Quick Answer
To collect seeds from fruit, harvest ripe seeds from open-pollinated fruits, dry them thoroughly, and store them in a cool, dark place. It's essential to label and date the seeds, and to maintain isolation distances to prevent cross-pollination. This ensures the viability and genetic integrity of the seeds.
Preparing Seeds for Storage
When collecting seeds from fruit, it’s crucial to choose open-pollinated varieties, as these can be saved and replanted with predictable results. Hybrid seeds, on the other hand, may not produce seeds that retain their parent’s characteristics. Once you’ve harvested the seeds, dry them thoroughly to prevent mold and rot. This can be done by spreading the seeds on a paper towel and allowing them to air-dry for 2-3 days.
Isolation Distances and Cross-Pollination
To maintain the genetic integrity of your seeds, it’s essential to maintain isolation distances between your open-pollinated plants and other plants of the same species. This means growing your plants at least 1-2 miles away from other plants of the same type, or using physical barriers like screens or bags to prevent pollinators from transferring pollen. For example, if you’re growing a variety of tomato, keep it at least 1 mile away from other tomato plants to prevent cross-pollination.
Storing Seeds for Viability
Once your seeds are dry and cleaned, store them in a cool, dark place like a glass jar or airtight container. Label the container with the date, the variety name, and any relevant notes about the seeds. Store the seeds in a location with a consistent temperature between 35-45°F (2-7°C), and keep them away from direct sunlight and moisture. For optimal viability, store the seeds for no more than 5 years, and check on them regularly to ensure they remain viable.
