When composting without worms, you can expect the process from raw ingredients to useable compost to take about two months.
That's how long it takes for food scraps and lawn trimmings to decay without the help of worms churning the mix along.
Here's how to start home composting - no worms required - in 3 easy steps.
When your compost pile is about 3 feet high, cover it with aged manure. (Available at garden centers.) Water the pile, cover it with black plastic, and let it cook. It will get very hot inside. Turn it with a pitchfork about once a week so that everything "cooks" consistently. The more often you turn it, the faster it cooks. (If it doesn't cook, add more manure).
Continue adding garden waste, manure, table scraps, coffee grounds, eggshells, and shredded paper to your compost pile. Your compost should be fully cooked and ready to use in about two months.
