Troubleshooting Leaf Curl and Scorch on Young Crape Myrtles

Assessing the Damage

Two-year-old white crape myrtles on the Outer Banks show curling, dry brown leaf margins despite no visible insects or mildew. A dry spring and unusual February cold may have stressed the trees, but root issues are often the underlying cause.

Professional Evaluation Recommended

Hire an ISA-certified arborist to inspect the root system for girdling roots, planting depth errors, or soil compaction. These structural problems restrict water uptake, causing symptoms that mimic leaf curl disease or scorch.

Immediate Care

Water deeply during dry spells, mulch to conserve moisture, and avoid fertilizing until the cause is diagnosed. Proper diagnosis ensures targeted treatment and the best chance of recovery.
