Every spring, gardeners sow a packet of old seed, wait three weeks for nothing, and lose the best planting window.
Seed dies quietly, a packet can look perfect and be stone dead inside. I wrote this so you can find out, in ten minutes, before you commit soil and space to it.
Inside you’ll find the reliable paper-towel germination test (with a real percentage, not a guess), the quick float test and its honest limits, and a results-to-action table that turns your germination rate into exactly how to sow.
There’s also a reference for how long different seeds last, and how to store seed so it stays alive, since bad storage is usually why seed dies. Test first, plant with confidence.
