How to Start Composting in the Fall
Learn how to start composting in the fall with leaves, garden cleanup, and kitchen scraps. Simple steps to build rich soil for spring.
Why Fall is the Best Time to Start Composting
There’s something about fall that naturally lends itself to slowing down and preparing for the season ahead. While the garden winds down and the last of the summer produce is tucked away, it’s also the perfect time to start composting.
Why? Because fall offers an abundance of compost materials you won’t find any other time of year. Leaves, straw, and dried plants (called “browns”) are everywhere, while garden cleanup provides plenty of fruit and veggie scraps (“greens”). Together, they make a rich compost pile that will quietly work over the winter, giving you beautiful soil to use in the spring.
What to Add to Your Fall Compost
The best compost piles balance browns and greens. Fall just happens to give you both in abundance.
Browns (carbon-rich materials):
- Dry leaves
- Corn stalks
- Straw or hay
- Dead garden plants (without seeds or disease)
Greens (nitrogen-rich materials):
- Kitchen scraps (fruit peels, vegetable trimmings, coffee grounds)
- Fresh grass clippings
- Manure (chicken, goat, rabbit, etc.)
Bonus fall additions:
- Apple peels and cores from fall baking (think pies, crisps, or even apple scrap vinegar)
- Spent simmer pot ingredients after your home has enjoyed those cozy fall scents
- Pumpkin guts and rinds after carving or cooking

Balancing Browns and Greens
One of the most common compost mistakes in the fall is having too many leaves. While leaves are wonderful for compost, a pile made of just dry leaves will take forever to break down.
The general rule of thumb:
➡️ 3 parts brown to 1 part green.
This balance keeps your pile from getting too soggy or too dry, and it helps the microbes do their job efficiently.
If your pile feels too dry, add more kitchen scraps or grass clippings. If it’s too wet or smelly, add more leaves or shredded paper.
Setting Up Your Compost for Winter
Fall compost piles need to be built differently than summer piles because they’ll be sitting through colder months. Here’s how to set your pile up for success:
- Size matters. Aim for at least a 3×3 foot pile. Larger piles hold heat better, which keeps the composting process active even in cooler weather.
- Layer it up. Start with browns (leaves, straw), then add a layer of greens (scraps, garden waste), and keep alternating.
- Keep it moist. The pile should feel like a wrung-out sponge—not bone dry, not soggy.
- Cover it. Use a tarp or thick straw layer to insulate your pile and prevent it from drying out completely.
- Choose your container. A simple pile works fine, but you can also use a compost bin or tumbler if you prefer something more contained.
Mistakes to Avoid When Composting in the Fall
- Too many leaves. Don’t rely on leaves alone; balance them with greens.
- Letting it dry out. Even in cooler weather, your pile needs some moisture to break down properly.
- Adding diseased plants. Skip plants that had blight, mildew, or other issues—those spores can survive and spread to next year’s garden.
- Adding weeds gone to seed. Fall weeds with seeds can sprout in your finished compost come spring.
Composting in the Fall = Rich Spring Soil
Fall composting is all about looking ahead. By taking just a little time now to gather leaves, scraps, and trimmings, you’ll set yourself up for success in the spring. Instead of buying bags of soil or fertilizer, you’ll already have dark, crumbly compost ready to enrich your garden beds.
Think of it as a quiet investment in your home and land. While the world outside goes to sleep for the winter, your compost pile will be slowly working, transforming waste into nourishment.
So grab a rake, collect those leaves, and start a simple fall compost pile. Your spring garden will thank you. 🌿
