How to prune Sophora japonica

There are generally two things to do when pruning Sophora japonica. One is to cut the stems at the right time. In spring, after the growth of Sophora japonica stops, you can cut off the curved part at the top of the Sophora japonica. In addition, for Sophora japonica plants that are two years old or older, if there is no main trunk or the main trunk is relatively tilted during the spring growth, the trunk needs to be pruned again. When cutting the trunk, start from the part where the main branch of the Sophora japonica begins to tilt.

Secondly, reasonable pruning is needed, and more side branches should be retained without affecting the growth of the main trunk of the Sophora japonica.

Principles of Sophora japonica pruning

When pruning Sophora japonica, horizontal or nearly horizontal branches are generally not trimmed, but allowed to grow naturally.

Branches that affect the growth of the main trunk of Sophora japonica need to be pruned off in time. Other side branches that do not hinder the growth of the main branches of Sophora japonica generally need to control their growth. As they grow, the side branches will gradually thicken. When the side branches reach half the thickness of the main trunk, they should be cut off in time.

It should be noted that if the branches of Sophora japonica are pruned too late, the wound will not heal easily. If the trunk is too skewed, it should be trimmed again, and the cut should be made at the place where the deviation begins.

Precautions for pruning Sophora japonica

Generally, when pruning Sophora japonica flowers, it is necessary to maintain a relatively reasonable density. A reasonable density can ensure that the Sophora japonica flowers can meet the needs of photosynthesis and achieve the purpose of pruning.

Also, when pruning, pruning needs to be done in a timely manner, but excessive pruning should be avoided.
