The only way to know for sure is to give moon phase gardening a try. After all, what can it hurt? (And it just may help!) Let’s learn a little more about how to garden by the moon.
How to Plant by Moon Phases
When the moon is waxing: This is the time to start planting annual flowers such as marigolds, nasturtiums, and petunias. Why? During the waxing of the moon (the period extending from the day the moon is new to the day it reaches its fullest point), the moon pulls moisture upwards. Seeds do well during this time because moisture is available at the surface of the soil. This is also the time to plant above-ground vegetables such as:
Beans
Tomatoes
Melons
Spinach
Lettuce
Squash
Corn
Don’t plant below-ground plants during this time; according to old-timers, the plants will be full and leafy on top with little growth under the ground. When the moon is waning: Below-ground plants should be planted when the moon is waning (from the time it reaches its fullest point to the day just before the full moon). This is the period when the moon’s gravitational pull decreases slightly and roots grow downward. Take advantage of this time to plant flowering bulbs such as iris, daffodils, and tulips and vegetables like:
Potatoes
Turnips
Beets
Onions
Radishes
Carrots
When the moon is dark: Don’t plant anything when the moon is at its darkest point; this is a resting period and plants won’t do well. However, many gardeners say this time of slow growth is ideal for getting rid of weeds. The Old Farmer’s Almanac offers a Moon Phases and Lunar Calendar here.
