  • K-12 science teachers particularly those who may wish to pursue a Master of Science degree

The online graduate certificate in Floriculture and Nursery Production Management offers a selection of courses that focus on floral and nursery crop production including business management. Core courses lend a solid science background in order for the student to gain a greater understanding of how ornamental and floral plants grow.

Students who complete this certificate may also wish to pursue a plant-related master's degree such as a Master's of Science or a Master's of Applied Science in Agronomy or Horticulture.

This program is offered as part of the Great Plains Interactive Distance Education Alliance (GPIDEA) and provides you with diverse perspectives on the field. You enroll in courses at the University of Nebraska - Lincoln even though courses may be taught by other Great Plains IDEA member institutions. The certificate comes from the University of Nebraska - Lincoln.

Students who complete this certificate may also wish to pursue a plant-related Master of Science degree or a Master of Applied Science.

Additional Certificates:

The University of Nebraska - Lincoln's Department of Agronomy and Horticulture offers three graduate certificates in horticulture:

  • Advanced Horticulture
  • Ornamental Landscape and Turf Management
  • Floriculture and Nursery Production Management

The department is able to offer these three certificates as a member of the AG*IDEA Consortium.

Career Outlook: Work in the horticulture field ranges from grounds maintenance staff who require no formal education to scientists who need a minimum Ph.D. According to the U.S. Bureau of Labor Statistics (BLS), grounds maintenance workers held 1,309,300 jobs in 2016. The BLS reported from 2014-2024, there would be an 11% increase in employment for grounds maintenance workers. The projected amount of job openings during this period is 146,300. The BLS projects that businesses in green-industry occupations and careers that protect the planet will increase.

Core Courses

Course NumberCourse NameCredits
HORT 842BPlant Physiology3
Presents fundamental concepts underlying the science of crop physiology, including crop phenology, canopy development and light interception, photosynthesis and respiration, and dry-matter partitioning.
HORT 843AAdvanced Greenhouse Crop Production4
Principles and practices of commercial production of greenhouse crops involving crop scheduling, greenhouse construction, heating, cooling, growing media, pest management, nutrition, fertility, growth regulation, irrigation, post‐harvest handling, and marketing of greenhouse crops.
HORT 844AEnvironmental Nursery Production Practices3
In this course, cultural nursery crop production practices will be presented with consideration of current recommended Best Management Practices, conservation of resources, scientific research-based investigations related to nursery cultural practices, potential risks to nursery personnel and off-site movement of airborne materials and effluents to surrounding areas
HORT 896Plant/Water Relations3
Presents fundamental concepts underlying the science of crop physiology, including crop phenology, canopy development and light interception, photosynthesis and respiration and dry-matter partitioning.
HORT 824Plant Nutrition and Nutrient Management3
Macro- and micronutrient elements and their function in the growth and development of plants; the role of single elements; interaction/balances between elements and nutrient deficiency/ toxicity symptoms as they affect the physiology of the whole plant; and the relationship between crop nutrition and production/environmental considerations (e.g. yield, drought, temperature, pests). Prerequisite: AGRO 824

Elective Courses

Course NumberCourse NameCredits
