* Traditions disagree on this rule — it counts at half weight.

Sunday 9 August — 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.
