Willow tree dropping leaves
Our willow tree has been dropping a lot of yellowing leaves over the last couple of weeks, and I assumed it was due to the dry spell, but today I noticed that the fallen leaves have brown spots on them.
I'm not sure if the spots are due to a disease or if that is how leaves that dry up and die look.
We removed a huge competing tree in the winter and the willow leafed up beautifully in the spring, so we're sad that it now looks ill.
I've attached photos of the tree and some dropped leaves. Any advice gratefully received.
