While I was researching aquaponics I stumbled across this concept of building a worm tower. Basically you bury some pipe and fill it with compost worms and kitchen scraps, etc. The worms will crawl through your garden and leave their castings behind. It’s a pretty cool concept, one which I will be experimenting with this spring.
Here is a great source for composting worms. Red Worm Composting. I’ve been planning to make a few worm bins this year also.
