How Often Should Saved Seeds Be Checked for Viability?

Seed Storage Conditions

Proper storage of saved seeds is crucial for maintaining their viability. Store seeds in a cool, dry, dark place, like a basement or a climate-controlled storage room, with a consistent temperature between 32°F to 40°F (0°C to 4°C). Maintain a relative humidity below 50% and keep the seeds away from direct sunlight and moisture.

Seed Testing Methods

There are several methods to test seed viability, including the cold water test, the seedling test, and the germination test. For a cold water test, place 10-15 seeds in a cup of cold water. If 8-10 seeds float within 24 hours, they are likely viable. For a seedling test, sow 10-15 seeds in a pot and observe their germination rate after 7-10 days. A germination rate of 80% or higher is considered acceptable. The germination test involves sowing 10-15 seeds in a controlled environment, like a propagation tray, and monitoring their germination rate after 7-14 days.

Seed Viability and Renewal

It’s essential to regularly check saved seeds for viability to ensure they remain suitable for planting. Renew seeds every 2-3 years to maintain genetic diversity and prevent degradation. When renewing seeds, replace old seeds with new ones from the same variety, and store the new seeds in a separate container to maintain their viability. This process will help maintain a healthy and productive seed bank.
