Pointers from Minnesota tree experts
Today, Agweek published an article titled "Own an ash tree? Follow these tips." It's a list of practical pointers that may help ash tree owners as they decide how to deal with the emerald ash borer in their landscape.
The Minnesota experts don't recommend treating an ash tree with preventative chemicals until the borer has been identified within 15 miles. They also caution that tree owners should beware of scam artists who want to sell expensive, useless treatments.
