New Lilac Hedge Shows Brown Leaf Channels and Wilting: Diagnostic Questions

A spring-planted lilac hedge bloomed well but now exhibits brown dead channels between leaf veins and wilts without watering every 2–3 days. The owner offered photos via email.

Expert Response: Need More Information

Steve requests photos (close-up of affected leaves and overall hedge) and answers to six key questions:

1. When did distress start?
2. Did wilting or leaf channels appear first?
3. Are all plants affected?
4. Any sprays or applications?
5. Watering schedule?
6. Soil drainage?

Photos can be sent to svann@uaex.edu. Accurate diagnosis depends on these details.
