After planting Sophora japonica seedlings in autumn, there is basically no special management. Before planting the newly planted Sophora japonica seedlings, it should have been trimmed almost. 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 for the pruning method of Sophora japonica in winter, you can operate it next year. Let me introduce it to you in detail.

The growth and dormancy periods 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 1 February to the following year1month. 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, etc., should not be pruned too late, otherwise, a large amount of sap will flow out from the cutting mouth and the plants will be seriously injured, or pruned after bleeding. It is best to cut deciduous trees in summer, and some trees can be cut well in summer, which can save winter cutting. Evergreen trees are suitable for winter cutting and summer cutting.

Dormancy pruning Most of them are carried out in winter dormancy or when the sap just begins to flow and the buds are about to germinate in early spring. Perennial woody flowers, Sophora japonica, which blooms on the branches of the year, such as rose, hibiscus, poinsettia, pomegranate, crape myrtle, chrysanthemum, etc., are replanted during dormancy, which can promote the germination of new shoots to increase flowering. For varieties that bloom in spring, such as Peach, Plum Blossom, Yingchun, etc., the flower buds are mostly formed on the branches of the previous year, so it is not advisable to prune them in winter or before germination in early spring, and they can only be pruned 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 overgrown branches are mainly carried out in the growing season or after flowering of Sophora japonica, which should be carried out in time according to the growth and cultivation requirements of Sophora japonica. Some Sophora japonica generally don't need to be pruned frequently, such as azaleas and camellias. In order to keep the tree symmetrical and beautiful, we should cut off the top of some branches rather than prune them strongly. Lianas only need to cut off the branches of diseases and pests, dense branches and over-old branches, and keep them ventilated and light-permeable. You can visit this website about the planting technology of Sophora japonica/the above summary is very detailed, which can save you a lot of detours in planting, and I hope it can help you.
