Abstract:
Red wiggler earthworms can be used in worm bins or garden beds to help break down food waste or yard debris into a type of compost called worm castings. These castings provide excellent nutrition to plants and can be applied as a soil amendment or brewed into a tea to be applied as a soil drench or a foliar spray. In a worm bin, worms require regular addition of bedding (damp shredded paper) and food (decaying plant material). They should be kept at temperatures between 50 and 75 degrees Fahrenheit. In a garden bed or compost heap, worms require no care and will work to break down plant debris and improve soil health.
