You can start composting in your yard or kitchen with materials you already have

Home composting turns food scraps and yard waste into dark, crumbly soil you can use in gardens and potted plants. You do not need special equipment, a large yard, or any experience. The basic method is straightforward: layer brown materials (dry leaves, shredded paper, cardboard) with green materials (food scraps, grass clippings, plant trimmings), keep the pile moist like a wrung-out sponge, and turn it every few weeks. In three to six months, the bottom will be finished compost ready to use.

The speed depends on how often you turn the pile, the size of your materials, and the temperature where you live. A small, turned pile finishes faster than a large, undisturbed one. You can also use a sealed bin, which takes up less space and keeps out pests, though it works more slowly. Both methods work—choose based on your yard size and how much time you want to spend.

Key Takeaways

  • Layer brown materials (leaves, paper, cardboard) with green materials (food scraps, grass) in a 3-to-1 ratio by volume, keeping the pile as moist as a wrung-out sponge.
  • Turn the pile with a shovel or pitchfork every one to two weeks to speed decomposition; an unturned pile takes twice as long but requires no work.
  • Finished compost is dark brown, crumbly, and smells earthy; it takes three to six months in a turned pile or six to twelve months in an undisturbed one.
  • Do not add meat, dairy, oils, or diseased plants; these attract pests or spread plant illness.
  • A sealed bin or tumbler works in small spaces and keeps out raccoons and rats, though it costs $50 to $300 upfront.

Gather your brown and green materials

Brown materials are dry and carbon-rich: fallen leaves, shredded newspaper or cardboard, straw, wood chips, and sawdust. Green materials are wet and nitrogen-rich: grass clippings, vegetable and fruit scraps, coffee grounds, plant trimmings, and fresh manure from herbivores (horse, cow, chicken). You need roughly three times as much brown by volume as green—the brown keeps the pile airy so it does not turn into a wet, smelly mat.

Start collecting brown materials in fall when leaves drop. Shred cardboard boxes and newspaper into strips about 2 inches wide so they break down faster. Save vegetable scraps in a container in your kitchen—onion skins, carrot tops, apple cores, and lettuce leaves all work. Avoid meat, fish, dairy, oils, and diseased plant material; these attract pests or spread illness to your garden.

Choose a location and container

Pick a spot that gets partial sun and is close enough to your kitchen that you will actually use it. Full sun speeds decomposition, but shade works too—it just takes longer. The pile should sit on bare soil or grass, not concrete, so organisms from the ground can move in and help break things down.

You have three main options. A straightforward pile costs nothing: stack materials in a corner of your yard, no bin needed. A wooden or wire bin (3 feet by 3 feet is a good size) keeps the pile neat and contained; you can build one from untreated wood and wire fencing for $20 to $40. A sealed plastic bin or tumbler ($50 to $300) takes up less space, keeps out pests, and lets you turn the contents by rotating or cranking instead of using a shovel. Pick based on your space and how much effort you want to spend.

Layer and moisten your materials

Start with a 4-inch layer of brown material on the bottom—this creates air pockets. Add a 1- to 2-inch layer of green material on top. Repeat until your pile is 3 to 4 feet tall. Water each layer as you go so it is moist like a wrung-out sponge, not dripping wet and not dry.

The pile will heat up as microbes begin breaking down the materials. You may see steam rising on cool mornings—this is normal and means the pile is working. If the pile smells like ammonia or rotten eggs, it is too wet or has too much green material; add brown material and turn it. If it is not heating up and nothing seems to be breaking down, it is probably too dry; water it.

Turn the pile every one to two weeks

Turning speeds decomposition by mixing in oxygen and moving cooler material from the edges into the hot center. Use a shovel or pitchfork to move material from one side of the bin to the other, or from the pile to a new spot next to it. Aim for every one to two weeks if you want finished compost in three months. If you do not want to turn it, leave it alone—it will finish in six to twelve months on its own, just more slowly.

After each turn, water the pile again if it has dried out. The pile should stay moist but not soggy. In a sealed tumbler, you rotate the drum by hand or crank every few days instead of using a shovel; this is less work but requires more frequent attention.

Know when your compost is ready

Finished compost is dark brown or black, crumbly, and smells earthy—like forest soil. You should not be able to see the original materials; they have all broken down. If you see whole leaves, food scraps, or cardboard pieces, the pile needs more time. Sift the compost through a 1/2-inch screen (a piece of hardware cloth over a wooden frame) to remove chunks; put the chunks back in the pile to finish breaking down.

In a turned pile, the bottom layer finishes first. You can harvest finished compost from the bottom while the top is still decomposing. In an undisturbed pile or bin, wait until the whole thing looks dark and crumbly before harvesting. Use your finished compost in garden beds, vegetable gardens, potted plants, or as a top dressing on your lawn.

Troubleshoot common problems

Pile smells bad (ammonia or rotten eggs): It is too wet or has too much green material. Add brown material, turn it, and let it dry out a few days.

Pile is not heating up or breaking down: It is probably too dry, too small, or has too much brown material. Water it, add more green material, or combine your pile with a neighbor's to reach at least 3 feet by 3 feet.

Pests (rats, raccoons, flies): Do not add meat, dairy, or oils—these attract pests. If you have already added them, bury food scraps deep in the center of the pile. Use a sealed bin if pests are a persistent problem in your area.

Pile is too wet after rain: Turn it to add air, or cover the top with a tarp or wooden lid to shed water while still letting air in.

Frequently Asked Questions

Can I compost in an apartment or small space?

Yes. Use a sealed plastic bin (12 to 18 inches tall) on a balcony or in a closet, or try vermicomposting (composting with worms in a shallow bin under the sink). Both work slowly but produce usable compost in four to six months without smell or pests if managed correctly.

What if I do not have a yard?

Community gardens often have shared compost piles where you can drop off scraps and take finished compost. Check your city's parks department or search online for "community garden near me." Some cities also run municipal composting programs that pick up food scraps from your curb.

How long does it really take?

A turned pile in warm weather finishes in three to four months. An unturned pile takes six to twelve months. In cold climates, add two to three months. A sealed bin takes four to six months. Speed depends on pile size, how often you turn it, temperature, and how finely you chop your materials.

Can I add weeds or diseased plants?

Avoid diseased plants—the compost may not get hot enough to kill the disease, and you will spread it to your garden. Annual weeds without seeds are fine. Perennial weeds (like dandelions with roots) can regrow in the compost, so bury them deep in the center where it is hottest.

Do I need to buy a starter or activator?

No. Compost starters and accelerators are not necessary. Microbes are already on your materials and in the soil. A properly layered, moist pile will decompose on its own. Save your money.
