Grass seed is ready to harvest when it heads start to shatter (i.e. are drying out and fall off in your hand). Harvest seed from at least 10-20 plants, if possible.

Cut stems at least 2-3 inches below the bottom of the seed head. Be careful to ensure that the seeds don't fall out.

Place all of the seed heads into coin envelopes, manila envelopes, or paper bags. Store in a cool, dry place so the plant tissue dries down completely.

Mail or personally deliver the samples to UC Davis at the following address:
