Preparing for Harvest

Selecting the Right Time

To ensure a successful coriander seed harvest, it is important to select the right time to begin the process. The ideal time to harvest coriander seeds is when the seeds have fully matured, but before they begin to drop from the plant. This is typically about three to four weeks after the coriander plant has finished flowering. Harvesting too early may result in immature seeds, while waiting too long may cause the seeds to scatter and make the harvesting process more difficult.
