Our worm farms handle our veggie wastes. The veggie scraps are slightly buried in a coconut coir bedding and the bacteria that break down the scraps are worm food.
The worms are fed to our chickens and our fish and placed under mulch around our trees and gardens. The worm poop is also some of the best fertilizer around. It is natures soon perfect fertilizer and the farm will help concentrate those goodies. We also have a free source of fishing bait for downtime and ice fishing!
Worms require some moisture in their bedding, but they are also very good at drowning themselves if you go with too much moisture.
Temperature also plays a critical role in the growth, reproduction, and survival of the worms. Worms generally slow down in cold temps, but they almost literally boil to death in warmer temps. Let them get too hot and your colony will be wiped out at once.
Red wrigglers are our preferred breed, but we do pick up a lot of earthworms from the yard in summer. The earthworms tend to dig deep holes that aerate soils well and transfer nutrients between upper and lower strata of the soil, while the wrigglers are surface feeders and tend to stay just below fallen leaves on the soils surface in the wild.
