Get The Mix Right
Make sure you are adding a good mix of 'greens' and 'browns' to your heap - roughly a half and half mix by volume. The combination of nitrogen based and carbon based materials is what is required to create good compost.
Green materials include grass cuttings, weeds, vegetable peelings, tea leaves and coffee grounds
Brown materials include shredded paper, old newspapers and magazines, boxes, toilet roll centres
Whether you are adding greens or brown,s chop them up in to smallish pieces, and make sure everything gets well mixed up.
