Lava rock in dirt - wanting to plant grass
The former owners of my house/foreclosure I bought put lava rock in the strip by the road. I put in a path and am wanting grass, the lava rock half washed away according to a neighbor but there's some left. There's about an inch of room I could spread out dirt from the back yard on top of. Would that help? Or what would I do to prep the strip so that I could plant seed. I don't think I can afford sod but if that's the answer I could if need be. In the front yard I've been successful at seeding and getting the grass to mostly come back, but of course there was no lava rock. I'm new to landscaping.
