I do this in Florida. My soil is just sand, so it is easy to get rid of the
lawn - I just let the native plants take over! Now I have a varigated lawn
and I don't irrigate. I just handwater my flowers (native ones). Took out
lots of ixora bushes, planted palms, sea grapes, live oak, etc. My yard is
looking very nice and it's care is easy! Also, my tortoise has lots of good
things to eat now.
