1、 Conservation environment

1. Soil: it requires loose and fertile soil with high content of organic matter, especially for phosphate fertilizer and potassium fertilizer. Avoid alkaline clay and poor drainage, because it is a fleshy root. If there is water, it is easy to rot

2. Cultivation time: generally suitable for autumn. Generally speaking, it is more suitable for cultivation before and after the Mid Autumn Festival. It is not suitable to plant in spring. It is not easy to plant at this time

3. Watering: in the maintenance process, watering should not be too much, just keep the soil slightly wet. Try not to have excess water in the soil, which is not only unfavorable to its growth, but also affects its flowering

2、 Diseases and insect pests

During maintenance, some diseases and pests such as powdery mildew, red spider and leaf spot disease will occur. We need to make some drug preparations in advance. Generally speaking, some protective fungicides are often sprayed during the season change, which will play a certain role in disease prevention. In addition, the competitiveness of Paeonia lactiflora and weeds is relatively poor. We must pay attention to the surrounding maintenance environment and remove weeds in time, which is also one aspect of preventing diseases and pests
