    Greenhouse Tradeoffs: Heat, Humidity, Pests, and Practicality - Ep. 293

    Get my free guide to choosing which protected gardening structure you should choose - https://justgrowsomethingpodcast.com/greenhouse Protected growing structures like greenhouses can be game-changers - earlier harvests, fewer rain-splashed diseases, better crop quality, and more reliable timing. But they also create a new microclimate with new rules: overheating, humidity spikes, irrigation demands, shifting pest pressure, and sometimes pollination problems. Today on Just Grow Something, we break down what problems protected culture solves, what it tends to make harder, and how to predict those tradeoffs before you invest. You’ll learn the core principals of tunnels and greenhouses, like temperature, humidity, airflow, and water, plus what changes when you grow in containers, raised beds, or in-ground under cover.

    How to Pick the Right Greenhouse, Tunnel, or Cold Frame - Ep. 292

    Download my Protected Growing Quick Guide to help you make the decision on what type of structure would work best in your garden: https://justgrowsomethingpodcast.com/greenhouse Thinking about a greenhouse but not sure if you really need one? There are some beautiful and expensive options out there, but greenhouses aren’t the only option for extending the season your garden. Today on Just Grow Something, we map out the full spectrum of protected growing structures for home gardeners: from cold frames and covered shelving to low tunnels, caterpillar tunnels, hoop houses/high tunnels, and home greenhouses. You’ll learn what each option is best for, how to match a structure to your goals, space, budget, and maintenance tolerance, and which “hidden factors” make or break success, like site selection, orientation, wind exposure, and snow load. By the end, you’ll have a clear decision framework so you can choose a protected structure that fits your garden and your life, not just your Pinterest board.

    Hardening Off Homegrown AND Storebought Seedlings - Ep. 291

    Hardening off is the difference between sturdy transplants that take off fast and seedlings that stall, scorch, or collapse after planting. Today on Just Grow Something, you’ll learn what to do indoors before hardening off, a simple step-by-step hardening-off schedule (including temperature guidelines, shade vs. sun, wind protection, and watering adjustments), and what to watch for when you transplant. We’ll also cover the “mystery variable” of purchased seedlings and how to treat garden-center starts if you’re not sure they’ve been acclimated. Then, in the second half, we’ll talk about how the process changes when you’re using a greenhouse, cold frame, or high tunnel and why protected structures can help without eliminating the need to transition plants carefully.

    How to Time Seed Starting for Your Garden: Start Dates That Make Sense - Ep. 290

    Timing your seed starting shouldn't be hard. There are plenty of calendars to follow, right? Until following a calendar means you start too early, run out of space, and end up babysitting leggy, root-bound seedlings for weeks. Or you start too late and miss the planting window you planned for. So, today on Just Grow Something, we're connecting the dots between frost dates, planting calendars, and harvest windows to build a seed-starting schedule that fits your garden and your climate. You’ll learn which crops are best started indoors vs direct sown, which plant families need a long “grow-on” period, how to avoid common timing traps, and a step-by-step way to pick seed-starting dates based on your planned transplant date or your desired harvest window. Let's dig in! If you need some additional help with starting your seeds indoors, it’s not too late in the season to take my Seed to Sprout course. In about 90 minutes you’ll know everything you need to know about getting your seeds started in the proper containers, with the right balance of lighting, water, and air flow, and how to get them transitioned to the garden with very little shock or damage. https://www.justgrowsomething.com/indoor-seed-starting University of Missouri Extension — Starting Plants Indoors From Seeds: https://extension.missouri.edu/publications/g6570 Illinois Extension (Good Growing) — When should I start my seeds?: https://extension.illinois.edu/blogs/good-growing/2023-02-10-when-should-i-start-my-seeds Just Grow Something: https://justgrowsomething.com Gardening Courses: https://justgrowsomething.com/courses Just Grow Something Merch and Downloads: https://justgrowsomething.com/shop Just Grow Something Gardening Friends Facebook Group: https://www.facebook.com/share/g/18YgHveF5P/ Check out how you can become a patron on Patreon: https://www.patreon.com/JustGrowSomething Bonus content for supporters of the Podcast: https://buymeacoffee.com/justgrowsomething Amazon storefront: https://www.amazon.com/shop/justgrowsomething

    Spring Garden Bed Preparation - Ep. 289

    If you want an easier garden season, February is the time to set the foundation. Two steps do most of the heavy lifting: getting a soil test and prepping beds without damaging soil structure. Done well, these tasks reduce fertilizer guesswork and improve root growth. You can do a lot right now that sets you up for success without rushing into two classic mistakes: 1. throwing amendments at the garden without knowing what the soil actually needs, and 2. working soil while it’s still too wet, which can damage structure for the long haul. So, today on Just Grow Something, I’m walking you through what a soil test can (and can’t) tell you, exactly how to collect a sample that’s representative of your whole garden, the key parts of a soil report that matter most for vegetables, and bed prep steps you can do now that improve soil instead of compacting it.

    Indoor Seedling Troubleshooting - Ep. 288

    Today is a clinic episode, a Seedling Troubleshooting Clinic to be exact, because if you’re starting seeds indoors, something is eventually going to look weird. A tray that was perfect yesterday is suddenly leaning. Something looks fuzzy on the soil surface. Or a seedling that seemed fine just flops over. The good news is most seedling problems come from a small handful of causes, causes that we can actually control - light, temperature, water, airflow, or sanitation. And once you know what you’re looking at, you can usually fix it quickly or at least stop it from spreading to the rest of your tray. So, I’m going to give you a simple diagnostic checklist and then we’ll walk through the most common seedling symptoms and what to do about each one. Let's dig in!

    Onions vs Shallots in the Kitchen and the Garden - Ep. 287

    Onions and shallots are closely related, they can be used in similar ways, and they look similar at the store, but they behave differently in both the kitchen and the garden. So, today on Just Grow Something we’re doing a side-by-side comparison of these alliums. We’ll cover how they differ in taste and cooking uses, how they differ in growth habit, how to grow each one, and finally, how to adapt for hot climates and short-season climates, because those two extremes can make or break your allium crop. Let’s dig in.

    Five Spring Crops to Plant Earlier Than You Think - Ep. 286

    If you’ve ever planted a big patch of arugula at the same time you planted the rest of the spring garden, only to watch it shoot up a flower stalk a few weeks later, you’ve already met this week’s topic: heat-sensitive crops. Heat-sensitive doesn’t always mean a plant can’t survive warm weather. It usually means warm temperatures and lengthening days change the plant’s priorities. Instead of producing the leaves, heads, or tubers we want to harvest, the plant pivots toward flowering and seed production or it keeps growing, but quality drops. So, today on Just Grow Something we’re talking about the five crops you should plant earlier than you think to avoid this change. And I’m also including an herb that can bolt as fast as you blink. Let’s dig in.
