  • determine the environmental conditions required to grow the selected plants and set planting and care schedules accordingly
  • design, install, maintain and program environmental control and irrigation systems
  • perform basic structural repairs to the greenhouse (for example, replace panes of glass, vent motors or environmental control components)
  • co-ordinate and perform exterior greenhouse maintenance (for example, cleaning glass or other glazing and installing adequate drainage)
  • supervise staff in planting, transplanting, pruning, feeding and spraying plants
  • identify and control problems caused by insects, rodents, plant diseases or nutritional deficiencies

  • remove weeds, spray plants with pesticides and apply fertilizers
  • position and regulate greenhouse irrigation systems to water plants
  • set up irrigation systems in soil-less growing media
  • maintain boilers, furnaces, electrical systems and fans
  • construct greenhouses and benches.
Working Conditions
Updated Jul 07, 2016

Greenhouse operators usually work indoors in greenhouses and offices. In some situations, they also may work outdoors in shade houses. Their hours of work often are long and irregular, particularly in the spring and summer months. Those who work in greenhouses that operate on a year-round basis may experience different busy periods. The work can be hectic at times and satisfying customer needs can be stressful. Operators sometimes work with pest management products and will need to use Personal Protective Equipment (PPE) while doing this.

Pruning or picking at heights up to two meters above the ground may be required.

Educational Requirements

However, graduates of post-secondary education programs in horticulture generally have a better chance of advancing to supervisory and management positions. Computer skills are a definite asset.

Certification Requirements

Pesticide Applicator and Dispenser

Pesticide applicators use pesticides (chemicals) to control pests (for example, weeds or destructive insects or animals) as part of their paid employment. Pesticide dispensers sell and store pesticides as part of their paid employment. For related information, see the Arborist, Greenhouse Operator, Market Gardener, Nursery Operator, Pest Control Operator and Turfgrass Management Specialist occupational profiles in OCCinfo.


Under Alberta's Environmental Protection and Enhancement Act and Pesticide (Ministerial) Regulation, you must be a commercial agriculturalist (farmer) or a certified pesticide applicator, or supervised by someone who is certified, to apply a commercial pesticide (for example, insecticide, herbicide or fungicide). You must be a certified dispenser to sell pesticides. There are two types of dispensers in Alberta: (1) Lawn and Garden Pesticide Dispensers sell domestic class pesticides, and (2) Commercial Dispensers sell domestic, commercial and restricted class pesticides.

What You Need

Certification requires successful completion of an exam. A preparatory course is available through home study materials or classroom tutorials. For official, detailed information about certification requirements, contact Alberta Environment and Parks or visit their website.

Working in Alberta

Pesticide applicator and dispensers who are certified by and in good standing with a regulatory organization elsewhere in Canada may be eligible for certification in Alberta if certified pesticide applicators and dispensers in the two jurisdictions have similar responsibilities and competencies. For more information, see "What if I am already certified in another province or territory?" and the Alberta regulatory authority (below).
