Pruning and shaping peony flowers: Peony pruning and shaping can generally be carried out after the flowers wither. One is to remove too many dense new buds; Secondly, for varieties with vigorous growth and stout branches after 2-3 years of cultivation, the excessively long branches are generally cut off, and 3-5 full and evenly distributed branches are left for each plant, 2 external flower buds are left for each branch, and the rest are all cut off. If there are too few branches, the flowers will be sparse, too many branches and too dense flower buds will affect flowering. Third, for varieties with weak growth and poor branching ability, only the weak branches are cut off and the strong branches are kept; Fourth, in spring, the sprouting tillers of the root neck should be pulled out in time to concentrate nutrients on the branches and promote growth and flowering.
Remove peony leaves in autumn and winter, because peony diseases are spread through leaves. Therefore, the leaves falling from the base of peony stems must be thoroughly cleaned in autumn and winter. It can obviously reduce the occurrence of diseases in the coming year. The removed fallen leaves should be buried deep or burned, buried deep below the plough layer, and the remaining fallen leaves should be burned thoroughly and cleanly, and buried deep after burning.
Peony flower branches are fragile and easy to break. When a flower first blooms, because the flower head is heavy, the branches often bend and are easily blown off by the wind. Therefore, the pillars should be set up in time to make the flowers stretch, and the pillars can be painted green to add beauty.
