Frequently Asked Questions
Are all seeds labeled organic truly organic?
Only seeds certified by USDA Organic or equivalent third-party organizations are guaranteed organic. Some companies may offer seeds grown using organic methods but lack certification, so always check labeling carefully.
Can I save seeds from organic plants to reuse?
Yes, saving seeds from organic plants is encouraged and can be done effectively, especially with open-pollinated and heirloom varieties. Hybrid seeds may not breed true, so seed saving is less reliable for hybrids.
Do organic seeds cost more than conventional seeds?
Typically, organic seeds are more expensive due to the costs of certification and organic farming practices, but prices vary widely by company and seed type.
Are hybrid seeds available as organic?
Yes, some companies offer organic hybrid seeds, but they are less common than open-pollinated varieties. Organic certification applies to how seeds are produced, not their genetic type.
How important is seed origin for organic gardening?
Seed origin matters because locally adapted seeds often perform better in your climate and soil conditions, reducing the need for interventions and supporting organic principles.
Can I trust non-certified organic seeds?
Non-certified organic seeds may be grown using organic methods but without official oversight, so trust depends on the company’s transparency and reputation.

Choosing the right mail order seed source for organic seeds depends on your gardening goals, location, and commitment to organic integrity. Companies like High Mowing Organic Seeds and Johnny’s Selected Seeds stand out for their certified organic selections and sustainable practices.
