Although peony likes sunshine, it can't be directly exposed to the sun. When the sun is strong in summer, it should be properly shaded, or the leaves of the plant will turn yellow. Potted plants can be placed on the East balcony. If they are placed on the south balcony, shade measures should be taken.
In summer, the peony can be watered once every 5-7 days according to the situation. It is better to water in the morning or evening rather than at noon. In the maintenance process to make the soil in a wet state, basin soil can not be too dry and can not produce water.
After half a month of flowering and withering, compound fertilizer should be applied, mainly phosphate fertilizer, or once fermented farmyard fertilizer. We should pay attention to not too much fertilizer, and do not give it raw fertilizer, it is very bad for its growth.
In summer, when the temperature is relatively high and still very hot, diseases are most likely to occur. The common diseases include brown spot, grey mould, anthrax, etc. After finding that the plants are damaged, the corresponding chemicals should be used for spraying control as soon as possible. In the process of maintenance, we should properly open windows for ventilation, do not let the plants in the too sultry growth environment.
