When the garden is frozen and everything feels still, your compost pile doesn’t have to be.
Composting in cold weather might sound like a lost cause, but with a few simple tweaks, you can keep your scraps breaking down all winter long. Whether you’re composting to reduce waste, build spring soil, or just stick to your homestead values, these winter composting tips will help you do it successfully, even in cold climates.
Why Compost in Winter?
Let’s be honest, it’s tempting to pause composting when everything slows down.
But here’s the thing:
- Your kitchen scraps don’t stop just because it’s cold.
- Keeping your pile going prevents frozen food waste from piling up indoors.
- Winter prep gives your pile a head start when spring warms things up.
Bonus: Compost adds heat to your soil when applied in spring. That’s a win-win for early planting.
1. Use a Smaller, Tighter Bin
In cold climates, a compact pile holds heat better than a sprawling one.
Choose or build a bin that:
- Has insulated or thick sides (think pallets, straw bales, or heavy plastic)
- Has a lid or tarp to keep out snow and rain
- Sits directly on the ground (if possible) for microbial activity and drainage
GROWING TIP: An old trash can with drilled holes works great in a pinch.
2. Chop Your Scraps Small
Smaller pieces mean faster breakdown.
In winter, decomposition slows naturally, so help your pile along by:
- Chopping veggie scraps before adding
- Breaking down cardboard or paper
- Crushing eggshells
A little prep makes a big difference in cold weather composting.
3. Balance Browns and Greens (Even Now)
Just like in summer, you’ll want to aim for a good ratio of:
- Greens: fruit and veggie scraps, coffee grounds, fresh plant matter
- Browns: dried leaves, shredded paper, straw
Too many greens in cold weather can turn your bin into a soggy, frozen mess. Keep a stash of browns nearby to layer with every kitchen dump.
NOTE: Avoid adding meat, dairy, or anything oily. These don’t break down well in the cold and can attract critters.
4. Add Heat Where You Can
Winter composting doesn’t require a heat lamp, but you can encourage warmth:
- Layer with fresh manure (from chickens, rabbits, etc.)
- Add hot water bottles or jugs wrapped in towels (if in a closed bin)
- Move the bin to a sunnier spot
- Cover the top with a tarp or extra straw
Even a small temperature bump helps microbes stay active.
5. Turn Less, Insulate More
Turning your pile introduces air, which is good, but in winter it can also let precious heat escape.
Try this:
- Turn the pile only if it’s not frozen and feels too wet or compacted
- Otherwise, leave it be and insulate with straw, cardboard, or even a blanket
Let it rest. Nature still works in the cold, just more slowly.
6. Store Scraps Smartly
If snow or ice makes your bin hard to reach, keep a sealed bucket or container near the kitchen (garage or porch) and empty it during warmer spells.
Some folks even keep a freezer bin for scraps. No smell, no mess, and easy to add to the pile when the time is right.
Composting Through the Cold is Totally Doable
Winter composting in cold climates takes a little extra intention, but it’s 100% worth it. With the right setup and habits, you’ll turn your winter kitchen waste into a springtime soil boost.
Start small. Keep it simple. Trust the process.
Frequently Asked Questions About Winter Composting
Q: Can you compost in the winter?
Yes. Composting in winter is completely possible if you keep your pile insulated and balanced. Microbes slow down in cold weather, but they do not stop working. Focus on smaller scraps, good airflow, and insulation to keep the pile active until spring.
Q: What is the best compost bin for cold climates?
The best bin for cold climates is one that retains heat and blocks wind. Insulated plastic bins, enclosed tumblers, or DIY bins made from straw bales or pallets work very well. A tight-fitting lid keeps snow and rain from soaking your pile.
Q: Should I turn my compost pile in winter?
Turn it only when the pile is not frozen and feels compacted. Turning adds oxygen but can also release heat, so less is more during cold months. Focus on keeping the pile insulated and moist instead of turning frequently.
Q: What can I compost in winter?
You can compost the same materials as in summer. Stick to fruit and vegetable scraps, coffee grounds, tea bags, and shredded paper. Avoid meat, dairy, and oily foods, since they do not break down well in the cold and may attract animals.
Q: How do I keep my compost from freezing?
Insulate the pile with straw, cardboard, or old blankets, and cover it with a tarp to trap heat. If possible, place the bin in a sunny spot or near a building for wind protection. A thick layer of browns on top also helps hold warmth.
Q: Can I start a compost pile in winter?
Yes, but results will be slower until temperatures rise. If you start in winter, build your pile with extra insulation and add greens and browns gradually. Once spring arrives, the existing material will heat up quickly and break down faster.
Q: How do I store kitchen scraps when it is too cold outside?
Keep a sealed bucket, compost pail, or container in the garage or porch, and empty it into your outdoor bin during warm spells. Many homesteaders also freeze scraps until they can be added to the compost pile. This prevents odors and saves trips through snow or ice.
