Got some old seeds around and not sure whether they’re viable? Me too! I kept ignoring these pumpkin seeds in their mason jar for roughly 4 years and first tested them about 2 weeks ago by soaking then for a few hours. They all floated, which supposedly means they’re not viable. But I wasn’t totally convinced and figured I’d try another method: the paper towel test!
The idea here is that you moisten two paper towels and lay out the seeds between them. Seal these in a Ziploc and place somewhere warm but not in direct sunlight. I left them alone like this for about a week, and came back to surprising results!
Success! I sowed these wee plants this morning and we’re now sitting under a tropical storm warning with rain starting 2 hours before it was supposed to. They’re off to a marvelous start!
