I remember my mother would plant her garden by the phases of the moon. I have never been a convert for moon phase gardening. My method has been if I have time to plant between wind, snow, soil temperature, or rain, I will.
Moon gardening goes by the phases of the moon which is on a 29.5-day cycle. When the moon is waxing (growing light between the new moon to the full moon), plant or transplant crops that produce above ground like tomatoes and peppers. When the moon is waning (the light is growing dimmer between the full moon to the new moon), plant crops that produce below ground like beets and onions. Also, harvest during a waning moon when the photosynthesis is slowest and less fluid moving in the plant. It also helps with shelf life.
We do know that plants like humans, animals, and birds have a circadian rhythm and moonlight affects it. Some plants open their blossoms after sunset, however, increase bloom production in the full moonlight like the moonflower and four o’clock. The Werewolf plant sends out pollen in time of the full moon.
Moon gardening goes back to the Celts in England. Some think the structure of Stonehenge helped the people in the timing of crop planting.
I light of everything, if you wish to garden by the moonlight, go for it. There is no negative aspect to doing this.
