Arboricultural Course Offerings at the Morris Arboretum of the University of Pennsylvania:

Introduction to Tree Biology
Thursday, May 13, 7 – 9 p.m.
Dave Tukey, Martha S. Miller Urban Forestry Intern, Morris Arboretum

The more we know about tree biology, the better we can care for trees including pruning, fertilizing, watering and protecting them from damage.  For each facet of tree biology such as hormones, defense against decay, soil relationships and branch attachments, we will explore ways to apply that knowledge to nurture both young and mature trees.  This information will be valuable for homeowners, gardeners, landscapers, tree tenders, members of shade tree commissions, arborists, and anyone curious to know more about how trees function.  This course carries 2 CEUs for ISA arborists. Morris Arboretum Members: $25; Non-members: $30

Soil Biology and its Effects on Tree Management
Monday May 10 9:00 a.m. – 4:00 p.m.
Dr. Joseph Heckman, Professor of Soil Science, Rutgers University
Dr. Jason Grabosky, Professor of Ecology, Evolution and Natural Resources, Rutgers University

This course will address the nature and composition of soils and how they impact the health and development of trees and shrubs.  We will examine the structural and chemical composition of soil as well as our historical understanding of it.  Most importantly we will examine the “living” component of soil, from microbes and earthworms to mycorrhiza and learn how the life below ground affects the growth of the trees above.  Students will receive a 48-page primer on soil biology as well as a compendium of relevant articles as part of the class fee.  This course carries 6 CEUs for ISA arborists and 6 CEUs for Pennsylvania landscape architects. Fee: $140 (includes lunch)
