I'm posting this question on behalf of a member who is too frightened to join the Forum. Yeah, I know. Don't ask.
She's having fancy flagstone and block tiered semicircular steps built up to the front door, about 4 steps, with spaces for planting between some of the stones, and she's wondering what kind of mix to use as fill inside the structure. For example, I'd probably recommend 9 parts rice-sized gravel and 1 part loam. Looking for suggestions. Zone 6B RI Thanks!
