Man we are really being hit hard with the ash borer here in Pa. , I have 50 trees affected with the bark falling off in just a small area around me, its a real shame to see them all die , we are also losing are Hemlock trees .On the up side its going to make alot of good firewood but Im afraid its going to go to waste before it can all be used . I've heard it turns punky pretty fast if not cut and put under roof , you guys that have seen all of this going on for a while now what have you found if there left standing , how many years before there soft and punky .
