I tried the free seaweed/kelp harvest from beaches here in S Florida at the dumps in the participating free mulch programs(Xmas trees,pruned chipped yard waste,seaweeds etc.).
So far as it is we can't drive on our beaches(Daytona maybe)some rural areas.
I understand it takes some time to dry out and decompose quick enough for a " next year use".From the dumps all garbge.Fishhooks,fishing line styrofoam ,bottle caps,Cig butts.I would avoid any seaweed from around oilsheen laden boat docks ramps.Large scale earth turning and furrowing I hear is used.
Good Luck.
