The pruning of Sophora japonica follows the principle of sparseness and strength retention, keeping healthy and stout branches for short cutting, cutting off the parts with new buds at the top of branches, cutting off dead branches, tender branches and diseased branches on plants, sorting out the crown shape, ensuring uniform distribution and forming an umbrella-shaped skeleton.

Pruning method of Sophora japonica

When Sophora japonica is dormant, it is necessary to prune the branches and cut off the dead branches, tender branches and diseased branches growing on the plant, so as to avoid affecting the health of the whole plant, and avoid unnecessary loss of water and nutrients of the plant and ensure that the branches grow more vigorously.

During the growth of Sophora japonica, we should always pay attention to the growth of the whole crown and cut off all the upright, drooping and inward growing branches. The growth of these branches will affect the formation of the umbrella-shaped crown, and it is necessary to trim the whole crown into an umbrella-shaped skeleton.

Pruning overlapping, parallel and intersecting branches of Sophora japonica requires pruning the crown with layering to ensure that the trunk is evenly distributed, not too thin or too dense, providing more growth space for the leaves of the plant and improving the ventilation and light-transmitting environment of the plant.

When pruning Sophora japonica, we should follow the principle of thinning and retaining strength. Keep healthy and strong branches, and prune the branchlets, mainly pruning the lower parts of the branches and cutting off the base of the branches. The upper branches need to be cut short, and only the terminal buds need to be kept when they are cut short.
