Soil Science for Gardeners

Soil is a living matrix of chemical and biological interactions, and a fundamental understanding of soil science is critical when selecting well-adapted native plants or choosing amendments needed by native plant communities. This two-day hybrid class for the ecologically-minded grower will discuss soil texture, chemistry, water-holding capacity, the biologically diverse life in the soil, and how these dynamic relationships can affect a plant’s health. Class Level: Intermediate

Horticultural Ecology

Plants interact with their garden environments, from abiotic influences like temperature, pH, humidity, and sunlight to biotic influences like other plants, animals, fungi, bacteria, and even humans. This two-day hybrid class teaches how plants adapt, compete, and depend on these influences. You'll learn concepts like parasitism, pollination, plant adaptation, and dispersal. Class Level: Intermediate to Advanced.

Landscaping for Wildlife

Habitat loss is the primary cause of declining wildlife populations, and learning how vital native plants are to wildlife and how much our landscape choices matter is one of the most critical steps we can take to divert such loss. Combined with a short online lecture followed by an interactive workshop and field study at the Gardens, students will learn how and what to manage in the landscape and how to incorporate certain native plants to create welcoming habitats that attract wildlife, conserve natural resources, and encourage biodiversity.

Selecting Native Woody Plants

Learn about native woody plants that contribute so much to our landscapes and local biodiversity in this two-day hybrid class. Andy Brand, Director of Horticulture at the Gardens, will discuss identification, habitat, and the role woody plants play in plant reproduction and management as hosts for insects, birds, and other wildlife. You'll leave with recommendations for native species and cultivars and guidance for cultivation, landscape uses, and soil and light considerations. Class Level: Intermediate-Advanced

Invasive Plants: Identification, Issues and Ecology

Invasive species are considered highly undesirable by botany, ecology, horticulture, and conservation professionals—and for good reason. In this three-part course, Amanda Devine, Regional Land Steward for Maine Coast Heritage Land Trust, will identify the basic ecological problems surrounding these aggressive, tenacious plants. We'll discuss the complicated, and sometimes political issues, and how a plant becomes labeled "invasive." Class Level: Intermediate-Advanced

Ecological Landscape Design

To design landscapes inspired by—and inclusive of—nature, it is essential to study design principles through the lens of natural systems. In this three-day course led by landscape architect Lisa Cowan and landscape designer and horticulturist Irene Barber, students will learn to identify and incorporate the components of ecological landscape design. Online and onsite, we will examine the systems influencing design decisions, practice environmental site analysis, and design conceptual plot plans for a selected site.
