I have a bigtooth maple That was planted last summer. It got overwatered last summer before realizing how poorly draining our clay soil is. it didn’t die completely, so I left it through winter. This spring, it leafed out and got loaded with seeds. Suddenly the whole thing wilted and the leaves got crispy. when Scratching the bark, it’s still green underneath. However, when I cit Off a branch, I found Discolored wood. Now I’m suspicious of verticillium wilt. I suspect It prob came on the tree if so. Are there any other conditions that would cause this coloring in the sapwood? I’m in the front range I’d Colorado, zone 5. Any help is appreciated.
