Or encourage the local birds more. The local crows have done a great job of
cleaning the moss from the "patio" (if you knew my garden, you'ld be
laughing at this point) for use in their nests.

Also, moss likes the damp so if you have heavy, slow draining soil (I have
London clay - anyone for pottery?), then improving the drainage can help.
Lawns, especially, are prone to getting compacted and aeration and dressing
in the autumn really helps.
