Building Hot Compost in 6 to 12 Weeks
title: "Building Compost: Hot Method in 6-12 Weeks"
Most backyard composting is cold composting: pile up leaves and grass clippings, check back in 12 to 18 months, and find partially finished material. Cold composting requires almost no effort. It also won't kill weed seeds or disease pathogens, and it takes a long time.
Hot composting reaches 131 to 160°F in the pile's core, which kills weed seeds and most plant pathogens. A properly managed hot pile can produce finished compost in 6 to 12 weeks. It requires more management — maintaining the right carbon-to-nitrogen ratio, adequate moisture, and turning on a regular schedule.
