Why Autumn is one of the best seasons for transplanting peonies

Spring is the season of peony branch

Summer is the dormant period of peony, high temperature season, the above-ground part into the stage of flower bud differentiation and seed development, when the root activity becomes weak, in a semi-dormant state.

After autumn, as the temperature drops, the root system of tree peony begins to grow a second time, it will grow a lot of capillaries, a lot of nutrients in the root bark (mainly secondary phloem) in the accumulation. At this time, the above-ground part of the branches and leaves slowly withered into the dormant period, but the peony root system is still growing to produce new roots. These new fine roots is the most important tree peony transplant, transplant to other places, can adapt to the new environment, quickly take root, so safe over the winter.

What are the benefits of transplanting peony in autumn?

The temperature drops gradually when peony transplanting in autumn, the above-ground branch enters dormancy period, the leaf slowly withers this to the water demand is little, consume nutrient little, this is advantageous to the nutrient balance. Moreover, at this time, the root bark was rich in nutrients, and the ground temperature was relatively high even though the outside temperature had not yet dropped significantly.

The roots of the tree peony were not yet completely dormant, and the root system cut off during transplantation could be healed as soon as possible, and the root system is still growing, constantly producing new roots.

How much do you know about paeonia rockii ? Let me show you some peonies in Gansu

Third, the resistance is strong, drought-resistant, cold-resistant, barren resistance. Paeonia ROCKII is a shade-tolerant plant, which likes to grow in the sparse shrub on shady slope or in the weak light, bare rock and barren soil in the forest under cliff. Its root system can reach more than 10 meters underground, so it has a strong drought resistance, especially the ability to withstand air drying is very strong, in the case of severe drought, it can still grow and bloom; the Soil Adaptation Range is also larger, from slightly acidic to slightly alkaline, can grow normally.

When planting, root system should be evenly distributed in the pit, natural stretch, can not be curled together, fill with live soil will be buried root system first, and then, the seedlings gently shake up. First, the root system should be fully integrated with the soil. Second, the planting depth (the planting depth should be lower than the original root neck about 3 centimeters above the ground) should be determined. First step the first time, then fill the soil and then step the solid soil, when the plant is finished, should be timely watering a pervious, in order to discharge the air in the soil, to prevent the winter cold root injury.

Underground pests are mainly white GRUBS, control methods: 50% phoxim EC 1000-1500 times liquid wash 20-30 cm depth of the root, to 0.25 kg per mu of land is appropriate.
