It all started about 5 years ago when we brought willow home from a friend with strange looking black nodules on it.
I had never seen it before and did not make much of it. It looked quite harmless, a little like a gall.
That next year I noticed some on our own willow as well for the first time.
This has since spread to a few willow beds and is increasing with each year.
In this video I talk about it, show you what it looks like and what I am doing about it….
