White lilac problem
We live in Chicagoland. For the first time we observe this lilac disease.
The first picture shows three white lilac trees.
The second picture shows two leaves, damaged by fungus or virus (?).
How do I get rid of this, please?
It could be blight. There's a bit of advice here.
This looks like leaf blight, have you had a lot to wet weather? too much damp can be the cause. when you have some dry sunny weather, prune out the effected branches and destroy them.
The tree should come back and be ok.
Hope this helps
