Biodynamic gardening: planting by the moon

Biodynamics is a new idea for many people. It goes beyond typical organic gardening and treats the farm or garden as a living whole rather than something we simply act upon. Biodynamic growers also pay attention to the rhythms of the cosmos – especially the moon.

We know the moon’s gravity drives the ocean tides. Biodynamic and traditional moon-gardening practices hold that the moon’s cycle also influences when it’s best to sow, plant, tend and harvest. It’s a tradition rather than settled science, but it gives a lovely rhythm to the gardening year and a wonderful way to connect children with the sky.

Learning to plant by the moon

You don’t need to be an astronomer. Gardeners have long followed almanacs and sowing guides without knowing everything about their region or seasons; in the same way, moon-planting calendars can guide you on when to sow, harvest or rotate crops.

Looking after the soil

Crop rotation is essential for healthy soil. Growing the same crop in the same place year after year depletes the soil, while rotating crops keeps it healthy. Composting is another fantastic way to improve soil, and biodynamic growers make special preparations to enrich their compost.

Some biodynamic calendars go further and follow the moon’s passage through the constellations, assigning days to leaf, fruit, root or flower crops. If that appeals, start with the moon phases first and add more detail later.

Companion planting

Biodynamics, like organic growing, also looks at how plants support one another. Some herbs and flowers attract helpful insects or deter pests, and planting them near vegetables can protect crops and help pollination.

A traditional rhythm to try

Begin slowly – don’t try to master it all at once. A simple traditional guide to the moon phases:

• New moon to first quarter: sow leafy crops such as lettuce, cabbage and spinach.
• First quarter to full moon: sow crops that fruit above ground, such as beans, peas, squash and tomatoes.
• Full moon to last quarter: plant root crops such as carrots, potatoes and onions.
• Last quarter to new moon: a time for weeding, pruning, harvesting and preparing beds rather than sowing.

Final thoughts

Following the moon takes a little practice, and it’s a beautiful way to slow down and notice the sky with children. Our Moon Workbook is a great companion for learning the phases together.
