1 Pruning: Peony is an ornamental shrub with 5-8 branches per plant, and the slender and redundant branches are removed. The remaining branches should be evenly distributed and moderately high and low. If the left branches are not arranged in the right order, they should also be removed, and the soil buds (tillering buds) at the root neck should be selected to cultivate branches. Plants for reproduction can completely preserve all their soil buds and branches, and the denser the better, the branches can be cultivated by rameting.
2. De-bud: De-bud can keep branches symmetrical, flowers lush and tidy, and control the number of flowers and the strength of root growth. A book on the study of plant names records: "Those who plant peony must pick its tender buds, and then the essence will gather in the old stems, so there is a saying that peony begins with peony and peony pedicures." The flower buds of peony grow on the terminal buds or on the first lateral buds under the terminal buds. Therefore, the main purpose of peony bud removal is to keep the terminal buds and remove the useless buds on the selected branches. In order to adhere to the plant type, it is necessary to remove the terminal buds of the branches that are too high, leaving their lateral buds to make them bloom; If the terminal bud is not perfect, leave well-developed lateral buds.
In addition to buds, usually between the vernal equinox and Qingming every year, soil buds will not be unearthed prematurely, and in the soil, they can also play the role of transporting and guiding root nutrition; It's too late, the redundant branches of peony grow vigorously, which consumes nutrition and inhibits the normal growth of branches. After the first year of cultivation, peony does not germinate, leaving all branches and buds to grow. In the spring of the following year, when the soil buds are elongated by 5- 150px, the buds are removed, and 5-8 branches or soil buds which are robust or evenly distributed are selected, and all the rest buds are removed with a knife or by hand.
It is best not to let peony blossom within two years after grafting, and pick off the buds as soon as possible when they are found in spring. This should be the case with peony with medicinal special roots. Because a flower needs a lot of nutrition, it affects the growth of plant roots, and some plants only appear in their later years.
