Chop greens and browns into a pile big enough to heat.
Hot compost needs enough mass; skip meats and grease in backyard piles.
Keep it like a wrung sponge; cure until dark and earthy.
Kit
- Bin or open pile space (~3×3×3 ft ideal for heat)
- Browns (leaves, chips) and greens (kitchen scraps, fresh clippings)
- Water source
- Pitchfork or aerator
- Optional second bin for curing
Do this
-
Size for heat
Aim near 3 feet of material so microbes can raise temperature. Leave room to turn.

Chop and layer
Pieces about 2 inches compost faster. Alternate browns and greens; avoid treated wood bins.

Moisture like a wrung sponge
Too dry stalls; too wet smells. Add water or dry leaves as needed.

Turn on a schedule you can keep
Weekly turning speeds warm compost (centers can reach roughly 100–150°F). Cold piles still work — just slower.

Cure and screen
Finished compost is dark with an earthy smell. Screen through 1/4-inch mesh for potting blends.
