A Handy Chart on Seed Longevity
In one of my latest blog posts, I talked about how to assess your seeds to find out whether they were duds before planting time. Writing about that topic piqued my interest in finding out more, so I did some research and found a great chart that garden guru Margaret Roach posted on her always informative Web site. Here is the link: http://awaytogarden.com/estimating-viability-how-long-do-seeds-last.
Roach compiled the chart based on seed viability estimates from four sources: extension services in Iowa and Vermont, Johnny’s Selected Seeds catalog, and the Fedco seed catalog. She notes in her post that it’s no wonder we all get confused about how long seeds last. Depending on the source, for example, tomato seeds can last anywhere from four to ten years. Her post, and the chart, are definitely worth a look.
