Container Gardening 101 - Ep. 297
2026/04/21
No yard? No tiller? No problem. If you've got a patio, a porch, a balcony, or even a sunny driveway, you can grow a real, productive vegetable garden in containers.
Today on Just Grow Something, we walk through the essentials of container gardening from the ground up: how to evaluate whether a crop is a good candidate for a pot, how to pick the right container size based on root system and mature plant size, what kind of soil to use (and what NOT to use), how to feed your plants organically, and the special considerations that make container growing a little different than growing in the ground — things like light, drainage, airflow, watering, and trellising.
Whether you're a total beginner or someone adding containers to an existing garden, you'll walk away knowing how to get your best start. Let’s dig in!

Succession Planting 101: How to Keep Your Garden Producing from Spring Through Frost - Ep. 296
2026/04/14
Empty beds mean missed harvests. But with the right plan, they're completely avoidable. Today on Just Grow Something I'm walking you through succession planting and relay planting, the strategies that keep your garden productive not just across space, but across time.
Whether you're dealing with a four-month growing season or gardening in year-round heat, there's a succession approach that works for your climate. I break down the three types of succession crops, explain how to build a planting calendar that eliminates gaps, and get into relay planting, where you plant your next crop into your current one before it's even finished so there's never a moment of wasted ground.
I've also included a full dos and don'ts list, because a few key mistakes can turn a great succession plan into a depleted bed and a missed season.
In this episode:
The four types of succession planting and when to use each one
Rapid, mid-range, and long-season crops and how to succession plant each category
Why cucumbers, zucchini, and squash practically require succession planting (and exactly how I do it)
Relay planting: how it works, why it's different from interplanting, and some of my favorite pairs
Succession strategies by climate: short season, mid-range, and long hot season
A full dos and don'ts list, including the disease rotation mistake most gardeners don't see coming
This episode pairs with last week's episode on interplanting — together, they give you a complete system for filling every bed, every season.

Interplanting Done Right: The High, Low, Fast, Slow Method for Bigger Harvests - Ep. 295
2026/04/07
What if you could get more food from the exact same garden space, without expanding a single bed? That's the promise of interplanting, and today on Just Grow Something I break down exactly how to do it right.
Building on the "high, low, fast, slow" mantra I use in my own garden and teach in my Plan Like a Pro course, I walk you through the framework that makes interplanting work and the common mistakes that turn it into overcrowding. I cover what to consider before you ever put two plants together (mature size, water needs, nutrient timing, and allelopathy), then get practical with six beginner-friendly pairings that are low-risk and high-reward, plus advanced combinations and experiments for experienced gardeners ready to push further.
I've also put together a clear list of dos and don'ts to keep on hand when you're planning your beds.
In this episode:
What interplanting, intercropping, and companion planting actually mean
The "high, low, fast, slow" framework and how to apply it to any bed
What to know about your plants before pairing them (and what can go wrong if you don't)
Six beginner pairings: tomatoes + basil, lettuce + tomatoes, radishes + carrots, peas + spinach, garlic + peppers, cucumbers + lettuce
Advanced ideas: trap cropping, stacked seasonal beds, the Three Sisters and beyond
A full dos and don'ts list for interplanting success
Let's dig in!

Your Greenhouse Operating Manual - Ep. 294
2026/03/31
Get my greenhouse selection guide to help you choose which protected growing structure is right for you: https://justgrowsomethingpodcast.com/greenhouse
A protected growing structure isn’t “set it and forget it” but a microclimate you manage. In this final episode of our greenhouse mini-series, you’ll get a practical operating manual for cold frames, low tunnels, caterpillar tunnels, high tunnels, and home greenhouses.
We’ll cover ventilation, heating and cooling strategies, watering and irrigation basics, container vs raised-bed vs in-ground considerations, pollination management, and an evidence-based approach to pest and disease control.
We’ll also tackle a topic many gardeners miss until something goes wrong: soil health under cover, including salt buildup, nutrient imbalances, and why protected soils often need a different fertility strategy than open-field beds.
Let’s dig in!

Greenhouse Tradeoffs: Heat, Humidity, Pests, and Practicality - Ep. 293
2026/03/24
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
2026/03/17
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
2026/03/10
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.
Let’s dig in!

How to Time Seed Starting for Your Garden: Start Dates That Make Sense - Ep. 290
2026/03/03
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

Spring Garden Bed Preparation - Ep. 289
2026/02/24
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
2026/02/17
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.

Onions vs Shallots in the Kitchen and the Garden - Ep. 287
2026/02/10
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
2026/02/03
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.

Creating Your Garden Calendar - Ep. 285
2026/01/27
My Plan Like A Pro Course is Open for Registration: https://justgrowsomethingpodcast.com/pro
If you’ve ever gone into a Facebook gardening group and asked, “When am I supposed to plant this?” and then gotten ten different answers, you are not alone.
And if you’ve ever started seeds too early, ended up with giant leggy plants taking over your house, and then still got hit with a late cold snap? Also not alone.
Today on Just Grow Something we’re going to make garden timing feel simple, flexible, and predictable.
I’m going to show you how to build a planting calendar using frost dates as your starting point, then layering in:
• cool-season versus warm-season timing,
• how many weeks to start seeds indoors,
• a buffer for weather variability,
• and how to plan your fall garden by counting backward from your first frost.
This is one of those “once you understand it, you can reuse it forever” skills.
Let's dig in.

The Low Maintenance Garden Plan - Ep. 284
2026/01/20
If you’ve ever planned a garden that looked amazing on paper and then halfway through summer you thought, “I do not have the time for this,” this episode is for you.
Because a garden can be beautiful, productive, and fun and still be too much if the plan doesn’t match your real life.
Today on Just Grow Something we’re building a low-maintenance garden plan. Not by choosing “easy plants,” but by designing your garden around the things that actually determine how much work it takes: location, layout, watering, weed control, and disease pressure and how that fits into the rest of your actual life.
Low-maintenance does not mean low-yield. It means fewer chores that pile up, fewer “emergency problems,” and a garden that still functions when your life gets busy.
As we go, I’ll give you simple action steps you can do in January to set this up. Because the easiest gardening season is the one you design on purpose.
Let's dig in.

How to Keep the Garden Producing All Season - Ep. 283
2026/01/13
If you’ve ever had that one magical week where the garden is giving you exactly what you want - some lettuce, a few carrots, a handful of beans, a couple tomatoes - and then two weeks later you’re drowning in zucchini while everything else is kind of between harvests ...
Today we’re fixing that.
Because the goal for a lot of home gardeners isn’t “the biggest harvest possible on one weekend.” The goal is steady, usable harvests week after week so you’re actually eating from the garden regularly, without a sudden produce avalanche.
So today on Just Grow Something, I’m going to teach you a planning method that revolves around harvest windows.
Instead of only asking, “When do I plant this?” we’re going to ask:
“When do I want to be harvesting this, and do I want it over and over again?”
I’ll walk you through a simple framework and give you a few practical “rules of thumb” for how often certain crops can be re-planted or staggered to keep the harvest going.
Let's dig in!
