It's too late for me to do any planting within my garden because everything is already blooming and new plants wouldn't ever pick up up. But I've gotten ahold of new seed.
I bundle mine in thesis coin envelopes and store them in an airtight box on the biggest floor of my house. Works for me - some of the more obscure variety may have to be cold stored - some may not store ably at all, and inevitability to be planted right away - but MOST seeds are fine if kept relatively cool and dry.
I maintain mine in jar with lid. Away from heat.
I also hold some in envelopes within a dark cool small file cabinet.
You can check to see if they are still good by putting a few on a drizzling paper towel, fold it, and next put it into a baggy. Put within a warm spot such as lying on your fridge, but not in the sun. Open it surrounded by a week to ten days to see if they have sprouted.
Answers: Keep seeds surrounded by a dark, cool place. It's base more upon proper storage than time. Seeds found in Egyptian tombs sprouted. Viable for 2,000 years. So within ya go.
