Solution: should be watered in time.

3. Soil partial alkali causes peony leaves to yellowing: if peony grows in alkaline soil, the leaves will lose green and turn yellow. The symptoms begin between the new leaf veins, while the leaf veins, especially the main vein, remain green, and the phenomenon of yellow and green is very obvious. With the aggravation of the yellowing degree, the leaf veins gradually lost green, then the whole leaf turned white, the leaf margin scorched and the leaf fell off. In severe cases, the top of the branch withered, resulting in the death of the whole plant.

Family culture should pay special attention to the selection of varieties, compared with other varieties, Luoyang Hong, Hu Hong and other varieties of peony are more suitable for pot culture, they have stronger adaptability to the environment. It is suitable to choose peony as rootstock for 3-4 years small peony or ramet seedlings with 3-5 branches. Peony can also be propagated by sowing, but it takes 4-5 years to blossom through sowing and breeding.

Tree peony is a deep-rooted deciduous shrub flower, which likes sunshine, cold tolerance, cool environment rather than high temperature and muggy heat, and is suitable for growing in loose, fertile and well-drained sandy soil (it is appropriate to choose the mixed soil with sand and cake fertilizer. Or culture soil mixed with fully mature barnyard manure, garden soil and coarse sand at the ratio of 1:1:1). Because the root of peony is longer and the plant is larger, it is suitable for planting on the ground. if you want to pot, you should choose a large, permeable tile basin with a depth of more than 30 cm. It is best to use a tile cylinder with a depth of 60-70 cm. The weather in the south is dry and hot, so when it is hot in summer, it is necessary to prevent peony flowers from being exposed to the sun and take timely cooling measures.

In order to make the peony blossom brightly, it can be foliar sprayed 2-3 times with 0.5% ml 1% dihydrogen phosphate solution during flowering.

After the flower fade, pick the flowers and prune in time, cut them according to the natural growth of the tree, and smear the healing and anti-decay film at the trimming mouth to protect the wound and prevent the bacteria from invading and infecting. If the plant is low and the flowers are dense, it should be shorter and heavier in order to inhibit the expansion of branches and the occurrence of root tillers, generally 5-6 branches should be retained per plant.
