Study, Learn and Work in Cut Flower Production 

 This course lays a very solid foundation for a career in the Cut Flower Industry; as either a grower, farm manager or in a service business supplying materials, equipment or contract services to cut flower farms.


The Core Units comprise fifteen modules that are divided into the following sections:

  • Introduction to Plants
  • Plant Culture
  • Soils and Nutrition
  • Plant Identification and Use
  • Pests, Diseases and Weeds

Students must complete and pass all of these core units.

2. Plant culture (60 hours)
The purpose of this study area is to demonstrate the ability to care for plants so as to maintain optimum growth and health while considering pruning, planting, and irrigation.


  • Describe how to prune different plants.
  • Demonstrate how to cut wood correctly, on the correct angle and section of the stem.
  • Describe how to plant a plant.
  • Demonstrate an awareness of different irrigation equipment, sprinklers, pumps and turf systems available by listing their comparative advantages and disadvantages.
  • Demonstrate competence in selecting an appropriate irrigation system for a garden, explaining why that system would be preferred.
  • Define water pressure and flow rate and how to calculate each.
  • Explain the need for regular maintenance of garden tools and equipment.
  • List factors that should be considered when comparing types of machinery for use in garden maintenance.

3. Soils and plant nutrition (50 hours)
The purpose of this study area is to provide students with the skills and knowledge to identify, work with, and improve the soil condition and potting mixes, and to evaluate fertilisers for use in landscape jobs to maximize plant growth.


  • Describe the soil types commonly found in plant culture in terms of texture, structure and water-holding and nutrient holding capacity.
  • Describe methods of improving soil structure, infiltration rate, water holding capacity, drainage and aeration.
  • List the elements essential for plant growth.
  • Diagnose the major nutrient deficiencies that occur in ornamental plants and prescribe treatment practices.
  • Describe soil pH and its importance in plant nutrition.
  • Describe the process by which salting occurs and how to minimise its effect.
  • Conduct simple inexpensive tests on three different potting mixes and report accordingly.
  • Describe suitable soil mixes for container growing of five different types of plants.
  • List a range of both natural and artificial fertilizers.
  • Describe fertilizer programs to be used in five different situations with ornamental plants.

4. Introductory propagation (40 hours duration)
The purpose of this study area is to improve the student's understanding of propagation techniques with particular emphasis on cuttings and seeds. Other industry techniques such as grafting and budding are also explained.


  • Demonstrate propagation of six (6) different plants by cuttings and three from seed.
  • Construct a simple inexpensive cold frame.
  • Mix and use a propagation media suited to propagating both seed and cuttings.
  • Describe the method and time of year used to propagate different plant varieties.
  • Describe and demonstrate the steps in preparing and executing a variety of grafts and one budding technique.
  • Explain the reasons why budding or grafting are sometimes preferred propagation methods.

5. Identification and use of plants (60 hours)
The purpose of this study area is to improve the student's range of plant knowledge and the plant use in landscaping and the ornamental garden, and the appreciation of the different optimum and preferred growing conditions for different plants.


  • Select plants appropriate for growing in different climates.
  • Select plants appropriate to use for shade, windbreaks, as a feature, and for various aesthetic effects.
  • Categorise priorities which effect selection of plants for an ornamental garden.
  • Explain the differences in the way plants perform in different microclimates within the same area.
  • List and analyze the situations where plants are used.

6. Pests, diseases and weeds (50 hours)
The purpose of this study area is develop the student’s ability to identify, describe and control a variety of pests, diseases and weeds in ornamental situation, and to describe safety procedures when using agricultural chemicals.


  • Explain in general terms the principles of pest, disease and weed control and the ecological (biological) approach to such control.
  • Explain the host pathogen environment concept.
  • Describe a variety of pesticides for control of pests, diseases and weeds of ornamental plants in terms of their active constituents, application methods, timing and rates, and safety procedures.
  • Photograph or prepare specimens, identify and recommend control practices for at least five insect pests of ornamental plants.
  • Photograph, sketch or prepare samples, identify and recommend control practices for three non insect ornamental plant health problems (e.g. fungal, viral, bacterial).
  • Describe the major ways in which diseases (fungal, viral, bacterial and nematode) affect turf, the life cycle features that cause them to become a serious problem to turf culture and the methods available for their control.
  • Identify, describe and recommend treatment for three different weed problems.
  • Collect, press, mount and identify a collection of ten different weeds, and recommend chemical and non-chemical treatments which may be used to control each.
  • List and compare the relative advantages and disadvantages of different weed control methods

What Opportunities Exist For Cut Flower Growing?

In order for a producer to be successful they need to address several issues:

  • What is the market demand? ie. what will the producer grow, does it have an established market or is this a new product?
  • How will it be presented? ie. as bunched flowers, individual stems or as bouquets?

When a grower decides to produce a certain product the decision is influenced firstly by the constraints of the production area and secondly by the market research conducted before production commences. Potential crops are not just limited to cut flowers but may also include dried flowers, native flowers, cut foliage and fillers for bouquets. Most growers increase their chance to make a profit by growing more then one variety throughout the growing season by choosing species that extend the harvest period. Successful growers will understand the limitations of the growing area through soil analysis, climate, aspect, drainage and irrigation and also the specific requirements of the varieties they choose to grow ie. soil pH, fertiliser etc.

What Do You Need to Learn about Growing Flowers?
There are potentially thousands of different types of cut flowers that can be grown. Success in this business is as much as anything, dependant upon what you choose to grow, when you grow it, how you grow it and where you market it. To properly match your choice of plant with the potential market, requires a very high level of plant knowledge. Consider the following. This is just one type of plant. Consider what you might need to understand about this plant; and then consider what it can take to learn just as much about hundreds of other types of plants.  This course builds that type of knowledge; and does so within the context of growing cut flowers.
