We had a beautiful willow tree die of this. An elderly neighbor told us to put a black tarp over the entire area after we removed the dying tree for as many days as we could with the sun beating on it. We left it on for several weeks just to make sure. It worked! We planted a new willow about 6 months later and it’s been about 4 years and it’s doing great. I think the heat all day killed it.
