When is Wei Zihua topping?

Topping Osmunda japonica should be carried out in the growing season, and it can be done when the seedlings grow to the required height in spring. The method is simple, just cut it from the desired height. Generally, it is necessary to top it twice and do it again when it reaches a certain height, so that the height can be basically controlled and the lateral branches can germinate and grow better. Usually, it is found that long branches should be cut off in time to reduce nutrient consumption, so that later branches will be more robust and bloom more.
