They say to preserve them properly, seeds should be kept in a cool, dark place in a sealed, dry container. Yet the circumstances under which seeds in a natural environment store themselves (so to speak) seem so far from ideal, that it’s a wonder plants manage to reproduce at all. But any gardener knows that plants not only manage to reproduce, they excel at it. Who hasn’t thrown a giant squash into the compost heap in the fall only to see some mystery squash growing there the next summer?
Saving seed is fairly simple to do, but the results from planting those seeds can be very mixed; without a basis of understanding of seed quality, people can be disappointed and confused as to why they got the results they did. Both the home gardener and the seed company must understand seed quality to be successful in their respective endeavors.
