In my last blog I mentioned that conditions for proper seed storage are basically the opposite of what seeds need to germinate. To grow they need moisture, warmth, and light; for storage they need cool temperatures, dry atmosphere, and darkness. Most seeds will last for about three years if stored properly—often they last much longer.
What should you do if you have some seeds that have been lying around for several years and you are not sure if they will germinate? There is a simple way to test a seed’s viability before you prep your seed trays and waste your seed sowing medium on something that has little life left in it.
Moisten a few paper towels with water. Place a dozen or so seeds spaced apart on the towel. Then either hold on to one of the edges of the paper towel and roll it up into a spiral, or place a few damp paper towels on top to create what looks like a seed-germination sandwich. Either way the seeds need to be encased on both sides by damp paper towels. read more »
