This morning, now that it's raining, the tree is looking kinda sickly, and droopy. Maybe this killer stuff takes its good ole time. Thanks for the suggestion of the gasoline! Yeah..a fire would do it! But it would burn down not only the fence, but the storage building adjacent to it as well!, not to mention much of the rest of the wooden fence. It has spread so densely between the storage bldg and fence, one can't get to the roots without getting into the thick of it, but perhaps pouring gasoline in the vicinity of the roots will be my next attempt! The neighbors don't even know I went over into their yard and sprayed the whole thing on their side as well as mine.
