In order for Extension professionals to effectively help growers use water conservation technologies, it is important to understand the knowledge level and adoption rates growers have surrounding different water conservation techniques. It is also important to understand how grower perceptions of water conservation strategies relate to their adoption. In this publication, we present results of a study designed to understand the knowledge level, adoption rate, and levels of continuance associated with eight water conservation technologies among nursery and greenhouse growers. We also examined whether five characteristics of these technologies (trialability, complexity, compatibility, relative advantage, and observability) predicted grower adoption.

Consumer Perceptions, Attitudes, and Purchase Behavior with Landscape Plants During Real and Perceived Drought Periods
Knuth, M. (Texas A&M University), Behe, B.K. (Michigan State University), Hall, C.R. (Texas A&M University), Fernandez, R.T. and P.T. Huddleston (Michigan State University)
A survey of 1543 subjects was conducted to explore consumer attitudes and behavior during real and perceived drought situations, especially in terms of their landscape purchases and gardening/landscaping activities. Findings could better inform educational programs and marketing strategies on the future demand of plant products and services. Read on, to learn how subjects perceived if the region in which they lived was experiencing drought.

Removal of Nitrogen and Phosphorus from Nursery Runoff using Zeolite and Woodchips
Anna Birnbaum and Jim Owen (Virginia Tech)
Nitrogen (N) and Phosphorus (P) runoff from containerized nurseries contributes impaired US waterways. Virginia Tech aimed to evaluate the effectiveness of ferric aided zeolite sieves with or without bioreactors as a potential BMP for N and P removal of containerized nursery production tail-water (i.e. runoff). The ferric aided zeolite sieve without woodchip bioreactor achieved an average P removal efficiency of 30% with no effect on N removal. Woodchip bioreactors preceding zeolite was effective for N removal with an average rate of 14%. Woodchip bioreactors reduced efficacy at N removal was presumed to be a result of retention times >24hrs and high sulfur concentrations. Ferric aided zeolite+woodchip bioreactor treatment trains may be effective for N and P reduction in nursery tail-water if designed properly to avoid excessive retention times in the denitrification bioreactors.
