Emerald Ash Borer

I have heard some customers ask if they should be treating their ash trees yet for EAB.  The multi-state publication put out by universities from Ohio to Minnesota says that one should wait until the insect has been found within 10 to 15 miles.  I fully agree with that.  We should be saving our money for when the insect is here and doing damage.

  1. EAB is tough to diagnose. In the first few years it will look a little thin in the crown, extra suckers and eventually some dieback in the tips. Sounds like every other stress an Ash can suffer from. Right now there has not been any found in the Rochester area.
