Vermicomposting  is the process in which worms turn organic wastes into very high quality compost. Certain species of worms such as Red Wigglers are a species of earthworm adapted to decaying organic material. These worms thrive in rotting vegetation and compost. The worms create Vermicast also called worm castings is the end-product of the breakdown of organic matter by the worms. Vermicompost contains water-soluble nutrients and it is an excellent, nutrient-rich organic fertilizer and soil conditioner.

Benefits of Vermicompost:


  • Improves soil aeration
  • Enriches soil with micro-organisms
  • Microbial activity in worm castings is 10 to 20 times higher than in the soil and organic matter that the worm ingests
  • Attracts deep-burrowing earthworms already present in the soil
  • Improves water holding capacity
  • The castings are rich in humic acids, which condition the soil and help balance pH
  • Improves nutrient recycling

Plant growth

  • Enhances germination, plant growth, and crop yield
  • Improves root growth and structure
  • Enriches soil with micro-organisms
  • Finished vermicompost can be mixed directly into the soil as a soil amendment, as plant medium or used to make compost tea.


  • Provides plants with essential  nutrients and aids in the suppression of plant diseases.
  • Worm castings contain five times more nitrogen, seven times more phosphorus, and 11 times more potassium than ordinary soil, the main minerals needed for plant growth.

At Harrington’s, we manufacture high quality finished Vermicompost. We sell specialized mixtures of Vermicompost with added humate, fulvic acid, kelp, sea-salt, and beneficial bacterial and fungal inoculums which enrich the compost with essential trace elements and microbial foods and promote a healthy and diverse soil foodweb community. We also make our compost tea extract from our vermicompost which is a main component of our lawn and plant health care services.


“All the fertile areas of this planet have at least once passed through the bodies of earthworms.”
