Most people are under the impression that composting ceases when the cold sets in. You put your container away in the garage, feel bad for throwing banana peels into the trash, and promise yourself that you will start over in the spring.
Yet December 2025 is showing that maybe winter is actually the best season for composting, especially with simple winter composting methods that work even in cold months.
I am not saying this is a complex system that requires a microbiology degree. These are feasible ways that work even during snow days.
And the timing is crucial because the food waste we generate this winter will determine the methane emissions that are happening at this very moment.
It is my best find this winter. Hot composting is achieved by generating sufficient internal heat in the heap, allowing it to continue breaking down even in very cold conditions outside.
The secret is getting the right mix of materials and making a heap large enough to produce heat.
This is one of the strongest winter composting methods because it keeps decomposition active.
You are to have a mixture of “greens” (food scraps, fresh grass clippings) and “browns” (dry leaves, shredded paper, cardboard).
The ratio is approximately three parts brown to one part green. When you heap them in a pile that is at least three feet cubed, the decay process heats the pile – sometimes even up to 140°F in the center.
According to research by the EPA, proper composting can lead to the saving of up to 30% of household waste from landfills
This is a lot when you take into account the amount of waste that is caused by Americans during the holiday season.
I got my hot pile going at the beginning of December, and even with nights being in the 20s, the center is still warm enough to produce steam upon turning it. Truly one of the winter composting methods that surprises people.
The Trench Method
It’s almost embarrassingly straightforward. You dig a trench in your garden bed, throw in your food scraps, and then cover them with earth.
The waste dissolves underground over winter, and thus, by spring, you have rich soil for your plants. This is why many gardeners rely on trenching as part of their winter composting methods.
The brilliance of winter trench composting lies in the fact that frozen ground slows decomposition just enough to avoid odors while still allowing beneficial microbes to be active. Besides, you are putting nutrients right where you will need them when the growing season arrives.
I have been moving the trenches on my garden beds. Each week I dig in a different place. By March, the whole area of my garden will have been fertilized.
Indoor Vermicomposting
Worm bins are strange until you try them. Red wiggler worms can be considered happy residents of a plastic bin under your sink or in a closet, where they eat your food scraps and produce extremely rich compost called worm castings.
Among all winter composting methods, this is perfect for people living in apartments or extremely cold regions.
If you maintain these systems properly, they do not emit odors. The main thing is not to overfeed and at the same time keep the bedding moist but not wet.
Worms do not like citrus and onions, but they will happily consume coffee grounds, vegetable scraps, and even shredded paper.
My worm bin has been operational since Thanksgiving, and I am really impressed by the amount of waste these small creatures can handle. A pound of worms can consume roughly half a pound of food scraps per day.
The Bokashi Bucket
This Japanese method changes food waste into fermented products instead of rotting them in the usual way.
You have a special bucket with a tight lid into which you put the food scraps, after which you sprinkle them with bokashi bran (which contains beneficial microbes) and close the lid.
The fermentation process is anaerobic, that is, it works without the presence of air. Therefore, it is ideal for winter that the bucket can be kept in a garage or basement where it is not freezing.
After two weeks, you can bury the fermented waste in your garden or spread it in a regular compost pile. Bokashi is becoming one of the increasingly popular winter composting methods because of its flexibility.
What is the greatest thing? Bokashi is capable of handling things that a normal compost can not, such as meat, dairy, and cooked foods. Flexibility is what matters during the holiday season when you have leftovers of everything.
The Lazy Pile
Not all methods have to be optimized. Sometimes the only thing you can do is make sure that no organic matter ends up in the trash.
A simple outdoor pile where you throw your scraps and allow them to decompose slowly is good enough and still counts as one of the easier winter composting methods for beginners.
It will not be finished compost by spring but it is still better than sending everything to a landfill. Research shows that even slow composting can lower greenhouse gas emissions by 50% as compared to landfilling organic waste.
I have a “lazy pile” behind my shed where I put things that do not match my hot composting ratio or when I am too busy to carry out the method properly.
