May 2023 – Gardening by the Moon, Biodynamic Planting Guide

Please keep in mind, that Gardening by Moon Phase and Gardening by Moon Zodiac Sign are two different/independent biodynamic systems and they might give you different or contradictiory gardening recommendations.
- a) Each Moon Phase (except Full Moon and New Moon) lasts about 1 week
- b) Each Moon Zodiac Sign lasts about 2.5 days
Try to experiment with these two systems to find which recommendations suits you the most.
2) Tropical (Astrological) x Sidereal (Astronomical) Zodiac:
(1-2 days difference in Leaf, Fruit, Root and Flower days)
There are two different zodiacs for determining the Moon Sign:
- a) Tropical zodiac (Astrological) is based on the seasons – Vernal Equinox is fixed as 0° Aries (The 1st Fruit day)
- b) Sidereal zodiac (Astronomical) takes into account Precession of Equinoxes and shifts 0° Aries back by cca 1-2 days. Maria Thun who was an authority on biodynamics was using this Sidereal zodiac
Try to experiment also with these two zodiac systems to find which system suits you better.
