From Nursery to Landscape: Tree & Shrub Selection

Longtime nursery grower Jeff O'Donal will discuss those often overlooked or forgotten factors that go into choosing trees and shrubs for a new landscape. While the setting itself dictates size and shape, also important to consider are tree health, the root-ball structure (whether in a pot or B&B), rate of growth, and adaptability to a new site. All this and more goes into choosing the right specimens for the right place, ensuring they thrive long into the future. Whether or not you’re a seasoned landscaper or gardener, this topic is always relevant to our practice. Come with questions and testimonials to share after the one-hour presentation.

Resilient Landscapes in Built Environments | Section I

Fridays, February 7, 14, 28, and March 7 | Resilient landscape practices are connected to the evolving environment. Incorporating low-maintenance design, resilient landscapes sustain and regenerate under stressful environmental conditions, rather than falling victim to stressors. They are aesthetic, powerhouse systems providing ecological services; as such, they give the landscape professional the opportunity to evolve their business, adapting to the changing environment. Section I of the course focuses on examining and incorporating ecological design and the influential components of water, soils, design lessons from nature, and sustainable structural materials.
