Part-sun GC that out-competes grass?
I'v e been reading some of the other posts about planting ditches and recommendations for groundcovers for under rose bushes. Which groundcovers can out-compete vigorous grass?
A swale was put in behind my property and the developer blew some sort of grass seed w/fertilizer all over every surface to stabilize the raw soil. It's quite tall stuff with wider blades than fescue. I planted shrub roses at the top of the swale after pulling up grass and putting down 4+ inches of mulch. The grass keeps running rhizomes up and over into the bed and I haven't found a way to totally keep the grass out.
What ground covers may work for me? The area gets bothÂ sunÂ and part-sunÂ exposures.
