Our Horticulture Graduate Students

Graduate study for M.S. and Ph.D. degrees in Horticulture is available to qualified students who have an undergraduate degree from accredited institutions in horticulture, or in related plant sciences including botany, crop science, environmental sciences, or professions related to landscape design. Non-plant science degree applicants with substantial experience in related professions may also qualify.

Applicants seeking graduate degrees in horticulture should have adequate preparation in the fundamental sciences such as, biology, chemistry, biochemistry, statistics, physics, as well as undergraduate course work in the plant sciences – e.g., agronomy, botany, ecology, horticulture, genetics, plant physiology, plant pathology, plant anatomy. Applicants lacking adequate preparation may be accepted conditionally, with the provision that recommended undergraduate courses be completed before the degree is awarded.

Many of our students are also engaged either officially or through collaborative projects with various interdisciplinary graduate programs at CSU and/or other affiliated programs.
