Cooperative Extension has a long history of using radio broadcasts in educational programming. The Minneapolis, MN-based CBS affiliate WCCO Radio 830AM contacted the University of Minnesota Extension (UMNExt) in 2013 to reinstate an 8:00 AM Saturday live gardening show titled “Smart Garden”. After several years of doing the radio show, we wanted to determine the effectiveness of getting information to listeners, what people were doing differently because of what they heard on the show, and how much they used the Extension’s resources after listening to the program. After analyzing 410 responses to an online survey, we found 78% of respondents reported they frequently or always learned something new when listening, and 56% reported adopting environmentally important practices, such as pollinator gardens, less chemical use, better lawn care, water conservation, and removing invasive plants. We concluded that this educational programming was making a positive impact on consumer horticulture practices. [ABSTRACT FROM AUTHOR]

Native grasses act as host plants, providing food and shelter, for numerous Lepidoptera species during their larval stage. As grassland habitat decreases because of conversion to agriculture and urban areas, prairie specialist butterflies and moths have also declined. Addition of native species to urban and agriculture landscapes has been shown to benefit Lepidoptera communities in various ways. Native grasses have grown in popularity as a landscaping plant due to their low nutrient requirements, drought tolerance, and soil stabilization properties. However, the benefits of native grasses to Lepidoptera are not well known to many entomologists or horticulturists, let alone the average consumer. We reviewed the literature that identified native prairie graminoids as host plants for native Lepidoptera in Minnesota, especially plants widely available in the horticultural trade that could be planted for restoration or landscaping purposes. The context of the Lepidoptera and host plant associations found in the literature are described. In total, we found 36 Lepidoptera species that used 17 prairie graminoids as host plants cited in the literature. Three native grasses, Schizachyrium scoparium (Michx.) Nash, Andropogon gerardii Vitman and Panicum virgatum L. and were found to be used by the most Lepidoptera species, 11, 9, and 8, respectively. Most likely there are additional moth species that use these grasses as host plants because butterfly species tend to be better documented than moth species. The specific larval habits and host plant species were unknown for many species of moths that feed or are suspected to feed on graminoids, showing the need for further research in this area. This information can assist horticulturalists, ecologists, landscape planners, land managers, and homeowners in their decisions to buy and plant native grass species. In general, this knowledge provides increased awareness about the larval life stage of butterflies and moths to concerned citizens and green industry and further supports the importance of conserving native prairie to support and maintain Lepidoptera species.

Landscape plant evaluations were conducted in eight states: Colorado, Minnesota, North Carolina, Ohio, Oregon, Pennsylvania, Texas, and Vermont for 17 switchgrass (Panicum virgatum) and five little bluestem (Schizachyrium scoparium) cultivars. Additional locations in Florida (Fort Lauderdale, Fort Pierce, Quincy, and Wimauma), Nebraska (Lincoln), and Lubbock and San Marcos completed 1 or 2 years of the trials. Plants were established in 2012 and data were collected for 3 years, 2013-15. Sites were asked to compile annual data on plant height, width, flowering time, fall color, pests, foliage color determined by the Royal Horticultural Society's color chart, plant form, flowering date, floral impact, self-seeding, winter injury, landscape impact, and mortality. Texas A&M Agricultural Research and Extension Center (Overton), Florida (all four locations), and Vermont had the highest mortality rate. Southern Florida locations lost 50% of their plants by the end of 2014. Wide variation was reported for landscape impact, individual cultivar height, and width from different regions of the United States. Three of the 17 switchgrass cultivars, Cloud 9, Northwind, and Thundercloud, had a rating of 4.0 or higher averaged over six or more locations for plant form, floral, and landscape impact. 'Shenandoah' and 'Warrior' switchgrass had a rating of 4.0 or higher averaged over six or more locations for plant form and landscape impact, but not floral impact. Only one of the five little bluestem cultivars, Blue Heaven® rated 4.0 or higher, for plant form and landscape impact when averaged over six or more locations. This range of variability in landscape plant performance demonstrates the importance of local plant evaluations. [ABSTRACT FROM AUTHOR]

Based on a survey of the American Society for Horticultural Science (ASHS), membership need was identified for an online peer review system to validate innovation and recognize excellence in science-based teaching and extension scholarship for promotion and tenure purposes. This system would also provide a clearinghouse for instructional materials of merit for use in classrooms, laboratories and outreach education, which fall outside the parameters of die three academic journals of ASHS. It was determined HortTechnology already provided a valued outlet for peer review of manuscript style teaching and extension scholarship; however, a need was identified for a mechanism to provide peer review of instructional materials which did not conform to a traditional manuscript format. Herein we describe the process that led to the development and launch of HortIM™, a new peer review system for teaching and extension instructional materials. An online peer review process for juried assessment of instructional materials such as articles, bulletins, case studies, fact sheets, instructional videos, teaching modules and laboratory exercises was developed. A beta test of initial solicited materials in each category was piloted resulting in an initial database of these scholarly materials. This activity culminated in an initial opening of the system for submissions in Fall 2016. This article documents the development of HortIM™, including the submission and review process.

