Our Willow is suffering from something, and I am wondering what ails it. I don't know if these photos show it sufficiently. It looked the same way at the beginning of last season, but improved in the summer. Too much rain?

Reminds me of Verticillium wilt. Easiest way to confirm is to cut off an affected branch and look for the black and brown streaking.

I imagine it would be near impossible to get to much rain for a Salix, they grow in the side of lakes, streams, ect.

Thank you HydroPinke, I will cut a branch and check for the signs.

No sings of Verticillium wilt when I cut a branch.
