Composting is breaking down organic waste, such as food scraps, leaves, and grass clippings, into which you can enrich your garden beds with a soil amendment that is abundant in nutrients. By composting, you can not only reduce your waste but also enhance the health of your soil.
Key takeaways
- Balance roughly two to three parts brown materials to one part green materials
- Keep the pile as damp as a wrung-out sponge and turn it every week or two
- Leave out meat, dairy, oily foods, pet waste, and diseased plants
- Finished compost is dark, crumbly, and smells earthy, ready to mix into beds
Benefits of Composting
- Reduces Waste: By composting, you can divert organic waste from the landfill, which can help reduce greenhouse gas emissions and conserve landfill space.
- Enriches Soil: Compost is rich in nutrients that plants need to thrive, such as nitrogen, phosphorus, and potassium. It can help improve soil structure and retain moisture.
- Saves Money: With composting, you can lessen your reliance on expensive fertilizers and other soil amendments, leading to cost savings in the long term.
- Improves Plant Health: Compost can help improve plant growth and health by providing a slow-release source of nutrients that plants can absorb over time.
How to Compost
- Choose a Composting Method: There are several ways to compost, including traditional composting, vermicomposting, and composting with a bin.
- Collect Compostable Materials: Add organic waste such as fruit and vegetable scraps, coffee grounds, and yard waste to your compost pile.
- Build Your Compost Pile: Layer your compostable materials with carbon-rich materials such as dried leaves or shredded newspaper to create the right balance of nitrogen and carbon.
- Maintain Your Compost Pile: Regularly turn your compost pile to provide oxygen and promote decomposition. Maintaining the right moisture level in your compost pile is important – not too dry or wet.
Troubleshooting Common Composting Problems
- Compost is Too Wet: Add dry materials such as shredded paper or leaves to absorb excess moisture.
- Compost is Too Dry: Add water to the pile to moisten it.
- Compost is Not Decomposing: Add nitrogen-rich materials such as grass clippings or blood meal to help jumpstart decomposition.
What Can and Cannot Go in Your Compost
Knowing what belongs in the pile prevents most odor and pest problems. Greens are moist, nitrogen-rich materials like fruit and vegetable scraps, coffee grounds, tea leaves, fresh grass clippings, and plant trimmings. Browns are dry, carbon-rich materials like fallen leaves, straw, shredded cardboard, plain newspaper, and small twigs. A mix of both keeps decomposition moving steadily.
Some items are best left out of a home pile. Meat, fish, bones, dairy, and greasy foods attract pests and can create strong smells. Pet waste from dogs and cats can carry pathogens, and diseased plants or weeds with seeds may survive a cooler pile and spread back into your garden. Glossy paper and anything treated with chemicals should also stay out.
A helpful habit is to keep a small covered container in the kitchen for scraps and empty it into the outdoor bin every few days. Chop or break larger items into smaller pieces so they break down faster. When you add a layer of kitchen scraps, cover it with a layer of browns to discourage flies and keep odors under control.

How to Tell When Composting Is Finished and How to Use It
Finished compost looks dark brown, feels crumbly, and smells like fresh earth rather than rotting food. You should no longer recognize most of the original materials, though a few woody bits are normal. Depending on the method, the materials, and how often you turn it, this can take anywhere from a couple of months to a year or more.
Screen out any large chunks and toss them back into the active pile. Spread an inch or two of compost over vegetable beds before planting, mix it into planting holes, or use it as a top dressing around shrubs and perennials. You can also blend a small amount into potting mix for containers. Compost is a soil builder rather than a strong fertilizer, so heavy feeders may still need extra nutrients.
If you are not sure whether it is ready, try a simple test: put some in a sealed plastic bag with a little moisture and leave it for a few days. If it smells sour or ammonia-like when opened, it needs more time. Using unfinished material in beds can temporarily tie up nitrogen and may harm young seedlings, so patience pays off.
Managing Your Compost Pile Through the Seasons
A compost pile slows down noticeably in cold weather, and that is completely normal. In winter, you can keep adding scraps to the bin, and a thick layer of leaves or straw on top helps hold in some warmth. Decomposition will pick back up once temperatures rise in spring. Some families keep a lidded bucket near the back door so they do not have to trek out every day.
Fall is one of the best times to stock up on browns. Bag extra fallen leaves and store them near the bin so you have carbon on hand all year, especially in summer when kitchen scraps and grass clippings pile up fast. In hot, dry months, check moisture more often and water the pile if it feels dusty. Shading the bin can help keep it from drying out too quickly.
Many households find it helpful to run two bins or piles side by side. One receives fresh scraps while the other is left alone to finish. When the second pile is ready, empty it into your beds and start again. This rotation gives you a steady supply of finished compost and makes it easier to judge when each batch is ready.
- Shred leaves with a mower to speed breakdown
- Cover the pile during very heavy rain
- Turn more often in warm weather for faster results
Frequently Asked Questions
How long does composting take?
It typically takes anywhere from about two months to a year, depending on the method and how actively you manage the pile. A well-balanced, regularly turned pile with small pieces breaks down fastest. A cold pile that is rarely turned still works but takes much longer. Warm weather speeds things up, while winter slows decomposition considerably.
Why does my compost smell bad?
A bad smell usually means the pile is too wet, has too many greens, or is not getting enough air. Add dry browns such as shredded leaves or cardboard, then turn the pile to let oxygen in. Also make sure no meat, dairy, or oily food scraps have found their way in, since those often cause strong odors and attract pests.
Can I compost in a small yard or apartment?
Yes. A compact tumbler or small lidded bin fits in most small yards, and many people in apartments use worm bins, known as vermicomposting, kept under a sink or on a balcony. Some communities also offer drop-off sites or curbside collection for food scraps. Check local rules and building policies before setting up a bin outdoors.
Do I need to turn my compost pile?
Turning is not strictly required, but it speeds things up. Mixing the pile every week or two adds oxygen, spreads moisture, and moves outer material into the warmer center. If you prefer less work, a cold pile that you simply add to will still break down, just more slowly. Compost tumblers make turning easier for many homeowners.
Conclusion
Composting is a sustainable gardening practice that offers a range of benefits for your garden and the environment. By reducing waste, enriching the soil, saving money, and improving plant health, This is a valuable tool for any gardener. With the right techniques and a little patience, anyone can compost and enjoy the benefits of this eco-friendly gardening practice.
