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
Mulch Matchmaking: Choosing the Right Mulch for Your Vegetable Garden - Ep. 302
Mulch Matchmaking: Choosing the Right Mulch for Your Vegetable Garden - Ep. 302 May 26, 2026 00:50:33 Mulch is one of the highest-return investments you can make in your vegetable garden and yet most gardeners are using whatever happens to be available rather than whatever would actually work best for their situation. In this episode, we dig into the full lineup of organic mulches—straw, shredded leaves, wood chips, pine needles, grass clippings, and compost—as well as a shorter look at inorganic

Spring-Planted Bulbs and Summer Blooms: A Guide to Growing and Storing Dahlias, Gladiolus, and More - Ep. 301 May 19, 2026 00:51:56 A listener asked for a deep dive on dahlias and I’m delivering, from the ground up (pun intended). But we’re not stopping there. In this episode, I’m covering the full world of spring-planted bulbs: dahlias, gladiolus, cannas, calla lilies, and tuberous begonias. You’ll learn when and how to plant them, how to grow them for maximum blooms, how to cut them for the vase (because that’s half the fun)
Episode 300: The Questions You Keep Asking (and What the Research Actually Says)
Episode 300: The Questions You Keep Asking (and What the Research Actually Says) May 12, 2026 01:06:35 We made it to 300 episodes! And to celebrate, I’m doing something a little different. I went looking for the questions home gardeners are asking most, the ones showing up in Reddit threads, Facebook groups, university extension Q&A lines, master gardener helplines, and my own DMs and emails, over and over and over again. Then I went to the research: university extensions, peer-reviewed horticu
Topping Peppers: What does the science say, yay or nay? - Ep. 299
Topping Peppers: What does the science say, yay or nay? - Ep. 299 May 5, 2026 00:28:07 The subject of whether you should top your pepper plants can bring on a pretty strong debate among gardeners. That’s because this is one of those topics where the answer genuinely is: it depends. And I mean that in a very specific, evidence-based way that comes down to two things: your climate and your pepper type. I’ll be straight with you, I do not top my peppers. We are in a zone 6b in west cen
