Tree Pests: The Future of Tree Selection and Resilience

Trees, whether forest or cultivated species, are experiencing major pest problems, most of which have been brought about by human impact. We’re now left wondering what will happen to Maine's forests and what the impact to our landscape will be. Will there be economic implications? Will some species show more resistance and resilience than others? Will pest species’ life cycles persist or lessen over time? How will these pests impact Maine's nursery and landscaping industry? Allison Kanoti, State Entomologist for the Maine Department of Forestry, will dig into these questions and more, offering clarity that will help us become better prepared and informed.

Garden Design: Structure and Movement

Once we have the conceptual ideas narrowed down to one or two general schematics of our garden spaces, we can start shaping them with program and structure. Structure and movement consist of more than a row of shrubs, a fence, a path or a wall at your property line – this is how you shape a space, create a sense of enclosure, and lead the eye to landscape destinations. This online lecture and demonstration will identify features and design principles captured initially on trace layers, which will ensure both pragmatic and inspirational function in our gardens. After this class, students will feel empowered to practice on the personal project that will help them prepare for the next class, Garden Design: Details in the Layers. Upon registration, students will receive a list of supplies recommended to pursue their own design project.

Plants for Pollinators: Who are They?

Interested in learning about plants for pollinators? Want to understand why some plants attract pollinators better than others? For centuries, passionate plantspeople have collected plants from the wild, hoping to enhance floral or foliar displays or increase resistance to disease or pests. But where wildlife is concerned, beauty is definitely in the eye of the beholder. Join us to learn from our pollinators and see what plants they choose. Join staff Entomologist Zac Smith-Hess to hear what the evolving research says about the ecological evaluation of native straight species, cultivars or non-native plants in built landscapes. We’ll talk about genetic diversity, clonal cultivation, pollinator syndromes, and their role in insect visitation and health.

Zac Smith-Hess’ passion for exploring and connecting people to nature has led him into both formal and informal education. Since graduating with a degree in zoology in 2014, he has spent much of his career working specifically with invertebrates in zoo and classroom settings. His students have called him a true lifelong learner; you can see this when you find him on grounds of the Gardens, providing wandering interpretation or, as he likes to say, just talking about bugs.
