Dell writes that his vinegar potion only kills the tops of undesired plants... On this, long ago in our "Kill-raspberries-et-al.-that-competes-against-spruce-&-fir" course in Forest Management @ UNB, Canada, we were instilled with the notion that "weeds" are best dealt with near the end of the growing season when they have used up all their resources. Perhaps timing is a concern here. J.
