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. 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.
