|I have rock landscape and the weeds just don't stop coming up all over the yard. What can I use? It is old landscape and I rent this house, not the owner. I have tried round-up and ground clear & it keeps coming up. Weeds come up all over, not just one or two.
|I think weed seeds are sprouting after you kill the existing weeds. Go after the weeds again with Round Up or Brush B Gon then apply a pre emergent product such as Preen. It will keep weed seeds from sprouting all summer long.
