About Wehmeyer Seed Company

Independent. Family-owned.

Committed to delivering high quality seed and a high quality experience.

Family-Owned and Operated.

Dale and Lisa Wehmeyer founded Wehmeyer Seed Company in 1995. What began as a small seed conditioning operation has grown into a multigenerational family business based in Mascoutah, Illinois.

Our roots in seed production and conditioning shape how we serve customers today. We understand the work behind a quality bag of seed, and we believe the experience you have with our company should reflect that same care.

High Quality Seed. High Quality Experience.

For us, that means every bag of seed exceeds the industry’s seed quality standards and paying attention to the people planting it. You can call company leadership to communicate your needs. We are here to support you.

Plus, we have one of the industry’s best seed treatments, providing the highest level of disease, insect, and pathogen control.
