Which constellations correspond to root, leaf, flower, and fruit work?

Earth constellations Taurus, Virgo, and Capricorn support root work; water constellations Cancer, Scorpio, and Pisces support leaf work; air constellations Gemini, Libra, and Aquarius support flower work; and fire constellations Aries, Leo, and Sagittarius support fruit and seed work.

What did Sherry Wildfeuer observe in the four-plot timing trial?

The earth/root-timed plot produced more beets and carrots than one orange crate could hold, with especially balanced form. Calendula in the fire/fruit plot ripened, dropped, and germinated its seed earlier than calendula in the root-timed plot.

How can a grower apply Stella Natura timing repeatably?

Use the Moon’s current astronomical constellation, allow the calendar’s four-hour transition period at each boundary, favor the middle of the constellation when possible, and record sowing, cultivation, spraying, harvest quantity, form, and ripening.

What preparation-making sequence did the 2012 JPI Intensive teach?

Participants examined bovine organs, filled and buried preparation vessels, recovered and processed mature preparations, made Barrel Compound, practiced pest ashing, and followed the four-year horn-silica cycle from annual lifting and reburying through final processing.

Applied Biodynamics — Issue 080 (Spring 2013)

Issue 080 records Sherry Wildfeuer’s four-plot root, leaf, flower, and fruit timing trial, the astronomical method behind Stella Natura, and the complete hands-on sequence of JPI’s 2012 preparation-making intensive.

Applied Biodynamics No. 80 joins two forms of practical training: Sherry Wildfeuer’s long work with elemental and cosmic planting rhythms, and JPI’s full-process 2012 preparation-making intensive. Both articles show biodynamics advancing through disciplined timing, side-by-side comparison, careful observation, and repeated hands-on practice.

In “Earth, Water, Air, and Fire: Working with the Elements and the Cosmos,” Abby Porter interviews Wildfeuer, founding editor of the Stella Natura Biodynamic Planting Calendar. The working correspondences are stated clearly: Taurus, Virgo, and Capricorn are earth/root constellations; Cancer, Scorpio, and Pisces are water/leaf constellations; Gemini, Libra, and Aquarius are air/flower constellations; and Aries, Leo, and Sagittarius are fire/fruit-and-seed constellations.

Wildfeuer’s formative Goetheanum experiment used four adjacent plots, each about ten feet wide and planted with the same range of root, leaf, flower, and fruit crops. One plot was cultivated and sprayed only during earth/root periods, one during water/leaf periods, one during air/flower periods, and one during fire/fruit periods. Each time the Moon entered a new constellation, the corresponding plot received cultivation and either BD 500 Horn Manure or BD 501 Horn Silica.

The plants appeared uniformly healthy during growth, while harvest made the timing response visible. Beets and carrots from the earth/root plot exceeded a full orange crate and showed especially balanced, beautiful form. In the calendula comparison, seed in the fire/fruit plot had ripened, fallen, and germinated before the root-plot blossoms had finished ripening. These clear contrasts established a repeatable model for growers: hold crops and management structure steady, vary the timing, harvest each plot separately, and record yield, form, ripening, and seed behavior.

Wildfeuer also explains the calendar method. Stella Natura follows the Moon through the constellations as they appear in the present astronomical sky, where constellations occupy unequal spans. A four-hour transition period is placed at constellation changes, and work is best scheduled when the Moon is nearer the central area of a constellation. This provides a consistent field protocol for testing root, leaf, flower, and fruit indications over successive seasons. Her continuing experimental garden demonstrates the value of keeping close records and verifying the rhythms through direct experience.

In “JPI Fall Intensive, 2012,” Porter follows preparation making from organs and plant material through stuffing, burial, recovery, and processing. Participants examined the rumen, reticulum, omasum, and abomasum; filled horns for BD 500; made Barrel Compound; filled skulls with oak bark; repaired and buried fifty yarrow-filled deer bladders; recovered chamomile, dandelion, and oak bark preparations; and practiced pest ashing. The report also records Hugh Courtney’s four-year BD 501 cycle: horn silica is lifted each fall, reburied the following spring, and processed after its fourth summer in the earth.

The Intensive makes the preparation system visible as a complete sequence rather than a collection of isolated materials. Participants worked directly with the BD 502–507 compost preparations, spray preparations, burial vessels, and recovery stages, while lectures connected the material work with the cow, constellations, and planting calendars. The combination of direct observation, repeated handling, and shared standards gives growers a dependable foundation for making and using preparations at home; JPI’s Making and Using Biodynamic Preparations guide provides a current practical companion.
