Learn the why’s and how’s of pruning – why to prune, if you even need to prune, when to prune, and what cuts to make.  Wellesley College Botanic Gardens Senior Horticulturist Tricia Diggins teaches you to make cutting edge decisions about nearly every pruning job from house plants to large tres.  She explores with you how these general principles relate to specific plants like flowering shrubs, evergreens, older trees, young plants and fruit trees.  Approximately half the class time will be indoors and the remaiinder will be outside in the Hunnewell Arboretum and Alexandra Botanic Gardens, looking at the pruning needs of a variety of trees and shrubs.  The Wellesley College Hunnewell Arboretum can be damp under foot in early spring.  Please dress appropriately for the weather.  Class number HOR 10 080, WCFH members $20, non members $25.  To register, or for directions, log on to www.wellesley.edu/WCFH, or email horticulture@wellesley.edu.
