Commercial Horticulture

Click here for printable pages from catalog

The Commercial Horticulture Program is designed to accommodate both working professionals who wish to gain a more thorough understanding of horticulture and students who wish to acquire marketable job skills. Our instructors are professionals in the field of horticulture and our courses are designed to emphasize the theoretical and practical skills needed for work in the Horticulture industry.

The Garden offers a Certificate in Commercial Horticulture. The Certificate program allows students to select one of four tracks of concentration: Plant Production, Landscape Management, Ornamental Plant Identification, or Flower Garden Design.

The Program Coordinator, Charles Yurgalevitch, Ph.D., is the Director of the Garden's School of Professional Horticulture. He earned his BS degree in plant science from the University of Rhode Island, and his MS and Ph.D. degrees in horticulture from Rutgers University. Previously, he was with the University of Florida Extension Service where he developed programs for arborists, landscape architects, and the commercial landscape industry in Southeast Florida.
