There's nothing new under the sun, in this case, there's nothing new under the moon.
Gardening by the moon is an old Folklore tale that a lot of gardeners swear by. Moon Phase gardening or Gardening by the moon simply means the idea that the moon's lunar cycle affects plant growth according to the Farmers Almanac.
There are two periods in the Lunar Cycle: The New Moon and the Full Moon. The key is to know which plants to grow depending on the phases of the moon. When the moon is full...plant Above ground plants (peas, tomatoes, corn, greens, etc). When the moon goes dim...plant below ground plants (potatoes, carrots, turnips, etc.).
The moon's gravitational pull creates tides in the oceans creating more moisture in the soil, which encourages growth. Roots grow downward in the direction of the gravitational pull and stems grow in the opposite direction (Almanac). In other words, plants grow in the response to gravity.
Folklore or not, we all respond to nature in one way or another. As long as we love and nurture our gardens, a great harvest will always be the end result.
Happy Moon Gardening !🌙 🍅🌶🥒🥕🥦
