Why are the leaves of the peony plant curling?

The peony is a very common flower in China. Peonies not only have very high ornamental value, but can also be eaten and used as medicine. They are very popular in China, but when growing peonies, many problems still tend to arise, causing a decline in peony growing returns. Curling peony leaves are one of them, so what is going on with curling peony leaves? Let's take a look below!

1. Root damage

We need to pay special attention to peonies when transplanting them. If the peony roots are severely damaged during transplanting, or if the transplanting time is too late, then the recovery of the peony roots will be hindered and they will be unable to grow new roots. And in spring, the nutrient supply needed for peony growth will be seriously affected. If nutrients are insufficient, then the peony plant naturally cannot develop normally. At the same time, the leaves will also show various adverse symptoms such as curling and yellowing due to root damage.

2. Unsuitable temperature

Peonies like to grow in a warm environment, and their tolerance to low temperatures is very poor. If peonies are kept in a low-temperature environment for a long time, the leaves are very easily frostbitten, and the roots are also prone to cold damage. After the roots suffer cold damage, the absorption of water and nutrients is hindered, thereby causing the leaves to curl. Therefore, when growing peonies, we must be sure to control the temperature around the peony plant well. If the leaves curl because the temperature is too low, then increase the temperature in time. If it gradually improves, that means the condition is good. If it does not improve, then check whether the roots are rotten, cut off the rotten roots, and then replant.

3. Excessive light

Although peonies do have certain light requirements during growth, we also need to pay attention to light intensity and duration. If they are exposed to strong light for too long, such as in summer, then peony leaves are very easily frostbitten. Moreover, water transpiration will also increase, causing the leaves to lose water and curl. Therefore, after the leaves are scorched, be careful to provide shade and block the light, and let the leaves slowly return to normal. After they return to normal, place the plant in the sunlight again, and then provide shade when the light is too strong, such as at noon or in summer, to prevent the peony plant from being exposed to the blazing sun.

4. Water and fertilizer reasons

Curling peony leaves may be caused by improper water management. Peonies have a relatively large demand for fertilizer. If water and fertilizer are insufficient, it will cause malnutrition and lack of water in the peony, resulting in curling. However, be careful to control the amount of watering well. Generally, water thoroughly once after topdressing before flowering, and then follow the principle of watering when dry and stopping when wet. If too much water is given, it can easily cause root rot and dead seedlings, and topdressing also requires a lot of attention. You should control the amount well and also pay attention to the topdressing position, to avoid excessive fertilizer causing seedling burn. You can appropriately spray foliar fertilizer to improve the leaves' growth ability and reduce curling.
