Harvesting Your Vermicompost
There is no exact point in time when the bottom processing tray is ready to be emptied, but it generally takes 3-4 months to complete the first tray. Once you have multiple processing trays working at one time and your worm population has increased, you should be able to harvest compost about once a month, although this varies. When the material is nearly black and the chunks of matter are small and crumbly, your compost is ready to be harvested.
*Finished Compost should be dark, crumbly, and moist, like used coffee grounds.
