How To Remove Grass From Flower Bed

Use a grass specific herbicide on these weeds. Try herbicides with the ingredients clethodim, sethoxydim, or fluazifop-p which will kill grass but not damage flowers and shrubs. If you have vegetables nearby—and to be extra careful with flowers and bushes—use cardboard as a barrier when you spray.

How do I stop grass from growing in my flowers?

By nature, most all plants are attracted to sunlight and they will naturally grow in that direction. Keeping your flower beds topped with between 2-3 inches of mulch at all times will create a shady barrier in your bed and discourage grass from invading. PRO: Mulch is readily available and reasonably inexpensive.
