How can I help? I have a beautiful sugar maple that I think has verticillium wilt.
Hi, I wrote last year about my sugar maple and it still has white plack type spots on it's bark. I think it has verticiullium wilt. Is there anything I can do to help this tree, slow down the process? I do not want to lose this tree, it provides lots of shade and is beautiful. Thanks, Michelle
