One of two competency-based horticulture curriculum guides developed by an Illinois project, this Gardening/Groundskeeping guide provides the classroom teacher with specific tasks determined by state industry personnel to be necessary for entry-level job placement. It is intended for horticulture education at the senior high school and two-year college level. For each task, a specific performance objective and evaluation is given along with additional teaching strategies, evaluations, and instructional references. Both students and teachers may refer to Performance Guides and/or Instructor Checklists to determine and judge execution of the tasks. The ten units in this guide are Management-Personnel; Management-Job Actions; Soils; Lawns; Trees, Shrubs, Annuals, and Perennials; Pesticides; Fertilizers; Maintenance of Facilities; Equipment and Supplies; and Equipment Operation and Maintenance. A master reference list is appended. (YLB)
