Gardening by the phases of the moon is a technique that can speed the germination of your seeds by working with the forces of nature.
How does lunar planting work?
Isaac Newton established the laws of gravity, which proves the tides are affected by the gravitational pull of the moon. The pull of the moon is stronger than the sun because, even though the sun is larger, the moon is closer to the earth. The strongest effect is felt when the moon and sun pull from the opposite sides of the earth, at the full moon phase, although it also creates high tides when they are on the same side (at the new moon) as well."The gravitation of the passing moon pulls the nearest body of water a little away from the solid mass of earth beneath it, and at the same time pulls the earth a little away from the water on the farthest side. In this manner the moon sets up two tidal bulges on opposite sides of the earth."
These same forces affect the water content of the soil, creating more moisture in the soil at the time of the new and full moon. This increased moisture encourages the seeds to sprout and grow.Dr. Frank Brown of Northwestern University performed research over a ten-year period of time, keeping meticulous records of his results. He found that plants absorbed more water at the time of the full moon. He conducted his experiments in a laboratory without direct contact from the moon, yet he found that they were still influenced by it.
Rudolf Steiner was the founder of the anthroposophical movement, which sees a correlation between science, nature, universal laws and spiritual concerns. Out of this movement the Biodynamic methods of planting were developed. He established a relationship between the elements of earth, air, fire, or water that corresponded to specific parts of the plants. Earth corresponds to root, water to leaf growth, fire to seed production, and air corresponds to flowers. Hence, when planting crops for their fleshy roots, you would plant them in an earth sign, and so forth.
Biodynamic methods are based on the heliocentric, or astronomical, position of the moon. This system is more complicated and also takes into consideration eclipses, trine, apogee and perigee as well as descending and ascending moons. John Jeavons, author of "How to grow more vegetables…" adds the influence of the increasing or decreasing moonlight on the growth of plants. When the moon is in it's waxing phases the " increasing amount of moonlight stimulates leaf growth", and " as the moonlight decreases the above ground leaf growth slows down. The root is stimulated again."
