Deficiency of Fertilizer: Yellowing of grape leaves due to lack of fertilizer can lead to withered leaves if not fertilized in time, as they lack nutrients. However, excessive fertilizing can cause fertilizer damage and also harm the plant's growth. Therefore, it is better to apply fertilizers moderately.
Disease: Yellowing of grape leaves may be caused by fungal diseases, with small yellow spots appearing on the leaves, followed by disease spots, causing the plant to dry up and die. It is necessary to spray chemicals for prevention and control.
