Seed Saving: Harvesting, Drying and Storing for Next Season - Ep. 322
Seed Saving: Harvesting, Drying and Storing for Next Season - Ep. 322 Oct 13, 2026 00:43:10 Every fall somebody asks me if they can save the seeds from that amazing tomato or melon they just ate, and the answer is "maybe." Whether a saved seed grows into the plant you loved gets decided twice. The first time is months earlier, when the flower was pollinated, and the second is after harvest, when the seed either stays in the right conditions or doesn't. In this episode we're cov
Preserving Without Canning - Ep. 321
Preserving Without Canning - Ep. 321 Oct 6, 2026 00:42:06 Canning gets most of the attention, but for a lot of what comes out of the garden, it isn't the best way to put food up. In this episode, we're opening up the rest of the preserving toolbox: freezing, drying, fermenting, refrigerator pickles, and good old-fashioned cold storage. We'll talk about why skipping the blanch (or cutting it short) costs you flavor and color in the freezer, which vegetabl
Home Canning Myths Debunked - Ep. 320
Home Canning Myths Debunked - Ep. 320 Sep 29, 2026 00:34:31 A jar that seals is a jar that seals, and that's about all it tells you. In this episode, we're taking on four home canning myths that keep circulating in gardening groups, on food blogs, and in family recipe boxes: oven canning, open-kettle canning (and its cousin, flipping jars upside down), packing tomatoes and garlic in oil, and the idea that a salsa recipe can be tweaked however you like as l
End-of-Season Tomato Rescue: Ripening, Freezing, and Preserving - Ep. 319
End-of-Season Tomato Rescue: Ripening, Freezing, and Preserving - Ep. 319 Sep 22, 2026 00:30:40 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 show
Cover Crops in the Home Garden - Ep. 318
Cover Crops in the Home Garden - Ep. 318 Sep 15, 2026 00:36:22 Every empty bed in your garden is either growing something for you or growing weeds and losing topsoil. Cover crops are how you make sure it's the first one. In this episode, we get into why cover crops work in both in-ground beds and raised planters, which ones perform best when you sow them in fall, and which ones are worth a spot in your rotation come spring. We'll look at nitrogen-fixing legum
Fall-Planted vs. Spring-Planted Onions: Choosing the Right System for Your Garden - Ep. 317
Fall-Planted vs. Spring-Planted Onions: Choosing the Right System for Your Garden - Ep. 317 Sep 8, 2026 00:34:24 Onions are having a moment in the seed catalogs right now, and a lot of that buzz is about overwintering them, tucking small transplants into the bed in September, letting them sit through the cold, and pulling bigger, earlier bulbs the following June. It sounds like a clear win. But the biology underneath it is more particular than the marketing lets on, and the trade-offs are real. In this episo
Choosing a Garlic Variety Based on the Science - Ep. 316
Choosing a Garlic Variety Based on the Science - Ep. 316 Sep 1, 2026 00:38:10 It's the middle of summer, and I want you thinking about garlic. Not because it's time to plant, but because if you wait until it's time to plant, the good seed garlic may already be gone! In this episode, I'm breaking down the real difference between hardneck and softneck garlic: the cold-exposure requirement called vernalization that decides which type will bulb properly in your garden, how clov
How to Know When Winter Squash is Ready to Harvest (and How to Store Them) - Ep. 315
How to Know When Winter Squash is Ready to Harvest (and How to Store Them) - Ep. 315 Aug 25, 2026 00:26:26 Winter squash gives you almost no obvious warning before it's ready, and pulling it too early is one of the most common mistakes gardeners make. And that mistake costs you flavor, sugar content, and months of storage life. In this episode, we're breaking down exactly how to read maturity on butternut, acorn, spaghetti, delicata, and storage pumpkins: the rind test, the ground spot, and the specifi
Who's Eating My Garden? Identifying and Deterring Common Backyard Wildlife - Ep. 314
Who's Eating My Garden? Identifying and Deterring Common Backyard Wildlife - Ep. 314 Aug 18, 2026 00:30:14 Something has been eating your tomatoes, mowing your green beans down to nubs overnight, or turning your flower bed into a construction site, and you want to know who's responsible and what will make them stop. In this episode, we're working through the full lineup of backyard garden critters, starting with the animals most home gardeners deal with every season: squirrels, chipmunks, rabbits, deer
Organic, Conventional, or Homegrown: What the Research Really Shows About Nutrition - Ep. 313
Organic, Conventional, or Homegrown: What the Research Really Shows About Nutrition - Ep. 313 Aug 11, 2026 00:31:18 You've probably heard both sides of this argument: that organic and conventional produce are nutritionally identical, and that homegrown vegetables blow store-bought out of the water. Which one is true? In this episode, I dig through the peer-reviewed research on three separate questions: whether organic farming produces more nutritious food, whether soil health itself changes the nutrient content
Why I Trust University Extension - Ep. 312
Why I Trust University Extension - Ep. 312 Aug 4, 2026 00:35:34 If you've listened to this show for any length of time, you've heard me point to University Extension again and again as my go-to source. But I've never actually explained why. In this episode, we're pulling back the curtain on the Cooperative Extension System: where it came from, starting with farmers comparing notes in the early 1800s, through the Morrill Act's creation of land-grant universitie
The Science We Got Wrong: How Plant Research Rewrote the Rules for Gardening - Ep. 311
The Science We Got Wrong: How Plant Research Rewrote the Rules for Gardening - Ep. 311 Jul 28, 2026 00:41:18 For most of the last century, gardeners were taught to cultivate their soil after every rain to conserve moisture, to think of plant roots as lone competitors, and to treat "plant communication" as science fiction. All of that was built on the best evidence available at the time, and all of it has been revised, in some cases more than once, as better tools let researchers see what earlie
