Answer: Comrade Ma: Hello, peony fertilizer needs to be relatively large, so it is necessary to apply sufficient fertilizer. Base fertilizer to soil fertilizer is appropriate, each hole should be 50 kg-70 kg fertilizer. Fertilizer should be applied to the bottom of the hole. The method is: dig a hole first, the size of the hole to determine the number of fertilizers, Xing should be between 60 cm-70 cm. The fertilizer is applied to the bottom layer of the hole, and then covered with a layer of moist fertilizer soil, which is 15 cm-20 cm away from the ground to facilitate seedling planting. After planting, topdressing is generally required three times a year: the first time is pre-flowering fertilizer, which is carried out in late March, and decomposed human dung or cake fertilizer is applied. The second time is fertilizer after flowering, and the first time is phosphate fertilizer and cake fertilizer. The third time is defoliation fertilizer, which is carried out before freezing in early November to protect and improve soil fertility and ensure its safe winter. Each fertilization should be combined with watering. The above is for reference only.
