Permanently Get Rid Of Grass In “Existing” Flower Bed

Question

I have existing perennials in my flower beds and have a terrible time getting rid of existing grass. Seems like I never get the roots of the grass and some may have \”attached\” to some roots of my flowers. What a pain! I have 1 area that has only Hybiscus (huge) and many daffodils and the grass has clups growing in between and then at the base of the Hybiscus. Want to save the huge Hybiscus as they are from my Mom and are 20+ years old and gorgeous. Please help….Thank You! Carole

Answer 1

The preferred method for most will be to place cardboard on the weedy areas and wet it. Leave it until everything under it is killed off. Then you can remove and have something else established in its place.

Another option is selective chemical herbicides.
Selective herbicides such as fluazifop-p-butyl, clethodim, and sethoxydim are commonly used to control grasses while sparing broadleaf plants in various settings like lawns and gardens. They selectively target and manage unwanted grassy growth, preserving the desired vegetation.
