Make organic compost at home by layering carbon-rich browns with nitrogen-rich greens, keeping the pile damp, and turning it for airflow until it darkens into soil-like humus.
One part kitchen scraps, two parts dry leaves, a little water, and a few weeks of patience — that’s the whole recipe.
Choose The Right Spot For Your Compost Pile
Pick a yard area with good drainage, ideally in a dry, partly shady location close to a water source.
You can build a simple bin from pallets or wire mesh, or buy a tumbler or stationary unit. Either way, the pile needs contact with the ground so soil organisms can move in and do the decomposing.
Layer Your Browns And Greens In The Right Ratio
- Browns: dry leaves, straw, shredded newspaper, cardboard, twigs, wood chips
- Greens: fruit and vegetable scraps, grass clippings, coffee grounds, eggshells, fresh plant trimmings
Chop or break up tough scraps like corn cobs and broccoli stalks before adding them — smaller pieces decompose faster. Keep kitchen scraps in a closed container indoors, then mix them into the pile each time you add them.
That layer keeps odors down, discourages pests, and maintains the balance the pile needs.
Keep It Moist, Aerated, And Working
Your compost should feel like a wrung-out sponge — damp but not soggy. If it’s too dry, decomposition stalls; if it’s too wet, it turns smelly and slimy. Water the pile during dry spells and add more browns if it gets waterlogged.
Turn the pile every week or two with a pitchfork or shovel. This introduces oxygen, which the microbes need to break down organic matter efficiently. A pile that’s working properly heats up in the center, then gradually cools as the material finishes decomposing.
Ready compost is dark, crumbly, and earthy-smelling, with no visible food scraps left. If your pile smells like rotten eggs or ammonia, you’re likely short on browns or airflow.
What NOT To Put In Your Backyard Compost
Standard home compost bins handle food scraps and yard trimmings, but several common items belong elsewhere.
You should also avoid metal, glass, plastic, pet or human waste, treated or painted wood, coal ash, and diseased plants.
Common Composting Mistakes To Avoid
Most failed piles trace back to the same few errors. Too many greens and not enough browns creates a wet, smelly mess. Failing to cover food scraps attracts pests. Letting the pile dry out halts decomposition entirely, and skipping turns starves the pile of the oxygen it needs.
If you have more kitchen waste than your pile can handle, vermicomposting — worm composting — is the EPA-blessed alternative.
Once your compost matures, spread it over your vegetable beds or work it into the soil before planting. If you’re ready to buy a commercial product instead, our roundup of the best compost for an organic vegetable garden compares the top bagged options side by side.
FAQs
How long does it take to make compost at home?
The speed depends on the brown-to-green ratio, moisture, aeration, and particle size. Chopping scraps smaller, turning the pile weekly, and maintaining proper moisture shortens the timeline considerably.
Can I compost citrus peels and onion skins?
Yes, citrus peels and onion skins are fine in moderation. Worms and microbes handle them, though very large amounts can make the pile too acidic. Chop them up and mix them well with plenty of browns to keep the balance healthy.
Is compost from a home bin safe for vegetable gardens?
Avoid using compost that still contains meat, dairy, or diseased plant material, since those can harbor pathogens or survive to reinfect crops.
