Frost Seeding Question

[Highmark]

I got some ground that is too rocky to till up which I'd love to frost seed. I killed off the resident grasses with roundup this fall but there is plenty of the old residual material there. Is there any particular seed that works best in areas you cannot get down to the soil?

Could you burn or rake some of the old residue away?

Clover,clover,and more clover. It loves rough rocky soils and is easy to start. Ensure your ph is right and it will even be sweet to your taste.
