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.

Landscaping with Wild Edibles

Growing edibles, especially natives, is a practice gaining traction in New England’s landscape industry. Incorporating native and wild edible plants provides a number of benefits; it adds biodiversity to the landscape, and eating produce straight from the garden deepens a connection to nature. Andy Brand, the Gardens’ Curator of Living Collections, will discuss some of his favorite perennial native edibles, from the woody to the herbaceous, highlighting design applications for both function and beauty.

Foundational Factors for Sustainable Turf

A sustainable and ecologically sound turf system succeeds when it is built on a foundation of sound agronomic practices matched to site characteristics and turf performance objectives. We will consider how factors such as aspect, light, soil condition and health, proximity to environmentally sensitive areas, and degree of turf maturity can inform decisions regarding implementation and timing of key cultural practices. In particular, we will examine the selection and establishment of appropriate turfgrass species and cultivars as an essential component of turf sustainability.

Establishing Trees in the Urban Landscape

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.

Landscaping with Deer

Most Maine gardeners and general property owners have had to deal with deer venturing out of the wild and into the cultivated landscape.
