Sustainable Horticultural Practices
Friday, June 16 & Saturday, June 24 | Ecosystem balance, soil, and water quality are all influenced by our landscape practices. This extensive, two-day sustainable horticulture class will help students apply the principles of ecologically safe gardening practices to their garden or landscape. Through online and in-person sessions, we’ll examine composting, techniques for eco-friendly soil amendments, alternatives to pesticide and herbicides, responsible native plant acquisition, erosion control methods, plant forms for function, and so much more.
Color, color, and more color! Join us and learn how visually stunning color combinations can be achieved effectively and harmoniously in container garden design. Sometimes too much color can be overpowering, but color can be expressed in many ways—through hue, tone, shape, and texture, creating wide-ranging visual appeal. Join Brent McHale, container-garden designer and Gardens Horticulturist, to learn how to create your own colorful container garden, one that achieves its effect through flowers, foliage, and seasonal succession. All planting materials will be supplied by the Gardens. The instructor will contact you to ask if you want a shade- or sun-loving plant selection. Please bring your own garden gloves and clippers.
Water-wise gardening is another way of referring to designing with water in mind, especially relevant to drought conditions. Water-wise container gardens lend themselves to an exotic and creative assortment of annuals or perennials like succulents, alpines, and plants with fuzzy leaves, leathery-glossy leaves, or those with varied color- and textural characteristics. Join Gardens Horticulturist Jen Dunlap for this creative workshop and make your own drought-tolerant container garden. Students are encouraged to bring their own clippers, apron, and garden gloves. While this class is a part of our adult education offerings, it is open to advanced younger students, ages 14 and older.
Weeds, by casual definition, are undesired plants found in a certain location. In this class, we will discuss the perception of weeds as well as their identification, cultural management, and ecology. Learning the identity of a “weed” may change the desire to remove it from the landscape as you realize its potential benefits. While sometimes weeds are just misunderstood plants, there are times they can be invasive or toxic, so it is important to properly identify and learn how to manage for these species. Join Delany Pitman, CMBG Horticulturist, in this mixed field-study and lecture class and broaden your awareness of why, what, when, how, and where these plants live and if they can be embraced or must be eradicated from a garden or landscape.
Water gardens are growing in popularity for a number of reasons: to attract wildlife like birds and butterflies, to add a melodic sound feature, to contribute light reflection, to offer a place for personal respite, and to cool down a garden space. Water gardens that incorporate unique and lush plants add bold shapes, forms, colors, defined lines, and textures to a garden space. In class, students will make and take home a small water garden container filled with personally selected plants supplied by the Gardens. We'll talk about the wide variety of plant options, materials, and different kinds of water garden designs. While this class is a part of our adult education offerings, it is open to advanced younger students, ages 14 and older.
Ever wondered what wildlife is living in your backyard? In our seasonal series of field-study classes (register separately for each), participants will learn more about the creatures that live in or around their garden, looking for shelter, food, and water. Join us and see summer animalactivity first-hand, an experience that will provide deeper insight into and appreciation for their roles in the ecosystem, better informing us how humans and wildlife can live together more harmoniously. This month, we’ll primarily focus on the diverse world insects, especially pollinators and beneficials, then learn about the mammals that are feeding and starting their families during these lazy days of summer.
Have you been gardening with hydrangeas and experienced challenges with blossom performance? Are you wondering what kind of hydrangea you have? Join Horticulturist Courtney Locke to learn more about gardening with hydrangeas in Maine, including best selection, cultivation, and care. Tour the Gardens and see the diverse display of our different hydrangea species and cultivars, and learn firsthand what environmental conditions are needed to successfully grow certain species and varieties.
Ever wondered what wildlife is living in your backyard? In our seasonal series of field-study classes (register separately for each), participants will learn more about the creatures that live in or around their garden, looking for shelter, food, and water. Join us and see autumn animal activity first-hand, an experience that will provide deeper insight into and appreciation for their roles in the ecosystem, better informing us how humans and wildlife can live together more harmoniously. This month, we’ll discuss preparing your garden for winter while also supporting the wildlife that migrates or overwinters locally. We’ll primarily focus on the ways birds, mammals, and insects are starting to prepare for winter.
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.

Perhaps you love to cut and arrange flowers from your garden, but have you considered growing them from seed? In this class, you'll learn how to grow your favorites and new varieties from seed, including annuals, biennials, and perennials, from cut-flower grower and aficionado, Courtney Locke. As the grower, you'll get to nurture and manage the quality of your plants and save money. Plants grown from seed acclimate to your garden better than those grown elsewhere. 
Staff horticulturists Jen Dunlap, Catherine Kaczor, and Lon Ames share their top 20 plants for erosion control in this online panel discussion. While these plants can be functional to support our soils, they are beautiful and can be utilized in combinations as ornamental as any traditional garden. Learn about the various heights, habits, and ideal environments. 
Viburnums are an important genus in New England landscapes, offering essential habitats for wildlife and attractive seasonal floral and berry displays. Join Lon Ames, horticulturist for the Haney Hillside Garden, in his online class to learn about native and non-native viburnums that can be used in your garden borders. Discussion will include sizes, habits, ecological benefits, and characteristics that make viburnums stand out in your displays.
