As warm temperatures and longer days drive an abundance of growth, the Burpee Kitchen Garden series will focus on how to grow warm-season greens, herbs, flowers, and vegetables. Diane will elaborate on practices such as weeding, successional cropping, and harvesting, all while highlighting her favorites, alliums and basil.

In this outdoor class, permaculture landscaper Justin Nichols will offer a new perspective on common weeds. Illustrating that truly “one person’s trash is another’s treasure,” many consider weeds valuable medicinal, edible, and ecological plants that can tell a story about surrounding soil conditions. Of course, there are also those that can be a nuisance. In this class, Justin will share weed-related wisdom, guiding participants in identifying, recognizing, and then approaching these gardening questions—nuisance or nutrient?—from a more informed perspective.

Justin Nichols has been enthusiastically maintaining landscapes since 1989, including many years as a gardener on a 30-acre estate in the Boston area and six years here at CMBG on the horticulture staff. He currently runs an ecologically-focused landscape and design business based in the Portland area. He is a NOFA Certified Organic Landcare Professional, holds a master’s degree in education and enjoys teaching horticultural topics to people of all ages.

In this class, Courtney Locke, bulb grower and Staff Horticulturist, will discuss the world of bulbs beyond tulips and daffodils. Although the latter are beautiful and deserve attention, there are many varieties that bloom later into the summer and fall. Aconites, Camassia, and fall crocus are just a few that will be featured. Courtney will take you on an online visual journey; learn how to landscape with these bulbs, including naturalizing or gardening within an ornamental border, and how to manage bulb species over time—most bulbs are perennials, perfect partners in sustainable gardening.

Whether grown from seed or transplanted as seedlings, native woody species can adapt to changing conditions and challenging environments, benefitting urban communities and rural developments or woodlots by filling in empty spaces and protecting and bringing nutrients back to the soil.

Join dahlia lover and horticulturist Courtney Locke to learn the best methods for growing these stunning gems. We’ll cover all aspects of locating, planting, and growing dahlia tubers, including purchasing, site planning, soil preparation, staking, feeding, pest protection, and (finally!) cutting and enjoying these sumptuous flowers. Learn how to identify the parts of a tuber, the different types of dahlia flower forms, and determine the best fit for your garden. As CMBG’s official dahlia grower, Courtney knows first-hand the exceptional cultivars that produce the jaw-dropping blooms that are truly worth the wait.

In this panel presentation, four CMBG horticulturists will review their top five perennials, from longtime favorites to new darlings from the 2021 growing season. With so many beautiful perennials at CMBG, each showing off unique foliage, flowers, structure, and wildlife benefits at various times of the year, it’s difficult to choose which ones to feature—but these top-20 are a good place to start!

Choosing native plants for your landscape should be fun and creative, not daunting or complicated! When you consider plants in simple groupings, or guilds, it becomes a lot easier to design a landscape with appealing texture, color, and wildlife value throughout the seasons. Native plant guilds draw inspiration from naturally occurring plant communities in habitats like coastal plains, forests, wetlands, or mountain tops. Leave this introductory webinar inspired, with plant lists for various light and soil conditions or landscape functions and the tools necessary for selecting your own plants for beauty and biodiversity.

Whether designing one garden or several, the first step is to understand the history and significance of garden design before diving into its fundamentals. Irene Barber, landscape designer and the Gardens’ Adult Education Program Manager, will introduce students to garden themes from different cultures and civilizations, all of which relate to the principles and elements of design relevant today.

Geography and cultural history are pertinent factors for decisions made in garden design, particularly in New England’s unique and diverse landscapes, from river valleys to rolling fields to narrow, rocky corridors. Students will understand how to establish a sense of place and belonging, wherever their prospective garden is to be located. No matter what cultural elements and influences you want to incorporate, this class will help you get creative while staying true to a sense of place.

Whether as a refresher or a first foray into pruning, students gain confidence in this workshop and demonstration covering pruning fundamentals. Learn to know what, how, and when to prune, even if you’ve attempted it in the past with unsuccessful results, or you've been too afraid to try for fear of damaging your plants. We'll discuss appropriate tools, timing, goals, and techniques to assist you in your dormant pruning projects. Demonstrations will include fruit trees, berry bushes, some semi-herbaceous, and cover the timing for shrubs such as lilacs, rhododendron, and more.

