Books by Cass Turnbull

Cass Turnbull has been a professional gardener for 20 years. After seeing so many ruined trees and shrubs in her clients' gardens, she founded PlantAmnesty with the mission to teach gardeners (and so-called professional arborists) about the particulars of proper pruning. She has long been the humorous voice of PlantAmnesty through their regular newsletter. She lives in Seattle and lectures on pruning.
