Making a DIY garbage can compost bin was one of the best gardening decisions I ever made! It’s super affordable, takes just a couple hours to set up, and gives you amazing compost for your plants. I’ve been using mine for three years now, and it still works like a charm. Diy Garbage Can Compost Bin is a popular choice for gardeners.
Living in Florida, I needed something that could handle our intense heat and humidity while keeping pests out. A simple garbage can setup turned out to be perfect because it contains everything neatly and speeds up decomposition in our warm climate.
Why Choose a DIY Garbage Can Compost Bin
I tried several composting methods before settling on this one. Open piles attracted too many critters, and fancy tumblers cost way more than I wanted to spend. A garbage can compost bin hits that sweet spot of being effective, affordable, and beginner-friendly.
The contained system works especially well here in Florida because our year-round warmth means composting happens fast. I can get finished compost in about 3-4 months, compared to 6-8 months with traditional pile methods. Plus, the lid keeps out our frequent summer rains that can waterlog open compost piles.
You’ll need just a few basic supplies that cost under $30 total. I used a 32-gallon plastic garbage can with a tight-fitting lid, a drill with various bit sizes, and some wire mesh. The whole project took me about two hours on a Saturday morning.
The best part is how low-maintenance it becomes once you get it going. I add kitchen scraps throughout the week, give it a quick stir every few days, and that’s pretty much it. No complicated ratios to remember or daily monitoring required.

Start by drilling holes all around your garbage can for airflow. I space mine about 4 inches apart in rows around the sides and bottom. Use a 1/4-inch drill bit for the side holes and a 1/2-inch bit for the bottom drainage holes. Don’t skip this step because proper air circulation prevents that gross anaerobic smell.
Next, line the inside bottom with hardware cloth or wire mesh to keep the compost from falling through the drainage holes. I learned this the hard way when my first batch started leaking out the bottom! Cut the mesh slightly larger than the can’s diameter so it curves up the sides a bit.
Drill several holes in the lid too, but make these smaller (1/8-inch) to let air in while keeping pests out. I also attached a simple handle made from a short piece of rope threaded through two holes. This makes stirring so much easier than trying to grab the lid edges.
Position your finished bin in a partially shaded spot that’s convenient to your kitchen. I keep mine near my back door so I can easily add scraps, but not so close that any odors (there shouldn’t be many) drift toward windows. Make sure it’s on level ground so it doesn’t tip over when you’re stirring.
Managing Your DIY Garbage Can Compost Bin
The key to success is balancing your “greens” and “browns” at roughly a 3:1 ratio. Greens include kitchen scraps like fruit peels, vegetable trimmings, and coffee grounds. Browns are things like dried leaves, shredded paper, and small twigs. I keep a small bag of dried leaves handy to add whenever I dump in kitchen scraps.
Stirring is super important, especially in our humid Florida climate. I use a long-handled spoon or small pitchfork to mix everything every 3-4 days. This prevents compaction and keeps air flowing through the pile. If you notice any sour smells, you’re probably not stirring enough or have too many wet greens.
University of Florida extension recommends keeping compost as moist as a wrung-out sponge. In summer, I sometimes need to add a little water if things get too dry. In our rainy season, the lid usually keeps moisture levels just right.
Watch for signs that your compost is working. You should see the volume shrinking as materials break down, and the mixture will start looking more like soil after a few weeks. The temperature might get warm in the center, which is totally normal and shows the microbes are doing their job.
Troubleshooting Common Problems
If your compost starts smelling bad, it’s usually too wet or needs more air. Add some dry brown materials like shredded newspaper and stir more frequently. I’ve found that Florida’s humidity can make this tricky, so don’t be afraid to add extra browns during our wet season.
Fruit flies can be annoying, but they’re easy to fix. Bury fresh kitchen scraps under existing compost instead of leaving them on top. I also keep a layer of dried leaves or paper on the surface, which acts like a natural cover. If flies persist, your bin might be too wet.
Sometimes the compost takes longer than expected to break down. This usually means you need more greens (nitrogen-rich materials) to feed the decomposing organisms. Coffee grounds from your local coffee shop work great, and most places are happy to give them away.
Pests like raccoons or rats are rare with a properly sealed garbage can, but if you notice signs, make sure your lid fits tightly. I use a bungee cord around mine just to be extra sure. Avoid adding meat, dairy, or oily foods that attract unwanted visitors.
Your DIY garbage can compost bin will reward you with rich, dark compost that makes your plants absolutely thrive. I love knowing that my kitchen scraps are turning into garden gold instead of heading to the landfill. Start simple, be patient with the process, and you’ll wonder why you waited so long to try composting!
