A euphemism for “worm poop”.
Worm castings, also known as worm poop, are the nutrient-rich waste produced by earthworms. These castings are like black gold for gardeners as they contain a plethora of beneficial microorganisms and nutrients that enrich the soil. When added to gardens or potted plants, worm castings improve soil structure, boost plant growth, and enhance overall plant health. Plus, they’re completely organic and an excellent natural alternative to chemical fertilizers. So, if you want to give your plants a healthy and eco-friendly boost, worm castings are the way to go!
