Planting by the Signs: How the Almanac Zodiac Man Works in the Garden
How planting by the signs works: the almanac Zodiac Man, fruitful and barren signs, light and dark of the moon, fall planting and what the research says.
In much of Appalachia and the rural South, a gardener who asks “where are the signs?” is not asking about the weather. She is asking which part of the body the moon is in today, according to the almanac on the kitchen wall. This guide explains how planting by the signs works, how to read the Zodiac Man, and how to use the method this fall. It does not claim that the moon will double your harvest; the evidence for that is thin, and we say so.

Planting by the signs is a folk gardening method, strongest in Appalachia and the Ozarks, that times farm work by the zodiac sign the moon is passing through and by the moon's phase. Almanacs show the signs as the Zodiac Man, a figure whose body parts stand for the twelve signs, from Aries at the head to Pisces at the feet. Water signs (Cancer, Scorpio, Pisces) count as the most fruitful for sowing, fire and air signs such as Leo and Gemini as barren and better for weeding and clearing. Crops that bear above ground go in while the moon waxes, root crops while it wanes. Controlled studies have not shown a reliable yield effect, so it works best as a rhythm for your garden year, not a guarantee.
The Foxfire Book (1972) documented planting by the signs as a living practice in the southern Appalachians.

Quick answer
Planting by the signs is a folk gardening method, strongest in Appalachia and the Ozarks, that times farm work by the zodiac sign the moon is passing through and by the moon's phase. Almanacs show the signs as the “Zodiac Man”, a figure whose body parts stand for the twelve signs, from Aries at the head to Pisces at the feet. Water signs (Cancer, Scorpio, Pisces) count as the most fruitful for sowing, fire and air signs such as Leo and Gemini as barren and better for weeding and clearing. Crops that bear above ground go in while the moon waxes, root crops while it wanes. Controlled studies have not shown a reliable yield effect, so it works best as a rhythm for your garden year, not a guarantee.
What planting by the signs means
Planting by the signs combines two old ideas. The first is that the moon's phase matters: what you plant in the “light of the moon” grows up, what you plant in the “dark of the moon” grows down. The second is that the moon's position in the zodiac matters too. As the moon circles the sky once in about 27 days, it spends roughly two to two and a half days in each of the twelve signs, and each sign is said to favor or hinder certain kinds of work.
The method came to North America with European settlers, many of them English, Scots-Irish and German, and it survived longest where almanacs were one of the few printed books in the house. In the southern mountains it became part of everyday life. The Foxfire project, which recorded mountain traditions in Rabun County, Georgia, from the late 1960s on, devoted a whole chapter of its first book to it in 1972, and older gardeners still speak of the signs “being in the feet” or “in the bowels” as naturally as others speak of the frost date.

