Pruning and pruning:?

Azaleas grow slowly. Generally, they are allowed to grow naturally. They are only trimmed after flowering and cut off leggy branches, diseased branches, deformed branches, and damaged branches. , apply a healing antiseptic film to the wound after pruning to make the wound heal quickly.

Rhododendron prefers acidic soil that is loose, highly permeable, well-drained and rich in humus, with a pH value of 5.0-6.0. If you use clay or alkaline soil, you can get rid of all difficulties. Especially summer cuckoos and cuckoos must be grown in mountainous soil. The mountain soil also needs to be modified, and three types of culture soil are usually used. (1) Mix and prepare 7 parts of mountain soil, 1 part of dry moss grass clippings, 2 parts of dry leaf rot soil, and 1 part of dry fertilizer. (2) 3 parts of mountain bark soil (topsoil), 3 parts of horse manure, 3 parts of fallen leaf weeds, and 1 part of human excrement are piled in layers. After 1-2 years, they are screened and set aside.

Azaleas are resistant to pruning, and hidden buds can easily germinate after being stimulated. This can be used to control the tree shape and rejuvenate the tree body. Generally, pruning is done before May so that the new shoots can form flower buds that year. If it is pruned too late, it will affect flowering. Generally, the new shoots that germinate around the beginning of autumn can still become lignified. If new shoots are formed too late, they will be susceptible to freezing damage in winter.
