1、 Pruning during growth

The growth period of Rhododendron is in spring, which needs proper pruning. Because the new branches grow fast, they can recover better after pruning. The longer branches are cut short, and the weak branches and dead branches are cut off in time, so that its nutrients can be supplied to the stronger branches, which is also helpful for flowering

2、 Post flower pruning

Rhododendrons should be trimmed once after flowering. Because flowering consumes a lot of nutrients, the remaining flowers should be removed in time to enable the plant to recover growth faster

3、 Appropriate thinning

If the fertilizer supply is sufficient and the Rhododendron grows luxuriantly, it needs appropriate thinning. The time of thinning branches is uncertain. As long as the internal ventilation and light transmission are affected, the dense branches, especially the Cross branches and overlapping branches, should be cut off, which not only hinder the growth, but also easily cause diseases and pests

4、 Pest pruning

After the azalea is attacked by diseases and insect pests, the diseased branches and leaves need to be cut off. This can prevent the expansion of the disease and prevent its recurrence. If the condition is serious and can not be improved only by pruning, it is best to spray some medicine for treatment
