What is the curling of peony leaves?

Peony is a very common flower in China, peony not only has a very high ornamental value, but also can be eaten and used as medicine. It is very popular in our country, but when planting peonies, there are still many problems, which lead to the decline of the planting efficiency of peonies. And the peony leaf curling is one of them, so what is the peony leaf curling? Let's take a look at it.

1. Root system damage

Peony flowers need our attention when transplanting. If the root system of peony is seriously damaged or the transplanting time is too late, then the restoration of the root of peony is blocked and can not grow new roots. In spring, the supply of nutrients needed for the growth of peonies will be seriously affected. If the nutrition is insufficient, then the peony plant will not be able to develop normally. At the same time, the leaves will also appear all kinds of bad phenomena such as curling, yellow leaves and so on because of the damage of root system.

2. Temperature discomfort

Peony likes to grow in a warm environment, and its low temperature tolerance is very poor. If the peony flower is exposed to low temperature for a long time, the leaves are extremely vulnerable to frostbite, and the roots are also prone to frostbite. After the root is frozen, the absorption of water and nutrients is blocked, resulting in leaf curling. Therefore, when we plant peony, we must pay attention to control the temperature around the peony plant. If the temperature is too low to cause the leaves to curl, then it should be heated in time, if it gets better slowly, it means that the situation is good. If it doesn't get better, check to see if the roots are rotten, cut them off and replant them.

3. Excessive illumination

Although peony flowers have certain requirements for light in the process of growth. But we should also pay attention to the light intensity and time, if in summer and other strong light environment for a long time, then peony leaves are extremely vulnerable to frostbite. And the effect of water transpiration will also be strengthened, resulting in the loss of water in leaves. Therefore, after the leaves are burned, we should pay attention to shading and shading, so that the leaves slowly return to normal. Wait until it returns to normal, and then put the plant in the sun, and then shade the sun when the light is too strong, such as noon and summer, to prevent the peony plant from being exposed to the sun.

4. Reasons for water and fertilizer

The curling of peony leaves may be caused by improper water management. Peony words have a large demand for fertilizer, if there is a shortage of water and fertilizer, it will lead to malnutrition and lack of water in peony flowers, resulting in the phenomenon of curling. However, we should also pay attention to control the amount of water, generally before the flower topdressing after a thorough watering, and then to see dry see wet as the principle. If too much watering is easy to cause rotten roots and dead seedlings, you should also pay more attention to topdressing. We should not only control the dosage, but also pay attention to the position of topdressing, so as to avoid burning seedlings caused by too much fertilizer. Foliar fertilizer can be properly sprayed to improve the growth ability of leaves and reduce the phenomenon of curling.

The above is a brief introduction to how the leaves of peonies are rolled up. That's all for today's introduction. This article is for reference only. I hope it can help you all.
