Citrus leaf drop

Loss of leaf is a significant issue for citrus, slowing the growth of the tree and reducing fruit fill.

Immediate action is needed to redress leaf drop. This includes checking for nutrient imbalances and revising fertilizer programs.

Poor tree vigor and leaf drop are common symptoms of poor calcium availability - defoliation occurs when the leaf Ca levels fall below 3%.

Growers should check using tissue analysis and apply the appropriate calcium nitrate product to the leaf to ensure supplies of the deficient nutrient are not limiting growth.
