Lilac bush disease
What is cause of lilac leaf tips curling up and drying out and dying ? Just noticed now in july.
Buncombe County North Carolina
Thank you for your question. It is difficult to diagnose a problem such as this without photos. It can be a lack of water, or one of the pathogens described in this Extension article. You can either take some photos and send back, or take them plus some leaf samples to your county Extension office where staff can examine them under a microscope. Hope this is helpful. Good luck!
