Peony is one of the famous traditional flowers in China, beautiful and noble. In spring, the peony blossoms, with a riot of colors, attracting countless tourists. However, when winter comes, we find that the leaves on the peony tree turn yellow and fall one by one, even exposing the branches. Does this mean the peony plant is sick? This article will explore with you the reasons why peonies lose their leaves in winter and the protective measures.
Why do peony trees lose their leaves in winter?
Peonies are deciduous shrubs or small trees, so they naturally shed their leaves when the weather gets cold in winter. This is no different from other deciduous plants.
Is peony leaf fall related to pests and diseases?
Some peony pests and diseases can also cause leaf drop. For example, pests like spiders, aphids, and mites suck the sap from peony leaves, causing the plant to gradually wilt and the leaves to fall off.
What causes peony leaves to turn yellow?
There are two possible reasons for yellowing peony leaves. One is that the peony receives inappropriate light or excessive sunlight exposure, causing the leaves to become dry, gradually die, and then fall off the tree. Another reason is that the soil where the plant is located is too acidic, leading to slow growth and easy leaf drop.
How to effectively prevent peony leaf fall?
1. Provide adequate water and nutrients for peonies to maintain their healthy growth.
2. Timely pest control measures for peony plants are necessary. For larger pest problems, pesticides can be used.
3. Adjust the soil pH to make it healthier. Ensure sufficient organic matter content in the soil, which can be achieved by applying organic fertilizer or manually improving the soil.
4. Place mulch (such as leaves, grass, etc.) around the crown to reduce air circulation and keep the tree warm.
How to judge if the peony's leaf fall is normal?
If the peony retains its vitality while shedding leaves, such as plump buds, few withered parts, and good healing of wounds on the trunk, there is no need to worry too much about the leaf fall. If there is a large amount of disease and death, it should be treated in a timely manner.
How to manage peonies in winter?

3. Prevent excessive moisture. Do not pile too much snow around the plant.
How should peony winter pruning be carried out?
Winter pruning can help peonies maintain a healthy growth state and enhance their cold tolerance in winter.

How to correctly transplant peonies?
1. Transplant in spring or autumn, preferably on a windless or cloudy day.
