Panicum virgatum as groundcover for erosion control

8 years ago
last modified: 8 years ago

I'm thinking of installing Panicum virgatum Northwind on a steep (45 degree) slope behind my house. It's rocky clay soil with 5-6 hours sun in summer. My intention is to have an attractive groundcover that gives good erosion control. I have a few questions:

1. Will the clumps continue to expand indefinitely? I'm not sure I want it to totally fill in.

2. What will happen if I never divide the clumps? Dividing would be prohibitively difficult/expensive, given the slope and quantity. Are there alternatives to dividing?

3. My neighbor has an oak that will dump some leaves. Will the grass look terrible and or be hurt by getting oak leaves wedged inside?

4. I will presumably still be fighting weeds in the spaces in between. Will something like Weed b gone kill the switchgrass, or does it survive like turf grass?

Any other comments/advice on my plan would be much appreciated. It's a pretty expensive project, so I want to get it right.
