The 88 activity guides in this document are intended to supplement the initial or organized instruction of the agricultural teacher at the secondary educational level. Some of the activities require one student to complete, others may need two or more students working in a team. Some activities also require followup checking within a few days to months. Thus long-range planning and activity schedules are experienced by the students, and are typical of out-of-school work experiences. The activity guides cover the areas of grounds maintenance (41 activities), greenhouse (21 activities), landscaping (16 activities), and horticulture mechanics (10 activities), and are numbered consecutively for convenience in making assignments to the students. Each guide includes the title of the activity (e.g., pruning established evergreens, sodding a lawn area, and composting), tools and equipment needed, materials and supplies needed, procedures, special information, and a referral number for cross-reference between or among other guides related to the activity to which the student is assigned.
