How to Start Composting

Turn your food scraps and yard waste into rich, dark soil that your garden will love.

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.
