Garden Design Certificate Program
The Garden Design Certificate (GDC) consists of a unique curriculum that provides the knowledge and skills you need to succeed as a garden design professional. It features a solid foundation in plantsmanship and science-based gardening techniques, both of which are essential to creating successful gardens for a wide spectrum of projects—from private residences to municipal plantings.
Who should participate? Aspiring professional garden designers, and gardeners and garden designers seeking professional development. There are no prerequisites to start the program, and no prior horticulture experience is needed.

Program Requirements
The program requirements include 23 required courses and 24 instructional hours of elective courses. Botany 1 is recommended to take first or early in your curriculum given it is a prerequisite for many other courses. Students on average complete this program within three years. All requirements for the certificate must be completed within seven years of the start date of our first core course. For the certificate, a grade of at least 70 percent must be achieved for each core course.
