Frequently Asked Questions

Q: How deep do I bury the underground worm compost bin?

A: The worm compost bin is designed to be buried so that only the lid remains at or slightly above the soil surface. For the Size S (11 cm tall) and Size L (16 cm tall), simply dig a hole to the body's depth, leaving the top accessible. This keeps the composting process underground where earthworms thrive while making it easy for you to add kitchen scraps.

Q: What can I put into the inground composter?

A: You can add most organic kitchen scraps such as fruit and vegetable peelings, coffee grounds, tea bags, and crushed eggshells. Avoid meat, dairy, oily foods, or anything that could attract pests. The enclosed design and soil burial help manage moisture and temperature for optimal worm activity.

Q: Do I need to buy worms separately?

A: Yes — the kit does not include worms. You can purchase red wigglers (Eisenia fetida) or other composting worms from a local garden centre or online. Once added to the buried bin with organic material, they will quickly establish and begin producing nutrient-rich worm castings for your garden.

Q: Is this composter suitable for a small balcony garden?

A: Absolutely. The compact round shape — especially the Size S — is ideal for container gardens, planter boxes, and raised beds on balconies. Burying it in a large planter pot works well, keeping the process tidy and discreet.
