Composting

To make good compost you will need to have a mixture of green and brown materials. Green materials contain a high percentage of nitrogen and breakdown quickly; brown materials contain a high percentage of carbon and breakdown slowly. Aim for a 50/50 mix of both wet greens and dry browns. For example, for every caddyful of fruit and vegetable peelings you add, match it with a caddyful of scrunched paper and cardboard packaging.
It can take approximately 6-9 months to make your compost. Finished compost is a dark brown, almost black. It has a spongy texture and is rich in nutrients. Spreading finished compost into your flowerbeds greatly improves soil quality by helping it retain moisture and suppressing weeds.



Tip: If your compost heap tends to be wet & smelly, add more browns; if it is dry, add some greens.
