The Arboriculturalist's Companion: A Guide to the Care of Trees by N. D. G. James (Oxford University)
In addition the book covers such varying subjects as botanic gardens and arboreta, a summary of all the principal law cases which have been concerned with trees, arboricultural education and the choice of trees for urban areas. Intended for outdoor as well as indoor use, The Arboriculturalist's Companion is written in a concise and readable form and is a book that no one who is responsible for trees can afford to be without.
The second edition of The Arboriculturalist's Companion will be an indispensable reference for professional and weekend gardeners as well.
