How a seed germinates
WebAdd 10 seeds and close up the bag. Store it upside down at room temperature until the seed germinates. Count the number of germinated seeds and multiply by 10 to get the germination rate. So if 7 of the 10 seeds germinated, you have a 70% germination rate. You do not need to use 10 seeds, but if you do, the math is a bit easier.
