This book is best for people with already a few months experience in Arboriculture. It gives good explanations on industry standards and how training Landscape Tree's can be obtained from Nursery to the Customer's Property, alongside with mistakes you can avoid that you see common in the industry.
The only reason I say it is best for those with a few months experience because there is a lot of information you probably want some vague background knowledge on to fully be able to understand and comprehend it all.
This book isn't too forthcoming in knowledge for Certified Arborists who already know about Branch Protection Zones, Codominant Stems, Training Leaders, and so on.
I would recommend this to anyone looking to become an Arborist or more familiar with how Trees are pruned, grown and taken care of throughout their years.
