Planting peony should choose neutral sandy loam with deep and fertile soil, loose and good drainage, and acidic or cohesive soil is not suitable for planting peony. Choose fermented and decomposed human and animal manure or cake fertilizer as base fertilizer. Don't plant it too deeply, just bury the roots.
Second, the temperature requirements
Peony is not resistant to high temperature, but it is cold-resistant. The growth temperature is kept at 16~20℃, and the suitable flowering temperature is 17 ~ 20℃. When the temperature is higher than 25℃, plants are in a semi-dormant state. The lowest temperature in winter is -30℃, so the northern region should pay attention to cold protection to avoid frostbite of plants.
Three. Lighting requirements
Peony loves to bask in the sun, but is afraid of being exposed to the scorching sun in summer. Potted plants are best placed in a sunny environment during the growing period. In summer, as the temperature rises, plants will enter a semi-dormant state, so we should try our best to shade and keep the environment dry. Give enough light in winter.
Fourth, the watering requirements
Water it once after planting. Peony is a deep-rooted fleshy root, which is drought-resistant and avoids water accumulation. Usually, according to the seasonal climate and the dryness of the basin soil, water flexibly, not too much, and keep the basin soil properly dry.
Five, fertilization requirements
Peony likes fertilizer, and base fertilizer should be applied adequately. After planting for one year, fertilization will be carried out in autumn, mainly with decomposed organic fertilizer. Potting can be combined with watering and applying liquid fertilizer, spraying dilute phosphoric acid water once half a month before flowering, applying compound fertilizer once half a month after flowering and applying compost once before winter, which is beneficial to flowering in the next year.
Six, pruning requirements
After transplanting for two or three years, the stubble should be leveled, that is, all the upper branches should be cut off from the root neck, so as to take root and strengthen seedlings in the coming year and make the branches neat and consistent. Prune branches that are weak and have few branches.
Matters needing attention in peony planting:
1, and the peony planting season is preferably between late September of 10 and early October of 10.
2. Peony needs to loosen soil and weed regularly during cultivation.
3. Pick flowers and trim them in time after the flowers wither, and drop wax to protect the wound and prevent bacterial infection.
