After planting Sophora japonica seedlings in autumn, there is basically no special management. The newly planted Sophora japonica seedlings should have been trimmed almost before planting. What needs to be done at this time is to pour enough frozen water to improve the survival rate, and never apply too much nitrogen fertilizer such as urea. Then the pruning method of Sophora japonica in winter can be operated next year. Let me give you a detailed introduction.

The growth period and dormancy period of Sophora japonica are divided into growth period pruning and dormancy period pruning, also known as summer pruning and winter pruning. Summer pruning is from April to August of that year, and winter pruning is from February to 10 of the following year. Different tree species have different biological characteristics, especially different phenology, so the specific pruning time of a tree species should be determined according to its phenology, bleeding, cold and freezing injury. For example, tree species with particularly serious bleeding, such as birch, Acer truncatum, grape, Platanus acerifolia, Sizhaohua, Acer truncatum and so on. Don't prune too late, or a lot of juice will flow out of the cutting mouth, seriously damaging the plant, or pruning after bleeding. Deciduous trees are best cut in summer, and some trees are cut well in summer, which can save cutting in winter. Evergreen trees are suitable for winter cutting and summer cutting.

Dormancy pruning is mostly carried out in winter dormancy or early spring when sap just begins to flow and buds are about to germinate. The perennial woody flower, Sophora japonica, bloomed on the branches of that year, such as rose, hibiscus, poinsettia, pomegranate, crape myrtle and chrysanthemum. Replanting during dormancy can promote the germination of new shoots and increase flowering. For varieties that bloom in spring, such as peach, plum blossom and Yingchun. Flower buds are mostly formed on the branches of the previous year, so they should not be pruned before germination in winter or early spring, but only after flowering to promote the germination of new shoots and form the flower branches of the next year.

Pruning in growing season. Pruning, coring, leaf picking and cutting off dead branches, diseased branches and excessive branches are mainly carried out in the growing season or after flowering of Sophora japonica, and should be carried out in time according to the growth and cultivation requirements of Sophora japonica. Some Sophora japonica generally do not need to be pruned frequently, such as azaleas and camellias. In order to keep the symmetry and beauty of the tree, we should cut off the tops of some branches instead of pruning them vigorously. Lianas only need to cut off branches of diseases and insect pests, dense branches and over-aged branches, and keep ventilation and light transmission. You can look at this website about the planting technology of Sophora japonica/the summary above is very detailed, which can save you a lot of detours in planting, hoping to help you.
