1、 Reasonable shading

Although peony likes sunshine, it cannot be directly exposed to the hot sun. In summer, when the sun is strong, it should be shaded reasonably, otherwise the plant leaves will turn yellow. Potted plants can be placed on the balcony near the East. If they are placed on the balcony near the south, shading measures should also be taken

2、 Proper watering

In summer, the peony can be watered once every 5-7 days according to the situation. It should be avoided at noon. It is best to water in the morning or evening. During the maintenance process, the soil shall be kept in a wet state, and the basin soil shall not be too dry or produce ponding

3、 Scientific fertilization

After half a month of flower senescence, compound fertilizer should be applied once, mainly phosphate fertilizer, or once fermented farmyard fertilizer. It should be noted that the amount of fertilizer should not be too large, and do not apply raw fertilizer to it, which is very unfavorable to its growth

4、 Disease control

In summer, when the temperature is relatively high and muggy, diseases are most likely to occur. Common diseases include brown spot, gray mold, anthrax and so on. After the plant is found to be damaged, it should be sprayed with corresponding chemicals as soon as possible. In the process of maintenance, windows should be properly opened for ventilation, and the plants should not be in a too muggy growth environment