The Zodiac Man: reading the body in the almanac
The heart of the method is a woodcut that has been printed in almanacs since the Middle Ages: the “Man of Signs”, also called the Zodiac Man or anatomical man. A naked human figure stands in the center, surrounded by the twelve zodiac symbols, with lines pointing from each symbol to a part of the body. Medieval physicians used the same figure to decide when to let blood; American almanacs kept it long after doctors had stopped.
The almanac then lists, for every day of the month, which sign the moon is in, often as a body part rather than a symbol. That is why country gardeners say “the signs are in the knees” instead of “the moon is in Capricorn”.
The Zodiac Man at a glance
| Sign | Body part | Element | Traditional garden reading |
|---|---|---|---|
| Aries | Head | Fire | Barren; clear, weed, cultivate |
| Taurus | Neck | Earth | Productive; root crops, potatoes, leafy greens |
| Gemini | Arms | Air | Barren; weed, till, destroy pests |
| Cancer | Breast | Water | Most fruitful; sow and transplant |
| Leo | Heart | Fire | Most barren; kill weeds, cut brush |
| Virgo | Bowels | Earth | Barren for crops; some sow flowers |
| Libra | Reins (kidneys) | Air | Semi-fruitful; flowers, vines, hay |
| Scorpio | Secrets (loins) | Water | Very fruitful; sow, graft, plant garlic |
| Sagittarius | Thighs | Fire | Barren; harvest, clear, store |
| Capricorn | Knees | Earth | Productive; roots, bulbs, fence posts |
| Aquarius | Legs | Air | Barren; weed, cultivate |
| Pisces | Feet | Water | Very fruitful; sow, transplant |
Traditions differ in the details. Some almanacs rank Taurus and Capricorn as fruitful, others as merely productive; some gardeners plant flowers in Virgo, others avoid it entirely. The pattern that nearly everyone agrees on is simple: water signs for sowing, fire and air signs for clearing.
Fruitful and barren signs
The logic behind fruitful and barren signs is elemental. Water signs are moist and receptive, so seed is said to “take”. Fire signs are hot and dry, so seed is said to rot or come up spindly, while weeds cut in those days are said not to return. Earth signs are solid and hold roots; air signs are restless and suit work that moves soil and breaks things up.
In practice this turns the month into a small work schedule. When the signs are in the feet or the breast, you sow. When they are in the heart or the arms, you hoe, pull, cut and burn brush. When they are in the knees, you set posts and plant potatoes. Nothing in the method says the barren days are lost; they are simply for a different kind of work.
The body sign and your own body
The same almanacs warned against surgery, pulling teeth or castrating animals when the moon was in the sign ruling that part of the body, because the part was said to bleed more. Some rural families still schedule tooth extractions by the signs.
We mention this as folklore only. Medical and dental appointments belong to your doctor's and dentist's judgment, not to the almanac.
Light of the moon, dark of the moon
The second half of the method is the moon's phase. From new moon to full moon, the “light of the moon”, the moon is waxing; from full moon to the next new moon, the “dark of the moon”, it is waning.
Waxing moon: crops that bear above ground: beans, corn, squash, tomatoes, lettuce and grains. The saying is that they grow up with the moon.
Waning moon: crops that bear below ground: potatoes, onions, garlic, carrots, beets, turnips and radishes. The saying is that they grow down as the moon goes down.
The ideal day combines both: a fruitful sign in the right phase. Potatoes in the dark of the moon with the signs in the feet, beans in the light of the moon with the signs in the breast. If the two conflict, most old gardeners let the sign decide and the phase come second. Our guide to the new moon ritual explains how the same phases are used in ritual work.
Temple Tip
Draw the month as a strip before you plant. Mark new and full moon, then write the sign for each day underneath. The good planting windows jump out at once: usually two or three short runs per month where a water sign meets the right phase. Plan the seed-starting around those, and let the barren days take the weeding.
Which almanac? Astrological versus astronomical place
Here is the detail that confuses many beginners. There are two different ways to say where the moon is.
The astrological (tropical) zodiac starts Aries at the spring equinox and divides the sky into twelve equal slices. This is the system of horoscopes and of most planting-by-the-signs tables, including the traditional Zodiac Man calendars.
The astronomical position names the constellation the moon is actually in front of. Because of the slow wobble of Earth's axis, the two now differ by nearly a whole sign.
The Old Farmer's Almanac prints both, which is why two gardening calendars can disagree by a day or two. Planting by the signs as it is practiced in the mountains uses the astrological place. Whichever you choose, use one system consistently for a season; mixing them makes the method meaningless.
Planting by the signs in fall: garlic, bulbs and clearing
Most writing about planting by the signs is about spring. Fall has its own traditions, and October and November are when many of them apply.
Garlic and onion sets. Hardneck garlic goes in a few weeks before the ground freezes. Sign planters look for the dark of the moon with the signs in Scorpio, a water sign that also rules below-ground growth in many tables, or in Pisces or Cancer if Scorpio falls in the wrong phase.
Spring bulbs. Tulips, daffodils and crocus are roots in the old logic, so they follow the waning moon, ideally in a water or earth sign.
Clearing and cover crops. Pulling spent plants, cutting brush and burning weed piles belong to the barren fire signs, especially Leo and Sagittarius. Cover crops such as winter rye are seeds that sprout above ground, so they go in with the waxing moon.
Harvest and storage. Root crops dug for storage and apples picked for keeping are traditionally gathered in the waning moon, when the plant is said to hold less water, and in a dry sign, so that they do not rot in the cellar.

