Before tossing away old seed or ordering new seeds from your favorite seed catalog you should test the older seeds you have to save you a bit of time and money. Testing older seed germination rates can save you from wasting time, seed starting soil and supplies on seeds that may not sprout. A seed germination test is really simple and can be done by any home gardener with items you already have around the home. Do this seed viability test at home before planting your older seeds.
