Book 29, Question 106
How do you know compost is finished?
Finished compost is dark brown, crumbly, and smells fresh like a forest floor.
You can't tell what the original scraps were, except maybe for a few eggshells or twigs. It's cool to the touch. Gardeners often sift it. Unfinished compost can be too strong and hurt seedlings, so it pays to wait. Then spread it on beds or mix into potting soil.
