Hi... I have an area in my garden that is covered with white stones. The weeds are growing up thru the stones as the plastic isnt working anymore. I would like to spray a weed killer on them. I would like to use just one of those quart squirt containers filled with it. I need a strong weed killer. Can you recommend two different ones for me? It should be the type that kills many kinds of weeds. thanks, Dorian |
