How do you compost in a small yard?
Short answer: To compost in a small yard, use a lidded bin, tumbler, or worm bin. Add two to three times as much brown material (dry leaves, shredded cardboard) as green material (food scraps, grass). Keep it as damp as a wrung-out sponge and turn it now and then. A well-tended pile is ready in about three to five months.
What is the difference between greens and browns?
Compost needs two kinds of material. Greens supply nitrogen. Browns supply carbon. The EPA lists these examples:
| Greens (nitrogen-rich) | Browns (carbon-rich) |
|---|---|
| Fruit and vegetable scraps | Dry leaves |
| Grass clippings | Plant stalks and twigs |
| Coffee grounds and paper filters | Shredded paper (non-glossy, uncolored) |
| Paper tea bags (no staples) | Shredded cardboard (no wax, tape, or glue) |
| Crushed eggshells | Untreated wood chips |
What ratio of browns to greens should you use?
The EPA recommends at least two to three times as much brown material as green, by volume. University of Georgia Extension gives a similar split: about 2/3 browns and 1/3 greens.
In practice, for every kitchen bucket of scraps, add two to three buckets of dry leaves or shredded cardboard. The EPA also suggests covering food scraps with 4 to 8 inches of browns. That cover layer helps with odors and pests.
What should you not compost?
The EPA lists these as items to keep out of a backyard bin. UGA Extension’s list overlaps on meat, bones, dairy, oils, pet waste, diseased plants, and weed seeds.
- Meat, fish, and bones
- Dairy, cheese, fats, oils, and grease
- Cooked food (EPA)
- Dog or cat waste and cat litter
- Diseased or insect-infested plants
- Weeds with seeds, and plants treated with herbicide
- Treated or painted wood, glossy paper, produce stickers, and dryer lint
- Compostable foodservice ware and compostable bags
The EPA explains that meat, dairy, and oily foods can attract animals. It also notes that backyard piles generally don’t get hot enough to fully break them down.
What is the best compost bin for a small yard?
An open pile takes up space and can look messy. In a small yard, a contained system usually works better.
| Option | How it works | Small-yard notes |
|---|---|---|
| Enclosed bin | Lidded plastic or wood box, or a barrel | Neat footprint; a lid helps keep animals out |
| Tumbler | Drum on a stand you rotate | Easy turning; UGA Extension lists faster compost as a tumbler benefit |
| Worm bin | Worms digest food scraps in a dark, lidded box | Can often fit on a patio or in a garage; best suited to food scraps |
For rodent control, the EPA advises a lid and no gaps larger than 1/4 inch. You can buy a worm bin or build one. The EPA says untreated wood or plastic storage bins with a tight-fitting, dark lid work.
How wet should compost be?
Aim for the consistency of a wrung-out sponge. Both the EPA and UGA Extension use that comparison.
- Too dry: activity slows. Sprinkle with water and turn the pile.
- Too wet: it may smell. Mix in dry browns and turn it.
A common check: squeeze a handful. It should feel damp but drip little or no water.
How often should you turn compost?
There is no fixed schedule. UGA Extension says more frequent turning gives compost sooner. The EPA suggests using a garden fork to move outer material toward the center. If the pile is not heating up, the EPA says to add greens and turn it. With a tumbler, turning is just a few rotations of the drum.
How long does compost take?
| Method | Typical time (EPA) |
|---|---|
| Well-maintained pile, turned and balanced | About 3-5 months |
| Untended pile | Up to about a year |
| Worm bin | About 3-6 months |
The EPA also recommends a curing period. Once the pile stops heating and you can’t see food scraps, let it sit at least four more weeks before use.
Can you use fall leaves in compost?
Yes. The EPA and UGA Extension both list dry leaves as browns. Fall is the easiest time to stock up. Bag extra leaves and store them next to your bin. Through winter and spring, use them to cover each new layer of kitchen scraps. For fall lawn timing, see when to fertilize your lawn.
How do you fix compost smells and pests?
| Problem | Likely cause | Fix |
|---|---|---|
| Bad odor | Too wet or not enough air | Add browns and turn (EPA, UGA) |
| Animals digging in | Meat, dairy, or exposed scraps | Remove those items; bury scraps under 4-8 in. of browns; use a lid (EPA) |
| Rodents | Gaps in the bin | Close openings larger than 1/4 inch (EPA) |
| Pile not heating | Too few greens or too dry | Add greens, moisten, and turn (EPA) |
| Fruit flies near bin | Exposed food scraps | Cover scraps with browns (general tip); see how to get rid of fruit flies |
Wear gloves when handling compost, and wash your hands afterward.
Quick answers
Can I compost without a yard? Often, yes. A worm bin can usually be kept indoors or on a patio. The EPA says untreated wood or plastic storage bins with a tight-fitting, dark lid work.
Do compost bins attract rats? They can if they contain meat, dairy, or oily food, or have gaps. Use a lid and close any openings larger than 1/4 inch.
What is the ratio of brown to green in compost? The EPA recommends two to three times as much brown material as green, by volume.
How do I know when compost is ready? The pile has stopped heating and you can’t see food scraps. Then let it cure for at least four more weeks.
