For centuries, farmers and gardeners have looked to the stars for guidance. In biodynamic gardening, the Moon’s journey through the twelve constellations of the zodiac is more than symbolic—it influences the very rhythms of life in the soil and plants. Each sign carries particular qualities that align with different parts of the plant, roots, leaves, flowers, and fruits/seeds.
For over a year and a half, I’ve been writing a daily biodynamic message for Tetragrammaton.com, a website curated by Rick Rubin. These messages trace the Moon’s journey through the constellations, offering insights into how cosmic rhythms influence life on Earth—especially in the garden. In this post, I explore the twelve zodiac signs and how, when the Moon passes through each one, it subtly steers the kinds of activities best supported in the biodynamic calendar—whether sowing root crops, harvesting leafy greens, or simply listening to the land.
When the Moon is in Aries, we feel a surge of energy and initiative—a perfect time to sow seeds for plants that bear fruit above ground. The fiery, pioneering nature of Aries supports crops like tomatoes, courgettes, peppers, and beans. There’s an urgency in the air; quick actions and bold decisions suit the day. It’s a good time to start something new in the garden—build a bed, erect a trellis, or experiment with a new planting technique. Just beware of impatience or rushing.
Taurus brings calm, steadiness, and a love of the physical earth. These are excellent days for root work—sowing, planting, or harvesting root vegetables like carrots, parsnips, beets, and potatoes. The soil feels particularly alive and generous under Taurus. It’s also a favourable time for tending compost heaps, preparing herbal teas or plant extracts, and working slowly with intention. What you plant now may yield steady, nourishing results.
Gemini’s airy, curious qualities make these days light and mobile. Focus on flowering plants—deadhead roses, scatter wildflower seeds, or tend to medicinal blossoms like chamomile, lavender, and calendula. These are sociable gardening days—ideal for sharing knowledge, involving others, or updating your garden journal. Grafting, pruning, and experimenting with cuttings all benefit from Gemini’s quicksilver nature.
When the Moon moves through Cancer, the garden calls for nurturing. Leaf crops such as lettuce, spinach, chard, and brassicas respond well to sowing or harvesting now. Moisture levels tend to be high—making this a good time for watering, weeding, or applying liquid composts. There’s also a strong home-and-hearth energy, so tending your kitchen garden or window boxes is especially rewarding. Trust your instincts—Cancer days are deeply intuitive.
Leo’s solar rulership and vibrant presence bring warmth and confidence to the garden. These are bountiful days for fruiting plants—especially those that thrive in summer heat like squashes, melons, aubergines, and sunflowers. There’s a festive mood in the garden—ideal for sharing harvests, saving seeds, or hosting gatherings. Let your garden express itself boldly—prune with flair, or beautify your space.
Virgo brings clarity, refinement, and a love of quiet service. It’s a perfect time to tend root crops with precision: thin carrots, harvest beets, or plant garlic. These days are suited to meticulous work—clearing beds, labelling seeds, refining compost blends, or making biodynamic preparations. The Virgo Moon supports healing herbs, medicinal roots, and herbal remedies—bringing order and care to your garden’s deeper layers.
Libra brings balance, elegance, and a love of beauty. Focus on symmetry and harmony in the garden—sow sweet peas, tend flowering herbs, or rearrange borders for better flow. Libra days are good for aesthetic work: installing paths, placing statues, or planning companion planting. You might find yourself drawn to artistic touches—colour combinations, trellises, or mandala beds. These days also favour social gardening—inviting conversation and collaboration.
Scorpio connects us to the mysteries below the surface. Leaf crops benefit now, but there’s also a deeper opportunity: composting, transforming, and working with decay and regeneration. Prune trees, bury biodynamic preparations, or inoculate soil with fungi. These are powerful days for subtle work—making fermented teas, harvesting nettles, or engaging in spiritual gardening practices. The garden is not just alive—it’s evolving.
Sagittarius inspires freedom, expansion, and generosity. Fruiting crops like grapes, pumpkins, and climbing beans thrive when planted or harvested now. These days invite you to explore: try a new plant variety, redesign a growing space, or dream up next year’s garden plan. There’s a wildness in the air—let vines stretch skyward and ideas roam. Fire up your compost, and feed your soil with vision.
Capricorn lends endurance, wisdom, and a focus on long-term structure. Root crops like Jerusalem artichokes, horseradish, and celeriac are in their element. It’s an ideal time for structural work—building paths, repairing fences, or laying out permanent beds. Capricorn supports serious composting, mulching, and tending to perennial plantings. This is where biodynamic gardening meets legacy—what you do now shapes the seasons to come.
Aquarius brings innovation, originality, and a hint of the unconventional. Flowering plants benefit, especially wild or airy ones like teasels, fennel, or bee-friendly herbs. These are good days for experimenting—setting up irrigation systems, testing new composting methods, or integrating permaculture design. Aquarius supports collective work—community gardens, seed swaps, or online sharing. Bring fresh ideas into your space, and let your garden surprise you.
Pisces closes the zodiac wheel with deep sensitivity and spiritual connection. Leafy herbs and greens respond well—especially those used in healing, like valerian, mint, and lemon balm. These are ideal days for gentle tasks: watering, misting, or making flower essences. The garden may feel like a dreamscape—soft, lush, and slightly blurred. Trust intuition, and allow space for reverie. Gardening under Pisces reminds us that the invisible is as real as the visible.
