December 8 - Managing Edible Home Landscapes
Dr. Bernadine Strik, and Dr. Anita Azarenko, OSU Horticulture Dept.
Public attention on the economy and the environment has converged with a new interest in edible home landscapes. Many berry crops and fruit trees are excellent choices for the home landscape. This presentation will cover which berry crops and fruit trees are best suited, some cultivar choices, key management issues, and resources for more information.
December 15 - Pruning Young Trees and Shrubs for Structure and Form
Neil Bell, OSU Extension Service and Paul Ries, Oregon Department of Forestry
Plant a tree or shrub in a PNW landscape and it will probably survive. But if you want it to thrive instead of just survive, it is going to take some care – including early structural pruning. This session looks at identifying growth habit and flowering characteristics of trees and shrubs and using those to determine pruning requirements for best landscape looks and performance, and young plant pruning techniques that help prevent future problems.
The mission of the Pacific Northwest Chapter of the International Society of Arboriculture (PNW-ISA) is to foster a greater appreciation of trees and promote the professional practice of arboriculture through education, research, and technology. PNW-ISA is a 501(c)(3) nonprofit organization serving members in Alaska, Idaho, Oregon, Washington and British Columbia.
