DIY Vermicomposter: How to Turn Kitchen Scraps into Garden’s Gold with Worm Power

How to Make a Homemade Vermicomposter

Vermicomposting is a fantastic way to recycle kitchen waste while producing nutrient-rich compost for your garden. In this guide, we’ll walk you through a simple and effective method to create your own vermicomposter using a three-tote system.

Materials Needed:

  • Three durable plastic totes (Roughneck brand is recommended for their durability)
  • One lid for the totes
  • A cooler drain or similar item for drainage
  • Drill with a quarter-inch bit
  • Bricks or blocks for elevation

Step-by-Step Guide:

1. Preparation of Totes:

Start by drilling quarter-inch holes in the bottom of two of the totes. These holes are essential for allowing worms to migrate between layers and facilitating drainage.

Next, drill holes around the upper edges of these totes to ensure adequate aeration.

2. Setting Up the Drainage System:

The bottom tote will function as your drainage collector. Install the cooler drain on the recessed side of this tote for effective drainage.

The drilled holes will allow excess liquid—known as “worm tea”—to drain out, providing you with a nutrient-rich liquid fertilizer for your plants.

3. Assembling the Vermicomposter:

Stack the two drilled totes above the drainage tote. These will serve as the living quarters for your worms and the composting area.

Initially, the worms and compost material will go into the top tote.

4. Transferring the Worms:

Carefully transfer your worms into the top tote, along with their bedding and any food scraps. As the top tote fills with worm castings, shift it to the middle position, making the newly top tote the active composting layer.

5. Maintenance and Harvesting:

Continue adding kitchen scraps and bedding to the new top layer. The worms will migrate upwards toward the fresh food, leaving behind rich compost in the lower tote.

When a tote is full of castings and mostly devoid of worms, it can be emptied into your garden.

Regularly check the bottom tote for worm tea and use this nutrient-rich liquid as a fertilizer for your plants.

6. Elevating the System:

Raise the entire setup on bricks or blocks. This elevation improves drainage and accessibility, making the system easier to manage.

Conclusion

Creating a homemade vermicomposter is a rewarding project that contributes to a sustainable environment. This three-tote system is efficient, cost-effective, and provides your garden with rich, organic compost. As you become familiar with the process, feel free to experiment and adapt the system to better suit your needs. Happy composting, and enjoy the benefits of your own organic garden!
