How do you separate good seeds from bad seeds?

Why do old seeds not germinate?

By keeping seeds cool — at 40 degrees Fahrenheit or lower — and dry — 8 percent relative humidity or lower — their drive to germinate can be repressed. As seeds age, the embryos still wither, decreasing the number of viable seeds, or rate of germination.

Why do seeds float in water?

Seeds may float because they lack viable embryos or nutrient stores, making them less dense than “good” seeds that sink in water. Or, they may float because they have air pockets inside, which don’t always affect seed vigor or viability. The only sure way to test germination is to use the coffee filter method.

Are seeds that float viable?

One method to check for seed viability is the water test. Take the seeds and place them in a container of water. Let the seeds sit for 15 minutes. If the seeds sink, they are still viable; if they float, discard, because they probably will not sprout.
