Composting best practices
Follow these guidelines for successful composting
- Balance the mix: keep 2–3 parts browns : 1 part greens in your home compost bin.
- Chop small: cut scraps and Composty pieces into 1–3 cm strips and mix through.
- Moisture check: aim for wrung-out sponge damp; fix wet with browns, fix dry with greens + water.
- Add oxygen: turn every 1–2 weeks (tumbler: 2–3×/week), pulling edges into the hot centre.
- Setup bin on bare soil, part-shade, lid on; cap fresh scraps with browns to deter flies.
- No contaminants: plastic, microfibre cloths, glossy/laminated paper, oils/fats, meat/fish/dairy, pet waste.
- Don’t go airless: piling without mixing = anaerobic, smelly compost.
- Don’t overload greens: big, wet dumps stall the heap—layer with browns.
- Don’t ignore seasons: winter is slower; cut smaller, turn, insulate.
- Don’t place poorly: avoid sealed concrete and leaving heaps uncovered to heavy rain or harsh sun.
- Don't use compost until it is a crumbly consistency.
