Major in Horticulture

On-campus and Online Options

Apply scientific principles in the growing, marketing, processing and utilizing of fruits, vegetables, flower and foliage plants, trees, shrubs and turf grasses.

Horticulture is both a production and service industry and meeting the nutritional needs of the world population is a growing need. As a Horticulture major, get hands-on experience working in our state-of-the-art labs and growing facilities.

Students in the program are either required or encouraged to have student internships or apprenticeships. Many students are engaged in independent studies with faculty in lab and field research, and work study/hourly jobs in the field or greenhouse.

There are slight differences between the on-campus and online degree programs. Be sure to learn about the details for both options to help you decide what works best for you.
