April 26, 2016 - I was always partial to White Ash
trees. Had a real nice grove of them around a picnic area back in
Then came warnings of the Emerald Ash Borer (EAB)
invasion. What began as a foreign import soon invaded
Pennsylvania from Ohio.
The 44-year-old tree in the photo above was the only
shade tree in that front yard. Gone!
Originally, the insect only appeared in a handful of
counties near Pittsburgh. But the list continued to grow as it left
thousands of dead Ash trees in its wake. It's probably in every
Pennsylvania county by now.
There are chemical treatments available to protect
especially valuable trees, but for most homeowners it would be like
swimming upstream with the ongoing cost of chemical treatments. Plus
one of the pesticides has been linked to the honey bee decline.
It probably makes more sense to remove vulnerable Ash
trees and replant with a variety of tree that isn't at death's doorway.
Be very cautious when removing dead trees due to the possibility of
brittle branches falling.
was first discovered in the US near Detroit in 2002. By 2010 it had been detected in 13 U.S. states
and 2 Canadian provinces. It's destructive spread continues!
