The department provides graduate training leading to the doctor of philosophy in horticulture. Each doctoral student will have a major advisor who will supervise their program of study and their thesis research. Specializations are available in several aspects of crop science: organic and sustainable horticulture, diversified crop production for urban and regional food systems, environmental impact of horticultural practices, environmental regulation of plant growth and development, plant breeding, biochemistry and molecular biology of horticultural plants, microculture and biotechnology, weed control and herbicide physiology, and biostatistics. Students have the opportunity to develop their research projects using vegetables, fruits, trees, ornamentals, turf, specialty crops, or model species such as Arabidopsis thaliana.
The Ph.D. student’s dissertation project will involve an in-depth mentored exploration of a research question and the development of a dissertation in conjunction with a graduate committee of at least four faculty members. A public presentation and defense of the dissertation is required.
The department houses research labs, controlled environment chambers, and greenhouse facilities. Field-plot areas with associated storage and laboratory facilities are available at the UW–Madison Arboretum, Horticulture Research Farm at Arlington, and the Agriculture Research Stations managed by the College of Agricultural and Life Sciences at selected locations throughout the state. In conjunction with the farm at Sturgeon Bay, the world's largest collection of tuber-bearing Solanums is maintained by the Inter-Regional Potato Introduction Project and is available for research use.
The department accepts applications for fall, spring, and summer entry. The applicant's academic preparation should include fundamental courses in the plant sciences such as botany, bacteriology, genetics, and physiology, as well as courses in chemistry (general, organic, quantitative), physics, mathematics, and biochemistry. The academic average should be at least 3.0 (on a 4.0 scale) with evidence of proficiency in subjects related to agriculture and plant sciences.

Specific course requirements
There are no specific course requirements for the Ph.D. in Horticulture. Instead, each student is required to work with the major professor and the Ph.D. committee to design a program of coursework that best meets the individual student's needs and interests. The resulting program of coursework must satisfy the departmental requirements as well as the requirements specified by the Graduate School. The final determination of a student's required coursework is made by the student's Ph.D. committee as part of the certification process.
During their graduate careers, students are required to present a minimum of three seminars in advanced seminar courses and receive a passing grade in each seminar. Advanced seminar courses offered by the departments other than Horticulture may be used to satisfy this requirement.
Graduate School Policies
The Graduate School’s Academic Policies and Procedures provide essential information regarding general university policies. Program authority to set degree policies beyond the minimum required by the Graduate School lies with the degree program faculty. Policies set by the academic degree program can be found below.
Graduate Program Handbook
The Graduate Program Handbook is the repository for all of the program's policies and requirements.
Graduate Work from Other Institutions
Allowed; coursework earned ten or more years prior to admission to a doctoral degree is not allowed to satisfy requirements.
Students are allowed to count no more than 7 credits numbered 300 or above toward the minimum graduate degree credit requirement; if those courses are numbered 700 or above they may count toward the minimum graduate coursework requirement. Coursework earned ten or more years prior to admission to a doctoral degree is not allowed to satisfy requirements.
UW–Madison University Special
With program approval, students are allowed to count no more than 15 credits of coursework numbered 300 or above taken as a UW–Madison Special student. Coursework earned ten or more years prior to admission to a doctoral degree is not allowed to satisfy requirements.
The Graduate School regularly reviews the record of any student who earned grades of BC, C, D, F, or Incomplete in a graduate course (300 or above), or grade of U in research credits. This review could result in academic probation with a hold on future enrollment or in being suspended from the Graduate School.
ADVISOR / COMMITTEE
Every graduate student must have a faculty advisor (major professor) who is on the Horticulture faculty. The major professor advises the student about course work and supervises the student's research. The major professor must approve the student's coursework and research direction. A student may have more than one major professor, in which case at least one of the professors must be a member of the Horticulture faculty.
A Ph.D. committee is composed of at least four members, the major professor, and four more whom must be UW–Madison graduate faculty or former UW–Madison graduate faculty up to one year after resignation or retirement. The Graduate School requires that at least three committee members are designated as readers. Readers are committee members who commit themselves to closely reading and reviewing the entire dissertation. The committee is empowered by the program to advise and evaluate the student with regards to certification, administer the preliminary examination, oversee progress meetings, approve thesis composition, and conduct the final Ph.D. examination.
The student, in consultation with their major professor(s), should select the members of their Ph.D. committee prior to the end of the second semester of graduate study in order to convene a meeting to discuss the student's coursework and plan for certification. Certification is the process by which the Ph.D. committee certifies that the student has completed the formal coursework requirements of the Ph.D. certification is particularly important in the horticulture department because each student has a custom-designed program of coursework. This coursework plan must be approved by the student's Ph.D. committee, and for this reason it is important for the student to convene a meeting of their Ph.D. committee prior to the end of their second semester so that additional courses suggested by the committee may be taken during the student's second year of graduate study The Graduate School requires at least one member of the Ph.D. committee to be from outside the horticulture department. The horticulture department requires that at least half of the committee members have an appointment in the horticulture department. Students choosing Minor Option A typically include their minor professor as a member of their Ph.D. committee. It is the student's responsibility to seek and obtain (verbal) approval from the faculty members selected to serve on this committee.
CREDITS PER TERM ALLOWED
Doctoral degree students who have been absent for ten or more consecutive years lose all credits that they have earned before their absence. Individual programs may count the coursework students completed prior to their absence for meeting program requirements; that coursework may not count toward Graduate School credit requirements.
A candidate for a doctoral degree who fails to take the final oral examination and deposit the dissertation within five after passing the preliminary examination may by require to take another preliminary examination and to be admitted to candidacy a second time.
