Can I Save Seeds from Organic Produce Bought at the Store?

Choosing the Right Produce for Seed Saving

When selecting produce for seed saving, opt for organic, heirloom, or open-pollinated varieties, as these are more likely to produce consistent results. Avoid hybrid or genetically modified (GM) varieties, which often won’t produce seeds that retain their parent’s characteristics. Some popular heirloom varieties for seed saving include tomatoes, peppers, and squash.

Preparing Seeds for Storage

After harvesting seeds, dry them thoroughly to prevent mold and fungal growth. This can be done by spreading the seeds on a paper towel or cloth and allowing them to air dry for 7-10 days. Store the dried seeds in airtight containers, such as glass jars or envelopes, in a cool, dark place with low humidity. Label each container with the seed variety, date, and any relevant growing conditions.

Factors Affecting Seed Quality and Viability

Seed quality and viability can be affected by various factors, including seed dormancy, moisture levels, and storage conditions. To ensure optimal seed quality, store seeds at temperatures between 32°F and 50°F (0°C and 10°C), and maintain a relative humidity of 30-50%. Check seeds for viability by performing a simple germination test: sow a small sample of seeds in a moistened paper towel and wait for 7-10 days. If 80% of the seeds germinate, they are considered viable.
