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

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.

Introduction to Native Flora of Maine

The first step to gardening with Maine’s native plants is meeting them in their wild habitats. Over this three-day in-person class, Melissa Cullina, the Gardens’ Director of Plant Science & Collections, will help students recognize around fifty frequent coastal species. As a staff botanist, Melissa will cover plant identification skills, terminology, and botanical etymology. Through guided walks, both at the Gardens and a Boothbay Region Land Trust property, students will practice skills and collect samples for identification and botanizing native species.
