From building your own worm bin to how to build a compost tumbler, we've covered plenty of simple, DIY solutions for home composting here on TreeHugger. But what about a worm bin that literally spreads its own contents in your garden? That's the idea behind a worm tower, which—it is claimed—uses free-ranging compost worms to break down organic waste and then move those nutrients out into your garden.
I like to think of myself as a relatively enthusiastic compost geek, but I must confess I have neither heard of, nor experienced, the concept of a worm tower. Nevertheless, the idea of actively encouraging compost worms not just to do their work at composting, but to then spread out into your garden and poop liberally strikes me—in theory at least—as being an elegant, low maintenance way of keeping nutrients cycling in your garden. Looks like lazivore gardening at its finest!
Just one question—anyone got any experience of whether this actually works?
