Hi Dianne,

Sounds like the lilacs have been an important part of your property for many years. While it is hard to say for certain, there are a few things that could be causing your leaves to brown and dry. First of all, it could actually be two different issues. Given last year was hot and dry, your lilacs could have been dealing with drought stress. This year, it could be a fungal or bacteria disease issue that is causing your lilacs to have issues.

If it is a disease issue like blight, it’s actually common to occur when spring (not summer) weather is cool and wet. If that was the case during the spring each of the last two years, that might be the cause. If it is restricted to just certain areas of your lilacs, you can pruning affected areas, which will promote new growth. Just be sure to disinfect any tools after each use.

One other cause could be nutrient deficiencies. If you have not added fertilizer in recent times, you might want to get a soil test to see where any deficiencies might be and amend your soil accordingly.

Hope this helps!
