The most commonly used tree type of plum blossom in gardens is "natural happiness". After the survival of plum grafting, when the seedlings grow to more than 1 m, they are cut off at about 65cm. In the second growing season, the first main branch is about 45 cm from the ground, the second main branch is about 10 cm from the ground, and the third main branch is about 10 cm from the ground. These three branches should be evenly distributed in different directions, with the distribution angle of about 120 and the opening angle of 45. When the next winter is completed, the three main branches can be cut short, and the length of the short branches is one third of the length of the branches. Pay attention to the balance of the crown when cutting it short. Strong branches are lightly cut, weak branches are re-cut, and external buds are left after cutting.

Pruning method of plum blossom lateral branches

After the three main branches are selected, a small part of the remaining branches can be reserved as auxiliary branches, and the rest can be thinned out. In the spring of the third year of pruning, the new branches of the extended branches adjacent to the new main branches should be thinned in time, and some robust branches should be kept. Leave some side branches when cutting in winter. These lateral branches should be in the same direction, either clockwise or counterclockwise, and no cross branches can be produced. The reserved lateral branches should be properly chopped and gradually cultivated into flowering branches, and the distance between the flowering branches and the trunk should be not less than 30cm.

Matters needing attention in shaping and pruning Eucommia ulmoides Oliv.

The cultivation of flower branches should pay attention to the combination of medium and long branches and short branches, so that they can bear flower buds to the maximum extent. Pruning of crown after basic cultivation is mainly divided into summer pruning and winter pruning. Summer pruning is usually carried out in June after the flowers are gone, mainly by removing the core from the long branches and pruning the branches that have blossomed, leaving only 3 or 4 buds at the base to make the newly sprouted branches compact.