The floral industry has experienced declining sales in the past few decades, causing many to speculate as to the underlying causes. To identify consumers' spending patterns for fresh flowers and potted plants, we extracted and analyzed quarterly expenditure interview data from the C onsumer Expenditure Survey, 1996 to 2013. O ur analysis revealed consumption trends over time by age group, and compared the differences in expenditure patterns across states. Additionally, we employed the Heckman two-step model to estimate how flower consumption is affected by sociodemographic characteristics, geographic factors, housing status, and seasonal factors. The estimation results show that the source of declining demand can be attributed to the decrease in both number of flower purchasers and expenditure among purchasers. Many factors including age, marital status, gender, education, income, number of earners in household, population size of the residing city, house type, and number of rooms in the house affect the demand for fresh flowers and potted plants. Given that floral expenditure has been decreasing among consumers under 40 years of age for the past two decades, innovative m arketing strategies to target this age cohort are essential for the floral industry's success in the future.

Consumer horticulture encompasses a wide array of activities that are practiced by and of interest to the gardening public, garden-focused nongovernmental organizations, and gardening-related industries. In a previous publication, we described the current lack of funding for research, extension, and education in consumer horticulture and outlined the need for a strategic plan. Here, we describe our process and progress in crafting a plan to guide university efforts in consumer horticulture, and to unite these efforts w ith stakeholders' goals. In 2015, a steering committee developed a first draft of a plan, including a mission statement, aspirational vision, core values, goals, and objectives. This draft was subsequently presented to and vetted by stakeholders at the 2015 American Society for Horticultural Science Consumer Horticulture and Master Gardeners (CHMG) working group workshop, a 2015 Extension Master Gardener Coordinators' webinar, and a 2015 meeting in Washington, DC. Feedback received from these events is being used to refine and focus plan goals and objectives. The most recent working draft of the plan can be fomid on the website, where stakeholders and other interested parties can register to receive updates and to provide input into the process.

The American Society for Horticultural Science (Alexandria, VA) and Longwood Gardens (Kennett Square, PA) engaged FleishmanHillard (FH, Washington, DC), a nationally recognized communications and marketing firm, to conduct research with internal and external audiences to determine the public perception of horticulture and careers in horticulture. Through stakeholder focus groups and general public online and phone surveys, the importance of horticulture, career perceptions, and the need for the promotion of horticulture were examined. Students, faculty, industry, and administrators in horticulture have a broad understanding of the field, much more than the public, especially young, ethnically diverse, and lower income participants. Although lack of public awareness is one of the biggest challenges in horticulture, it is also its greatest opportunity. Sixty-five percent of all phone survey participants as compared with 41% of 18-24 years old revealed a general awareness of the word horticulture. General public found agreement (48% to 59%) with four statements about the essential, universal, and invaluable worth of horticulture; however, strong agreement was less, ranging from 26% to 46%.Only 26% of respondents felt strong agreement with the statement, "Horticulture is a diverse area of study, and it offers viable, fulfilling, and respected career paths that I would recommend to others." The research found strong stakeholder support for a national promotion of horticulture. [ABSTRACT FROM AUTHOR]

The commercial potential of genetically engineered (GE) crops has not been fully realized in the United States. Over the past decade, environmental litigation dramatically affected the pace of GE crop development, testing, and deregulation. The U.S. Animal and Plant Health Inspection Service (APHIS) regulates GE organisms that may pose a risk to plant or animal health. However, recent litigation initiated by nongovernmental organizations such as the Center for Food Safety and the International Center for Technology Assessment has exposed APHIS's vulnerability to lawsuits under the National Environmental Policy Act (NEPA) for failing to assess the environmental risks of novel GE crops. In these cases, APHIS committed two types of mistakes. First, APHIS did not differentiate between traditional GE crops whose risks are well characterized and novel GE crops that may raise unique environmental risks and societal issues based on their distinctive biology. Consequently, it did not adequately evaluate the legally defined environmental risks of these novel crops. Second, APHIS did not fully appreciate NEPA's sweeping scope and focus on procedural compliance to ensure transparent and thorough environmental decision making. As a result, APHIS impeded the development and commercialization of GE crops and must take a more defensive posture in the future to deter costly and lengthy NEPA litigation in the case of novel GE crops.

