In theResource efficient landscapes in Florida are last few years, FYN’s target audience has expandedthose Florida-friendly landscapes that minimize to include builders, developers, landscapeenvironmental impacts to the greatest extent architects, landscape maintenance professionalspossible. According to the Florida Statutes (FS and real estate professionals. Currently, FYN has373.185), “ ’Xeriscape’ or ‘Florida-friendly landscape’ coordinators working (either full or part-time)means quality landscapes that conserve water with builders and developers in nearly two dozenand protect the environment and are adaptable to counties, and the state office provides supportlocal conditions and which are drought tolerant. for those counties that currently do not have aThe principles of Xeriscape include planning and staff person formally in the Builder/Developerdesign, appropriate choice of plants, soil analysis Coordinator role.which may include the use of solid waste compost, Additional principles that can help reduce theefficient irrigation, practical use of turf, appropriate water quality and quantity impact from landscapesuse of mulches, and proper maintenance.” are preservation or planting of tree canopy, reduction of high maintenance turfgrass, useObjectives: of appropriately sited native plants, and use of reclaimed water for irrigation.
