Lawns

Traditional lawn care for suburban American households merits examination from both ecological and social perspectives. Such practices have potentially detrimental consequences on human and natural systems that will continue to grow with urbanization. Consequently, further characterization of the complex, multiscale processes in which lawn management decisions are rooted could enhance methods for encouraging the adoption of alternatives to industrialized lawn care. This study conceptualizes mesoscale, or neighborhood-level, influences on watering, fertilizing, and mowing practices in Baltimore city, through a modified grounded theory analysis of key informant interviews in Mount Washington, Westfield, and Park Circle. This study finds that mesoscale processes play a significant role in the residential lawn care of these neighborhoods. The applicable processes vary by the community’s social cohesion and tenets. As socioeconomic status and social cohesion increases within the study area, the influence of informal authority in residential lawn care increases. Results demonstrate potential policy implications.

Water conservation initiatives seldom quantify the volume of water that is at stake in lawn watering. In many communities, including those in South Florida, outdoor water use, which includes lawn irrigation, is not metered separately from indoor water use and is indistinguishable from indoor water usage. A large number of residents use self supply non-potable wells for lawn irrigation that are not regulated by the South Florida Water Management District. The result is that residential lawn water use is difficult to account for and quantify. This thesis project addressed these difficulties by combining semistructured interviews, daily watering observations and irrigation system audits to ascertain how much public supply water and self supply (well) water was being used for residential lawn irrigation. The study also examined lawn watering practices and how factors such as: precipitation, the minimum plant needs of St. Augstinegrass, and how local watering restrictions influenced watering behavior.
