Pro Tips

✓ A wire bin is cheapest but slowest; a tumbler is fastest but priciest
✓ Ideal ratio: 3 parts brown (leaves, cardboard) to 1 part green (scraps, grass)
✓ Turn the pile weekly and keep it damp like a wrung-out sponge
✓ Finished compost smells earthy, not rotten — if it smells bad, add more browns
