A French drain and/or a swale are mechanical ways to direct water away, if you want to add some landscaping to dry it out, try some
bald cypress trees. That's a native Florida solution to the problem, and it is sad that so many of them were cut down. I'd offer to send you some seeds, but you are in bald cypress central, and with a little searching, you can probably find ones of all sizes from recently sprouted twigs to ones in 50 gallon tubs.
