Do you know these? Let's take a look at the introduction of the green plant and flower aspect about "what to do if the leaves of the red maple wither" and the analysis of the reasons for the withering of the red maple leaves!
There are many reasons for the withering of red maple leaves. 1. Disease infection: If it is caused by disease infection, you can cut off the dried branches and leaves, and spray carbendazim or chlorothalonil solution. 2. Exposure to strong sunlight: If it is caused by exposure to strong sunlight, you can遮光 appropriately and avoid direct strong sunlight. 3. Lack of water: If it is caused by insufficient water, water should be irrigated in time. 4. Insufficient nutrition: If it is caused by insufficient nutrition, you can apply basic fertilizer in advance and top-dress with thin fertilizer according to different growth stages.
I. Disease Infection
Reason: First, determine if the red maple leaves are infected with a disease. Improper management of red maple may lead to leaf blight, causing a large number of leaves to wither and fall, affecting the normal growth of the red maple tree.
Treatment method: Strengthen daily management. If the red maple tree is infected with a disease, you need to cut off the dried branches and leaves and dispose of them together, spray carbendazim solution or chlorothalonil solution multiple times continuously to treat the disease.
II. Exposure to Strong Sunlight
Reason: As temperatures rise and sunlight intensifies in the hot summer, the leaves of red maple may be sunburned, causing a large amount of water loss and leading to晒伤 and withering.
Treatment method: Choose a suitable planting location for red maple, provide appropriate shading, and avoid direct strong sunlight to maintain a ventilated growing environment.
III. Lack of Water
Reason: Red maple needs water during cultivation and management. If water is insufficient for a long time, it will lead to soil dryness, preventing the roots from absorbing water, resulting in withered leaves.
Treatment method: Water the red maple tree in time to allow water to penetrate the soil, enabling the roots to absorb sufficient water to supply to the leaves.
IV. Insufficient Nutrition
Reason: Red maple trees should ensure sufficient nutrition during the growing period. If fertilization is insufficient and nutrients are lacking, it can lead to withered leaves.
Solution: Apply basic fertilizer in advance and top-dress with thin fertilizer according to different growth stages.
