The Influences Of The Moon On Plants

4 min read

Sowing and working with the Moon is to consider plants as living organisms, and not as inanimate objects that exist for the sole purpose of serving us.

Nature is an organization with a physical aspect and a spiritual aspect, it’s an Integral Being. The planet is a living being and the organism in which we live and, therefore, we humans are part of it.

To define a perfect relationship with nature, it is necessary to recover a conscious value of what we receive from the land, to become aware that the land gives us food, air, water, life and that, due to our arrogant attitude towards nature, we are causing destruction and putting so many species at risk…

There is a great disrespect for our Mother Earth, which has been treated as an object, a thing without conscience, we have ignored its spirituality, its heart, its body.

Signs of Intelligent Life

In ancient times, the elements were venerated with great respect and love, we thanked the food, the dawn, we greeted the animals, the trees, the rivers, we showed respect for the animal that was hunted, because its sacrifice would feed the whole tribe. The tree that was cut down deserved respect because its sacrifice would warm up an entire tribe. This spiritual awareness is a spirituality of nature.

We, humans, are one more species among all existing species, we are a collective body. We are part of this collective consciousness, we cannot continue to ignore our interconnection with the planet.

In food production, the influence of the moon on plants has been known to farmers since ancient times.

It is a millennial knowledge that the Chinese have, for example, about the cutting of bamboo and wood: to be carried out between the Waning Moon and the New Moon, when the sap and moisture content inside the trunks is lower. Using this knowledge it is possible to work with the rhythm of Nature and use it for the benefit of plants.

The Moon goes through four phases: Waning, New, Waxing, and Full Moon. Each phase lasts seven days.

Crescent Moon

Phase in which the sap is attracted upwards, towards the leaves, favoring the growth of the upper part of the plant.

Favorable period for planting cereals, fruits, and flowers and harvesting vegetables.

Good time to make grafts and prepare the soil with mulch.

Full Moon

Harvest medicinal plants and fruits – the fruits are more succulent due to the greater amount of sap found in the fruits. Planting advised against.

Waning Moon

At this stage the strength of the sap decreases, going to the bottom of the plant.

Start planting root plants, such as beets, carrots, onions, potatoes … Harvest the roots and pods as the plant has less sap which facilitates cooking. Harvest corn, pumpkin and others for storage, because it resists the attack of the weevil more.

Good time to prune.

Harvest the seeds a few days before the New Moon.

New Moon

At this stage, the sap reaches its maximum receding peak. Plants have low resistance to pests. Planting advised against.

From the above we derive the following rules: that between the waning moon and the new moon everything that goes “below the ground” (roots, tubers, rhizomes and edible bulbs) must be planted and, that between the crescent and the full moon, must – plant everything that goes “above the ground” (leaves, flowers and edible fruits).

The Biodynamic Moon

The relationship between the moon and the constellations also determines what we should do in the field (and also at home!). There is a relationship between the position in which the moon is in the constellations and the organs of the plants that are most active.


If the Moon is in a Fire Element Constellation (Aries, Leo, and Sagittarius) it’s a fruit day and therefore it is the fruit of the plant that is most potentiated. That is why it is time to work on the crops that will give us the fruit – courgettes, tomatoes, pumpkins, … It is also during these days that we must do the pruning so that we can have vigorous fruit.


If the Moon is in an Earth Element Constellation (Taurus, Virgo, Capricorn), it is a root day and that is why it is the roots that are most active. These days we must sow, transplant and care for root vegetables or tubers.


If the Moon is in a Water Element Constellation (Cancer, Scorpio, Pisces) the day is called a leaf, and therefore it is the leafy vegetables that we must pay particular attention to – cabbages, lettuce, parsley,…. For harvesting this type of vegetable, however, it is preferable to choose days of fire or air so that they are better preserved.


When the Moon is in an Air Element Constellation (Gemini, Libra, Aquarius), we should take care of the plants that we are interested in obtaining the flowers such as cauliflower, broccoli, and flowers in particular.
