This rock face is the view from my conservatory and it's a mix of rock and earth and is/was chock full of weeds. I've been trying to weed it the last two days, it's about 8ft high and I have to do a lot of the weeding from the top where there is a vaguely level flowerbed but it's really precarious trying to weed down the vertical drop...basically I think one of these days I'll fall.
Any ideas what I can do with this? I thought about taking the earth out and leaving bare stone but I don't think that's possible as it seems to be filled in with a hell of a lot of earth, so I think my only option is to leave it covered with soil.
What could I plant to cover all the earth and hopefully not leave space for a load of weeds to come back through? Or any other suggestions welcome
