What to Do When Grape Leaves Turn Yellow
Grape leaves that turn yellow and dry need shade, and it is important to do a good job of cooling and moisturizing. In the summer when there is a lot of rain, soil drainage should be done well to prevent water accumulation. It is necessary to supplement grape nutrients in a timely manner; after diluting and applying fertilizers, root burns may occur. For leaves infected with bacteria, they must be removed promptly, and insecticides should be sprayed to control the situation.
Shading and Watering
In the summer, as temperatures rise and the environment becomes dry, strong sunlight can cause grape leaves to turn yellow and dry. It is necessary to do a good job of shading protection, as strong sunlight can cause leaf burns. When the environment is dry, you can sprinkle water on the air and leaf surfaces to moisturize and promote continuous growth of the grapes.
Drainage and Ventilation
Grapes are not tolerant of waterlogging. With more rain in the summer, the presence of water can lead to root rot. It is necessary to choose loose and fertile soil, add loam and sand to improve soil permeability, and promptly repair, ventilate, and exchange air to promote grape root absorption. Drainage work should be done well during the rainy season, and the leaves will gradually recover.
Proper Fertilization
Adequate nutrition can promote the continuous growth of grapes. During the grape growing period, it is common to use fertilizer solutions to provide sufficient nutrients to supplement the grapes. During the fertilization process, fertilizers should be diluted and used; high concentrations can cause root burns. It is necessary to change the yellowing phenomenon of the leaves promptly, and water the grape roots to promote absorption.
Infection by Pathogens
If the grape leaves turn yellow from the position of the roots and stems, it may be caused by bacterial infection, with the leaves gradually developing yellow spots. It is necessary to control and prevent the situation in a timely manner to avoid leaf drying. Damaged leaves should be removed promptly to reduce the breeding of diseases and pests. Spraying insecticides in a timely manner can result in effective treatment.
