The Biodynamic Orchard Book by Ehrenfried Pfeiffer and Michael Maltas

This book brings together the best advice for cultivating fruit trees, berries, and shrubs, using biodynamic methods with the aim of harvesting healthy fruit free of pesticides.

Ehrenfried Pfeiffer, a pioneer of biodynamics in North America, discusses the principles of tree biology before describing the measures that can be taken to develop a pest-free orchard without the use of chemicals. He discusses soil preparation, the selection of trees for planting, issues of transplanting and pruning, the application of pastes, green cover crops, and pest control, before describing the key biodynamic preparations and how to spray them with greatest effectiveness.

Michael Maltas ran fruit tree experiments on his biodynamic farm in Missouri for four years. The results are recorded in a highly practical annual spraying schedule for orchards, which is reproduced in this book. A month-by-month calendar gives information on specific methods and controls, based on Maltas's extensive experience.
