Seems to me that you will need a proportial amount of lime applied to the

Why not use boiling water? It's pretty much organic and pH neutral unless
you're on a problem well.

Has anyone tried Vinegar as an herbicide for weed control as the following
sources suggest? If you have, where can I get 20% vinegar either in Durham
or the triangle area?
