Urban trees are indispensable in making our cities livable. In the past 15 years, researchers in urban forestry have developed methods of quantifying the ecosystem benefits provided by urban trees. In our increasingly paved cities, tree services are essential, as it has become clear that poor practices in tree selection and soil preparation have reduced the potential benefits of planting such trees. As our metropolitan areas are so heterogeneous, not all trees will do well in all sites. However, the most ubiquitous constraint to healthy, urban tree growth is soil compaction and limited accessible soil volume, leading to stunted trees that cannot withstand increasingly hot and dry summers. Fortunately, there are many practices that can overcome these challenges.
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.
