Water Management in Urban Landscapes
Managing hydrology in cities presents profound design challenges including: finding space for daylighting and unsealing of pavement; managing urban flooding from extreme precipitation events; and restoring surface and subsurface water quality. These challenges are increasingly complex, given climate change and global urbanization. Landscape professionals have the skills and knowledge needed to meet these challenges while, at the same time, bringing beauty and resilience to our cities.
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.

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.

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.
