If you’ve ever stared at a seed catalog in January and thought, “I want all of it,” and then somehow ended up with a garden that felt chaotic by mid-summer, today’s episode is for you.

Because most “garden planning” advice starts with the fun part—varieties, colors, wish lists—and then we wonder why the plan falls apart when real life shows up.

So today on Just Grow Something, we’re going to flip the order.

I’m going to give you four ...

We’ve reached the end of another gardening year. Maybe your garden was spectacular. Maybe it was just so-so. Maybe it was an absolute disaster in certain beds and you’re still a little salty about the squash vine borers.

However it went, this is a powerful moment in the gardening calendar.

Today we’re going to slow down and talk about taking time to reflect on the past season, reset your expectations, and reimagine what you want from...

Seed catalog season is fun, but it can also be overwhelming. If you’ve ever ordered way more seed than you can possibly plant, chosen a variety that just did not perform in your climate, or gotten confused by all the codes, abbreviations, and marketing language this episode is for you.

Today on Just Grow Something we’re going to talk about how to read a seed catalog.

We’ll cover:

1. Why seed catalogs are tools, not just wish books

2. T...

Winter sowing is a seed-starting method that sounds a little bit wild the first time you hear it but makes sense if you think about it from a horticultural standpoint. Basically you are sowing seeds in recycled containers like milk jugs and placing them outside in the winter as a very hands-off way of starting your spring garden.

If you’ve ever:

• Run out of space under grow lights

• Been frustrated by leggy indoor seedlings

• Or just ...

When the garden beds are frozen, the days are short, and you’re staring at bags of store-bought salad mix, it can feel like fresh homegrown food is a long way off. But it doesn’t have to be.

Today on Just Grow Something we’re talking about growing herbs and leafy greens indoors in winter—on a windowsill, under a simple grow light, or with one of those countertop indoor garden systems

If you’ve ever thought:

• “I’d love fresh basil in ...

Today we’re talking about one of my least favorite but probably most important fall garden rituals: the great garden clean-up. This is the part of the year where we get to close one chapter of the garden season and start quietly writing the next chapter.

Now that most of the chaos of the garden is done, it's time to be putting things in order, protecting the soil, and setting yourself up for success next spring.

So, today on Just...

The frost has settled, most of the garden has gone to sleep, and now we’re turning our attention to what’s left — the fruits (and roots) of our labor.

I’m talking about how to store and preserve that late-season harvest, so all your hard work continues to pay off well into winter.

Today on Just Grow Something We’ll look at how long certain crops can remain in the garden, essentially in storage mode before you truly have to bring them...

If your forecast is flirting with frost and you still have all those lovely greens and root veggies out there, don’t panic, prepare.

Today on Just Grow Something we’re talking row cover and low tunnels: what to buy, how to set up fast, how to vent so you don’t cook your greens, and exactly which fabrics and plastics can squeeze out one more month of salads, herbs, and even late summer crops like beans or peas.

We’ll talk about using ...

Whether you live in a climate that allows for a veery long growing season or you’re like me and need to cram as much growing into a shorter season as possible, cloning is a shortcut to making the most of our best plants. In some cases it even makes sense to overwinter some of those plants so next season starts off weeks ahead of schedule.

So, today on Just Grow Something, we’re talking about the importance of cloning plants as a str...

Now is the time to be getting our garlic, shallots and even onions planted in some places. If you can give me one good hour in the garden this month, you can set yourself up for big flavor next summer.

Fallen leaves in the garden will blanket the soil, slow weeds, and shelter a whole mini-wildlife community. Many native butterflies, moths, beetles, and even some queen bumble bees ride out winter tucked into leaf litter and hollow stems. When we keep some of that litter in place, we’re giving next spring’s pollinators a head start.

That's the idea behind the National Wildlife Federation "Leave the Leaves" campaign. . ...

As I record this, tonight will be a full moon. In fact, it’s the Harvest Supermoon here in the northern hemisphere. And it’s very possible that your online gardening group is absolutely abuzz with advice that tomatoes grow better if you plant them in the days leading up to the full moon and your beets grow more voluptuous if you plant them after the full moon.

But does gardening by the moon actually change anything in your garden? I...

All this month we've been talking about creating new raised beds, what materials to use, and how to fill them. So, I thought it would be fitting to have on an expert on the subject.

If you are considering adding your first raised bed or yourfiftieth to your garden for next season, now is the time to be doing it. A new raised planter is going to have to be filled and that material is going to have to break down a bit before it can be planted in order to make the nutrients available to your plants. This is NOT something we want to put together at the last minute in the spring just before we start planting.

It's late August, the time of year when the garden can be just as likely to flourish as it is to fizzle out. I know all too well the rollercoaster of emotions we gardeners feel at this point in the season: you're hot, tired, maybe a little bit over it, and those early-season mistakes are showing their faces. But don’t give up!
