Efforts to mitigate outdoor water use in Florida’s urban landscapes increasingly include promotion of regionally appropriate landscaping based on its documented effectiveness. Targeted initiatives, however, require an understanding of mechanisms underpinning low irrigation use in single-family homes with Florida-Friendly Landscaping (FFL). This paper reports survey research conducted in southwest Florida to identify factors associated with irrigation practices among FFL clients. Results indicate that approximately half of survey participants irrigated less frequently than once per week year-round. Aesthetic considerations, horticultural knowledge, and membership in a homeowner’s association (HOA) with rules regarding yard care were key variables underlying landscape characteristics and maintenance, while property values, water conservation attitudes, lawn grass, and in-ground irrigation system use significantly predicted irrigation practices. Homes with in-ground irrigation systems were more than six times more likely to water their landscapes at least once per week during the warm season when residential outdoor water use is at its peak. A $100,000 increase in a home’s market value increased the odds of weekly watering by a multiplicative factor of two, whereas a one-point increase in a six-item Likert scale used to measure a homeowner’s water conservation attitude decreased the odds by 76%. Homes with no grass in the landscape were 71% less likely to water on a weekly basis. Providing homeowners, and HOAs, with educational resources that build on existing support for water conservation could augment adoption of low maintenance plants and sustainable practices in Florida’s urban landscapes.

佛罗里达友好庭院景观灌溉用水的决定因素

减少佛罗里达城市景观中室外用水的努力越来越多地包括根据其记录的有效性促进区域适当的景观美化。然而，有针对性的举措需要了解支持佛罗里达州友好景观 (FFL) 的单户住宅中低灌溉使用的机制。本文报告了在佛罗里达州西南部进行的调查研究，以确定与 FFL 客户的灌溉实践相关的因素。结果表明，大约一半的调查参与者全年灌溉频率低于每周一次。审美考虑、园艺知识和房主协会 (HOA) 会员资格以及有关庭院护理的规则是景观特征和维护的关键变量，而财产价值、节水态度、草坪草和地下灌溉系统的使用显着预测了灌溉实践。在温暖的季节，当住宅室外用水量达到顶峰时，拥有地下灌溉系统的家庭每周至少浇水一次的可能性是其六倍以上。房屋市值每增加 100,000 美元，每周浇水的几率就会增加 2 倍，而用于衡量房主节水态度的六项李克特量表增加 1 个点会使几率降低 76%。景观中没有草的家庭每周浇水的可能性降低了 71%。提供房主和HOA，
