Quick Answer
Saved seeds from potted plants can perform well if the seeds are harvested from open-pollinated varieties, are stored properly, and have sufficient isolation distance from other plants to prevent cross-pollination.
Choosing the Right Variety for Seed Saving
When selecting plants for seed saving, choose open-pollinated varieties, which can be saved and replanted year after year. These varieties are bred to be stable and consistent, making them ideal for seed saving. Hybrid varieties, on the other hand, are bred for specific traits and may not produce viable offspring. It’s essential to check the seed packet or consult with the plant breeder to determine if the variety is open-pollinated.
Harvesting and Storing Seeds
To harvest seeds from potted plants, wait until the seed pods are fully dry and brittle. Open the pods and remove the seeds. Store the seeds in a cool, dry place, such as a glass jar or airtight container, with a desiccant to maintain a low humidity level. Store the seeds in a dark place, such as a cupboard or drawer, and label the container with the plant variety, date, and storage conditions. For optimal viability, store seeds at a temperature between 35-40°F (2-4°C).
Isolation Distances for Seed Saving
To prevent cross-pollination and ensure the viability of saved seeds, maintain an isolation distance of at least 10-15 feet (3-4.5 meters) between the seed-producing plant and other plants of the same variety. For larger gardens, consider creating a dedicated seed-saving area with a fence or other barrier to prevent cross-pollination. For example, if growing corn, maintain an isolation distance of at least 1/4 mile (400 meters) to prevent cross-pollination between varieties.
