Vermicomposting, or worm composting, turns kitchen scraps and other green waste into a rich, dark soil that smells like earth and feels like magic. Made of almost pure worm castings, it’s a sort of super compost. Not only is it rich in nutrients but it’s also loaded with the microorganisms that create and maintain healthy soil.
Because it’s usually made in modest quantities, vermi compost is often used as top or side dressing for one’s most demanding and deserving plants. Mixed with regular compost it adds a boost to garden soil. Blended with potting soil, it invigorates plants growing in containers, outside or in (properly made vermi compost has a slight, natural smell and is perfectly suitable for indoor use).
