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
The Mid-Season Soil Check - Ep. 310
The Mid-Season Soil Check - Ep. 310 Jul 21, 2026 00:39:40 Your garden is at its busiest in July, and so is the wear and tear on your soil. In this episode we get past the fertilizer conversation and into whether your soil is still functioning at all — how traffic, pounding rain, heat, and heavy-feeding crops degrade soil mid-season, the physical, chemical, and biological warning signs to look for right now, and tests you can run this week to sort the pro
Battling Blossom End Rot the Right Way - Ep. 309
Battling Blossom End Rot the Right Way - Ep. 309 Jul 14, 2026 00:24:35 If you've grown tomatoes or peppers for more than one season, you more than likely know the feeling been waiting that first tomato to ripen, finally see it’s blushing red, and you flip it over to find a sunken, leathery patch covering half the bottom of the fruit. And if you went looking for answers, you probably found three of them repeated everywhere you turned: sprinkle in some crushed eggshell
Heat Stress vs Drought Stress in the Vegetable Garden - Ep. 308
Heat Stress vs Drought Stress in the Vegetable Garden - Ep. 308 Jul 7, 2026 00:31:04 It's two o'clock on a July afternoon. You walk out to check the garden, and your squash leaves are drooping so low they're nearly touching the mulch. Your tomato plants look like they've given up on the whole season. If your first thought, every single time, is “I need to water right now,” hold on a second before you grab that hose. Because that dramatic afternoon collapse you're looking at likely
How to Time Your Fall Brassicas - Ep. 307
How to Time Your Fall Brassicas - Ep. 307 Jun 30, 2026 00:25:53 Fall gardening doesn't start in September. For the crops that take a long time to produce, your broccoli, your cauliflower, your cabbage, your Brussels sprouts, it starts right now in late June and early July. And if you've never had a productive fall brassica bed, it's almost certainly because you started too late and it took me a lot of years to master this. This episode is about fall gardening
