Will Lilac Blight Come Back Next Spring?
Posted: Mon Oct 24, 2011 11:48 am
We have 4 mature lilacs and the leaves have black spots which seem to indicate blight. It is late October in Colorado so we're not too concerned about the rest of this year, but absolutely want the bushes to survive long term.
My wife thinks we should prune all the affected branches (about 50% of them) right now. I'm thinking we just let it go over the winter and see how things come back next year.
So my question: Is there a chance the blight will disappear over the winter and healthy leaves come back? Or is our best bet to hack out everything now?
Thank you.
