The Horticulture, BS no longer admits new students after Spring 2026 and the program will be discontinued Fall 2030. If you have any questions, please contact the department (see contact box).

Students interested in the Horticulture, BS may be interested in the Plant Science and Technology, BS or Agroecology, BS majors.

Horticulturists work to enrich our lives by integrating and applying plant science, environmental science, molecular biology, biotechnology, genetics, physiology, and management. Specifically, horticultural science deals with the development, production, growth, distribution, and use of fruits, vegetables, greenhouse crops, ornamentals, and specialty plant crops (used for flavoring and medicine). Horticultural science is one of the most diverse biological sciences one can study at a university. Not only are the biology and genetics of crop plants interesting, but the application of this knowledge is equally important in a myriad of situations. Undergraduate horticulture majors will obtain specialized training in greenhouse/field management and the production and use of fruits, vegetables, nuts, and herbaceous/woody ornamentals through the bachelor of science degree program.

In addition to obtaining a job with an undergraduate degree in horticulture, the major provides an excellent background for graduate study in the field of plant sciences. Areas of graduate study include plant breeding and plant genetics, horticulture, agronomy, plant pathology, or other related fields such as biology, environmental science, natural resource management, agroecology, and genetics.

Students with either undergraduate or graduate degrees in horticulture have a variety of career opportunities. Recent studies show that there are more jobs in agriculture in the U.S. than there are students graduating with agricultural bachelor of science degrees to fill them. As our world grapples with the need to contribute science-based solutions to feeding 9 billion people by 2050, students trained in the agricultural and horticultural sciences will be called on to contribute.

Horticulture graduates may find opportunities to develop higher-yielding crops or crops that can withstand more stressful growing conditions. Others may find opportunities working on improving qualities such as flavor, appearance, texture, and post-harvest shelf life for a wide range of horticultural commodities from fruits to vegetables to flowers. Sustainable production is an area of growth where horticultural expertise can make a contribution.

The horticulture degree serves as excellent preparation for careers in food production, plant nurseries, community-supported agriculture (CSA), public gardens, greenhouse production, teaching, public parks, vegetable production, urban agriculture, extension- and community-based educational work, work in research labs, and the health sciences. In addition, many horticultural science majors go on to work in public sector jobs including city and state positions with the Department of Natural Resources, the Wisconsin Department of Agriculture, and the University of Wisconsin Division of Extension. Students with degrees in horticulture also work in hospitals (horticultural therapy), aerospace (food and recycling in space labs), and zoos (managing environments for animals and visitors). Although the career opportunities are numerous, horticulture students have a common desire to work intensively with plants to improve our environment and our health.

Advising and Careers

Advising

Each student receives one-on-one guidance from their professional advisor. Academic advisors will help students build an individualized, four-year plan. Many Horticulture majors complete certificates or double majors

Careers

Majoring in horticulture prepares students for numerous career paths, including plant breeding and genetics, applied plant science, food crop production, greenhouse production, urban agriculture, community-supported agriculture (CSA), gardening and landscaping, horticulture education, extension- and community-based education, horticultural therapy, and the health sciences. 

Career Advising

Students are encouraged to begin the career exploration process early in their UW–Madison journey by working with advisors, faculty, and CALS Career Services. These resources can help students reflect on their values, identify career goals, and outline strategies to achieve them. CALS Career Services advisors can help students one-on-one with their career goals, resume and cover letter help, interview prep, and more.

Wisconsin Experience

Internships

Internships are a great way for Horticulture students to get hands-on experience. Many of our students intern at locations that vary from seed companies to greenhouses to wineries to public gardens. Horticulture students also have many opportunities to intern during the year on or near campus at facilities such as the Allen Centennial Garden, the UW Arboretum, and the Agricultural Research Stations. Students have also interned abroad through the International Internship Program.

Research Experience

Horticulture students have many opportunities to get involved in research labs and fieldwork in the department. Students primarily find research opportunities by directly contacting faculty. Occasionally, opportunities are posted on the Student Job Center.

Study Abroad

Horticulture students are encouraged to participate in study abroad experiences. Studying abroad provides students the unique opportunity to contextualize the learning acquired in traditional face-to-face courses on campus. There are many opportunities for Horticulture students to study abroad through short-term and semester-long programs. Students can explore opportunities utilizing the Horticulture Major Advising Page and consulting with their advisor.  

Horticulture students also have some exciting opportunities to participate in short-term field experiences abroad led by program leaders from the Department of Plant and Agroecosystem Sciences. Some of these programs include UW Tropical Horticulture in Costa Rica and UW Food Systems and the Environment in Northern Japan.

Student Organizations

Connect with other Horticulture students and those interested in food and agriculture by joining a student organization. Organizations of particular interest to Horticulture students include People's Farm: Students for Sustainable Agriculture, Slow Food UWWUD Cuisine Committee, Food Recovery Network - Madison Chapter, UW Campus Food Shed, and Minorities in Agriculture, Natural Resources and Related Sciences (MANRRS)

Community Engagement and Volunteering

Students can choose from a variety of volunteer opportunities related to food, agriculture, gardening, etc. The Morgridge Center for Public Service provides resources to help students connect with volunteer opportunities based on their interests and goals.