Beyond the garden: shingles, fence posts and sauerkraut
The signs governed much more than the vegetable patch, and the side customs show how deeply the idea ran:
Roof shingles nailed in the light of the moon were said to curl up; in the dark of the moon they lay flat. Fence posts set in the dark of the moon were said to stay firm, while posts set in the light would work loose. Sauerkraut and pickles made with the signs in the bowels or the heart were said to go soft or smell. Hogs killed in the light of the moon were said to give fattier, curlier meat.
These beliefs were collected by Foxfire students and by folklorists across the Appalachian region in the twentieth century. Whether they hold is another matter; what they show is a complete way of ordering the year around the sky.
What the research says
The honest answer is that controlled studies have not shown a reliable effect of the moon's phase or sign on crop yield. Extension services that have written about the practice, including the University of Arkansas and North Carolina State University, present it as tradition, note the lack of scientific support and encourage gardeners to keep their own records if they want to test it.
There is a physical grain of truth in the moon story: moonlight is far too weak to drive photosynthesis, but the moon does move tides and some studies have looked at small effects on soil moisture and seed germination. None of this adds up to the specific claims of the Zodiac Man.
Planting by the signs does have practical side effects that help a garden. It forces you to plan, spreads work across the month, and gives weeding its own dedicated days. Many gardeners find it is the rhythm, not the moon, that improves their results.
Quiz: which sign-planting approach fits your garden?
Three questions to find out how deep into the signs you want to go.
Voices from practice
Gardeners who grew up with the signs often say they follow them less for the harvest than out of loyalty to a parent or grandparent who did the same, and that the almanac on the wall is part of how they remember them.
Newcomers to the method frequently report that the hardest part is the two zodiac systems, and that things got easier once they chose one almanac and stuck to it for a full season.
Practitioners who combine gardening with moon work often describe the barren days as the most useful discovery: weeding, pruning and clearing finally get their own place in the calendar instead of being done in a rush.
What we don't promise
We do not promise that planting by the signs will increase your yield, protect your crops from pests or make your garlic larger. There is no good evidence for that, and soil, water, sun, seed quality and timing against frost matter far more than the moon's sign.
What the method can offer is a structure: a monthly rhythm that links your garden to the sky and to a long line of rural gardeners. We also do not give medical advice: the old rules about surgery and the signs are folklore, not guidance.
Practically: how to work with this
- Get one almanac. A printed farmer's almanac or a reliable online moon-sign calendar. Decide whether you follow the astrological or astronomical place, and stay with it.
- Mark the month. Note new and full moon, then the sign for each day. Circle the water-sign days in the phase you need.
- Match crops to phase. Above-ground crops in the waxing moon, roots and bulbs in the waning moon.
- Give barren days a job. Weeding, pruning, cutting brush and clearing beds in Leo, Gemini, Aries, Sagittarius and Aquarius.
- Plant this fall. Garlic and bulbs in the dark of the moon, ideally in Scorpio, Pisces or Cancer, a few weeks before the ground freezes.
- Keep records. Write down what you planted, when and in which sign, and how it grew. After a season you will know whether the signs work for you.

Frequently asked questions
What does “the signs are in the feet” mean?
It means the moon is in Pisces, the sign the almanac's Zodiac Man links to the feet. Pisces is a water sign and counts as very fruitful for sowing.
What are the best signs to plant in?
The water signs Cancer, Scorpio and Pisces are traditionally the most fruitful. Taurus and Capricorn are good for roots, Libra for flowers and vines.
When should I plant garlic by the signs?
In fall, a few weeks before the ground freezes, in the waning moon and ideally with the moon in Scorpio, Pisces or Cancer.
Why do two almanacs show different signs?
One uses the astrological (tropical) zodiac, the other the moon's actual constellation. They differ by almost a sign. Traditional sign planting uses the astrological place.
Does planting by the moon actually work?
Controlled studies have not shown a reliable effect on yield. Many gardeners use it for the rhythm and planning it brings, and test it with their own records.
Is planting by the signs astrology?
It uses the zodiac, so it grew out of astrology, but in rural America it was practiced as farm know-how, printed in almanacs next to tide tables and frost dates.
