Sowing by the Moon: the rules of traditional farming

For centuries, in the European countryside, the calendar of farm work was set not only by the seasons but also by the phases of the Moon. Sowing, pruning, felling timber, racking wine: each task had its lunar moment, fixed by rules passed on by word of mouth and in printed almanacs. These rules belong to rural tradition and to the history of material culture; they have found no solid confirmation in modern agronomic research, but they say a great deal about the ancient relationship between farmers and the sky.

Ancient sources

The first written instructions date back to antiquity. Hesiod, in the Works and Days, composed around 700 BC, lists the days of the lunar month favourable or unfavourable to various tasks. In the second century BC Cato the Censor, in De agri cultura, recommended uprooting and cutting timber during the waning Moon, after midday and when no south wind was blowing. Similar instructions are found in Varro and Columella, authors of treatises on country life.

Pliny the Elder, in his Natural History, devotes ample space to lunar rules for farming and for felling trees, reporting the opinion that timber cut at the new moon resisted woodworm better. In the late empire Palladius, with his Opus agriculturae arranged by months, passed these prescriptions on to the Middle Ages. The calendar structure of his work made it a model for many later almanacs.

Waxing and waning in the fields

In Italian peasant tradition the general rule distinguished the two halves of the cycle. During the waxing Moon people sowed above all the plants whose aerial part is harvested, such as cereals, legumes and leafy vegetables, because the sap was thought to rise upwards. During the waning Moon they preferred root and bulb plants, pruning and the tasks meant to slow down growth. Local variants were countless and often contradictory.

Felling timber was perhaps the field in which the lunar rule was observed most strictly. Wood cut in winter under a waning Moon was believed to be drier, more durable and less likely to rot or be attacked by insects. The same conviction is found in the forestry traditions of many Alpine and Apennine areas, where woodcutters handed it down from generation to generation together with their working techniques.

In the cellar and beyond

The cellar too followed the Moon. According to tradition, wine was to be racked and bottled during the waning Moon, when it was thought to be clearer and less prone to unwanted fermentation. Similar rules concerned the making of preserves, the salting of meat and the production of vinegar. This was knowledge handed down within families, often accompanied by dialect proverbs that fixed its timing.

In the twentieth century some of these ideas were taken up and systematised by biodynamic agriculture, born from the lectures given by Rudolf Steiner in 1924, which introduced sowing calendars based on the position of the Moon in the constellations. Experiments designed to test a measurable effect of lunar phases on plant growth have produced meagre or contradictory results, and the scientific community does not regard any influence of this kind as proven.

The lunar rules of traditional farming should therefore be seen as cultural heritage rather than technique. They bear witness to an age in which the sky was the first calendar, and they preserve a vocabulary, an oral memory and a way of observing nature that historians and ethnographers continue to gather and study with care.
