Frequently Asked Questions
What does certified organic seed mean? Certified organic seeds are grown without synthetic pesticides, herbicides, or genetically modified organisms and meet USDA organic standards verified by accredited agencies.
Are all heirloom seeds organic? No, heirloom seeds are open-pollinated and historically preserved varieties but are not necessarily grown organically or certified as such.
Can I save seeds from organic plants? Yes, saving seeds from organic plants helps preserve genetic diversity and supports sustainable gardening, but ensure plants are open-pollinated to maintain true-to-type traits.
Why choose organic seeds over untreated seeds? Organic seeds come from plants grown under organic standards, which can better support certified organic gardening, whereas untreated seeds may not be grown organically but lack chemical treatments.
Do organic seeds cost more? Generally, yes. Organic seeds often have higher production costs due to certification and farming practices, but they offer assurance of compliance with organic standards.
Can I grow organic vegetables from non-organic seeds? Yes, but to maintain organic certification for your crops, seeds must be organic unless unavailable; using certified organic seeds is preferred for certified organic production.
