This manual is one of a 3-volume series prepared to guide the high school vocational agriculture teacher in teaching ornamental horticulture. Chapter I introduces the reader to ornamental horticulture and gives examples of how the subject can be integrated into an existing agriculture curriculum. Chapter II is devoted to the public relations implications of an ornamental horticulture program. Chapter III deals with the layout of physical facilities, discusses garden plot layout, and includes a list of plants recommended for each season. Presented in outline form so it may be used as a teaching unit, Chapter IV, "The Nursery Industry," includes suggestions for individual student and class projects. Suggestions on how to initiate an instructional program in ornamental horticulture in high school curriculums are presented in Chapter V, and Chapter VI considers the relationship of plant production and student project activity to classroom work as well as legal implications of plant sales. Chapter VII contains a suggested calendar of monthly operations in the garden and nursery and a list of monthly topics for classroom presentation. Information plans and illustrations describing construction of a lathe house for use in high school ornamental horticulture program conclude the document. (DM)
