hens and chicks in crevasses
I have a new stone patio, about 10' across, semicircular against the doorway, with step down to 3 X 5 granite slab, then some grass, and another slab, etc, for a curved stepping stone look up the gentle slope to my back door.
The patio has one huge granite slab as the door step, with smaller stones set in the semicircle below it.
Could hens and chickens grow in the overhang of the doorstep? There is a little soil packed in there where I tried to get thyme going, but it fried when we had really dry weather right after I planted it.
What about mixing it with something else, around the slabs that make up the stepping stones?
