Composting Basics: The Slow Pile That Actually Works
Greens, browns, water, air — four inputs. A pile, not a science project. The home-scale method that finishes in 6–9 months without thermometers or activators.
Composting is a pile of kitchen scraps and yard waste, kept moist and aerated, that finishes into dark soil amendment in 6 to 9 months. You need four inputs: greens (nitrogen-rich), browns (carbon-rich), water, and air. A 3-parts-browns to 1-part-greens ratio is the only number worth memorizing. Skip the activators; you do not need a thermometer.
What composting actually is
Composting is the controlled rot of organic matter into a stable, soil-like amendment that gardeners call humus or finished compost. The decomposition is done by fungi, bacteria, worms, and insects — you are not making the compost; they are. Your job is to feed them the right materials and keep them comfortable.
