If potted peony is allowed to grow naturally, it will not only be disordered in plant shape, but also waste nutrients and reduce flowering, so it needs reasonable pruning. When sprouting in early spring, the sprouting tillers (commonly known as soil buds) sprouting on the root neck should be pulled out in time, while the upper 2 ~ 3 buds on the growing branches should be kept, and the rest buds should be pulled out. Cut off the residual flowers and pedicels in time after the flowers wither to prevent them from fruiting and reduce nutrient consumption, which is beneficial to the differentiation of flower buds in the current year; Two lateral buds are reserved in the lower part of each branch, and all the upper branch buds are cut off. In autumn and winter, overlapping branches, internal branches, cross branches, pest branches, etc. It should be thinned and twigs should be cut short to stimulate their growth. In autumn, we should also pay attention to eliminating the extra buds at the lower part of the branches. Through pruning year after year, plants become beautiful, vibrant and colorful.
