Ascension / Descension Cycle of the Moon (27.32 days)
This is often confused with the waxing/waning Moon cycle ie; the phases of the moon from New Moon to Full Moon and back to New Moon.
Ascending/Descending Moon is a mini-cycle of the Sun’s varying heights in the sky between Summer and Winter when in swings between the Tropics of Capricorn in the Southern Hemisphere and Cancer in the Northern Hemisphere.
Our Summer Solstice finds the Sun at its highest path in the southern sky. This is called Peak South or Peak Ascension. Our Winter Solstice finds the Sun at its lowest path across our Northern skies.
When the Sun ascends South in our Spring and Summer, the Earth breathes out and plant growth surges upwards. The Moon has a similar movement in the sky, but much faster than the sun. She moves between the Tropic of Capricorn and the Tropic of Cancer in two weeks rather than 6 months. When the Moon is ascending in the sky, plant vitality moves into the upper reaches (like a mini Spring and Summer). When the Sun is descending in the sky, the Earth breathes in and the plant’s main activity withdraws into the root zones. So to with the Moon’s descension (like a mini Autumn and Winter).
There are higher tides at Peak Ascension of the Moon and bulkier or more rapid plant growth. The fortnight of Moon ascending is considered favourable for grafting and application of atmospheric sprays such as Horn Silica (BD501), but not for pruning. As the moon descends over the next fortnight, the increased vitality within the soil make it favourable for spraying out the Biodynamic soil sprays, for compost making and transplanting.
In moving up and down the sky like this, the Moon’s daily path moves from below the Sun’s path to above it and back again. It crosses it twice a month, once as it is ascending and once when descending. These crossing points are called nodes and are when eclipses can occur.
It is unfavorable for planting 2 hours either side of nodes and 12 hours either side of an eclipse.
