This is not an answer but another conundrum: The previous tenants at our house clearly never set foot outside, as there is old kudzu growth everywhere. The kudzu in the front has an impressive, tree-like root system, and I was able to get half out by digging at it. In the back, there was an impressive array that climbed up a 10-15 foot tree and was in a mass 6 feet wide. I had to wait for a bird nesting there to move out before taking it down. Some of the vines are an inch thick. Does anyone have a suggestion for killing the roots? I could get a spade and dig them out I suppose. I was worried the kudzu was killing the huge tree
I don't want any chemical sprayed.
