The Commercial Greenhouse Needs Assessment Survey-1991 was mailed to 201 greenhouse firms throughout Colorado in Aug. 1991. One-hundred-twenty-two usable surveys were returned, a return rate of 61%. The survey contained four sections: Educational Programming Topics; Educational Program Delivery Methods; Needs Other Than Classes; and Personal/Business Data. Results of the Programming Topics section indicated that non-chemical pest control was the subject of most interest (70.6% of respondents), followed by chemical pest control (62.2%). Results of the Programming Delivery Methods section showed that greenhouse operators most wanted workshops (77. 1%). A monthly format (54.7%) was preferred, with evenings (41 .4%) the best time. The Needs Other Than Classes section indicated that greenhouse operators across the state expected visits from the Commercial Greenhouse Extension Agent on an as-needed basis (59.6%), and that 39.2% of the survey respondents were aware of services available from the Commercial Greenhouse Extension Agent. The Personal/Business section indicated that most respondents had a bachelor's or master's degree (53.3%), and were wholesale growers (66.9%) with greenhouses < 50,000 ft2 (67.5%).

About 333 people in the Anchorage area are involved in landscaping and landscape architecture, while about 18% of all farms in Alaska are considered greenhouse and nursery farms. These greenhouse and nursery farms account for $12.7 million in annual sales and comprise 28% of total Alaska agricultural sales. Alaskan horticulture producers have little industry knowledge of landscapers' and landscape architects' demand for Alaska native plants. This survey attempted to uncover the amounts of specific native Alaska varieties of shrubs, trees, herbaceous plants, and ferns that landscapers and landscape architects used in 2004, while also asking what types of plants they would like to use if a consistent supply was established. Landscapers' and landscape architects' business activities and perceptions are also evaluated. Surveys were distributed electronically as well as by standard mail to 165 landscapers and landscape architects in the Anchorage area. An overall 12% response rate provided insight into the commercial demand for Alaska native plant varieties.

A survey to determine teaching methodologies for plant material courses was conducted. A total of 120 surveys was sent to horticulture programs at U.S. universities and colleges. Thirty-nine, 22, and 8 respondents taught a woody plant (W), a herbaceous perennial (HP)/annual (A) course, and a foliage plant course, respectively; 21 respondents taught a combination of theses courses. The following similarities were noted for W and HP/A: 1) about 190 species per Semester were presented usually in a taxonomic order using slides as the primary teaching medium for lecture, 2) the most common student complaint was too much work and memorization, 3) the most common student compliment was the practical and useful nature of the subject matter, 4) in order of importance, plant identification, landscape value, and plant cultural aspects were emphasized. For W and HP/A, 93% and 65% of plants, respectively, were presented as landscape and arboreta specimens. Seventy percent of W courses used Dirr's Manual of Woody Landscape Plants; 58% and 10% of HP/A courses used Still's Manual of Herbaceous Ornamental Plants and Taylor's Guides, respectively.

A survey of Georgia homeowners provided insights about their use of fertilizers and pesticides. Knowledge of current homeowner practices is needed to develop a best management practices manual to be used by Master Gardeners to train the general public through the existing outreach programs. The objective of the training program is to reduce nutrient runoff and garden chemicals and improve the quality of surface water in urban water-sheds. Results showed three of four homeowners did their own landscaping and, therefore, fully controlled the amount of applied chemicals and the area of application. Fertilizers were primarily applied to lawns, but a high percentage of homeowners also applied them to trees, shrubs, and flowers. Insecticides were applied by a larger percentage of homeowners than herbicides. Control of fire ants (Solenopsis invicta) was likely the reason behind the frequent use of insecticides. The desire for a weed free lawn was the plausible motivation behind the use of herbicides, which were used mostly on lawns. Fungicide use was infrequently reported by Georgia homeowners. The pattern of fertilizer and pesticide use suggests that the developed manual should emphasize techniques and cultural practices, which could lower the dependence on chemicals, while ultimately assuring the desired appearance of turf and ornamental plants.
