The most commonly used Eucommia ulmoides tree type in gardens is "natural happiness".
After the grafted Eucommia ulmoides survived, when the seedlings grew to more than 1 m, they were cut off at about 65 cm.
In the second growing season, the first main branch is about 45 cm away from the ground, the second main branch is about 10 cm above it, and the third main branch is about 10 cm above the second main branch.
These three main branches should be evenly distributed in different directions, with the distribution angle of about 120 and the opening angle of 45.
When laying in the winter of the following year, the three main branches can be cut short, and the length is one-third of the branch length. When cutting short, we should pay attention to the balance of the crown, lightly cut the strong branches, re-cut the weak branches, and cut off the outer buds.
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.
When cutting in winter, some lateral branches should be kept, and the direction of these lateral branches should be the same, either clockwise or counterclockwise, so that no cross branches can be produced.
The reserved lateral branches should be appropriately cut short and gradually cultivated into flowering branches, and the spacing between flowering branches in the trunk should not be less than 30 cm.
Matters needing attention in shaping and pruning Eucommia ulmoides Oliv.
In the process of flower branch culture, attention should be paid to the combination of medium and long branches and short branches to make them bear flower buds to the maximum extent.
Pruning after basic cultivation of crown is mainly divided into summer pruning and winter pruning. Summer pruning is usually carried out in June after the flowers wither, mainly by removing the core from the excessively long branches, shortening the already blossoming branches, and leaving only 3 or 4 buds at the base to make the newly sprouted branches compact.
