The base fertilizer for cultivating peony must be sufficient, and the base fertilizer can be compost, cake fertilizer or manure. Usually, it is better to apply fertilizer three times a year, that is, spray phosphate fertilizer and fertilizer water of Huazhuangdiling once half a month before flowering. Apply compound fertilizer once half a month after flowering and compost once before winter to ensure the next year's flowering. Spraying a new type of high-fat film greatly improves the effective component rate of pesticides.

The nutrients in the basin are limited, and only timely topdressing can ensure the normal growth and development of peony. After soaking fermented sesame, peanut and bean cake, topdressing can be started from the following spring. Water should be added when applying, and water should be applied 1 ~ 2 times a week during the growth period. As the saying goes, "Peony should be dry but not wet". Peony is a deep-rooted fleshy root, afraid of long-term water accumulation. Don't water too much at ordinary times, but dry it.

Pruning method of peony

Prune the residual flowers after the peony flowers wither. In order to make the crown low and the flowers dense, it can be pruned before July to avoid too dense branches affecting flowering. It is advisable to leave 5 ~ 6 main branches per plant. In order to improve the ventilation and light transmission conditions of peony and concentrate nutrients, it is also necessary to carry out plastic pruning after falling leaves in autumn and winter. Cut off too dense branches such as parallel mouth, cross mouth, introversion and insect-proof mouth to keep the plant in a beautiful shape.

Pruning potted peony can be divided into two types: winter pruning and spring and summer pruning. In spring, potted peony should choose branches and buds, erase the redundant buds sprouted in rhizosphere, cut off internal branches, transverse branches and heavy branches, and sparse weak branches and redundant branches to ensure beautiful plant shape, ventilation and light transmission. You can cut off the residual flowers in summer and today, and you can cut off the dead branches and long branches after the leaves fall in late autumn.
