Weeds & What They Tell Us, 3rd Edition

Ehrenfried E. Pfieffer


Weeds are weeds only from our human egotistical point of view, because they grow where we do not want them. In nature, however, they play an important and interesting role.? Thus begins this classic text written by a pioneer in the field of sustainable agriculture who, through his work with Rudolf Steiner and a lifetime of research, wielded a vast knowledge of plant and animal biology. This important book was written in the 1950s, yet no other book contains the overview that Dr. Pfeiffer presents here, and the message contained lives on as important now as it was over 40 years ago. Weeds and What They Tell Us, while somewhat dated and limited, is a classic that belongs on the bookshelf of every student of the soil.
