(user asked about growing lawn grass)
What about a ground cover plant instead of lawn grass? The advantage of purslane is that you can eat it. It's good on salads.
If sandy soil and if it receives some sunshine, what about native prairie plants, like Oak Openings natives?
If too shady, try hostas, especially if you know someone who can share some with you.
Or maybe a mix of plants, including lawn grass.
Our Oak Openings natives, hostas, and some kind of ground cover plant do well on our sandy soil that's mostly shaded. The less lawn grass, the better for me.
You may need some small shrubs to help prevent erosion on a slope. How steep is the slope? Do you need to terrace it?
I'm sure holland can provide info.
