How to mend an eroding hill?

3 years ago

I live at the top of a small wooded bluff that heads down into a creek valley. It’s directly behind the house and over time has seen some epsilon since the house was built (2004) long before we moved in. There’s not a lot growing that’s holding this slope together, just some escaped mondo grass tufts and a few mounds of sedges. I’d like to plant a groundcover through here like Geranium macrorrhizum but the slope is pretty eroded, exposing dead or dying roots from a white oak. Should I backfill here first with top soil? How deep? Do I need a wall at the base, or a couple of paved blocks to hold it all? My goal here really is to stop the hill from eroding, not engineer myself a ton of new garden beds or terraces.

Or do I just plant groundcover plants as is and hope for the best?
