Online Graduate Courses

The Horticultural Science Program offers a number of online horticulture courses. These may be taken as part of a certificate or degree program, or by non-degree-seeking students on a course-by-course basis. For those interested in taking individual courses without enrolling in a degree or certificate program, you must first enroll as a Post-Baccalaureate Studies (PBS) student. To learn more about enrolling as a PBS student or registering for courses, visit our Apply page.

Visit NC State’s Graduate Online and Distance Education tuition rates page for detailed information about the fee schedule for online courses. The current estimated cost per credit hour for 2015-2016 (North Carolina residents) is $407.47 for graduate-level courses.