Please note this class requires participants to show proof of having received all eligible Covid-19 vaccinations, as recommended for their age by the CDC, in order to participate. Because of the dynamic nature of this situation, we ask that you agree to abide by potential future changes in CMBG’s Covid-19 policy designed to address evolving public health recommendations.

Beginning a base plan for a plan-view design of your garden may not be the most exciting part of the process, but it is an all-important one! Join us as we discuss everything from how and what to measure for a new garden to translating that information into a scaled drawing on paper. Once a base plan is established, the designer can get creative, tracing over it until they are happy with (and excited about!) their design, the topic of discussion in the next class: Dreams to Design. Students will be responsible for their own design materials, supply list available upon registration.

In this panel presentation, four CMBG horticulturists will review their top five annuals, from longtime favorites to new darlings from the 2021 growing season. With so many beautiful annuals at CMBG, each showing off unique foliage, flowers, and structure, it’s difficult to choose which ones to feature—but these top-20 are a good place to start!

Tuesdays, March 22 and 29 | Countless new terms and often-conflicting advice can make gardening intimidating, not only for newcomers, but also for those who have been gardening for years. In this course, we’ll set gardeners up for success in the potentially overwhelming world of horticulture. Using practical, real-life examples and engaging activities, we'll review how plants are named and classified, basic plant anatomy, and how environmental factors can influence plant growth.

Soils, mulches, and amendments are fundamental for growing plants successfully indoors or out, but it’s easy to become confused, overwhelmed, or unsure. In this webinar, we’ll review what’s what, addressing in-ground and above-ground applications pertinent to vegetable, woodland, or container gardens. We’ll also discuss the variety of manufactured soil and soilless blends, mulches, amendments like composts and mineral additives, the basics of the soil chemistry and biology, and making sustainable choices.

Whether designing a secret garden or an extensive wildflower garden, it’s critical to run an assessment of the setting—built features, where water flows, and how much sun hits the area between growing months. We'll discuss what a site assessment and inventory looks like and how sketching this information gives designers a visual diagram, providing a clearer understanding of any variables to consider. The more informed you are as a designer, the better a designer you’ll be! Students will be responsible for their own design materials, supply list available upon registration.

Orchids are amazing plants—and an engrossing indoor hobby for us northern gardeners. In this fun and enlightening class, learn from CMBG horticulturist Courtney Locke how to successfully grow orchids year-round as houseplants. With so much advice out there, it’s inevitable that confusion would arise. Learn from a true orchid grower and enthusiast, and soon you’ll be on your way to nurturing these intoxicating plants in a variety of arranged containers.

When designing a new garden, it’s tempting to dive right in and start selecting plants – it’s what we plant nerds love best! But we’re doing more than creating a space to show off favorite flowers—we’re creating one that also incorporates and considers circulation, function, character, and scale. Join us as we train our brains and sketching hands, learning how to use graphic and conceptual tools to think bigger about the possibilities of place-making.

From gardening to landscape projects, the right tool makes the process easier, less strenuous, and more efficient. A chef wouldn’t use a butter knife to slice a roast, and a carpenter wouldn’t secure an inch-thick board with a half-inch nail! In this behind-the-scenes look at the CMBG horticulture staff's favorite tools, you'll learn why certain tools are appropriate for certain jobs. We’ll also discuss the more effective and ergonomic options out there—it might be time to replace that splintering, 30-year-old spade you're still using!

Once we’ve got the bigger picture of our garden spaces in mind, we can start shaping them with program and structure. In garden design, structure is more than a row of shrubs, a fence, or a wall at your property line – it’s how you shape a space, create a sense of enclosure, and lead the eye to landscape destinations.

In this session, we’ll look at palette and plant choices, focusing on personal and environmental considerations, and take our design dreams and translate them onto paper. Utilizing the base plans created in an earlier session, we’ll look at the current garden space, visualize what we want it to become, and articulate that onto paper in several conceptual drafts.

Whether you're working on a new garden design or revising an existing space, this final installment of our garden design series will address both the large-scale process and the detailed specifics of your personal design. We’ll work together in a collaborative workshop, presenting and providing constructive feedback on students' unique design efforts.
