Peony is a very popular flower, but if it is not repotted for a long time, it will adversely affect the growth and development of the peony. When is the best time to repot? How to choose the right potting soil and pot? How to prune and fertilize? These questions require us to conduct in-depth understanding and discussion.
I. When is the best time to repot?
During the growth and development of peonies, it is generally necessary to repot every two years. The best time for repotting is in autumn or spring, which can avoid damage to the peony from high and low temperatures.
II. Choose the right potting soil
Peonies like loose and well-aerated soil, so when buying potting soil, choose soil with good drainage and air permeability, and mix in an appropriate amount of well-rotted organic fertilizer.
III. Select a suitable pot
When selecting a pot, choose a ceramic or plastic pot that is moderately sized, has a hard texture, and has good air permeability. Also, make sure the bottom of the pot has drainage holes to avoid water accumulation.
IV. Pruning
Before repotting, it is necessary to prune the peony by removing withered, diseased or pest-infested, and disorderly growing branches and leaves, retaining the main trunk and main branches.
V. Pruning the roots
Take the peony out of the potting soil and prune the roots. Generally, for peonies with vigorous metabolism, the roots need to be pruned to 1/3 to 1/2 of their original length.
VI. Replace with new potting soil
When repotting, place an appropriate amount of bottom soil and fertilizer in the new pot, place the peony in the pot, and add new potting soil. Finally, gently pat it down and water thoroughly.
VII. Fertilization
Within a few days after repotting, it is necessary to apply fertilizers such as monopotassium phosphate to promote the healthy growth of the peony.
VIII. Avoid direct sunlight
For a few days after repotting, the peony needs to be protected from direct sunlight to prevent leaf scorch.
IX. Maintain proper humidity
Peonies prefer an environment with suitable humidity, so after repotting, it is necessary to replenish water in time and pay attention to maintaining the moisture of the potting soil.
X. Avoid moving
For a few days after repotting, it is best not to move the peony to avoid excessive shaking and damage to the leaves.
XI. Regular pruning
During the normal maintenance process, it is necessary to prune the peony regularly, removing withered, diseased or pest-infested, and disorderly growing branches and leaves.
XII. Moderate fertilization
During the growth and development of peonies, it is necessary to fertilize moderately and make reasonable adjustments according to seasonal changes.
XIII. Proper watering
Peonies need an appropriate amount of water, but not too much. When watering, it is necessary to keep the potting soil moist and avoid water accumulation.
XIV. Prevent pests and diseases
During the maintenance process, it is necessary to pay attention to preventing pests and diseases of peonies, clean up dead leaves and weeds in time, and use appropriate pesticides and insecticides for control.

Through the detailed introduction of repotting peonies, we can find that many aspects need to be paid attention to during the repotting process, including the time of repotting, choosing potting soil, selecting a pot, pruning, fertilizing, etc. Only by doing a good job in these aspects can we enable the peony to grow healthily and bloom beautifully.
