The requirement of maintaining peony to the soil is not high. The sandy soil with fertile soil and good drainage performance is the best. It can also be mixed with saprophytic soil, original soil and river sand to make nutritious soil. No matter what kind of soil is selected for cultivation, it should be disinfected. It can be sterilized with carbendazim to reduce the occurrence of diseases and insect pests.
When the temperature rises in spring, the peony can be moved out for cultivation. At this time, it needs to be watered once and then loosened to protect the roots. Especially in spring, before and after sprouting and flowering, the water should be sufficient. In the north, more water can be used when it is dry, but not too much. If it is accumulated for a long time, it will rot. Don't water when the sun is too strong at noon in summer. It's better to do it in the morning and evening. Before and after flowering water can add fertilizer, with fertilizer water to supplement nutrients, bloom more exuberant.
The timing of fertilization is very important for peony. Do not add fertilizer to the new plant within half a year to avoid fertilizer damage. Apply fertilizer again half a year later. Before spring flowering, the temperature just picked up and the leaves began to sprout. At this time, fertilization is used to accumulate nutrients for flowering; after flower withering, another fertilizer is added to supplement the nutrients consumed by flowering, which can also help to differentiate new flower buds; before winter, another fertilizer is added to prepare for overwintering. Generally, it is OK to apply the fertilizer three times a year. The fertilizer should not be too thick.
Sufficient light is very beneficial to the growth of peony. It can supplement nutrients by receiving light every day, but the strong light in summer and the direct sunlight at noon should be avoided. In order to prevent the scorching sun from burning, too much water will be lost.
It can be cured at normal room temperature. The temperature should be controlled at about 25 ℃. Before and after flowering, attention should be paid to ventilation to avoid the influence of high temperature roasting on flowering. Move indoors in winter.
