My ground is covered by black membrane and chipped bark to keep weeds away while we plant our new garden. But I don't really know whta I'm doing so I've got what is probably a very ignorant question:
I've bought some ground cover plants (Phlox). Do I just cut slits in the membrane and plant through it, like I did with my fuchsias, or do I have to peel back the membrane and leave the ground exposed in order for the phlox to establish itself and spread?
