Hongyundang is a kind of tufted herb, which generally does not need much pruning in the growth process. In the family, if it is pruned, there will be some old leaves at the bottom, sometimes they will turn yellow, dry tip, scorched edge and so on. It is OK to prune the remaining leaves at the bottom, and other parts are generally not pruned.
If you buy Hongyun this year and want to continue breeding after the bottom of the tiller buds sprout, you need to cut off the old plants that have already withered and blossomed from the roots, and make room for the new tiller buds to grow into seedlings. At this time, you need to start pruning from the base, and use a sharp knife or scissors to trim it.
