1245 Horticulture Course Description: Open to: Grades 11,12 (One year course) Prerequisite: Biology Content: Students will study an overview of the Horticulture Industry and learn how to identify, grow and propagate common plants, shrubs and trees. Pest control methods, lawn care and maintenance, landscape design and greenhouse operation are other areas of focus. Emphasis will be on projects and lab activities performed in the greenhouse and in the field. Upon successful course completion, students will be able to design and maintain a residential landscape as a future homeowner. Students will also be qualified to apply for entry level positions in the horticulture industry.
