Hot Composting

Hot composting builds a pile big enough and balanced enough to heat to 130–160°F as microbes work. At that temperature it breaks down in weeks rather than months and kills most weed seeds and pathogens.

It's the fastest way to turn yard and kitchen waste into rich compost, and the heat produces a cleaner, weed-seed-free product. A finished pile feeds your beds and closes the loop on garden and kitchen waste.

Aim for a pile at least 3x3x3 feet so it can hold heat. Mix roughly 2–3 parts "browns" (dry leaves, straw, cardboard) to 1 part "greens" (food scraps, fresh grass, prunings). Chop materials small and dampen each layer like a wrung-out sponge. Turn the pile every 1–2 weeks to add air. When it stops heating and looks dark and crumbly, it's ready.

If it smells bad or stays cold, it's usually too wet/too many greens (add browns and turn) or too dry (add water). Keep meat, dairy, and oils out. A pile that's too small won't heat — bulk is what holds the warmth.
