Garden & Outdoors guide

Start a simple compost bin

Build a balanced mix of moist green material and drier brown material, then adjust air and moisture when decomposition stalls.

Step by step

  1. Choose an accessible site

    Use a stable spot with drainage and room to add, mix and remove material. Follow local rules for shared spaces.

  2. Add varied material

    Alternate food-free garden greens and suitable kitchen scraps with dry leaves, shredded plain cardboard and small woody material.

  3. Control moisture and air

    Aim for a damp wrung-sponge feel. Add dry browns when wet and compacted; add greens or a little water when very dry. Turn or mix when practical.

  4. Keep problem material out

    Exclude meat, dairy, oils, pet waste, diseased plants and persistent weeds unless the system is designed to handle them.

Ready-to-use checklist

  • Stable drained location chosen
  • Greens and browns available
  • Large pieces reduced
  • Moisture checked
  • Problem materials excluded
  • Access for turning and harvesting clear

Common problems

The bin smells rotten

It is likely too wet or airless. Mix in dry browns and create air spaces.

Nothing seems to happen

Add moisture if dry, mix in fresh greens and reduce oversized material; cold conditions slow the process.
