A friend asked me for some tough plant suggestions for a sunny hillside on ledge.
Many plant ideas came to mind, but he has already planted junipers and many of them died, notably on the upper steepest parts. I think that is because it is just too steep and needs terracing for the plants to get established.
He would prefer not to tackle a big ($) terracing project and is hoping the right plants can do the job (aesthetics, erosion control, and eventually no-mulch). I was thinking Rhus lo-gro, forsythia 'Gold Tide', cotoneaster, and such.
I'm not sure how he can access all the areas currently to do the planting, but assuming he can (or can hire someone), is there any hope to avoid terracing? What are his options? Are there other tips and techniques to get the job done? Is rip-rap called for? I have a gentle slope in my yard and I know I have to build a small "shelf" of soil in front to keep the root ball level, but I can't envision that technique on such a steep grade.
I took a bunch of pictures:
