Learn to be a Landscape Professional

  • Designer
  • Contractor
  • Manager

This course is hands on and relevant to the needs of today's world and for the right candidate, will lay an outstanding foundation for a professional career in landscaping.

Contrary to popular opinion, a garden designer does not need to be good at drawing (though some are) or an expert at computer graphics. Producing a plan is only important in its capacity to instruct a landscape builder. Once the garden has been constructed the important thing is the finished product - not the drawings it was built from. Some of the best garden designers produce rather messy drawings and others who produce very attractive drawings, sometimes don't produce anywhere near as attractive gardens.

Working in Landscaping

Graduates from this course may work in either landscape design, landscape management, construction/contracting or project development; or perhaps a related situation consulting, teaching or writing about landscapes. 

This is a huge industry, with a great diversity of opportunities.

Garden Design is just one unique aspect of a profession that blends science with art.

Landscape designing a garden involves:

  • Meeting with clients to determine their needs and desires.
  • Surveying a site, and creating a base plan (drawing)
  • Determining potentials and limitations (What is and is not feasible)
  • Systematically working through a logical design process, to develop, step by step, a concept that is physically achievable, as well as being functional and aesthetically appropriate.

The amount of work available in garden design has increased in recent decades, particularly in more affluent parts of the developed world. In situations where both husband and wife work, and money is relatively available, all home services including garden design have become growth industries.


Some landscapers both design and build the landscape. Some may even design, build and continue to manage the landscape after construction.

Others may be garden designers work full time doing nothing but garden design; or project managers who after building each garden, move on to a new project.

Some combine garden design with another job, such as garden consultancy, garden writing or growingt plants in a nursery (which are used on their projects).

Garden centres sometimes offer a garden design service to entice people to buy plants from them. They may employ, or do a deal with a designer; or the owner or staff may even go and learn design themselves.

Most landscape designers are self employed. Some other employment opportunities for landscape designers include being employed by places such as:

  • Horticultural businesses (e.g. garden centres landscape contractors).
  • Planning or design firms (e.g. architects, engineers, town planners)
  • Developers or construction companies
  • Parks authorities
  • Sporting facilities
  • Theme parks

Consultants may charge anything from low to extremely high rates for their design work. A garden design for a 500 to 1000 sq. metre property (home) may cost as much as a person’s weekly wage; or much more if designed by a well known and prestigious designer. The ability to command high fees will depend upon reputation and that will only develop over time, and if you are able to develop a unique and popular flair to your work.

Designers who are able to obtain employment (part time or full time) with others should be able to earn a professional level salary.

Advancement in this industry is most dependent upon reputation. If your work becomes famous, you will also, and your ability to charge more will increase. In some places, a good way of advancing your career as a designer is to create display gardens in a major garden show. Designers who win medals at Chelsea Flower Show (London) or MIFGIS (Melbourne) for instance, will find it easier to get work; and often be able to command higher fees.

Frequently Asked Questions

Question: How can I learn the practical side of landscaping?

Answer: The question of practicals is a complex one....There are literally hundreds of different things we do throughout a course such as this.
ThIs 2100 hour Landscaping learning bundle is an excellent course, and it can be done anywhere - you do not need to attend practicals or workshops in any particular place at any particular time BUT ....there is a lot of work that goes well beyond just theory; and the way in which that is tackled can be extremely diverse, and different for every student.

Here are just a few examples:
1. There are a lot of tasks that involve vesting gardens or sites to be landscaped; and observing, conducting surveys , photographing or otherwise recording what is observed, undertaking an analysis etc.
- Some of these tasks may involve using improvised survey equipment (if you do not have more sophisticated equipment, we can show you how to improvise).
- Some may involve doing an analysis of soil.
- Some might involve planting something or growing something.

2. Some tasks involve networking with industry -making contact with and interacting with people who work in landscaping or associated support industries

3. Some tasks involve pbl projects (a system that has been tried and proven not only by ourselves but by many highly reputable international universities (see http://www.acs.edu.au/enrolment/problem-based-learning/default.aspx ) For instance - this has been shown to work just as well in providing practical learning, in medical degrees in the USA, as running actual laboratory classes.

4. Research projects: You need to visit, observe, interpret things in places like landscape material supply yards, soil supply companies, machinery and tool suppliers, etc.

5. Plant Collections: This is a tried and proven way of learning plant knowledge....we have adapted it for distance ed. and used it for 30 years....feedback from graduates and employers has been overwhelmingly positive. It works!

I find that the question of 'practical' learning is always one that people feel cannot be achieved through correspondence; and I understand that apprehension; but we have been grappling with that problem and contriving solutions for 30 years. Over those 30 years, we have been given more and more tools (eg. video, internet, fax) that make our job easier. Over the same period, funding for practicals in government colleges has become tighter and tighter; and today, with huge funding pressures, much of the hands on instruction that used to be part of face to face courses, is not as practical as what you get from our correspondence courses.

Question: Do I need to travel much to do practicals?

Answer: The answer really varies greatly from one student to the next. It can depend very much upon what you choose to do, where you live and what is going on in your locality at the time you come to do an assignment.

If a student has difficulty doing something, they can liaise with a tutor and always find an achievable solution - sometimes for instance, if you need to visit a garden and you are living in the north of Sweden, trying to do the assignment in the middle of winter -the tutor might direct you to do a 'virtual visit' on the internet. If you cannot visit an ideal site to conduct a physical survey, we may need to explore and find a site closer to home that achieves the purpose, but is more achievable for you.

When issues arise that are a problem, our approach to finding solutions is very much on a case by case basis. This approach has worked for 30 plus years, and our students do learn well because we charge a level of fees, and have an infrastructure that allows us to take time to do this if necessary.

For the majority of students though, the assignments and set tasks are written in a way that gives them sufficient flexibility that our intervention is not needed.

You need to understand that every student is doing a different mix of assignments: we may have 50 people doing this course, but it's rare for more than 2 or 3 to be living within several hundred miles of each other - as a consequence, the assignments are presented in a way that gives the student a framework and beyond that they are making choices themselves about where they travel to.
