Peony Transplanting Methods
As the king of flowers, the survival rate of peony transplanting directly affects the quality of flowering the following year. Mastering the correct transplanting method can not only protect the fleshy roots but also promote rapid rejuvenation of the plant. This article combines the practical experience of horticultural experts to systematically analyze the key technical points in the entire process of peony transplanting.
Best Peony Transplanting Time and Preparation
Golden Transplanting Period Explained
In the Yellow River Basin, it is recommended to transplant from mid-September to late October, when the daily average temperature of 15-20°C is most conducive to root recovery. In the Yangtze River Basin, it can be postponed to early November, but it should be completed 30 days before frost. In cold northern regions, the operation should be advanced to early September to ensure that the roots form callus tissue before the soil freezes.
Microclimate Adjustment Techniques
Continuous rainy days require postponing transplanting, as积水 can lead to root rot. In case of special weather conditions, temporary shade shelters can be set up to adjust ground temperature and maintain the transplanting area's humidity between 60%-70%.

Substrate Mixing Standards
For ground planting, a ratio of 3:2:1 of garden soil/decayed leaf soil/coarse sand is used, and for pot planting, a special peony substrate is recommended. The pH value should be controlled between 6.5-7.5, with 500g of bone meal added per cubic meter to increase calcium content.
Key Points for Root Treatment
When digging, retain a root ball with a diameter of 30cm, and use a sharp pruning shear to make a flat cut. If a root tumor is found, immediately soak it in a 50% carbendazim solution (800 times dilution) for 15 minutes, then dry and apply wood ash to promote wound healing.
Control of Planting Depth
For grafted seedlings, the base of the grafting scion should be 3-5cm below the ground surface, while for seedlings, the junction of the rootstock and stem should be level with the ground. When filling the soil, compact it in layers, tapping lightly every 10cm to eliminate air pockets, and finally build a 15cm high embankment.
Key Care Measures After Transplanting
Water Management Cycle
The first watering after planting should be thorough, then maintain the soil moist but not waterlogged. In northern regions, water thoroughly before freezing to prevent frost, and immediately water again after spring thawing.
Nutrition Supplement Plan
In March of the following year, apply decomposed cake fertilizer at 200g per plant in a circular groove. During the leaf expansion period, spray 0.2% potassium dihydrogen phosphate on the leaves, with a 10-day interval for three consecutive applications.
By precisely grasping the transplanting timing, combined with scientific root treatment and post-transplant care, the survival rate of peony transplanting can be increased to over 95%. It is recommended to adjust the management details based on the age of the plant, with 3-year-old or older strong seedlings requiring an appropriate increase in the amount of base fertilizer, and newly planted seedlings focusing on anti-freezing and moisture retention to ensure flourishing flowers and leaves after transplanting.
