Vermicomposting straw
Straw is excellent and highly suitable ‘brown’ material for your Bonter vermicomposter. It provides valuable carbon, contributes to an airy structure, and helps regulate moisture. An ideal, safe base for your worm bin that contributes to healthy and efficient composting.
Can straw go in your worm bin?
Yes, absolutely! Straw is very suitable for vermicomposting. It is a rich source of carbon (‘brown’ material), essential for balancing nitrogen-rich food waste (‘green’ material). The hollow, stiff structure of straw contributes significantly to aeration in the bin, which is crucial for preventing anaerobic conditions and the well-being of your worms. It also absorbs excess moisture and provides an airy structure. Straw breaks down more slowly than paper but faster than wood. Preferably use straw from organic cultivation to avoid pesticides.
How much straw can you add?
Straw can be added regularly and in generous quantities to your Bonter, preferably cut or chopped. It is a perfect basic bedding material. Make sure you always add enough ‘brown’ material (such as straw, cardboard, paper, dried grass, leaves) to balance the amount of ‘green’ food waste. Straw is excellent for creating a new layer of bedding, for adding if the bin gets too wet, lacks structure, or becomes compacted. Mix it well throughout the bin for optimal results.
What to do instead? Alternatives & waste management
Straw is so suitable and useful as ‘brown’ material and bedding in the Bonter that you should ideally save it for that purpose! It contributes significantly to a healthy and well-performing compost bin. If for some reason you have an exceptionally large amount of straw, it can also be used on a traditional compost heap as structural material or as a ground cover in the garden. Straw is also widely used as stable litter for small animals; this can be composted with the droppings (provided they are from herbivores, and with due attention).

Tips for composting straw
Cut or chop straw into smaller pieces (about 5-10 cm) before adding it. This increases the surface area and significantly speeds up decomposition. Moisten the straw by mixing it with wet food waste or burying it under the moist bedding in the bin; material that is too dry composts slowly. Mix the cut straw well with the waste and existing bedding to add structure and aeration throughout. Preferably use straw from unsprayed sources. The Bonter’s air filter helps with odours, but a good mix of brown and green, and sufficient aeration (which straw excellently helps with), prevents problems at the source.
