3A balanced diet
Your compost needs a 50/50 balance of food scraps and garden scraps. For every bucket of food scraps you'll need to add one bucket of garden scraps.
Technically anything organic (once living) can be composted, but in a small backyard compost bin it's best to be careful and follow these guidelines.
All food and drink scraps, including chilli, garlic, citrus, grains, dairy and tiny amounts of meat. Food scraps are wet and high in nitrogen encouraging compost to break down. Substitutes include: manure, fresh grass clippings and seaweed.
All grass and plant clippings, leaves, mulch and woodchips. Garden scraps are dry and high in carbon so they’ll stop your compost smelling. Substitutes include: shredded paper and cardboard, coffee husks and grain husks.
Avoid adding more than 100g of meat, tofu, dairy, eggs or oils at one time. Avoid more than 500g of carbohydrates or citrus. Avoid: gum leaves or pine needles, wood, inks or vacuum dust with unwanted chemicals, dog or cat poo.
- Diversity is the key; too much of one thing can cause an imbalance in your compost
- Chop food scraps and garden scraps in to pieces smaller than a golf ball - the smaller the pieces the faster they will break down
Did you know?
Weeds can be composted but you probably don't want their seeds to grow in your garden. Kill the seeds before you compost them by soaking weeds in a tub of water for a month or two. They'll break into a rich sludge that you can use in your compost as a substitute for foodscraps.
