Planting by the Moon is an age-old practice that gardeners and farmers have used for hundreds of years. The Old Farmer’s Almanac includes the Moon phases in its planting calendars, and many old-time farmers swear it results in healthier, more productive gardens. Here’s how itworks.
What Is Planting by theMoon?
From what we’re seeing, many trend watchers are confused about Planting by the Moon. No, it’s not about gardening at night—or planting in your PJs!
It’s a simple practice based on the idea that the cyclesof the Moon affect plant growth. Just as the Moon’s gravitational pull causes tides to rise and fall, it also influences moisture levels in thesoil.

Seeds absorb more water between the new Moon and the full Moon because moisture is increasingly drawn to the soil’s surface during this period. This extra moisture causes seeds to swell, promoting stronger germination and better-establishedplants.
Throughout history, people have planted according to the Moon’s phases—from the Ancient Egyptians to the Romans. Pliny the Elder, a Roman historian, wrote about the Moon’s influence on agriculture. Even in completely different regions like China and Africa, the Moon’s cycles were considered in plantingpractices.
Many Native American tribes followed the lunar calendar for planting, as did the Founding Fathers of the United States. Benjamin Franklin, the father of the modern Almanac, published the lunar calendar to help Colonial farmers, a tradition that continues with The Old Farmer’s Almanac.
Today, some modern farmers, especially those interested in sustainable gardening, still consider the Moon cycle when planting. One example is agriculturalist John Jeavons, the father of the biointensive gardeningmovement.
Planting by the MoonCalendar
To discover WHEN to plant by the Moon, see The Old Farmer’s Almanac’s Gardening Calendar.
This calendar, updated every year, calculates the correct Moon phase for all your common vegetables, herbs, and fruit.
Note that Moon phase gardening is reasonably straightforward. It considers two periods of the lunarcycle:
- The time between the new Moon and the full Moon (the waxing of the Moon)and
- The time between the full Moon and the new Moon (the waning of theMoon).
It’s best to plant certain types of plants during the waning of the Moon and other types during thewaxing.
How to Plant by the Moon’sPhases
To plant by the Moon, follow theseguidelines:
- Plant your annual flowers and fruit and vegetables that bear their harvest above ground(such as corn, tomatoes, watermelon, and zucchini) during the waxing of the Moon. This means from the day the Moon is new to the day it is full. As the moonlight increases night by night,plants are encouraged to grow leaves andstems.
- Plant flowering bulbs, biennial and perennial flowers, and vegetables that bear crops below ground(such as carrots, onions, and potatoes) during the waningof the Moon. This means from the day after it is full to the day before it is new again. As the moonlight decreases night by night, plants are encouraged to grow roots, tubers, andbulbs.
The Moon, Plants, andGravity
The Moon also impacts plant growth through geotropism—how plants grow in response to gravity. Roots grow downward in the direction of gravitational pull, and stems grow in the opposite direction (i.e., upwards). This behavior can be easily demonstrated with potted plants. Lay one on its side, and the stem will grow upwards. Or, consider a tulip bulb: if you plant the bulb incorrectly with the pointed end down, it will turn around and send its shoots upward, even though it’s in total darkness.

Frequently AskedQuestions
Is this the same thing as Best Days by theMoon?
No, if you came to this page looking for our Best Days calendar, go to the complete Best Days Timetable. Planting by the Moon is astronomical, depending onthe Moon’s phase. Astronomers base their studies on research and observation. What folks call the “Best Days by the Moon” is astrological, based on the Moon’s positioning and a belief that its position in the zodiac affects events on Earth.
Do you have scientific evidence that Planting by the Moon works? While there is some evidence that the Moon phases might have a small impact on plant growth, other studies say it’s folklore. (We say, doesn’t folklore always contain a kernel of truth?) Many experienced farmers swear by this practice and have had great success. Be realistic and remember that many factors considerably influence plant growth: soil quality, sunlight, water, air circulation, weather conditions, plant varieties, and pestmanagement.
What if the Moon cycles don’t align with the time I want to plant?
We hear you! If your goal is to get your seeds in the ground as soon as possible and not wait for the Moon phase to align, it’s a judgment call. If you can only garden on the weekends, get your seeds in the ground whenever your busy schedule allows. Here at the Almanac, we’re a practical bunch. It is a fun and traditional practice, and we plant by the lunar cycle when it makes sense for the rest of our lives.
Seeds will certainly grow perfectly well any time of the month they are planted if they’re given the nourishment and care that they need. Planting by the Moon is a way to capitalize on the magnetic and gravitational impact of the Moon.
