Composting watercress scraps with worms
Watercress scraps, including the stems, are an excellent addition to your Bonter worm bin. This delicate, peppery leafy green decomposes extremely quickly and is processed with pleasure by the worms. A simple and effective way to utilize this kitchen waste and contribute to valuable compost.
Can watercress go in your worm bin?
Yes, absolutely! Watercress is highly suitable for vermicomposting in your Bonter. It is a very soft and watery leafy green that is broken down extremely quickly by the worms and microorganisms. Its soft structure and small size make it ideal worm food that contributes to an efficient composting process and the production of nutritious compost.
How much watercress can you add?
You can confidently add watercress scraps to your Bonter regularly, preferably in small quantities at a time. Due to the fast breakdown and the small amount of watercress you usually add, the moisture content is usually easy to manage. Add it as part of a diverse mix of waste. As always, ensure a good balance with ‘brown’ material (such as cardboard or paper) in the overall mix in the bin to prevent an overly wet environment.
What to do instead? Alternatives & waste management
Watercress is ideal for your worm bin, so alternative ways to process scraps are usually not necessary if you have a Bonter! Unused watercress is delicious in salads, soups, or on bread. If scraps remain, the worm bin is the most efficient and sustainable destination. Minimize waste by only buying what you think you need and using everything where possible.

Tips for safe watercress composting
Watercress scraps require no preparation; the leaves and stems can go in as they are. You can optionally mix them lightly with some dry bedding material before adding them. Bury the watercress under the top layer to discourage fruit flies. Due to the fast breakdown and small quantity, watercress rarely causes problems in the bin and contributes to healthy compost. Your Bonter filters odors effectively, for fresh indoor composting.
