Composting is one of the easiest ways to cut kitchen waste and feed your garden — but one wrong move turns the bin into a smelly, pest-attracting mess. Four basics keep it breaking down cleanly: balance the materials, keep the wrong things out, turn it for air, and know when it's done.

What's the right ratio of greens to browns?

Balance greens and browns — roughly 1 part green to 3 parts brown. "Greens" are nitrogen-rich (food scraps, grass clippings, coffee grounds); "browns" are carbon-rich (dry leaves, cardboard, shredded paper). Too many greens makes it slimy and smelly; plenty of browns keeps it sweet-smelling and breaking down. When in doubt, add more browns.

What should never go in a compost bin?

Keep meat, dairy, oils, and pet waste out of the bin. These rot badly, smell, and attract rodents and pests — exactly what turns a tidy compost pile into a problem. Stick to fruit and veggie scraps, yard waste, coffee grounds, and eggshells. Leaving the wrong things out is the difference between earthy and awful.

Why turn the compost?

Turn it every week — air speeds up the breakdown. Composting needs oxygen; turning the pile with a fork or tumbler aerates it, which makes the microbes work faster and prevents the anaerobic, stinky decomposition. A weekly turn is the single biggest thing you can do to speed up finished compost and keep odors down.

How do I know when compost is ready?

Know when it's ready: dark, crumbly, and it smells like earth — not like the food scraps you started with. Finished compost looks like rich, dark soil with no recognizable scraps. That's when you mix it into garden beds or use it as mulch to feed your plants for free.

Frequently asked questions

Why does my compost smell bad?

Usually too many greens (or food scraps not buried), too much moisture, or not enough air. Add browns, turn it, and bury fresh scraps in the middle. A balanced, aerated pile smells earthy, not rotten.

How long does compost take?

Anywhere from a couple of months to a year, depending on the balance, how often you turn it, and the weather. Turning weekly and keeping the greens/browns balanced is what speeds it up.

FAQ

Can you compost in winter when it's freezing outside?

Yes, but it slows down significantly in freezing temperatures because the microbes become less active. You can keep adding materials all winter and it will resume breaking down when temperatures rise in spring, or insulate the bin with extra leaves or straw to maintain some warmth.

What's the best type of compost bin for a small backyard?

A tumbler bin works well for small spaces because it's compact, enclosed to keep pests out, and easy to turn without a pitchfork. If you have even less room, a countertop or under-sink vermicompost bin with worms can handle kitchen scraps indoors year-round.

Do I need to add water to my compost pile?

Only if it's too dry — compost should feel like a wrung-out sponge, damp but not dripping. If it's dusty and not breaking down, sprinkle water when you turn it; if it's soggy or smells bad, add more browns to absorb the excess moisture.

Can I compost citrus peels and onions?

Yes, but in moderation — they break down more slowly and can temporarily slow the process or repel some beneficial organisms if you add too many at once. Chopping them smaller and mixing them well with browns helps them decompose faster.
