Six hundred homeowners, equally divided among rural, suburban, and urban areas in Minnesota responded to a 1999 phone survey on their lawn size, maintenance practices, and the perceived environmental impact of their lawns. The average lawn size was estimated to be 0.62 acres (0.25 ha), with an estimated 872,660 total acres (353,427 ha) in home lawns in Minnesota. Annual spending on lawn care per home was about $200, with an estimated $150 million spent annually in Minnesota. Participants reported low maintenance practices and pesticide use. A majority thought fertilizers and pesticides were harmful to the environment and public health. Respondents felt strongly that the government has a right to regulate fertilizers and pesticides in public park and lawn areas, but were divided with regard to the appropriateness of regulation on private property. Many (78.9%) disagreed or strongly disagreed with the statement that their lawn was harmful to the environment. Most (60%) felt their lawn could have an effect on the environment and 71% felt they personally could make a difference in the environment by how they maintained their lawn.

Master Gardeners (MGs) were paired with homeowners who volunteered their lawns for demonstration sites in Edina, Minn., as part of a yearlong community-wide campaign to teach low-input lawn care. Project objectives were to 1) promote locations where community members could see low-input lawn care, 2) provide individualized instruction to homeowners via MGs, and 3) explore the feasibility of home lawns as public demonstration sites. Surveys suggest that participants changed practices because of the individual instruction from MGs. Further recommendations are given for using private homes as demonstration sites.

Ultraviolet (UV) radiation poses a potential stress for plant growth and development due to its effect on photosynthesis and plant productivity. In the northern hemisphere, peak UV radiation exposure is predicted to occur from 2010 to 2020, with reduced color from UV-related injury, a possibility for turfgrasses. The objective of this study was to investigate the effects of ultraviolet-B (UV-B) light on turfgrass growth and morphology in three cool-season grasses. Cultivars Barvado tall fescue [Schedonorus arundinaceus (Schreb.) Dumort., nom. cons.], Penncross and L-93 creeping bentgrass (Agrostis stolonifera L.), and Barlenium perennial ryegrass (Lolium perenne L.), were selected because of limited information on their growth and development in elevated UV conditions at heights of cut above 10 cm. The impact of UV-B light treatment on color, relative growth rate, and tillering was measured over a 4-week period in repeated experiments. Ultraviolet-B radiation levels were measured at 16 kJ·m−2·d−1 biologically effective UV-B light in growth chambers programmed for a day/night regime of 14/10 hours. Chamber temperatures were maintained at 20 °C day/17 °C night. Ultraviolet-B light significantly inhibited tiller production in the first experiment in all grasses except PR, whereas no grasses were inhibited in the second experiment. Relative growth rates in all grasses were significantly lower in UV-B conditions 3 weeks after treatment initiation. Turfgrasses exposed to this level of UV-B light at typical lawn heights-of-cut had lower color ratings compared with the non-UV-B-treated control at 2 weeks after treatment initiation. The experiments demonstrated that exposure to UV-B resulted in a decline of growth rate and color in cool-season turfgrasses within a timeframe of 2 weeks. Coarse-textured turfgrasses [tall fescue (TF)/perennial ryegrass (PR)] may be more adapted to higher UV-B conditions due to morphological differences compared with the finer textured varieties [creeping bentgrass (CB)].
