Pruning method of Osmunda japonica

1, spring

There are two ways of spring: before germination and after germination. Pruning before sprouting should be done before Lagerstroemia indica grows new branches, so as not to interfere with its growth function. Lagerstroemia indica grows faster and germinates faster. In spring, branches sprout and grow leaves everywhere, which destroys the appearance of plants and makes them grow out of order. At this time, pruning can be done by pruning after germination.

In winter, Lagerstroemia indica will go into dormancy, and then prune after dormancy to ensure the shape of Lagerstroemia indica. In the process of pruning Lagerstroemia indica, it is necessary to prune the layered branches to avoid the cross of seedlings after growth, which makes them look more layered, and at the same time, it is necessary to ensure that there are a small number of buds on the trunk.

Pruning in summer and autumn is to lengthen the flowering period of Lagerstroemia indica. Pruning the recently growing branches will only leave a few buds on the branches, which will promote Lagerstroemia indica to grow new branches again and ensure its beauty.
