Designed to culminate an ornamental horticulture class, this teaching guide provides information needed for the year-round operation of a school and/or commercial greenhouse. Three units are presented: production schedules, determining harvest time, and cost analysis. Each unit lists major teaching points, learning activities, and reference materials. Included in the appendixes are crop production schedule information for twenty-three annuals, seven perennials, ten vegetables, ten flowering pot plants, and thirteen foliage plants. Also provided in the appendix is cost analysis information, including general cost information, a sample student problem, and specific cost information for six different plants. (JH)
