Horticultural Sciences

Restart your search

Horticultural Sciences provides students with the knowledge and skills needed for a career in the production and management of plants and soils for food, fiber, forage, oil, recreation, landscaping and the enhancement of the human environment. Graduates have the technical and scientific skills as well as the communication, computational, leadership, and interpersonal capabilities necessary to function effectively as professionals.

Our graduates enter careers in:

  • Retail Horticulture
  • Horticulture Education
  • Horticulture Research
  • Horticulture Consulting
  • Recreational Facilities
  • Governmental Agencies, Leadership, Policy, Management
  • International Agricultural Development
  • Agribusiness Sales
  • Extension

Based upon interest areas and career goals, you may select one of two areas of emphasis in the Horticultural Sciences program.

  • Horticulture & Plant Science: emphasizes coursework in botany, plant physiology and horticulture science as well as an undergraduate research experience
  • Horticultural Plant Production & Management: emphasizes horticultural production and business skills. Careers include managing nurseries, greenhouses or fruit/vegetable enterprises; installing and maintaining ornamental plants; and managing botanical gardens.
After wandering around in several majors, I found my home in horticulture. Walking into classes each semester and recognizing friendly faces makes the learning experience that much more enjoyable! And the College of Agriculture faculty and staff are the most friendly, helpful, and welcoming people in the university.
