Frequently Asked Questions

What are heirloom seeds?

Heirloom seeds are the types of seeds your grandparents grew. These varieties have been passed down from generation to generation. They’re old reliable open-pollinated varieties that aren’t typically grown commercially. Instead, they have a rich history that predates modern breeding techniques.

You can learn more about open-pollinated, heirloom, and non-GMO seeds in our Survival Garden Training blog.

How do I know my seeds are fresh?

Every seed packet includes a "packed for" date, and we germination test each seed lot before packaging to ensure you receive viable, high-quality seeds that are ready to grow.

Are your seeds treated?

No, we do not pre-treat our farmer seeds. All of our garden seeds for sale are untreated, open-pollinated, non-GMO, and heirloom varieties. They are kept in temperature-controlled cooler storage until they are packed and shipped to keep them pest and disease-free.

In what zones can I grow your seeds?

The seeds in our collections are specifically chosen from varieties that can be successfully grown from Zone 3 to Zone 10 USDA Hardiness Zones. However, individual varieties have specific needs to thrive in different environments. Each seed pack has optimal temperatures for germination and instructions on seed starting. Consult local frost dates to plan your garden and get the most out of your seeds.

What is the shelf life of these gardening seeds?

Most seeds remain viable for 3 to 5 years or longer when stored properly. Check your seed packet for specific varieties. For best results, keep your seeds in a cool, dry place away from direct sunlight and moisture. Store them in an airtight container in a consistent temperature environment—a refrigerator or cool basement works well. Proper storage helps maintain germination rates and extends seed life well beyond the packed date.

Where are Survival Garden Seeds sourced?

The majority of our seeds are sourced in the United States, with a few exceptions when the seed is difficult to source domestically. Whenever we do have to source outside of the US, we ensure our seeds are safe to grow, non-GMO varieties that meet our standards for germination and reliability.
