Step 2: Hold a Seed Stalk

Now, hold a seed stalk with one hand. Gently pinch the stalk just under the seedhead with your other hand (holding it between your thumb and forefinger).

Step 4: Move on to the Next Stalk

Now, move on to the next stalk, grasp it, and harvest the seeds with your fingers. continue harvesting the seeds from the heads until you have harvested enough grass seed to suit your purpose.
