I put Round up grass-weed killer inside of my landscape garden, but it's killing grass outside of the garden?
I have landscaping rocks which circle around the garden that we have with flowers/shrubs here in Milwaukee, WI. I put Round Up on the weeds and grass inside of the garden, but now the problem is that the Round Up is killing some of the lawn next to the landscaping rocks. What should I do now since the grass is turning a bit yellow outside all around the rocks which affected the lawn that is growing next to the rocks externally?
Round up is a great product but you gotta be kind of careful when using. It is basically a topical herbicide and affects only living tissue that it comes in direct contact with. There obviously was a bit of a wind when you sprayed the grass inside your garden, and the product drifted to the outside. I would pull the yellowing grass and re-seed the area where you want grass to grow. Once Round up hits the soil, it becomes inert after a day or two so you can plant in a few days and it should be ok. good luck. To avoid this in the future, use a piece of cardboard to block any product over spray.
