Annual Seed Exchange

Annual Seed Exchange

The annual Seed Exchange is an opportunity for Cal Hort members to share their plants. Participation in the Seed Exchange is a benefit of membership; to receive seeds, you must be a current member of Cal Hort.

Timeline:

September–November: Members submit properly prepared seeds collected from their gardens. If you plan to submit seeds that ripen later send Dave a list so he can prepare for the.
January: A list of the donated seeds with a request form is made available to members.

February: Completed request forms along with $5 for supplies and postage must be received by the end of the month.
March: Seeds are distributed by mail.

If you would like to help with cataloging and mailing the seeds please email us at calhortinfo@gmail.com and type “Volunteer” in the subject line.

Basic Steps for Preparing Your Seeds for Sharing:

  • Allow flowers or seed pods to ripen on the plant until they are dry and starting to brown.
  • Separate the seeds from surrounding plant material—petals, pods, leaves, stems. You can use a plastic bag to shake the seeds into but do not store the seeds in plastic as they can mold.
  • Spread the seeds out to dry.
  • Collect the seeds in a paper envelope or other paper wrapping and write the plant name on the outside. Do NOT send or store seeds in plastic.
