4th Generation Family-Owned Business


GS3 Quality Seed Inc. is owned by Garth and Susan Mulkey. They are fourth-generation seed farmers in the Willamette Valley of Western Oregon and have been growing, conditioning and marketing seeds at the same location since 1966. As dedicated seed producers, they are always focused on seed purity and quality, combined with proven genetics.


Garth and Susan have been no-till farming for 23 years and know firsthand the benefits of planting radishes and other cover crops. Even in seed production fields, radishes provide the same great benefits as they do for row-crop producers.


The GS3 Difference

GS3 Quality Seed prides itself on honesty, fairness, high-quality seed, economical prices, and exceeding your expectations.
