Okay, I know a bit misleading subject line, but ... You were thinking back hoe, dynamite, swearing, etc..
I have little trees growing all over the place. I think they are either cotton wood or some kind of aspen. The have very long tap roots. If I pull them when the are 6" tall, I can get the 10" tap root too and that is the end of them.
BUT, if they get any bigger , I can not get the tap root out and they keep growing back and back and back. I have tried cutting them flush to the ground. I have tried stripping all the bark and leaves off. And they adore vinegar. They keep coming back and back and back.
So I have a bunch of little 1/4" to 1/2" stumps that keep regrowing. How do I kill off these stumps. (I do not want to use roundup do to my wife's chemical sensitivities.) Small firecracker?
