How to prune the hairy ash

Pruning principles for hairy ash

Generally, when pruning the hairy ash, the shape of the tree to be pruned needs to be determined based on the different ornamental qualities of the plant.

If the hairy elm is sown in spring, the seedlings will grow to about 30cm in June or July. At this time, the plant begins to grow side branches, and it is necessary to remove buds and branches in time to promote the growth of seedlings.

Secondly, because the hairy elm is generally used for landscaping, one way is to cultivate it as a street tree, and the other is to grow it as a landscape tree or a garden shade tree. This requires a different pruning approach.

Pruning methods for different uses of tamarisk trees

Generally, when the tomentosa tree is grown as a street tree, the height of the trunk should not be less than 2.8 meters. When it is grown as a garden shade tree or landscape tree, the height of the trunk can be 2.2 meters.

After the trunk is fixed, 3 to 5 new branches can be selected from the trunk of the hairy elm as main branches for cultivation. The main branches should be staggered up and down and each occupy one side. During winter pruning, the main branches should be shortened, generally keeping 1 meter. In the second year, side branches should be selected on the main branches and shortened during winter pruning, keeping the length of the cut to about 1.5 meters. The branches grown in the second year can be used as secondary side branches. In this way, the basic tree shape of the hairy ash is formed. After that, you can promptly prune drooping branches, diseased and insect-infested branches, crossing branches and redundant branches. Since the hairy elm has a strong ability to sprout suckers, the suckers on the main trunk should be removed in time.

When planting tamarisk trees in landscaping, it is best to choose early spring or late autumn, and the plants usually have soil balls on them. After transplanting, the seedlings should be pruned, the secondary side branches should be retained, and they should be shortened.
