Watering plants by the moon
Watering plants by the lunar calendar: the next favorable day is Sunday 8 November. Score calendar, goals and the traditional rules behind every date.
Why by the moon?
The watering rule comes from Maria Thun’s biodynamic sowing calendar: on leaf days — when the moon stands in a water sign (Cancer, Scorpio, Pisces) — plants are said to take up and use water best.
Flower days (air signs) count as poor watering days instead: water is said to evaporate rather than serve the plant. In practice that means a good watering day comes around every two to three days by itself.

Why 80 points on Sunday 8 November?
The MoonScore aggregates traditional lunar-calendar rules (Paungger/Poppe, folk tradition, Maria Thun). It does not represent any scientifically established effect.
* Traditions disagree on this rule — it counts at half weight.
When is the next good day for watering plants?
Sunday 8 November — Very favorable (80/100).
When should you water plants according to the lunar calendar?
According to Maria Thun, leaf days are the best watering days — days when the moon is in a water sign (Cancer, Scorpio, Pisces). Plants are said to take up water best then.
On which days should you avoid watering?
According to Maria Thun, flower days — the moon in an air sign (Gemini, Libra, Aquarius) — are unfavourable for watering: the water is said to benefit the plants less then.
