How long does it take to make compost?

Hot composting (turning regularly, proper ratios) produces usable compost in 2-3 months. Cold or passive composting (just pile it and wait) takes 6-12 months. Tumbler composters can produce compost in 4-8 weeks with regular turning.

Does composting attract rats?

Properly managed compost does not attract rats. The key is never adding meat, dairy, or cooked food. Keep the pile moist and turn it regularly. If you are concerned, use an enclosed tumbler composter or a bin with a secure lid and wire mesh bottom.

Can I compost in a small yard or apartment?

Yes. Worm composting (vermicomposting) works in a small bin under the kitchen sink or on a balcony. Bokashi composting uses a sealed bucket. Both are odor-free when managed properly and produce nutrient-rich compost from kitchen scraps.

How to Start Composting: A Beginner's Guide to Garden Gold

Why Compost Is Garden Gold

Compost is decomposed organic matter, and it is the single best thing you can add to any soil. It improves clay soil by loosening its structure and improving drainage. It improves sandy soil by increasing its water and nutrient retention. It adds beneficial microorganisms that suppress plant diseases. It provides slow-release nutrients that feed plants for months. And it reduces your household waste by 30-40% — the average family throws away 200+ pounds of compostable material per year. Making compost is essentially free, endlessly renewable, and produces a product that would cost $30-50 per cubic yard to buy.

What You Can Compost

Compost needs two types of materials: greens (nitrogen-rich) and browns (carbon-rich). Greens include fruit and vegetable scraps, coffee grounds and filters, tea bags, fresh grass clippings, and garden trimmings. Browns include dried leaves, cardboard and newspaper (shredded), wood chips and sawdust, straw, and dried plant stalks. The ideal ratio is roughly 3 parts brown to 1 part green by volume. Too many greens make the pile slimy and smelly. Too many browns and decomposition stalls. If your pile smells bad, add more browns. If it is not decomposing, add more greens.

What NOT to Compost

Never compost meat, fish, or dairy products — they attract rodents and create horrible odors. Avoid diseased plants (the disease may survive composting and infect your garden). Do not add pet waste from dogs or cats (contains harmful pathogens). Avoid treated or painted wood. Do not add weeds that have gone to seed unless your pile reaches 140°F+ (hot composting kills seeds, but most home piles do not get hot enough). Citrus peels and onions are fine in moderation despite common myths, but they decompose slowly, so chop them small.

Choosing a Compost Method

A simple pile on the ground is the easiest start — just designate a 3x3 foot area in a back corner and start stacking materials. A three-bin system lets you have one pile cooking, one curing, and one actively receiving new material. Tumbler composters (rotating drums on a frame) are the cleanest, most pest-resistant option and produce compost faster because they are easy to turn. Worm composting (vermicomposting) works indoors or in small spaces — red wiggler worms process kitchen scraps in a bin under your sink. Bokashi composting uses fermentation and can handle meat and dairy that traditional composting cannot.

The Composting Process

Add materials in alternating green and brown layers. Chop or shred large items to speed decomposition. Keep the pile moist like a wrung-out sponge — not soggy, not dry. Turn the pile every 1-2 weeks with a pitchfork to add oxygen, which is essential for aerobic decomposition. A well-managed pile reaches 130-160°F in the center, which kills weed seeds and pathogens. Compost is ready when it is dark brown, crumbly, and smells like rich earth — typically 2-3 months for hot composting or 6-12 months for passive composting. You cannot over-compost — if you are not sure if it is ready, give it another month.

Using Compost in Your Garden

Spread 2-3 inches of finished compost on garden beds and work it into the top 6 inches of soil before planting. Use it as mulch around established plants (2-inch layer). Mix it into potting soil at a 1:3 ratio for container gardens. Add it to planting holes when transplanting trees and shrubs. Top-dress your lawn with a thin layer (1/4 inch) in spring or fall to improve soil health. Compost tea (compost steeped in water for 24-48 hours) can be used as a liquid fertilizer. Once you start composting, you will wonder how you ever gardened without it.
