Issue 027 presents JPI’s growing institutional capacity and the first installment of Hugh J. Courtney’s practical series on weed ashing, or biodynamic “peppering,” with BD 508 horsetail as a preparatory soil treatment.
“Biodynamics Under Attack?” records JPI’s defense of the long-used term “BD Preps” as shared biodynamic language when another party sought a private trademark. JPI, the Biodynamic Farming and Gardening Association, and Demeter submitted objections through the U.S. Patent and Trademark Office.
The editorial also documents strong forward movement. A $60,000 Rudolf Steiner Foundation loan helped complete JPI’s new building, fund about $8,000 in computer equipment, and support more than $10,000 in preparation inventory. JPI received its occupancy permit on February 2, 2000, welcomed new staff, and continued preparation work, seminars, research, and education.
Hugh J. Courtney’s “Ashing or BD ‘Peppering’—A Function of Lunar Forces” describes species-specific weed peppers made from the target weed’s reproductive material—usually seed, or a rhizome for a spreading perennial. The issue records several established methods, including complete ash, char, gentle toast, and wet putrefaction.
For the ripe-seed ash method, collect fully mature seed of the identified target weed, burn it completely, then grind or rub the ash with clean soil or sand and scatter the mixture over the target ground. Courtney describes JPI’s fire-platform method using hardwood charcoal and a slow burn through the blue-flame stage before the cooled seed and wood ash are collected.
The article cites Lilly Kolisko’s thistle work as a positive multi-year result. Thistles still grew after two annual treatments, but their seeds began to deteriorate; in the third year the thistles were very scarce; and after four years of repeated treatment they disappeared completely from the treated area. The account identifies seed deterioration as the first visible stage of the process.
Courtney gives BD 508 horsetail a foundational role before species-specific peppering. He presents horsetail tea sprayed on the soil as a way to moderate the strong lunar and moisture conditions associated with weed reproduction, preparing the ground for the subsequent ash treatment.
Maria Thun’s timing guidance links each weed with the lunar constellation under which it germinates most strongly and calls for annual repetition over a four-year cycle. The series continues in Issue 028 with further dilution and application detail.

Repeatable Practice
- Identify the target weed and collect fully ripe reproductive material, keeping each species and batch distinct.
- Choose the issue’s complete-ash, char, gentle-toast, or wet-putrefaction method and record the method used.
- For the ripe-seed ash method, burn the seed completely, grind or rub the ash with clean soil or sand, and distribute the mixture over the target area.
- Apply the species-specific timing described in the issue and repeat the annual treatment through the multi-year cycle.
