According to Farmers' Almanac tradition, when the moon is in the appropriate phase and place in the zodiac, it's widely believed that activities will be more fruitful or lead to improved results. The period between the new and full moon (first and second quarters) is considered as the best time to perform tasks that require strength, fertility and growth. The period between the full and new moon (third and fourth quarters) is best for harvesting, retarding growth, etc. Consideration is also given to the relationship the moon has with the 12 ruling signs of the zodiac.
