Hi - I have a long self-contained bed of compact rhodies and want to find something to help suppress at least some of the weeds between the young plants. I did want to underplant, but they are very low growing and I'm concerned about interrupting their shallow roots. I heard that maybe covering the ground with pine needles would be a good idea. Does anyone have any experience of doing this, or any words of wisdom? I guess all I have to do is figure out where my nearest pine wood is...
The bed is south-facing, sheltered, and has partial shade from the retaining wall.
