I've just 'dug-up' a small lawn to lay a paved path and circle. Now I'm
faced with the problem of what to do with the grass sods.

Most of them will fit face-down on the compost heap but there are a few left
over.

If I burry them grass side down, say a spade depth deep, or even lay them
face-down and cover them with new topsoil in a week or so, would the grass
grow through again?

Cheers Joe.
