The cutting of rhododendrons should be carried out before budding in spring or when the branches are semi-lignified in the early summer and autumn growth period. Seedlings can generally be processed from 3 to 4 years old, and are carried out year by year, first thick and then thin in the first two years. The main method is pinning. Usually, the main trunk and main branches are pricked properly. Rhododendron branches are brittle after lignification and are easy to break when pinning. To prevent future breakage when pinning, if the branches are growing well, the branches can be pruned before the branches are completely lignified. The head is bent according to the requirements of the shape. After the branches are thickened, prune the trunk. When the trunk is thick and hard, the bending is difficult. Use thick and hard wire to assist during the operation. Evenly pass the wire around the part that needs to be bent, and then use the opportunity to guide the side branches and branches. It is easier to bend small branches. Fix one end of the wire at the intersection with the main trunk, then wrap it around the side branches, and bend it by hand until it reaches the ideal angle without rebound
