Seed viability times

The length of time that seeds can be stored is quite variable: for example, parsnip seeds are best fresh but peans and beans can keep for around 5 years.

Seed Viability Chart

Temperate Climate Permaculture's chart of seed viability times for the most common seeds used in gardens and farms

View online: http://tcpermaculture.com/site//06/14/how-long-will-seeds-last-stay-viable/

Ever wondered how long you can save your seeds and have them still be viable? We've created this chart to help you determine the longevity of your seeds.

Proper seed storage conditions are cool and dark. The moisture content within the seed greatly affects germination rates. Seeds should be stored in their original packaging in a cool (below 50 degrees Fahrenheit), dark place where their moisture content will stay relatively stable. Here at High Mowing we keep our seed cooler at around 45 degrees Fahrenheit with less than 40% humidity.
