Join us for both indoor and outdoor learning sessions with Andrew Hillman of Davey Resource Group. Air-spading demonstrations and real-life examples. Andy's biography here.

If it was easy to grow healthy, thriving, beautiful trees in the built-up environment, everyone would be doing it! Abiotic stress often comes with the territory. Compacted soils, air pollution, salt runoff and spray, heat island effect, and more can compromise a tree’s ability to ward off biotic stressors like insects, fungi, and bacteria. Also, the trees we manage are usually the first to be threatened by a new pest or disease because the pathogens are often introduced through urban areas. In this session we will examine biotic and abiotic problems that affect our trees and explore ways and means to counteract them and help trees to not only survive, but also thrive.
