The umbrella cover of Sophora japonica can be trimmed into ripples. The method is to leave the reserved branches with short buds at the highest bending point in the first year, the drooping branches of about15cm for pruning in the second year, and the short buds at the highest bending point in the second year. Repeated pruning in this way can form a corrugated umbrella cover. If the drooping branches are slightly longer and shorter, a tower-shaped umbrella surface can be formed in a few years, which is very beautiful when planted alone or in rows.

In the first few years after planting Sophora japonica trees on both sides of the road, scaffolding can be set up on the road surface, and branches on both sides of adjacent paths can be led to the scaffolding to make them grow in the opposite direction. A few years later, when the branches were entangled and fixed together, the scaffolding was removed. At this time, a green corridor will appear on the road, forming a unique landscape. You can also plant a locust tree on both sides of the road entrance and trim it according to the above method, which is also a good shape. In winter, the leaves of Sophora japonica fall off and the staggered branches can be seen more clearly. At this time, it is necessary to trim it carefully. Pruning of Sophora japonica includes summer pruning and winter pruning once a year.
