Have you ever compared a packet of conventional seeds and a packet of organic seeds and wondered what the difference truly is? My guest this week — to demystify what it means when seeds are organic — is Tom Stearns, a pioneer of growing and selling organic seeds.
Tom Stearns is the founder and owner of High Mowing Organic Seeds in northern Vermont, the country’s first organic seed company. I had the pleasure of meeting Tom in 2018 during filming for an episode of my public television show, Growing a Greener World®. Still today, High Mowing remains one of the few sources of organically grown seeds.

As we are at the onset of seed-ordering season, I thought it would be a good time to revisit my conversion with Tom. For more information on what we discussed, you can check out the show notes from the original airing.
To help you get more organized and take stock before buying seeds in anticipation of the 2021 growing season, I have prepared two free resources to share with you: a seed inventory chart that you can customize in Google Sheets, plus a seed longevity chart for your reference when you’re deciding which old seeds to hang onto and which can be disposed of.
You can download both charts as PDFs, or text SEEDGUIDES to 44222 to receive the free download links.
As you look ahead to seed starting in spring, know that my joegardener Online Gardening Academy™ Master Seed Starting course is relaunching at the end of January 2021. The course covers everything you need to know to start your own plants from seed. You can sign up to be notified when enrollment begins.
