Controlling weeds can be a difficult thing. I know herbicide is something that many people try to avoid and I am in agreement with that. I do admit though I do use “RoundUp” in areas that weeding it very difficult such as along interlock and stone pathways. Glyphosate (RoundUp) herbicide will control most weeds and it does not harm the soil. It a herbicide that works by going through the plants foliage into the roots, killing the plant without leaving residue in the soil. Be careful though because it will kill all plants including those you love.
