FAQ
What’s the best surface to place my 100 Litre Compost Bin on?+
Ideally, position your bin on a level concrete patio, gravel path, or compacted earth. Avoid placing it directly on grass as this can lead to waterlogging and potential pest issues.
How often should I turn the compost in my 100 Litre Bin?+
Turning your compost regularly – ideally once a week – helps aerate it and speeds up decomposition. A pitchfork or turning tool is useful for this, ensuring good airflow within the bin.
What materials can I compost in a 100 Litre Compost Bin?+
You can compost most garden waste like leaves, grass cuttings, and small twigs alongside kitchen scraps such as fruit and vegetable peelings. Avoid composting meat, dairy products, or oily foods which can attract pests and create unpleasant smells.
How do I know when my compost is ready?+
Your compost is ready when it's dark brown, crumbly, and has an earthy smell. You shouldn’t be able to recognise the original materials within the mixture.

While not strictly necessary, lining the bin with cardboard or hessian sacking can help absorb excess moisture and improve airflow – this is particularly useful if you live in a wetter climate.
