Certificates
Certificate programs prepare students for state, county, and city employment in most areas of landscape management, such as park and grounds supervision and state or county agriculture inspection. In the private sector, graduates find jobs in agri-sales and services, organic food production, retail and wholesale nurseries and greenhouses, landscape and irrigation design, landscape contracting, and water management. Any of these majors may be completed in three semesters and one or two summer sessions by students who attend full-time.
