Pruning in growth period: light pruning in growth period, mainly to drain dense branches and prune branches of diseases and pests, to promote more vigorous growth.
Pruning during dormancy: Re-pruning should be carried out during dormancy, and all branches and leaves with poor growth can be cut off to reduce excessive branches.
Trim shape: You can also trim according to your favorite shape.
First, pruning at seedling stage
Photinia rubra is adaptable and resistant to pruning. It is best to prune many times at seedling stage, mainly by topping, so that the nutrients are more concentrated. Only in this way can more lateral branches germinate, the plants become more plump and beautiful, and it is also convenient for later modeling. The method of topping is very simple, just cut off the top part of the branch directly with special tools. The specific topping times can be carried out according to the shape and growth you want.
Second, pruning during the growth period.
Photinia rubra is a very pruning-resistant plant, which can be pruned at any time during the growth period, but only slightly during the growth period. Excessive pruning will affect the growth and germination of branches and leaves. At this time, pruning is mainly aimed at over-dense branches, pests and diseases, appropriately cutting off over-dense branches and leaves to promote better ventilation and light transmission inside. Once pests and diseases are found, they should be cut off so as not to affect the growth of other robust branches and leaves.
Third, dormant pruning
Photinia rubra can be pruned again during dormancy, and reasonable pruning is not only beneficial to overwintering, but also can promote the better germination of new branches in the coming year. At this time, all the branches and leaves that are not growing well should be pruned. It is also necessary to prune the branches that were too vigorous in that year and reduce them appropriately to promote the concentration of nutrients, thus promoting the germination of new branches in the coming year.
Fourth, trim the shape.
The common shapes of Photinia rubra are cylindrical, short spherical, cubic and hedgerow. The specific pruning method can also be trimmed according to your favorite shape, and it will be shaped after repeated pruning and shaping, and the shape will be more beautiful.
