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

Mid-Season Fertilizing: How to Know What Your Vegetables Actually Need - Ep. 306 Jun 23, 2026 00:41:35 It’s June, your tomatoes are climbing, your corn is waist-high, and the internet is full of fertilizing advice—most of it missing the most important variable: timing. In this episode, we dig into what your vegetables need right now at mid-season, why nitrogen timing is the thing most gardeners get wrong, how fruiting crops and leafy crops have completely different needs, and when fertilizing can a
Early Blight Versus Late Blight in Tomatoes: Don't Get This One Wrong! - Ep. 305
Early Blight Versus Late Blight in Tomatoes: Don't Get This One Wrong! - Ep. 305 Jun 16, 2026 00:41:02 Every June, one of the most common questions that floods gardening groups, emails, and extension offices is some version of: “My tomato leaves are turning brown — do I have blight?” The confusion is completely understandable, because there are two diseases that get lumped under that word — and they are caused by completely different organisms, show up in different ways, and require completely diff
How to Manage Squash Vine Borer - Ep. 304
How to Manage Squash Vine Borer - Ep. 304 Jun 9, 2026 00:45:00 Every year, gardeners across the country watch their squash plants collapse overnight and have absolutely no idea why until it’s too late. The culprit is the squash vine borer, and it is one of the most misunderstood pests in the home garden. In this episode, Karin Velez breaks down the full life cycle of the squash vine borer, including regional timing differences that explain why gardeners in Fl
How to Identify and Manage Perennial Weeds (Without the Viral Sprays) - Ep. 303
How to Identify and Manage Perennial Weeds (Without the Viral Sprays) - Ep. 303 Jun 2, 2026 00:52:42 Perennial weeds are in a different category than annuals. They don’t just re-seed, they regrow from the ground up, season after season, from root systems that can run three feet deep or spread fifteen feet sideways underground. In this episode, we’re tackling them systematically. First, a regional tour of the most aggressive perennial weeds in the U.S. - what they look like, how they spread, and w
