How to Start Composting this Fall

Fall creates one of the easiest opportunities to start composting.

Leaves are falling. Gardens are being cleaned out. Plants are being cut back. Instead of treating all of that material as waste, you can begin turning some of it into something useful for next year's garden. And you don't need an expensive composting system to begin. At its simplest, composting is helping natural decomposition happen in a way that eventually gives you a useful soil amendment. University of Idaho Extension describes composting as a natural biological process that turns materials such as leaves, grass, and plant material into a soil-like material that can return organic matter and nutrients to the soil. That's one reason fall can be such a good time to start.

Start With a Simple System

Your first compost system doesn't need to be complicated. Depending on your space, that might mean a basic compost bin, a contained pile, or another simple backyard setup. The important thing is choosing something you can actually maintain. If you've never composted before, I wouldn't worry about building the perfect system. Start by learning how the materials behave.

Learn Browns and Greens

One of the basic ideas behind composting is balancing carbon-rich and nitrogen-rich materials. Browns can include things like dry leaves, straw, shredded paper, and woody material. Greens can include grass clippings, vegetable scraps, coffee grounds, and fresh plant material. You may see precise carbon-to-nitrogen ratios when you start researching composting. Those ratios matter scientifically, but you don't need to stand beside your compost pile doing chemistry. Precise recipes sometimes aren't practical for most backyard composters. A useful starting approach is roughly one to three volumes of browns for every one volume of greens, then adjust based on how your pile behaves.

Don't Forget Air and Moisture

Your compost also needs oxygen and moisture. The material should be damp without being waterlogged. I have looked at many resources that recommend a simple squeeze test: composting material should feel damp, but shouldn't freely drip water unless squeezed tightly. Turning or mixing the pile periodically introduces more air. If your pile becomes wet and smelly, adding dry brown material and improving airflow can help. If it's extremely dry and decomposition has slowed, moisture and additional green material may be needed.

What Should Stay Out?

A beginner compost pile shouldn't become a dumping ground for everything biodegradable. For a typical backyard system, avoid materials such as meat, dairy products, oils, pet waste, and diseased plants. These can create odor, pest, pathogen, or other management problems. This is another reason I like starting simple. You can always learn more advanced composting methods later.

What Happens During Winter?

If you're starting in the fall, don't be discouraged when colder weather arrives. Your pile may slow down substantially as temperatures fall. That doesn't mean you've failed. OSU Extension notes that composting can continue through winter, although the process slows. Keep adding appropriate materials when practical, maintain reasonable moisture and airflow, and let the process work. You're building a system, not racing a clock.
