Mine are covered in cedar chips and now have 2 ft of new growth on them. I
would say use cedar chips, put landscape fabric down first and cover it with
3-4 inches of chips.

Is it bad to use cedar chips for groundcover on rosebeds? Does the wood
chip leach nitrogen when it's on the ground surface? And, is the
cedar-water runoff bad for roses?
