Weeds and What They Tell Us
This wonderful little book covers everything you need to know about the types of plants known as weeds. Ehrenfried Pfeiffer discusses the different varieties of weeds, how they grow, and what they can tell us about soil health. The process of combating weeds is discussed in principle, as well as in practice, so that it can be applied to any situation.
First written in the 1950s, this is still one of the best overviews available on the subject.

About the Author
Dr. Ehrenfried E. Pfeiffer (1899–1961) was born in Munich. He worked closely with Rudolf Steiner to test and document many of the effects of biodynamic practices. Pfeiffer visited the U.S. several times during the 1930s, and was awarded a doctorate for his groundbreaking theory of Sensitive Crystallization Processes as a blood test for detecting cancer. In 1940, he immigrated to the U.S., where he pioneered biodynamic agriculture and helped establish the Biodynamic Farming & Gardening Association. He died in Spring Valley, New York.
