Does verticillium wilt spread to other trees?
No. verticillium wilt doesn't move tree to tree in a way that makes your other trees a worry. A soil-borne fungus with no cure. Some trees wall it off and live for years; others decline over two or three seasons. Watering and feeding buys more time than any product does.
What to check
One branch or one side wilts while the rest looks healthy. Olive-green streaking in the sapwood under the bark.
Indiana specifics
Common in Indiana maples, and frequently misdiagnosed as drought stress.