Pennsylvania sedge (Carex pensylvanica) is an upland forest sedge with restoration and horticultural potential as a low-maintenance groundcover for dry shade. For large landscape and restoration plantings, seed or achenes in this case are much preferred due to lower labor and material costs. However, Pennsylvania sedge typically produces few achenes in its native habitat. As a first step in improving achene production, this research evaluated the effect of vernalization and photoperiod on floral initiation and development. We conclude that this sedge is an obligate short-day plant that does not require vernalization for flowering. Plants flowered when exposed to daylengths of 6 to 12 hours. Flowering was completely inhibited with 14-hour photoperiods. Pennsylvania sedge was florally determined after 4 weeks of 8-hour photoperiods. Inflorescence quantity and normal floral development varied by clone and by weeks of exposure to 8-hour photoperiods. For two of the clones, the largest number of normal monoecious inflorescences was produced with 8 to 10 weeks of 8-hour photoperiods while the other two clones only required 6 to 8 weeks of exposure to inductive photoperiods. Therefore, it is important to evaluate observable variation between clones when attempting to propagate Pennsylvania sedge. [ABSTRACT FROM AUTHOR]

An online survey of readers of the University of Minnesota Extension's electronic Yard & Garden Newsletter (Y&G News) revealed significant differences between respondents on the basis of current employment and Master Gardener affiliation. Fifty-three percent of the respondents were general public (GP); 31% were Master Gardener trained (MGT), followed by full-time horticultural employees (FTE) and part time horticultural employees (PTE) , each of whom made up to 8% of the 500 readers who responded to the survey. Overall, respondents indicated a high level of satisfaction with the newsletter (4.8 out of 5.0), and 81% indicated that the newsletter had provided them with "specific information that they found extremely valuable" in the past 2 years. PTE and MGT respondents rated the newsletter as significantly more useful than did the GP. FTE placed greatest value on timely information related to pest control. GP subscribers indicated that annuals and perennials were the horticultural topics they were most interested in for future issues. All subscribers highly value the newsletter for its usefulness and timeliness and indicated that the newsletter improved their ability to make horticultural decisions. Ninety-nine percent would recommend the newsletter to a friend. The mission of the Y&G News and content changes based on survey responses and available resources are discussed. [ABSTRACT FROM AUTHOR]

Pennsylvania sedge (Carex pensylvanica) has horticultural and restoration potential, but the achenes are difficult to germinate due to complex dormancy requirements. This study identified treatments to overcome physiological dormancy and determined light and temperature requirements for optimum germination. We first tested the effects of perigynia removal and light on achene germination. In the second experiment, achenes were subjected to varying durations of dry-cold or dry-warm storage conditions and a presowing soak in gibberellic acid (GA
3 ). In a third experiment, we studied whether storage conditions, cold stratification, and sowing temperatures affected germination. Pennsylvania sedge germination was improved by dry-warm storage, perigynia removal, cold stratification, and germination in light. [ABSTRACT FROM AUTHOR]- Published

The North Central Consumer Horticulture Working Group developed and distributed a 14-question survey to determine the confidence of north-central U.S. extension Master Gardeners (MGs) in making integrated pest management (IPM) recommendations and their use of IPM. The online survey was completed by 3842 MGs in Illinois, Indiana, Kansas, Michigan, Minnesota, Missouri, Nebraska, North Dakota, Ohio, South Dakota, and Wisconsin. MGs indicated they personally engaged in a range of IPM practices, including prevention, monitoring, cultural, and chemical controls. However, 81% indicated at need for more training in identifying diseases, and 65% say they needed more training in identifying insects. Only 16% indicated they had received advanced pest management training within the past 5 years. These MGs had higher mean scores for confidence, as well as prevention, monitoring, and cultural control and chemical awareness/control practices than those not participating in advanced training. Years of experience as an active MG and confidence in using IPM-related garden activities were correlated positively (r= 0.261). MGs with advanced pest management training were more confident in making IPM recommendations to other gardeners and were much more likely to use IPM practices than MG without advanced training.
