How to Harvest and Store Heirloom Tomato Seeds for Reliable Germination

User Question: I'm trying to save tomato seeds harvested directly from the fruit. How can I ensure they stay viable after storage for healthy new plants? It's a rare heirloom variety from an old-timer—unknown name, but fruits hit 1kg with abundant flesh and few seeds! Specific tips (newspaper, quick drying, light)? Planning to grow them next spring. Thanks!

Hi Grandma Catou,
Harvesting tomato seeds is simple and foolproof when done right. As experienced gardeners who've preserved countless heirloom varieties, here's our trusted method:
Fully ripen the fruit on the vine.
Gently crush it and spread seeds on a thick layer of paper towel.
Let them dry fully in a warm, airy spot away from direct sun.
Come spring, lay the towel flat on moist potting soil in a tray, cover lightly, and keep damp. Germination is guaranteed.
You'll yield far more than three viable seeds for your giants!
