Efficiency in Greenhouse Growing
This talk will cover the above-ground aspects of greenhouse production and how to make it more productive, efficient, and profitable. Jeff Marstaller, greenhouse grower and owner of solar-powered Cozy Acres in North Yarmouth, will share his experience and a variety operations factors to consider, such as location, resources, and business model. He will speak to a spectrum of subtopics including selection, timing and quantities of crops, potted plant production, processes, goals and expectations, and details of plant sales and distribution. Both the beginner and the experienced greenhouse grower will find a valuable chance to network and share knowledge among peers.
Too often, gardeners rush to buy seeds and seedlings before considering placement, growth habit, and time of harvest. In this class, Ellen Ecker Ogden, author of The New Heirloom Garden, will take you through the process of selecting and growing plants from seed, the reasons to procure seedlings, and where in a garden plants perform best to yield successful, tasty produce, easy growth, and beauty. Discussion will include best varieties for flavor, fragrant and edible flowers, growing in succession, saving your own seed for the following year, and much more. Ellen Ecker Ogden's book will be available for purchase on-site at the Gardenshop at Coastal Maine Botanical Gardens.
Most Maine gardeners and general property owners have had to deal with deer venturing out of the wild and into the cultivated landscape. Deer are part of the ecology in Maine, but an increase in their populations, coupled with displacement of their habitat, have caused them to become a nuisance animal in residential garden settings. In this online lecture, landscape designer Cheryl Salatino will discuss design strategies, plant selection, and other deer deterrent and management methods to prevent your plant investments from being grazed upon.
Learn the fundamentals of pruning in this online lecture and demonstration. Enjoy it as a refresher or, if new to it, gain the confidence to know what, how, and when to prune. Whether you’ve attempted to prune in the past with unsuccessful results, or you've been afraid to prune because you're not sure if you'll damage your plants, you’ll leave this lecture far more confident. We'll discuss appropriate tools, timing, goals, and techniques that will assist you in your pruning projects.
Perennial polycultures aim to grow useful plants together in a way that minimizes competition and maximizes cooperation. They include functional species to fix nitrogen, to serve as groundcover, and to attract pollinators and other beneficial insects. Perennial crops providing fruit, nuts, and vegetables anchor such designs. This workshop will review best practices for perennial polyculture design, introduce a palette of species suited to Maine, and allow participants to design sample polycultures.
In this online lecture, Shawn Jalbert, nurseryman and plant propagator at Native Haunts, will share the tricks to sowing, growing, and collecting the seeds of our native perennials, plants that thrive in woodlands or any shade-garden setting. He’ll discuss the ecologically responsible and effective ways to grow native plants from seed, resulting in a healthy, green living carpet that can operate as a long-term, cost-effective, and low-maintenance mulch.
Join us for a visually captivating virtual introduction to the life inhabiting CMBG’s wetlands. From inconspicuous invertebrates to loveable herptiles (i.e., amphibians), discover the diversity that flourishes in these wetland waters. CMBG's Bridget VerVaet will help students learn ways to find and identify these creatures during their own nature walks.
Join Alicia Miller, our Lepidoptera specialist, to learn more about some of Maine’s native butterfly and moth species. This virtual slideshow presentation will explore key identifying features of different Lepidoptera including morphology, adaptations, difference in range and habitat, and evolutionary history. We’ll discuss the importance of host and nectar plants and how you can help support Maine’s native species right in your own backyard.
Soil, compost, and mulches are fundamental elements for the garden, but it’s easy to become confused, overwhelmed, or unsure about what’s what. Mark Hutchinson, Soil and Compost Educator at the University of Maine Cooperative Extension, will discuss these elements, addressing in-ground and above-ground applications. Mark will provide an overview of proper selection of manufactured soil blends, mulches, and amendments and cover the basics of the soil chemistry and biology that determine the need for specified amendments.
In this webinar, Gary Fish, Maine’s State Horticulturist, will introduce and discuss common pests, including noxious to invasive insects, blights, rusts, diseases, and deficiencies. This class is geared toward those who aren’t necessarily scientists, but who thoroughly enjoy gardening and want to learn the symptoms and signs of infestation as well as prevention and management strategies. Students are welcome to e-mail pictures of specific plant concerns in advance of class to the class host, 
Get to know your backyard pollinators by exploring the diversity of northeastern bees. This virtual bees-and-beyond tour will teach you to recognize bees and distinguish one species from another. We will also explore their lifestyle, nesting habits, and the unique adaptations that make them nature’s best pollinators. Learn about bees’ relationships with plants, including the latest discoveries in plant-pollinator interactions.
Climate change is already impacting gardens, but how we garden can also impact climate change for good or for ill. We will look at projected changes to Maine’s climate and those gardening strategies we can employ to adapt to the new “normal.” We will also look at how to reduce greenhouse gas emissions from our gardens, from fertilizers to rototilling, and techniques to remove excess carbon dioxide from the atmosphere and store it in our soils and in living perennial biomass.
Ornamental grasses can add so much to a garden setting, whether in meadow restoration or to blend colors or add textural and structural accents to perennial gardens. Join Syretha Brooks, gardener and garden designer, for this interactive slideshow and learn more about the diverse selection of safe, non-native and native grasses to consider for your landscape. Syretha will offer management suggestions and habits for the species presented. Students also have the option to 
Prepare for a mindful gardening season by beginning or refreshing your understanding of horticulture. This introductory course will cover a wide variety of horticultural topics important for home gardeners to consider when growing and managing plants on any scale. Subjects will range from the theoretical to the practical, beginning with scientific foundations such as plant nomenclature, biology and ecology, pollination, and propagation. Other topics will include applied and artistic practices exploring plant selection, cultivation, and installation of new plants.
This session is cancelled.
Do you have a hard time identifying one variety of birch from another? Did you know we have five different species of birch growing in Maine? Join District Forester Allyssa Gregory in a field study tour of the Gardens’ trees, and learn more about forest culture and where to find common species growing in different regions of the state. Discussion will include identification of tree species during the growing and dormant seasons, distinguishing features of evergreen species, and the ecological and economical functions of our forests.
Witness the seasonal evolution of the Burpee Kitchen Garden. Filled with edibles and floral accents, the garden’s wares range from arugula to zinnia, itty-bitty seedlings to 12-foot stalks. Diane Walden, the Burpee Kitchen Garden’s designer and tender, will share her favorite garden occupants. In this unconventional kitchen/cutting garden, you'll discover new and unusual selections as well as the classics, whether planted in-ground or in containers, vertically trained with tuteurs.
There’s something powerful about herbs; whether it’s their scent, taste, or long therapeutic history, growing them successfully at home is especially fulfilling. Herbs also lend something special to any garden design, particularly curly parsley, sage, basil, and rosemary.
