How to Make a Simple Compost Bin | Three DIY Builds That Work

Guide / By

A simple compost bin needs just four things: airflow, drainage, browns, and greens. Build one from a plastic tote, wire fencing, or pallets.

Making a simple compost bin is one of the fastest wins in the garden, and you probably have most of what you need already. Whether you want to keep kitchen scraps out of the trash or feed your soil without buying fertilizer, the core design stays the same: give the pile airflow and drainage, start with a layer of browns, add greens, and keep everything moist but never soggy. Here are the three simplest builds that actually work.

What Is The Easiest Simple Compost Bin To Make?

A plastic storage tote is the easiest option. It needs about an hour of your time, a drill, and a container with a tight-fitting lid roughly 24 inches tall. This build works well on a patio, balcony, or tucked behind the garage.

Drill 8–10 small holes in the bottom and another 8–10 holes in the lid for airflow and drainage. Fill the bin about one-eighth to one-quarter full with shredded newspaper or dry leaves, then add dirt until the container sits half full. Add food scraps or paper products, stir, and cover the scraps with dirt. Spray with lukewarm water until the pile is moist—think a wrung-out sponge, not a soaked one—then put the lid on and keep the bin in a shady spot away from the house. Turn the contents weekly with a hand fork to keep air moving. When the material turns dark and crumbly, it’s ready.

One caution: use a shallow, durable plastic container and keep the holes near the top if you’d rather not drill the bottom. The same rule applies—alternate green and brown layers and keep the moisture level steady.

How To Build A Wire-Fence Compost Bin For Under $30

A wire-fence bin is the cheapest way to compost at scale, and it takes about 20 minutes to assemble. You need coated wire fencing with 2 x 3-inch mesh, a few rebar stakes, and either twine or flexible wire to secure the ends.

Unroll enough coated fencing to form a circular enclosure—about 4 to 5 feet wide works well. Cut the length you need, bend the ends together, and fasten them with non-biodegradable twine or flexible wire. Pound the rebar stakes into the ground around the outside to hold the structure steady. Wear leather gloves for this step.

Larger mesh openings let material escape, so don’t substitute a wider grid. The 2 x 3-inch mesh keeps the pile contained while still letting air reach the center.

What Browns And Greens Do You Add, And In What Ratio?

Compost needs two ingredient types: browns for carbon and greens for nitrogen. Common browns include dry leaves, newspaper, straw, wood chips, twigs, and wood shavings. Greens include food scraps and other nitrogen-rich kitchen and garden waste. A beginner-friendly target is roughly 50% greens and 50% browns by volume. Some DIY builds prefer a 2:1 ratio of browns to greens—either works as long as you keep the pile from getting soggy.

The EPA’s guidance for backyard piles is to start with a four- to six-inch layer of bulky browns like twigs and wood chips. That base lets air move through the pile from underneath. For the pile to reach the temperature needed for active decomposition, aim for roughly one cubic yard—about 3 x 3 x 3 feet.

Do not add animal waste, meat, or dairy products to a basic backyard bin. These attract pests and create odor problems that are hard to reverse. Keep those materials for a more managed system.

Making Compost Work — And Fixing It When It Doesn’t

The most common mistake is overwatering. Soggy compost smells and breaks down slowly. The fix is simple: add more browns and turn the pile. If it’s too dry, spray the surface with water until it feels like a damp sponge. If it attracts flies, bury the food scraps under a few inches of browns.

Turning frequency depends on the build. A tote benefits from a weekly stir. A wire bin needs turning less often, but a pitchfork pass every two weeks speeds things up considerably. Place the bin in a shady area away from the house to keep moisture levels even and reduce odor near your living space.

Build Type Materials Needed Best For
Plastic storage tote Tote with lid, drill, dirt, shredded paper or leaves Small spaces, patios, beginner composters
Wire-fence bin Coated wire fencing, rebar stakes, twine or wire ties Large volume, backyard piles, low cost
Wood pallet bin 3–4 pallets, zip ties or screws Gardeners who want a sturdy permanent structure

Finished compost takes anywhere from two months to a year depending on your mix, moisture, and turning frequency. When the material is dark, crumbly, and smells like earth, it’s ready to work into garden beds or top-dress your lawn.

FAQs

Should I put worms in a simple compost bin?

Standard outdoor piles will attract worms on their own as the material breaks down, and that’s a good sign. You don’t need to add them. For an indoor tote that stays in the house, a separate worm composting setup uses a shallow bin with worms working the top layer—a different method than outdoor composting.

Can I compost weeds and grass clippings from my yard?

Yes, but mix them well so they don’t mat together. Grass clippings are nitrogen-rich greens, so pair them with dry leaves or straw. Avoid adding weeds that have gone to seed unless your pile heats up actively; most simple bins never reach that temperature, so seeds may survive.

How long until a simple compost bin produces usable compost?

With regular turning and the right moisture level, a wire bin can produce usable compost in three to six months. A plastic tote runs slower because it holds less volume—expect six months to a year. Hot, sunny placement speeds things up, but keep the bin out of direct sun if it’s plastic, since heat can dry the pile out fast.
