This competency-based horticulture curriculum guide is designed to provide secondary and postsecondary horticulture teachers with a task-oriented program in floriculture. It contains a master resource list, a listing of floriculture resources available from various states, and 89 competency task sheets organized into nine competency areas. These areas are maintenance and repairs; field soils; media mixes; planting and propagating plants; cultural and environmental control practices; irrigation practices; plant pest and disease control; harvesting crops; and packaging, storing, and shipping. A task statement, a performance objective, suggested learning activities, evaluation procedures, selected resources, and a performance guide are provided in each competency task sheet. Instructor check lists designed to help instructors determine acceptable levels of student performance are also included in the units. (Related competency-based horticulture curriculum guides in the areas of gardening/groundskeeping and turfgrass maintenance are available separately through ERIC--see note.) (MN)
