Reasons and Solutions for the Drying of Watermelon Leaves
The drying of watermelon leaves may be due to excessive application of foliar fertilizer, excessive light in the plant's care environment, or infection with diseases and pests. If the drying is due to excessive fertilization, it is necessary to stop fertilizing immediately and dilute the fertilizer with water. If it is due to excessive light, shading is required to reduce sunlight. If it is due to infection with diseases and pests, corresponding pesticides should be used for spraying treatment.
What Causes the Drying of Watermelon Leaves
The drying of watermelon leaves may be due to improper care, such as excessive application of foliar fertilizer, too much light in the plant's care environment, or leaf drying caused by infection with diseases and pests.
Some dried leaves of watermelon may fall off easily and can be saved, while others cannot, depending on the specific situation. If the number of dried leaves is small, they can be saved, but if it is very severe, they cannot.
Reasons for the Falling of Dried Watermelon Leaves
1. Excessive Fertilization: Although watermelon requires sufficient nutrients during growth, excessive nutrients can cause plant burn, leading to leaf drying and falling.
2. Excessive Sunlight: If watermelon leaves are exposed to strong sunlight in summer, they can be sunburned, leading to leaf drying and falling.
3. Infection with Diseases and Pests: If the care environment is poorly ventilated during the growth of watermelon, it can easily trigger various diseases and pests, which cause nutrient loss in the plant and lead to leaf drying and falling.
Solutions for the Drying of Watermelon Leaves
1. If the drying is due to excessive fertilization, stop fertilizing immediately and water the plant with an appropriate amount of water to dilute the fertilizer.
2. If the drying is due to excessive sunlight, reduce the light by taking shading measures or move the plant to a place with diffused light for care.
3. If the drying is due to infection with diseases and pests, use corresponding pesticides for spraying treatment and move the plant to a well-ventilated area for care.
Remedies for the Falling of Watermelon Leaves
The drying and falling of watermelon leaves require improved greenhouse ventilation, reducing the relative humidity to below 70%, applying phosphorus and potassium fertilizers and organic fertilizers, reducing the application of nitrogen fertilizers, and using chemicals like benzalkonium chloride or validamycin for spraying, which are effective.
Fertilizing for the Falling of Watermelon Leaves
Generally, when watermelon leaves dry and fall, it is possible to control the problem by spraying with chemicals like bromothalin or isoprothiol, and also by supplementing with carbon dioxide gas fertilizers.
