What can and can’t go in my compost bin, and how do I stop issues like smell, pests or slow breakdown?

In Aotearoa, composting is a straightforward way to divert kitchen scraps and yard waste from landfill and turn them into rich soil for your garden. According to the New Plymouth District Council, your compost bin should sit directly on the soil (so worms and microbes can access it) in a sunny, well‑drained spot, and you should alternate layers of “greens” (e.g., fruit and vegetable scraps, coffee grounds, fresh lawn clippings) and “browns” (dry leaves, shredded cardboard, paper) — about 30 % greens to 70 % browns is a good target. 

Ensure your pile stays moist (like a damp sponge) and aerated — if it smells bad or is slimy, add more browns and turn it to let in air. 

Avoid adding cooked food, meat, dairy and pet‑waste in a typical home bin — these attract pests and slow the process. 

After several months (depending on your climate, mix and how often you turn it) you’ll end up with dark, crumbly compost that’s ready for your garden.
