maple tree wilt
My Japanese red maple in my front yard, which is at least 40 years old, looks terrible and has lost quite a bit of foliage. An arborist said it was wilt and recommended taking it down. Today we noticed that the Norway maple in the back yard also has less foliage than in the past and wonder if it could also have wilt. The question I have for you is: what do we do (other than just take down the trees). Is there some kind of treatment to the soil we should do to keep other trees from being infected?

If the arborist tested (based on laboratory testing) and confirmed verticillium wilt on the Japanese and the Norway maple, there is no soil treatment.
All you can do is plant trees that are not susceptible to this wilt disease
