Troubleshooting Hydrangea 'Limelight' Leaf Curl and Brown Edges

Edna's young 'Limelight' hydrangeas show brown, curling leaves after heavy watering, manure amendment, and daily watering to dilute fertilizer. The likely causes are overwatering, excess fertilizer, or spider mites.

Remedies

Cut watering to once a week (unless rain).
Stop fertilizing.
Treat for spider mites with horticultural soap or miticide (3–5 day intervals).
No further pruning.

New Jersey's naturally acidic soil suits hydrangeas; pH is probably not the issue.
