Appreciate that very much!
Those flagstones very thick and I do try to back fill but it either washes or ...well I don't know.
The weeds "appear" to be at surface but in some spots several inches deep to reach the hoeing surface. So I hand weed...but I really hate it.. Snakes have emerged from under a flagstone or two. I don't see how...but they do .. hate to use my hands --even gloved. Amazing, can grow beautiful thick weeds between those stones but not a strong stand of ground cover.
