Gifts for the Soil

With biodynamics we are gifting to the soil a concentration of forces and a kind of "sweetness" that naturally wouldn't occur by chance in nature. And that is the secret of alchemy: taking things to their fulfillment when Nature, left to herself, could not do so.

Gifts for the Soil - The Josephine Porter Institute

The biodynamic preparations represent a gesture of expansive life and love for the source of life itself, as expressed especially in flowers which seek to return to their source. It's as if the growth of plants is inspired not by mere chemistry, but a real inner affinity for light, a love for the Sun itself. 

If it were not for bees, much of what flowers produce as nectar would evaporate and disappear back into the atmosphere. Where does all that sweetness go? In biodynamics, we seek to retain some of this nectar in the form of the biodynamic preparations. We gather fresh blossoms, ideally, and place them inside sheaths that naturally contain the process the medicinal herbs influence. Then we hang these on the east side of a building, where the hanging preparations can ripen almost like fruits in the mild morning sun. 

In alchemy, the source of fertility is considered to be dew. Rain is necessary, yes, but there is a fattening quality in the dew that enriches and adds combustible oil. When we let the biodynamic preparations hang somewhere that dew collects, but not where the afternoon sun might scorch away this precious fertility, day by day the preparations inhale a little more dew, and then become dry to the touch on the outside. This rhythmic inhalation and exhalation of dew means that the preparation continues to assimilate more and more from the cosmos as it ages. Steiner gives the indication to bury the winter preparations somewhere that the sun shines (morning - east, in the northern hemisphere) but the snow doesn't melt (shaded by midday), so this corresponds, generally speaking, with the eastern side of a building.

As many of you likely know, a fig is technically a flower that never opens. The sweetness inside is the nectar that is retained as the excess water evaporates through the tiny hole at its end. Inside the fig you see a natural form of "honey" forming. In the biodynamic preparations, it is almost as if the flowers waken to life -- briefly -- every day and produce a little more nectar. When you find a bladder filled with yarrow blossoms, what is really happening? We are making a yarrow fruit which doesn't exist in nature! We are containing and ripening the floral process much like how a fig produces a honeylike substance inside its unopened flower. 

With biodynamics we are gifting to the soil a concentration of forces and a kind of "sweetness" that naturally wouldn't occur by chance in nature. And that is the secret of alchemy: taking things to their fulfillment when Nature, left to herself, could not do so.

Frequently Asked Questions

What are biodynamic preparations?

JPI lists nine core biodynamic preparations: BD 500 horn manure, a soil-directed spray; BD 501 horn silica, a fine foliar spray; BD 502–507, the six compost preparations; and BD 508 horsetail (Equisetum arvense), used as a fresh-tea foliar or fermented-tea soil spray. Growers use these small quantities of specially prepared natural materials alongside good organic and ecological practices to support living soil, compost, and plant vitality. Each preparation has its own amount, mixing, target, and timing; follow the current JPI instructions: https://www.jpibiodynamics.org/pages/making-using-bd-preps

How do biodynamic preparations benefit the soil?

The complete BD 502–507 set helps produce biologically active compost for soil. In a 2026 controlled study using Italian-supplied preparations, mature compost treated with all six supported greater growth of selected compost-associated bacteria at 120 days than untreated compost. Water-soluble extract from the treated compost supported about tenfold more growth than extract from untreated compost at that time.

Why is dew important in biodynamics?

In this article, morning dew is part of the gentle outdoor ripening environment for hanging herbal preparations. The article describes a seasonal rhythm of moisture, mild morning light, and shelter from stronger afternoon sun; follow the specific JPI instructions for each preparation.

What role do flowers play in biodynamic practices?

Flowers supply the plant material for four compost preparations: yarrow (BD 502), chamomile (BD 503), dandelion (BD 506), and valerian (BD 507). Each is processed by its own method before the finished preparation is used with compost. This article portrays their ripening as a gift of floral vitality to the soil.
