Advanced Pruning with Cass Turnbull
Cass Turnbull is an internationally recognized authority on pruning. She is the founder of Plant Amnesty. Her presentation will cover the three main forms of mal-pruning: tree topping, inappropriate shearing of trees and shrubs, and over-thinning. This is an advanced course and those attending should be familiar with principles of selective pruning. Included is discussion of water-sprouts, suckers, radical renovation techniques, and crown restoration. The class ends with an outdoor show and tell, live evaluation and pruning demo.
