1, main branch pruning: Eucommia ulmoides has some strong main branches on the whole tree. For these main branches, a lot of pruning is needed. Only by ensuring the intensity of pruning can we promote the growth of new shoots, synthesize more nutrients and make these strong main branches stronger. For some old branches, they have no flowering ability or a small number of flowers. These branches can be cut off, leaving some new branches that have just sprouted, and their vitality is relatively strong.

2. Side branch pruning: In addition to the strong main branch, there are many side branches. Strong side branches can be lightly sheared, so that they can still exert their growth ability, and weak side branches can be removed. Maintaining the balance between the main branches and the lateral branches, thus promoting the germination of more strong branches, is more effective for the whole tree.

3, plastic pruning: Eucommia ulmoides is an ornamental tree, to ensure good aesthetics, if not trimmed in time, it will lead to messy branches, regularly cut off old and weak branches, pests and diseases, disabled branches, dead branches, for cross branches, too dense branches, but also trim a part. According to the overall state of the tree, create a shape suitable for elm plum.
