There are four main approaches. Pick the one that fits your space, budget, and lifestyle.
- Bin composting - The easiest option for beginners. Buy a ready-made bin or build one from wood pallets. Works well in small to medium yards.
- Tumbler composting - A sealed, rotating drum that speeds up decomposition. Easy to turn and keeps pests out, but holds less volume.
- Vermicomposting (worm bin) - Uses red wiggler worms in a compact bin. Works indoors or on a balcony, perfect for apartments.
- Pile composting - The simplest method if you have a large yard. Just heap your materials in a designated spot. Needs the most space but costs nothing to start.
Where you place your compost matters. A good spot makes maintenance easier and keeps things running smoothly.
- Partial shade - A shady spot prevents the pile from drying out too fast in summer.
- Flat, well-drained ground - Avoid low spots where water pools. Place directly on soil so worms and microbes can enter from below.
- Convenient kitchen access - Keep it close enough to the kitchen that you will actually use it. A long walk means skipped trips.
- Good drainage - Water should flow away from the pile, not sit underneath it.
- At least 3 x 3 feet of space - A pile needs volume to generate enough heat for decomposition.
Composting works when you balance two types of materials:
Greens (nitrogen-rich): Fruit and vegetable scraps, fresh grass clippings, coffee grounds, tea leaves, and fresh plant trimmings.
Browns (carbon-rich): Dry leaves, shredded cardboard, newspaper, straw, wood chips, and sawdust.
Aim for roughly a 3:1 ratio of browns to greens by volume. Too many greens and the pile gets slimy and smelly. Too many browns and decomposition slows to a crawl.
Yes, compost these:
- Fruit and vegetable scraps
- Eggshells (crushed)
- Coffee grounds and paper filters
- Tea bags (remove staples)
- Yard waste: leaves, grass clippings, small branches
- Shredded paper and cardboard
No, keep these out:
- Meat, fish, and bones (attract pests and create odor)
- Dairy products (create odor, attract rodents)
- Oily or greasy food
- Pet waste (contains harmful pathogens)
- Diseased plants (can spread disease to your garden)
- Treated or painted wood
Layer your materials like a lasagna. It does not need to be perfect, but layering helps air flow and speeds things up.
- Start with a 6-inch layer of browns (dry leaves, straw, or shredded cardboard) at the bottom.
- Add 2 to 3 inches of greens (food scraps, grass clippings).
- Continue alternating layers as you add materials over time.
- Add water until the pile is damp like a wrung-out sponge. Moist, not dripping.
- Top with a layer of browns to prevent odors and discourage flies.
A little regular attention keeps your compost healthy and productive.
- Turn every 1 to 2 weeks to add oxygen. Use a pitchfork or compost aerator.
- Keep it moist but not wet. If it feels dry, sprinkle water. If it is soggy, add more browns.
- Add materials regularly to keep the process going.
Troubleshooting:
- Too wet or smells bad? Add more browns and turn the pile to improve air flow.
- Too dry or not breaking down? Add water and more greens. Check that the pile is big enough to retain heat.
- Attracting pests? Make sure you are not adding meat or dairy. Bury food scraps under a layer of browns.
Compost is typically ready in 2 to 6 months, depending on the method, climate, and how often you turn it.
Signs it is ready:
- Looks like dark, crumbly soil
- Has a pleasant, earthy smell
- Original materials are no longer recognizable
- Cool to the touch (no longer generating heat)
How to use it:
- Mix into garden beds as a soil amendment
- Spread as top dressing on lawns
- Blend into potting mix for containers (1 part compost to 2 parts soil)
- Brew into compost tea for liquid fertilizer
Start small with a kitchen counter compost bin. Once you get the hang of it, scale up to a full outdoor system.
