We have a CYV and replaced most of our grass with river rock to ensure we'd have low maintenance during the months we are absent.
But it is Florida, and we've found that weeds grow on and around rock! So now, in the months we are absent, instead of paying someone to cut the lawn, we pay someone to weed and cut the bit of lawn we keep for our dogs.
Also, I am amazed at how vigorously shrubs grow in Florida. Some grew three feet in the six months we were gone.
I think is is almost impossible to have no maintenance unless you concrete everything over.
