Companion planting works - but only when you know why. This book is the result of 40 years of studying gardens, orchards and the bush; of Jackie French experimenting and testing what lore works and what doesn't. The results is a plan for gardens, that are unconventional and wild, untidy even, but always beautiful, without a need for pesticides and herbicides, where plants are companions for wach other and for the other species of the earth.
