Meg - The fish poop was me, but I put the idea on the backburner. Right now I mostly feed it straight to my bananas, and they're showing their thanks with 15 bunches (and 5 more soon): Dwarf Brazilian, Dwarf Cavendish (3), Dwarf Namwah, Dwarf Orinoco (4), Dwarf Red, Grand Nain, Pisang Ceylon, Pisang Mas, and SH-3640 (2). It's awesome that plants can convert fish poo into such delicious treats!
Kerry & George - Thanks :)
