Planting by the Moon - Ep. 270 Oct 07, 2025

Show notes

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 have been asked about gardening by the moon’s phases so many times, so today on Just Grow Something we’re digging into the science—why we think the lunar cycle can affect our garden, what’s been tested, and what hasn’t. And at the end you can decide whether you want to modify your planting calendar next season to include the phases of the moon. Let’s dig in!

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.

Is your summer tomato crop struggling with strange spots, brown mushy bottoms, or mysteriously vanishing leaves? You’re not alone! Mid-season brings a whole host of challenges for tomato gardeners, but with a little know-how, you can keep your plants thriving through to fall.

I share a trick for spotting hornworms at night, how often to feed tomatoes in pots vs. beds, the signs and treatment of tomato leaf diseases, and the most effective organic control methods (from copper sprays to simple sanitation practices).
