Old seed? Viability test is simple way to see if it's still good to sow

Anyone who has grown his or her own veggies for a few years will have wound up with at least one small box of all the leftover seed that wasn't sown in the past.

Seed is usually good for a year after it's sold, but after two years, different crops show varying seed viability. Some seed can last up to five years, or more, if stored properly. But other crops die out in just a year, especially if it's kept in warm, humid conditions.

This simple seed viability test featured in Marshall Hinsley's article for Dallas Culture Map shows an age-old way to see if you're still able to get some life out of your old seed or if you need to get some new packets.
