Water hyacinth on St. Augustine water

Water hyacinth (Eichhornia crassipes) is the most visible aquatic invasive in Central Florida. Free-floating mats drift with the wind and pile against shorelines, docks, and stormwater outfalls. A single mat can double in size every 8–12 days during summer. We mechanically harvest mats off the water and haul the biomass off-site so it doesn't decompose in place.

How we handle St. Augustine jobs

We deploy surface harvest boats to cut, collect, and transport hyacinth biomass. Shoreline booms catch drifting mats before they reach docks. Recurring maintenance keeps coverage under 5% and prevents the rapid bloom-and-decay cycles that crash dissolved oxygen.

  • ✓Shoreline booms to catch drift

  • ✓Recurring maintenance plans cap regrowth
  • ✓Fully insured FL aquatic operations
