The Clarence W. Schrenk Program in

Horticulture, Landscaping & Turf Management

Associate in Specialized Technology Degree

The goal of the comprehensive training given in the Horticulture program is to prepare students to enter the Horticulture Industry and to advance quickly into management and supervisory positions. Through experience and support courses, students will also be able to own and manage horticulture and landscaping businesses of their own.

A strong curriculum of theoretical courses is taught, covering topics that include: Arboriculture, Herbaceous Ornamentals, Landscape Design and Construction, Botany, Woody Plant Identification, Plant Propagation, Turf Establishment and Maintenance, and Nursery Management.

Theoretical studies are reinforced by substantial, practical lab time in which students are required to complete many different campus installation, construction, and maintenance projects. In order to accomplish goals as set forth in the project assignments, the students utilize various hand tools, power equipment, specialized machinery, and vehicles, including chain saws, leaf blowers, tampers, skid-steer loaders, tractors, carts, and trucks.

The graduates of the program are well prepared to enter the horticulture industry at entry-level supervisory/foreman management positions and to work for a variety of employers, including tree care companies, landscape design/build firms, grounds departments, private estates, golf courses, public gardens, and arboreta.
