Comment from Student: "In my role within a large Aged Care Facility a great deal of my employment is spent in the area of Turf management and garden care/refurbishment. With ACS I was able to study at my own pace allowing me to put into practise and thoroughly research the subject matter broadening my knowledge and study experience further. I enjoyed the way in which the subject matter was presented as it allowed you to study each subject further, allowing for greater depth, clarity and knowledge. Overall there are not many areas in which the course subject matter will not turn out to be invaluable, everything is covered to allow you to become successful within your own business or place of employment. A big thank you to Gavin Cole [tutor] and all at ACS. It was a pleasure to study with ACS, look forward to further study."  (Craig Ledbury, Australia, Turf Renovation & Repair course)

Why is Turf Renovation Needed

Turf is made up of living things; and like anything that is living, tutf plants can get damaged, get sick, age, and die.

  • Damaged and sick turf plants need to be returned to good health, or they will eventually die.
  • Dead turf plants need to be replaced with living ones, or parts of the turf surface will become bare and subject to erosion.
  • Soil conditions are deteriorating from over use (eg. people walking or driving on it too much); and without improving the soil, the turf will continue to deteriorate.

Traffic over the surface of a can take numerous forms -most of which have potential to damage the turf. The most obvious examples might be vehicular and human movement.

Examples of traffic include:

Golf course

  • Golf carts and buggy wheels which compact soils
  • Human shoes, often with sprigs that rip and tear turf
  • Golf clubs and balls which cause divots and ball marks or plugs
  • Animal grazing which tends to be more of a rural problem.


  • Human use including walking, lying down
  • Erecting temporary structures such as a marquee, tent
  • Ball games of all varieties
  • Irresponsible vehicle use
  • Animal use.

The amount of damage caused by traffic is relative to the amount and type of traffic, but other factors such as environment and turf species are also important factors. The resultant damage that does occur is called turf grass wear.


This refers to damage that takes place when some or all of the above activities take place upon turf. Turf can be slightly discoloured, thinned out or totally killed depending on the type and intensity of traffic, and what type of maintenance and repair procedures are adopted. Firstly, it is important to understand exactly why, where and when turf grass wear is happening and this in turn will enable you to plan control measures accordingly. Remember, turf is there to be used and so turf grass wear will always be a major component of any turf management program.


This is the result of constant traffic or in some cases very heavy traffic. Trail development from shortcuts, such as what is known to park planners and landscapers as ‘lazy paths’, occur. Apart from the crushing of the turf grass itself, this type of wear may also result in the soil particles becoming more densely packed together. This encourages the clay particles to bind together which in turn can cause the soil to become less porous and hence restrict water movement and aeration.

Learn about other things that can damage turf and how to control damage, as well as how to repair and renovate.
