Program Description

This 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. This basic knowledge is then interwoven with practical cultural and production methods. 

This certificate is designed for:

  • Nursery, greenhouse and garden center industry professionals
  • Horticulture agents involved in Extension programs
  • K-12 science teachers particularly those who may wish to pursue a Master of Science degree

Delivery Format

Home Campus: University of Nebraska - Lincoln

Method of Delivery: 100% Online - what's this?Program can be completed fully at a distance. Courses are asynchronous, meaning students and instructor may access content at any time and do not have to be connected to the Internet at the same time. If your program includes an internship or practicum, experiences may be completed in the student's local area.

All online courses are accessed via the Internet and use a learning management system. Technology requirements may vary by program and course, but all campuses have basic recommended requirements. High-speed Internet is required.

Interaction with professors and other students may include:

  • E-mail
  • Online discussion boards
  • Phone or video conferencing
  • Other forms of electronic and print communication

Supplemental materials for some courses may include:

  • Printed material and scanned documents
  • Digital resources accessed through university libraries
  • Videos accessed via the Internet, CDs or DVDs
  • Other media

To be successful, students taking online classes should be reasonably comfortable using a computer and the Internet. Learn more about online student tips for success.

Core Courses

Plant Nutrition and Nutrient Management

HORT 824

(AGRO 824) 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).

Plant Physiology

Presents fundamental concepts underlying the science of crop physiology, including crop phenology, canopy development and light interception, photosynthesis and respiration, and dry-matter partitioning.

Floral Crops Production

The principles and commercial practices for producing floral potted crops and cut flowers, emphasizing the physical responses of plants to their environment. Aspects of post-harvest physiology will be covered.

Greenhouse Crop Production


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.

Environmental Nursery Production Practices

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
Elective Courses

Pest Resistance Management

AGRO 896
(RNGE 496; SOIL 496) (1-6, max 12 cr I, II, III) Prereq: 12 hrs agronomy or closely related fields and permission Individual or group projects in research, literature review, extension of course work under supervision and evaluation of a departmental faculty member.

Management of Horticultural Crop Insects

ENTO 803
Prereq: Introductory course in biology. Credit toward the degree cannot be earned in both ENTO 303 and ENTO 403/803. Biology, ecology and management of insect pests of horticultural crops such as vegetables, fruit trees, trees and shrubs, greenhouse crops, turf and ornamentals. Employs IPM strategies to maintain pests below damaging levels while minimizing the use of traditional insecticides.

Entomology and Pest Management

ENTO 812
Prereq: Introductory course in entomology. Principles and practices of managing insect pests. Pest management theory, use of sampling, evaluation, tactics, types of insect pests, and current issues.

Biological Control of Pests
