Basics
Understanding Moon and calendar
Root, leaf, flower and fruit days
The biodynamic planting calendar assigns every day to a part of the plant: root, leaf, flower or fruit. What decides is the constellation in front of which the Moon stands. The system goes back to Maria Thun.
Ascending and descending moon
The moon does not only run through its phases of light — it also climbs higher in the sky and sinks again. This rise and fall is called the moon’s course, and in the biodynamic calendar it decides when to harvest and when to plant.
Moon phases in the garden
From new moon to new moon the moon’s light grows and fades again. Gardening tradition puts certain work into the waxing moon and other work into the waning one. It uses the full moon for harvesting herbs.
