Earthworms Eat Invasive Plants

Now here's a win-win situation. Feed water hyacinths to earthoworms. They don't call this plant "the blue devil" for nothing: it'll clog a river or a lake in no time flat. Turns out that worms love the stuff and 180 tons of yanked-out-and-piled-up water hyacinth will become 60 tons of rich worm castings. Go, worms! Then can you start on my dandelions?
