Student Learning Outcomes -
  • Demonstrate skill required to maintain greenhouse and nursery facilities
  • Identify major types of growing structures and their respective roles in commercial plant production.
Description -
Commercial greenhouse and nursery management as related to the production of plants in California. Emphasis is on greenhouse and nursery operations. Class will focus on organization, management, and production practices used in large and small-scale commercial greenhouse plant production and nursery operations of all sizes. Retail outlets will be addressed as part of the nursery production sequence. Operations and the utilization of technology will be emphasized through use of on-campus facilities and observation of off-site operations.

Course Objectives -
The student will be able to:
  1. organize, schedule, and implement skills and practices used in the production of various plant crops.
  2. maintain greenhouse and nursery facilities including pest control, irrigation system management and operational systems.
  3. identify and select greenhouse components such as framing, glazing and structural materials.
  4. demonstrate management of greenhouse environment through programming of control systems.
  5. demonstrate the development and care of horticultural crops in a greenhouse and nursery environment.
  6. grow greenhouse and nursery crops from preparation of media to planting and cultural management.
  7. recognize the use of greenhouse and nursery operations in different cultures.
Special Facilities and/or Equipment -
Horticultural laboratory, greenhouse, nursery, lath house and related horticultural facilities and equipment. Students provide pruning shears with sheath, work boots, leather gloves and clothing for fieldwork.
