The Horticultural Sciences (HOS) graduate program is collaboratively managed by the Environmental Horticulture (HSE) and Horticultural Sciences (HS) departments, providing Master of Science (with thesis or non-thesis tracks) and Doctor of Philosophy degree options. A combined bachelor's/master's accelerated degree pathway is also available. For details, consult the graduate coordinator. The program's Graduate Faculty comprises departmental faculty alongside researchers at University of Florida Research and Education Centers across the state. The Ph.D. represents a research-focused credential awarded based on comprehensive expertise, specialized knowledge, and demonstrated capacity for independent study, evidenced by an original dissertation exhibiting both scholarly rigor and exceptional writing quality. Accordingly, doctoral curricula offer greater flexibility compared to M.S. programs. Ph.D. candidates must complete 90 credits post-bachelor's degree, with course requirements tailored to individual research areas. Students may transfer up to 30 credits from a master's program, provided they were completed within seven years (unless approved by petition). While the Graduate Council establishes no fixed Ph.D. course mandates, all programs emphasize rigorous research training.
