Mulch Installation in Sanibel, FL
The city's Vegetation Committee points out that sea grape leaves make a natural mulch, and many Sanibel yards rely partly on leaf litter from native shrubs. Where beds need added mulch, UF/IFAS guidance is the standard: 2 to 3 inches around established plants, no deeper, and kept clear of trunks and stems. Old mulch should be raked out first so the layer does not keep thickening. Water is the bigger consideration on Sanibel. The middle of the island is a large interior wetland that stores stormwater and drains mainly through the Sanibel River, and during Hurricane Helene city staff reported islandwide flooding. Light mulch floats in that kind of water and ends up in swales and retention areas. In subdivisions like the Sanibel Bayous or Gumbo Limbo, which collect runoff in defined retention areas, heavier mulch and a firm bed edge keep it in the beds. Hodges removes the old layer, then spreads new mulch to depth.

Questions
Can I leave fallen leaves in my beds instead of buying mulch?
Often, yes. The city's Vegetation Committee notes that sea grape leaves make a natural mulch. Leaves from native shrubs break down in place and feed the soil. Fresh mulch is still useful where beds are bare or newly planted.
How thick should mulch be around my plants?
UF/IFAS recommends 2 to 3 inches around established trees, shrubs and bedding plants and warns against going over 3 inches, which can keep water from reaching roots. Keep mulch a few inches off palm trunks and shrub stems.
Why does my mulch wash out after big storms?
Much of Sanibel drains slowly, and when water stands in yards, light mulch floats. Heavier mulches, a bed edge, and keeping mulch out of the lowest part of the yard reduce how much ends up in the swale or retention area.
