Storage and germination
To find out how the seeds have coped during storage, you can test the germination rate before sowing. Spread 20, 50 or 100 seeds on a damp paper towel. Fold it lightly to enclose the seeds and put it in a plastic bag. The seeds germinate quickly if left at room temperature. Count the ones that have germinated within the normal germination time (see table) and calculate an approximate percentage. For example, 40 germinated seeds out of 50 = 80 % germination. One usually does not sow seeds with lower rate than 50 %.
