Cut flower growing has experienced rapid expansion in increasingly affluent countries. This has resulted in an increased demand for training in the skills and knowledge required by the industry. The course provides a thorough basic training for the commercial cut flower grower.


ACS Graduate comment:  I consider that my success in recent years is directly related to the training I have done with the ACS. The materials were spot on, and the tutors were superb....(read more of Lana's inspiring story that includes owning breeders rights to a specific Flannel Flower and running a successful export business)

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.

 The flower industry has always been in some respects a luxury; which has thrived as economies thrive.

As the developing world continues to become more affluent, this is an industry that seems set to also grow.

Flowers are in demand all year round with peak requirements at special times of the year, such as for Valentine’s Day, Mother’s Day, Easter, Christmas, and so on. Particular festivals often influence the type of flowers required eg. red roses for Valentine’s Day.

Floriculture businesses produce fresh and dried flowers and foliage for a mixture of markets such as wholesale flower markets, florists and retail outlets, and in some cases for export. The wide range of different flowers and foliage grown can include roses, carnations, orchids, native flowers, bulb and annual flowers, and tropical flowers. Some flower farms also grow flowers in open fields for their essential oils.

Floriculture includes propagating, growing and marketing of all cut flowers, flower seeds and seedlings, bulb growing, nursery operation, chemical protection of plants, post-harvest storage and handling and use of preservatives.
A proportion of flower production takes place in greenhouses. In addition to the greenhouse production, floriculture encompasses outdoor production of herbaceous plants and flowers, and field production of cut flowers.


Cut flower growing work may vary a great deal, depending upon the type of plants grown, growing techniques used, and the harvesting methods.

Crop Options

  • Annual or Perennial herbaceous flower crops (e.g. carnations, sunflowers, poppies, stock, statice).
  • Bulbs (e.g. tulips, daffodils, gladioli, iris) - can sell both the bulbs and the flowers.
  • Woody perennial plants (e.g. roses, proteas, heathers).
  • Tropical or greenhouse plants (e.g. orchids, gingers, heliconias).

Production Methods may include:

  • Row crops in open paddocks.
  • Greenhouse Production.
  • Hydroponic Growing 
  • Potted colour (growing pots of flowers)
  • Harvesting from the wild or gardens

In garden settings, gardens created with beds of cut flower producing plants may have a dual purpose (e.g. a large rose garden may attract visitors who pay to enter the garden, buy food at a café, and the flowers may then be harvested and sold as cut flowers through a flower market).

Some rural producers may grow cut flowers along with other things as a cash crop. A market gardener, for instance, who is primarily growing vegetables, may have a hedge of proteas or banksias around their property acting as a windbreak, but also providing a flower crop that can be sold for additional income.

Work tasks may vary depending upon what is grown, how flowers are grown and how they are harvested stored and marketed.

Growing annual flowers, herbaceous perennials, or bulbs in open paddocks may be relatively low tech. Routine tasks may include cultivating paddocks, planting, weeding, watering, spraying pests, harvesting flowers, lifting and dividing bulbs, post-harvest handling (e.g. packing, applying chemicals to lengthen the flowers lifespan), and shipping.

Flowers grown in a greenhouse or in hydroponics can be a relatively high-tech operation, requiring a high level of scientific knowledge and hands on technical skills. Some flower farms use very sophisticated equipment to control light, temperature and humidity conditions in order to manipulate flowering times. Both potted and in ground plants can be  grown this way to produce flowers all year round, or at times of the year when they are not normally available.  People who work on these more sophisticated farms will still need to get their hands “dirty” at times - but with a high level of automation, they may sometimes feel that their job is more akin to a factory manager than a farmer.

People who work with perennial flowers grown as row crops, as hedges, or in garden beds, will have a different daily routine to those growing annuals. For instance, a big part of rose growing is pruning - something which may be done rarely if at all with some annual flowers. It can take one to several years to establish a planting of woody perennials, before you begin harvesting, but once producing, you do not need to replant each year.

Cut flowers are always in demand.
You may already be growing flowers; or might be planning on developing something on a property that you already have.

  • Farmers will sometimes grow cut flowers as a sideline to provide added income and diversify their risks
  • New comers to the industry may be seeking to buy an established farm, or set up a new one
  • Even small properties of an acre or less can be large enough for a viable cut flower farm; particularly if you are growing very productive cultivars, or using technology (eg. hydroponics or greenhouse growing), to enhance productivity.

Demand for flowers exists twelve months of the year; particularly for weddings, funerals and other occasions; but demand heightens occurs at certain times (e.g. St Valentine’s day).

In many places around the world, certain flowers are seasonal; many cut flower growers have built a successful business based upon providing flowers outside of the normal season. Other growers have achieved success by finding and introducing a type of flower that is not readily available in a market.  

Some flowers are always in high demand and low supply. Everyone tends to love orchids, roses and lavender, for instance, so these are always highly saleable - but the farmer does need to be careful to not oversupply the market, 

What You Need?
A cut flower grower needs land, knowledge and somewhere to sell. 
This course can set you on the right path to gaining the knowledge and finding potential customers. If you already have some land, you are ahead of the game before you begin; but don't be deterred if you don't.

It is a valuable skill to be able to grow a healthy, unblemished flower that is durable after harvest. Once you learn that; you will be an attractive employee for any flower farm seeking staff.

Some growers will sell their produce direct at the farm gate and to retailers (perhaps through a wholesale market stall, or off a truck), while others may sell through an agent.

A more sophisticated greenhouse or hydroponic flower farm will normally be a much greater initial investment, but can be highly productive in the produce it yields per acre per year.  The cut flower farmer here needs to be a very good business manager and employ highly skilled technical staff, if the farm is to return an appropriate profit for the investment made.



  • To understand the fundamentals of growing cut flowers on a commercial basis
  • To pinpoint flower crops that will do best in your region
  • To understand the business aspects of running a cut flower enterprise

The cut flower trade is a healthy, dynamic and expanding horticulture industry sector - opportunities abound for those with the skills and knowledge to join this exciting trade.

This course is suited to those already working in the field but who would like to improve their career prospects, to those looking to set up their own enterprise or for those who would like to work in this field and advance in the industry.
