Our Guarantee on Seed Viability
Every type of seed we sell has had a germination test done at the start of the seed selling season. Every variety of seeds has a acceptable range of germination in a certain timeframe to be considered good and healthy seed. For Example to have what is considered good germination for beans is above 75% in 7 days. If it takes longer then that to achieve 75% the seed is still technically viable but most likely will not do well as it is very weak seed. For beans we actually want 85% or higher in 7 days to be considered acceptable for selling.
To test germination we count out a test plot of seeds usually 50 or 100 to get a good percentage and then place on paper towel in a dish and keep moist. Most seeds like some heat to germinate so any families of seeds that do we place on a heat mat to help imitate warm soil. It is important not to let your paper towel dry out. Once you have reached the optimal number of days for germination count the number of seeds that have started to grow and calculate the percentage out of 100%. For example if 46 seeds germinated out of a test plot of 50 then that would be 92% viability.
