Frequently Asked Questions

AI
Yes, standard garden earthworms are not suited for bin composting. You should look for Red Wigglers (Eisenia fetida), which are specifically adapted to live and feed in organic waste layers rather than deep soil.
Odors are usually a sign of overfeeding or lack of aeration. If you maintain the correct balance of bedding and food waste, a healthy vermicompost system is virtually odorless and the same as forest floor soil.
Concentrated liquids are excellent for quick absorption and immediate nutrient delivery, while solid castings are more reliable for long-term soil structure and improvement.
