How do worms get their keepers know that the compost is ready?

Worm keepers can tell that compost is ready when the material becomes dark, crumbly, and soil-like, indicating that the worms have broken down organic matter effectively. A sweet, earthy smell typically replaces any unpleasant odors, signaling that the composting process is complete. Additionally, the presence of fewer visible food scraps and a decrease in worm activity can also indicate that the compost is ready to be harvested.
