Greenhouse management courses can be included in agriculture or horticulture degree programs. They can also be included in undergraduate minor programs and university extension programs focused on horticulture. Some non-credit greenhouse management courses are available online.
Here is an outline of common concepts taught in greenhouse management courses:
- Greenhouse lighting, cooling and heating
- Greenhouse crop production
- Greenhouse design and materials
- Greenhouse irrigation
- Fertilizers and pesticides
List of Courses
Fundamentals of Greenhouse Management
In a basic greenhouse management course, students are introduced to the various types of greenhouses, such as ridged and furrowed, detached, gutter connected and lean-to greenhouses. Students learn how to produce and culture plants in a temperature-controlled environment and examine variables like humidity, light and nutrients. The course may also go over the business side of greenhouse management, including hiring, supervising employees, monitoring production, producing marketing materials and controlling inventory. A fundamentals course may also provide an overview of growing different types of plants. This basic course generally appears at the beginning of a greenhouse management program.
A nutrients course covers pH measurements and electrical conductivity measurements using water runoff or leachate samples. Students learn how to interpret the results and determine what measures must be taken to correct any nutrient-related problems. Proper nutrient levels can affect plant disease, so students learn about disease control and the impact of epidemics. Some courses may cover plant biotechnology, and students will explore ways to improve plant variety. This course may include lab work.
Insect and Disease Management
Students learn about integrated pest management, which includes arthropod identification, entomology, sampling, micronutrient management and pest management. The disease portion of this course generally covers disease identification, control options and disease prevention. Mechanical options in pest and disease prevention instruction include non-chemical measures like humidity management and the correct placing of insect screens. This course is usually taken after the basic greenhouse management course.
Floriculture Crops and Crop Production
In a floriculture crops and crop production course, students examine the commercial production of various types of greenhouse products, including flowers, vegetables, bedding plants, ornamental plants and container crops. Students learn about potting, watering, fertilizing, transplanting, pruning and harvesting and may participate in hands-on lessons. Instructors also show students how to select and purchase seeds, fertilizers, soil nutrients and various chemicals that treat or prevent plant diseases. This technical course may be taken near the beginning of a greenhouse management program.
