How to Harvest


These worm experts at Waimalu Elementary School know that regular harvesting is important to keep their worms happy and their colonies growing. Harvesting is fun and easy to do.
To maintain the health and efficiency of your worm bin, periodic harvesting and re-bedding is required. When you harvest, you separate out the valuable excreta of the worms – vermicast – which has built up as your garbage has been ingested and processed. Not only should your bin yield a big pile of dark, odorless, nutrient-rich "Gardeners' Gold," but your worm colony may have expanded as well.

For our Mini-Bins and other small box-type containers, we recommend harvesting every 3 to 5 months. This is approximately the time it takes for the original 3-1/2 or 4 inches of paper and cardboard bedding to break down and be consumed by the worms.

Bedding is critically important to maintain structure – air pockets, habitats for other organisms, and safe harbor for baby worms. When bedding disappears, the health of the ecosystem starts to decline. Following your harvest, you will re-bed your worms in fresh bedding material.
