Frequently Asked Questions

What does USDA organic certification mean for seeds? It means the seeds were produced without synthetic pesticides or fertilizers and meet strict organic standards verified by an accredited agency.
Can I save seeds from organic plants? Yes, saving seeds from organic plants is common and encouraged to preserve organic genetics, but ensure plants were not cross-pollinated with non-organic varieties.
Do organic seeds cost more? Often, yes, because organic seed production involves more labor and certification costs, but the price difference varies by company and seed type.
Are untreated seeds the same as organic? No, untreated seeds simply haven’t been treated with chemicals but may not meet organic farming standards.
