We've had real problems keeping weeds at bay on our brick patio, which was laid directly on the soil. Now I'm tearing up the patio because of a sewage problem and I'm thinking of putting down a dry-laid stone patio with some decorative brick. I'm hoping that I can plant something like creeping time or dwarf mondo in the joints between stones and keep weeds at bay that way.
Is this a good idea? If I do this, do I just lay the stones on the soil, or should I go the whole gravel and sand route? That is, will the plants I want grow in the sand or do I need real soil there? Or will this just get overrun with weeds, too, and I should just mortar the whole thing?
