Short answer: A compost pile for beginners can be one open pile in a back corner of the yard. Bury your kitchen scraps in it, cover them with leaves or old straw, and never turn it. After a year of adding, stop and let it sit for another year, then spread it on the garden. No math, no thermometer.
One corner, a few cinder blocks, and a pile of leaves. That's the whole setup.If composting sounds smelly, fussy, or like a science project you'll get wrong, you're in good company. Most guides hand you a ratio to hit, a temperature to check, and a schedule for turning the pile. You don't need any of that to make good compost. You need a corner, some leaves, and patience.
We've kept an open compost pile in cinder blocks at both of our houses: our old quarter-acre place inside the Baltimore Beltway, and the 1920s house we rent now. We used to check ours with a thermometer. These days we never turn it, and we let every batch sit a full year before we use it.
Here's the smallest version that works, what goes in, how to tell when it's done, and what to do if you don't have a yard corner at all.
Pick a spot that's out of the way but still easy to reach with a container of scraps. You'll walk there a lot, and you'll want to.
The spot you choose will get better too. After we moved the Beltway pile, we planted a pair of Chinese chestnut trees. One went right where the compost had been. That tree grew taller faster than the other one and produced more chestnuts.
Our compost pile at the old Beltway house. Cinder blocks hold it in, no mortar needed.You only need one pile your first year. The second one comes later, once the first is full.
That's all. No bin to buy, no thermometer, no special tools.
Before we had chickens, we kept a small container on the kitchen counter and dumped it on the compost pile. Now most of our food scraps go to the chickens. We keep one small container for chicken treats and a small foot-pedal garbage can for everything else, like onion skins and orange peels.
We try to empty both every day. In summer, you'll know you're waiting too long if you see maggots in the compost. Empty more often, and bury the fresh scraps under the leaves.
Most guides say to turn your pile with a fork every few weeks so it breaks down faster. We never do. Sometimes we dig in to bury something deeper, and that's it. Ours isn't as wise as Marjory the Trash Heap from Fraggle Rock, but it does a lot of good just sitting there.
The tradeoff is time. Turning speeds things up, and skipping it means waiting longer. WVU Extension's article on Composting for Beginners notes that a pile you don't turn will still turn into finished compost, just more slowly. We'd rather wait than turn it.
Many guides, including WVU Extension, say to keep meat, greasy food, and dairy out of backyard compost. We don't. We compost ours or feed them to the chickens, because sending them down the drain or to the trash isn't a better answer. The key is burying them deep in the middle of the pile.
If you're brand new, start with plant scraps and leaves for the first few weeks. Wait until the pile is deep enough to bury things well before you add meat or dairy. Then follow the same habits that keep the pile safe: wear gloves when you work in it, wash your hands afterward, and let it sit for a full year before you use it.

We keep rabbits, and their manure is one of our best garden boosters. It doesn't go in the compost pile. We let it dry and pile up on its own for about six months, then use it to refresh our raised beds and GreenStalks. If you don't keep rabbits, skip this part. Your compost pile is plenty.
This is the part that makes our pile so low-effort. We have two bays side by side in the cinder blocks. One bay is the one we're adding to. The other is sitting and aging.
After that, the two bays just take turns. Every spring, one bay is ready to use, and the other becomes the one you're filling.
We used to check our pile with a thermometer to make sure it got hot enough to kill weed seeds. Now we're confident that a full year gives it time to heat up and break down. If you'd like to check yours anyway, a thermometer is fine. You just don't need one to start.
For us, the calendar decides. Once a bay has sat for a full year without anything new going in, it's ready the next spring.
You'll also see it. The pile shrinks a lot as it breaks down. Finished compost looks, feels, and smells like healthy soil. If you dig in and still find lots of recognizable scraps, give it a few more months.
Our compost pile now. The wire across the front of the active bay keeps our dog out.In spring, we shovel out the aged bay. The compost goes into our raised beds and flowerbeds, and into the hole with any tree or other plant we put in the ground. We also fill bare spots and holes in our pastures with it. Then that bay starts over as the new pile.
Most compost problems are small and easy to fix. These are the ones we've run into, plus a couple you're likely to wonder about.
You'll see worm bins recommended everywhere for small spaces, so here's how ours went.
At the Beltway house, we kept composting worms in a plastic tub in the basement. It developed mold, and we didn't enjoy the chore of cleaning it out to harvest the castings. Then we got busy with other projects and let it go. We've also tried spare large flowerpots with a newspaper on top. That was easy and cheap, but it dried out faster and was harder to harvest from.

A worm bin can work for someone without a yard who enjoys tending it. If you mostly want your scraps out of the trash with as little effort as possible, the outdoor pile, or a drop-off program, will be easier.
An open pile needs a patch of ground. If you're on a balcony, in an apartment, or renting without a yard, you still have good options. None of them make you less of a homesteader.
Ask your landlord. Ours said yes, and the only thing we had to settle was where it would go. Come with a spot in mind, away from the house and the fence lines, and offer to keep it neat in cinder blocks.
Some cities and counties collect food scraps at drop-off sites, often at farmers markets or public works yards, and turn them into compost. Montgomery County, Maryland, for example, lists drop-off locations for food scraps recycling around the county.
To find one near you, search your city or county website for "food scraps" or "compost drop-off." Rules vary, and some sites don't take meat or dairy, so check what yours accepts. Not every area has one. Ours doesn't, as far as I know.
Some places have rules for backyard composting, such as requiring a closed bin for food scraps. Check your city or county before you build.
A worm bin fits indoors, but read about how ours went before you buy one.
You don't need compost to start growing. A few pots on a patio or steps can give you real food this season. See Container Gardening for Beginners.
Once your pile is started, pick the next small step that fits your space.
A compost pile is one small system. If you're wondering which one to start next, whether it's food, water, or home comfort, my free 2-page guide helps you pick one place to start. It's called Which Urban Homestead System Should You Start First?, and it's built for small spaces and busy lives.
Do I have to turn my compost pile?
No. We never turn ours. A pile you don't turn still becomes compost, it just takes longer. We let each bay sit a full year after we stop adding to it.
Do I need a compost bin?
No. We use an open pile held in with cinder blocks, and we've never used a closed bin or a tumbler. Some places require a closed bin for food scraps, so check your local rules.
Will a compost pile smell?
Ours doesn't bother us. It sits far enough from the house, and we cover every addition with leaves, straw, or old hay. If yours smells, bury the food deeper and add more on top. Odor can be sign that you need to add more carbon like leaves, straw, old hay, or wood shavings.
Can I put meat and dairy in compost?
We do, buried deep in the middle of the pile, and we let it sit a full year before using it. Many guides say to keep them out. If you're new, start with plant scraps until the pile is deep enough to bury things well.
How long until the compost is ready?
For our pile, about two years from the first scraps: one year of adding, then one year of sitting. After the first round, one bay is ready every spring.
Do I need a thermometer?
No. We used one for years, and now we let time do the work instead. A full year of sitting gives the pile time to heat up and break down.
Can I compost without a yard?
An open pile needs ground. Without a yard, look for a food scrap drop-off program near you, or try a worm bin if you'll enjoy tending it.
