Lunar gardening, or planting by the moon's phases, is an ancient practice gaining modern traction. For outdoor plant boxes, certain plants thrive under lunar influence. Leafy greens like lettuce and spinach excel during the waxing moon, while root vegetables such as carrots and radishes prefer the waning phase. Herbs like basil and parsley also respond well to lunar cycles. To maximize growth, align planting with moon phases: sow seeds two days before the new moon for leafy crops and during the third quarter for roots. This method not only boosts yield but also promotes sustainable gardening. Experiment with these plants to harness the moon's natural rhythm in your outdoor plant boxes.
