Suggestions for Groundcover on Steep Hill
My brother has a beautiful home, but his back yard consists of steep hills. (See photo.) He's put down sod on part of his yard, but he's having a difficult time keeping it looking good. He's thinking about some kind of ground cover over a chunk of it to alleviate the eye sore that it is now. The soil is pretty much hard and rocky. Any suggestions on ground cover or anything else that would grow on a steep hill like this? I like the idea of ground cover roses, but those would require a good mulch to look good and I'm assuming it'd be hard to keep mulch in place on such a steep incline.
