Methods for pruning rhododendrons:
During the growth period, promptly prune off the sprouting branches at the base, as well as the channeling branches and leggy branches that are higher than the crown to maintain a beautiful crown. Wipe the buds in time, wipe out the dense buds, reduce the density of branches to allow ventilation and light transmission. After the flower buds are formed, peel off the dense flower buds in time to reduce excessive consumption of nutrients and promote plant growth. For plants with incomplete tree shapes, short long branches or topping can be used to stimulate multiple branches in the defective part to complete the crown.
Rhododendron pruning techniques:
1. Selection of tree shape
According to the branching habit of azalea, it is generally shaped and pruned into a main trunk round head shape and multiple trunks. Oblate round shape.
2. Plastic pruning technology
1. Propagation and pruning: 1-4 year old rhododendron cuttings have a small crown. Pruning can be combined with transplanting. Mainly through Thinning branches and topping will form the basic skeleton of the plant as soon as possible and expand the canopy. Determine the branches based on the round head shape and the oblate shape of multiple branches. When the new shoots grow to 5-6cm, if the plant is growing vigorously, topping can be carried out. Generally, it can promote 2-4 branches and keep 2. Continue topping after 2-3 years. When the branches reach more than 20, the crown has A prototype. During the growth period, promptly prune off the sprouting branches at the base, as well as the channeling branches and leggy branches that are higher than the crown. Wipe the buds in time, wipe off the dense buds, reduce the density of branches, allow ventilation and light transmission, and promptly peel off the formed flower buds to reduce excessive consumption of nutrients and promote plant growth.
2. Pruning to cultivate large seedlings: When the skeleton of the rhododendron plant is basically formed, the crown is not yet perfect, and it is in the initial flowering stage, pruning after flowering is the main method, supplemented by pruning in autumn and winter. If you are not considering leaving the garden in the short term, you can also prune before flowering to reduce excessive consumption of nutrients. In the Peida period, azaleas mainly use sparse branches and long branches in the early stage to form a crown as soon as possible, and sparse branches and flowers in the later stage to maintain the integrity of the crown and flowering rate. Before flowering in spring, thin out dense branches, dead branches, weak branches, cross branches, overlapping branches, diseased dead branches, sprouting tillers, etc. to facilitate ventilation and light transmission. After the flowers fade in spring, the remaining flowers will not fall off easily. Cut the branches of the remaining flowers in time to promote branching and reduce nutrient consumption.
