Cut Flower Production BHT221

Who Would Benefit from this Course?

  • Anyone working or wishing to work in the cut flower industry
  • Anyone wanting to buy or start a flower farm (small or large)
  • People wanting to start a small home based business (It's amazing how you much can supplement an income growing cut flowers in even a small home garden)

Cut flower production is an expanding industry worldwide. It has a great deal of export potential, and although most flower producing countries meet the domestic requirements of their cut flower markets, the home market potential in many countries could be further developed. Spending on cut flowers is stronger in some countries than others, the average Australian for example spends far less on cut flowers than say, the average German or Frenchman. Many countries import large quantities of flowers; and even some exporters will import flowers at certain times of the year (eg. when varieties are out of season). Germany for example imports most of their cut flower requirements (up to 70%) with The Netherlands being the largest exporter to Germany. Japan and the United States have the largest cut flower markets though requiring almost double that of Germany.

ACS student comment: "I am enjoying my course and it has given me an understanding of what I need to do once I have completed my course. I find the course to a valuable learning experience. I am able to do it in my own time (I have young children) and the learning is interesting." Melanie Sumpter, Australia, Cut Flower Production course

Understanding How a Flower Deteriorates, can Help You better manage Harvest and Post Harvest

When a flower is harvested, it begins to deteriorate. The rate of deterioration can vary greatly, according to the type of flower, its condition upon harvest, the way it is treated, and the environmental conditions under which it is stored.

The relative importance of these different factors will vary from one variety of plant to another.

  • Type of flower    Orchids, for example, may last for 6 weeks or more as a cut flower, proteas can also last a number of weeks, but many herbaceous plants such as chrysanthemums, dahlias or stock may not last a week.
  • Condition at harvest    If the flower, stem or foliage is damaged the flower can deteriorate faster.
  • Treatment    Certain treatments may prolong the life of the flower (eg. adding sugar or certain chemicals to water which flowers stand in), protecting from exposure to wind, heat or other adverse environmental conditions.
  • Environment    Physiological processes continue to function after a flower is cut (eg. The plant continues respiration).   These processes can be slowed (eg. by lowering temperature or changing composition of gases in the air). By slowing physiological processes, the rate of deterioration can often be slowed. However the natural processes of senescence will still occur eventually. Some flowers die faster than others due to their chemical and internal physiological makeup.
  • Genetics     The longevity of flowers is genetically influenced and varies greatly amongst different cultivars of the same species. These differences in longevity correlate with stem diameter and rigidity. Thicker stems are less likely to bend or break and contain more respiratory substrates for the flowers hence prolonging their vase life.
  • Anatomy and Physiology     This also exerts an effect. For example, a cultivar that produces more ethylene will age faster than one that doesn’t. A plant’s anatomy and physiology are influenced in turn by a number of environmental and technical factors as illustrated in the table below.
  • Light     Light intensity directly influences the efficiency of photosynthesis and hence the carbohydrate content of plants. Flowers with high carbohydrate (especially mobile sugars) content will last longer when cut.    Cooler temperatures, low light intensity and shorter periods of light reduce the life of cut flowers.
  • Temperature    Excessively high temperature during cultivation will reduce cut flower life. High temperatures increase rate of use of carbohydrates and rapid water loss from the plant.
  • Humidity     High humidity is required for optimal flower production in some species, e.g. roses, since it reduces transpiration (and hence stress) and the occurrence of pests such as red spider mite. However, high levels of humidity can increase the growth of bacterial diseases such as grey mould and downy mildew. Ventilation is necessary to reduce these effects and also to reduce ethylene in the atmosphere.
  • Stage of Flower Development     Generally speaking flowers cut at a more advanced stage of development will not last as long as younger ones.
