That's a very, very interesting theory Searcher.
Obviously medieval people linked phases of the moon to tides, even if they didn't know why. Roger Bacon's theory was that the moon caused the tides in oceans, but he believed this was because the rays of light from the moon “raise vapours” from the sea, which cause the waters to move. When the moon was overheard, these rays evaporated the water, which made the tide recede.
The same theory was deemed to be responsible for the movement of much water, and even night-time dew. The belief was that when moon was waning it would draw water deeper into the soil, and when is waxing (becoming a full moon) the water was being drawn up and out of the soil.
The phase of the moon was important for agriculture, such as when to plant seeds, for this reason. An agricultural treatise from 15th century Spain states that in March, “melons, cucumbers, gourds, oats, sorghum, onions and green beans can be sown in the waning moon. Cabbage seed and radishes in the old moon. Green beans and sorghum and spelt can be sown in the new moon. Graft fig trees and other trees in waxing moon.” (You are not allowed to view links.
