This is a concise and practical guide to the biodynamic spray preparations. Based on a former pamphlet, now out of print, by Evelyn Spelden Gregg, this short text provides information to help the reader understand the sprays, as well as explanations of how to stir them, the water to use, containers and equipment, storage, amount and mode of application, horsetail tea, stinging nettle liquid manure, and tree paste. Clearly written, this classic text provides a good overview of the subject for the beginning biodynamic gardener or farmer.
