Just Grow Something | Evidence-Based Home Gardening

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!

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 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.

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 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.
