End-of-Season Tomato Rescue: Ripening, Freezing, and Preserving - Ep. 319

September 22, 2026·30 min
Episode Description from the Publisher

Frost is on the way, and the vines are still loaded with green tomatoes. In this episode, we sort out which green tomatoes will finish ripening on your counter (the mature greens and the blushers) and which ones belong in the skillet, the freezer, or a tested relish recipe. You'll learn what cold does to a tomato, why a stretch of chilly weather can cost you ripening ability before frost ever shows up, and four ways to ripen fruit indoors, including how to stage a harvest for a steady supply into November. Then we dig into the canning rule that catches a lot of gardeners off guard. National home-canning guidance says not to can tomatoes from dead or frost-killed vines, and we look at why, what the research does and doesn't show, and what to do with those tomatoes instead. Grab a notebook and let’s dig in!
