Seed Threshing

• After harvest, seeds are threshed to remove the seed from the surrounding plant material.
• A period of air-drying is important before seeds are threshed.
• Plant material should be spread out in thin layers until all plant material is dry; otherwise, mold, decay, and heat from decay will cause damage to the seeds.
• As the plant material dries, seed pods may split open or shed seed.
• Plant material that is ready to be threshed should be brittle.
