Composting for the Garden

Turn kitchen and yard waste into garden gold. Balance your pile by carbon-to-nitrogen ratio and see the CO2e you keep out of the landfill. All inputs use labeled, literature-based values.

⚖️ C:N ratio

Greens + browns → your mix C:N and what to add next.

Compost Do / Don't Checklist

  • Greens (nitrogen): vegetable & fruit scraps, coffee grounds, fresh grass, manure
  • Browns (carbon): dry leaves, straw, shredded paper, cardboard, wood chips
  • Aim for a balanced pile — roughly 2–3 parts browns to 1 part greens by volume
  • Keep the pile as moist as a wrung-out sponge and turn it for air
  • Leave out: meat, dairy, oily food, pet waste, diseased plants, weeds gone to seed
  • Chop large items and mix greens with browns as you add them
