There are many who believe that planting their crops according to the phases of the moon and/or the zodiac will increase the success of their crops. But God nowhere in the Bible teaches us to live by the signs of the zodiac and moon phases. If fact, quite the opposite is said! Look in Isaiah 47:13-14. “You are wearied in the multitude of your counsels. Let now the astrologers, the stargazers, the monthly prognosticators, stand up, and save you from these things that shall come upon you. Behold, they shall be as stubble; the fire shall burn them; they shall not deliver themselves [let alone anyone else]…”

Astrology is the study that assumes and professes to interpret the influence of the heavenly bodies on an individual’s life. This is a form of idolatry. It is putting a humanly conceived idea ahead of or in place of the God who created the heavens (Romans 1:25). God forbids such worship as the “hosts of heaven” (II Kings 23:5).

Deuteronomy 28 is specific as to what God will do for those who will turn to and obey Him. He promises blessings beyond what a person can imagine, both physically and spiritually. Nowhere is astrology mentioned as one of the requirements for receiving His blessings. Please notice Jeremiah 10:1-2: Hear you the word which the Lord speaks unto you, O house of Israel: Thus says the Lord, Learn not the way of the heathen, and be not dismayed at the signs of heaven; for the heathen are dismayed at them.”

It has been observed that the moon has an effect on ocean tides and on some human and animal behavior. It may also have a slight effect on the germination of certain plants. But this does not mean that one should trust his whole planting schedule on which phase or what sign he is planting by. Planting can be done only when the elements are favorable. If, when a person is ready to plant, the day is warm and sunny, but he waits a few days—until he thinks the signs in the heaven are just right—and then it rains for a week or ten days straight, he may have lost all hope of even having a crop at all.
