The earliest humans probably ascribed special powers to the moon. In fact, the celestial body has an influence on the natural rhythm on earth, as can be easily seen from phenomena such as the ebb and flow of the tide. Some gardeners even swear by matching the care of plants to the lunar calendar and watering and fertilizing on certain days. This would save water and fertilizer, they say. Is there actually anything to this theory?

How does watering work according to the lunar calendar?
Watering according to the lunar calendar works according to a very specific principle: You can only water your indoor plants on certain days, the so-called water or leaf days. These days change every month and every year, but can be viewed on special calendars. From an astrological point of view, the moon is in one of the three water signs Cancer, Pisces or Scorpio on these days, which it passes through several times in a month. If you water on one of these days, the growth of green plants and their leaves is stimulated, so that they thrive all the more magnificently. On the other hand, watering is forbidden on one of the so-called air days when the moon is in one of the zodiac signs Gemini, Aquarius or Libra. According to some astrologers, watering on such days increases the risk of pest infestation.
Is there actually something to it?
Whether watering works according to the lunar calendar has not yet been scientifically proven. These are astrological beliefs that you may or may not believe in. In fact, so far it has only been possible to determine that the individual phases of the moon - which in turn have nothing to do with the signs of the zodiac - have a minor influence on the growth of plants. It is therefore better to water your indoor plants according to their individual needs and, if possible, use stale water at room temperature.

Many indoor plants, especially those species from tropical regions, tolerate a lukewarm shower from time to time. This not only washes the dust off the leaves, but also ensures higher humidity and makes it difficult for any pests to nest.
