Weird Bump....
I was driving down the road the other day out in the middle of nowhere. Low and behold, a leaning oak (or should I say the remainder of an oak), leaning out from under the lines had just been clearance pruned. And wrapped around the leader under the lines and screwed down was a black plastic sheet. Obviously preventing light to get to the leader so it would not sprout growth again under the line. Had to be Asplundh, Trees Inc, or one of the subs up here done it. I wish I had a camera in the van. This thread came to mind right up. Odd. Anyone else see this practice? It looked like the product was made for the tree business, it was that clean of an install.
