Planting by the Moon in East Tennessee

Long before seed packets, apps, or planting charts, folks around here watched the sky.

If you grew up hearing an old farmer say, “Plant by the moon,” they weren’t being poetic — they were passing down hard-earned knowledge. The phases of the moon affect moisture in the soil and how plants put on growth. Pair that with East Tennessee’s frost dates, and you’ve got a tried-and-true way to raise a good garden.

It’s not magic. It’s timing.

How Farmers Have Used the Moon for Generations

Here’s the simple, old-school breakdown — what to plant and when, based on the moon’s cycle.

New Moon to First Quarter (Waxing Moon)

Light’s increasing. Things want to grow upward.

Plant above-ground crops:

• Lettuce, kale, spinach

• Tomatoes, peppers, beans

• Corn, cucumbers, squash

Why: As the moon grows brighter, soil moisture increases and plants push energy into leaves and fruit.

First Quarter

Good growing days.

Plant or transplant:

• Fast-growing vegetables

• Continue above-ground crops

• Transplant seedlings started indoors

• This is when plants take hold well and get established.

Full Moon

Plant or transplant:

• Root crops: carrots, beets, potatoes

• Transplant tomatoes and peppers

Why: Soil moisture is at its highest, and plants are at their strongest.

Full Moon to Last Quarter (Waning Moon)

Best for root crops:

• Onions, turnips, radishes

• Carrots, potatoes

• Avoid planting leafy crops during this phase.

Why: With less moonlight, plants slow their top growth and build stronger roots.

Last Quarter

Work, don’t plant.

Focus on:

• Weeding and pruning

• Soil prep

• Harvesting

• Growth slows during this phase, so it’s best to tend what you’ve already planted rather than start something new.

Don’t Forget the Frost Dates

Around here, the moon works best when you respect the weather.

East Tennessee (Zones 7a / 7b):

• Last spring frost: April 10–15

• First fall frost: October 10–20

Use frost dates to set your planting window. The moon just helps you fine-tune the timing.

A McKinney Farm Tip

You don’t need fancy apps or paid tools. Farmers did this for generations with nothing more than the sky, the soil, and their hands. Know your frost dates. Watch the moon. Stay consistent. The rest comes down to good dirt, sunlight, and showing up every day.
