Reasons for the wrinkling of new leaves on海棠 and prevention measures

Haitang, as a beautiful ornamental plant, is deeply loved by people. Recently, many netizens have reflected that the new leaves of their Haitang have developed wrinkles, causing concern. This article will provide a detailed analysis of the reasons and prevention measures for the wrinkling of new leaves on Haitang, hoping to bring health to your Haitang trees.

Reasons for the wrinkling of new leaves on Haitang

1. Disease infection

The wrinkling of new leaves on Haitang may be caused by diseases caused by pathogenic bacteria infections, such as Haitang leaf spot and Haitang anthracnose. These diseases can cause symptoms such as spots, curling, and withering of the leaves.

2. Pest infestation

Pest infestation is also one of the reasons for the wrinkling of new leaves on Haitang. Common pests include aphids and red spiders, which extract sap from the Haitang tree, causing the leaves to lose water and wrinkle.

3. Improper water management

Haitang has a high demand for water, but improper water management, such as excessive or insufficient watering, can lead to wrinkling of the new leaves. Poor soil drainage can also cause root diseases, which in turn affect the leaves.

4. Insufficient sunlight

Haitang requires sufficient sunlight. If it is kept in a dark environment for a long time, the leaves may easily develop wrinkles.

5. Temperature changes

Haitang is sensitive to temperature changes, and both high and low temperatures can cause the leaves to wrinkle. The spring, with its large temperature fluctuations, is a high-incidence period for the wrinkling of new leaves.

Prevention measures for the wrinkling of new leaves on Haitang

1. Strengthen disease prevention and control

Regularly inspect the Haitang tree, and if a disease is found, promptly spray fungicides such as carbendazim and mancozeb. It is important to maintain tree hygiene and reduce the multiplication of pathogenic bacteria.

2. Control pest infestation

When pests are found, spray pesticides such as pymetrozine and beta-cypermethrin. During the control process, protect beneficial insects such as bees and ladybugs.

3. Optimize water management

According to the growth needs of Haitang, arrange watering reasonably. During the hot and rainy summer, pay attention to drainage to prevent root diseases. In winter, water less frequently to keep the soil slightly moist.

4. Increase sunlight

Place the Haitang tree in a sunny location to ensure that the leaves receive sufficient sunlight. If space is limited, you can adjust the plant spacing appropriately to increase sunlight.

5. Control temperature

During the period of large temperature changes in spring, make sure to provide a suitable temperature for the Haitang tree. If the temperature is too high, take shading measures; if the temperature is too low, take appropriate warming measures.

There are many reasons for the wrinkling of new leaves on Haitang, including diseases, pests, water management, sunlight, and temperature factors. Understanding the reasons allows us to take corresponding prevention measures to ensure the healthy growth of Haitang trees. It is hoped that this article will be helpful to you.
