Make Your Own Organic Compost: Ingredients, Layering, Timeline & Equipment

Homemade compost beats store-bought: free, custom, alive. Here's the complete method.

Ingredients: What Goes In

Greens (Nitrogen): fruit/veg scraps, peels, cores, coffee grounds, tea bags, grass clippings, fresh plant trimmings, herbivore manure.
Browns (Carbon): dry leaves, straw, shredded cardboard/newspaper, sawdust (untreated), wood chips, pine needles.
No: meat, dairy, oils, cooked food, pet waste, diseased plants, seeded weeds, glossy paper.

Build the Heap

1. Dig pit or use bin (3×3×3 ft minimum for heat).
2. Base: 6" coarse browns (twigs, corn stalks) for airflow.
3. Layer: 4–6" browns, 2–3" greens, 1" soil/compost starter. Repeat.
4. Water each layer: damp sponge consistency.
5. Cover: tarp or lid (moisture + heat retention).

Maintain & Harvest

• Turn weekly with fork—introduces oxygen, mixes, checks moisture.
• Add water if dry; browns if soggy/smelly.
• 2–3 months: dark, crumbly, earthy. Screen (½" mesh) for fine compost.
• Return coarse bits to next pile.

Equipment Options

Tumbler: easy turning, faster, rodent-proof. 3-bin system: continuous flow. Simple heap: free, works. Worm bin: kitchen scraps only, castings in weeks.

Boost (Optional)

Add rock minerals (greensand, phosphate) or finished compost as "starter." Not required.

Your waste, your gold, your garden's foundation.
