Harvesting and Saving Heirloom Seeds

  • GHCL Annex 7306 Southwest Oleson Road Portland, OR, 97223 United States (map)

Join OSU Master Gardener Sarah Gramm Wolf in a hands-on approach to harvesting and saving heirloom seeds. Learn when to harvest, wet and dry methods of cleaning, drying, and storing seeds for maximum viability, and do-it-yourself viability testing before planting your saved seeds. Pioneers brought their saved seeds with them when they crossed the Oregon trail... the tiny, mighty seed!

Leave this 1.25 hour event with seeds you can plant as well as multiple handouts to document your saved seeds for sharing, resources for heirloom seeds, references for growing and saving your favorite seed, plus online classes for seed saving, starting a seed library, and more.

For adults, teens, and tweens age 10+. This program is free but seats are limited. Please register at or 503-215-9932.
