2 tiles in the shape of "in," cover a layer of coarse sand as the drainage layer, then gently cut off 1/3 of the old soil and rotten roots of the plant, sprinkle a layer of culture soil on the drainage layer, then put the plant in the pot, keep a distance of about 3 cm between the soil lump and the pot wall, then fill the prepared culture soil into the gap around, gently press it with a thin stick, let the pot soil and roots develop, finally pour water thoroughly, put it in a semi-shady place, and turn to normal management half a month later.
