Southwest Florida gets most of its yearly rain between June and September, often in short, heavy afternoon storms. Flat lots, sandy fill and a high water table mean that water has nowhere to go fast. The yard stays soggy, beds wash out, and water sits against the house.
Look for the warning signs now
Water that stands more than a day after a storm, mulch or rock washed onto walks, bare or yellowing patches in low spots, and downspouts that dump right at the foundation are all signs the yard needs help before the next storm season.
Fixes that work here
Most problems come down to grading: the ground should slope away from the house. Regrading fixes many yards on its own. Where it doesn't, a French drain (perforated pipe in a gravel trench wrapped in fabric) collects water underground and carries it to a better spot. Buried downspout extensions move roof water away from the slab.
Plant choice helps too. In spots that stay wet, plants that tolerate wet feet, like native Fakahatchee grass, hold up far better than turf.
Timing
The dry season, roughly November through May, is the easiest time to regrade and install drains: the ground is firm and you're ready before the rain returns.
