Common Causes of Goji Berry Leaf Curl
Several factors can lead to leaf curl in goji berry plants. Identifying the cause is essential for effective treatment.
Pest Infestation
Insects such as aphids, spider mites, and whiteflies feed on plant sap, causing leaves to curl and distort. Regular inspection can help detect pests early.
