Qualification Statement of Attainment

Learn How to Maintain and Repair Turf

Turf grasses grow in a slightly different environment to other garden plants. As such, turf repair and restoration requires a different skill set and knowledge base to other plant maintenance.

  • Learn how to approach and resolve problems with turf.
  • Learn to inspect all turf - any turf whether high or low quality deteriorates naturally over time.
  • Develop your ability to diagnose and treat problems in turf.
  • Understand why periodic repair or more comprehensive renovation is essential if turf is to remain functional and continue looking good.
  • Turf Repair and Renovation is relevant to sports surfaces, home gardens and amenity turf in parks and commercial areas.
  • A CV enhancing qualification for anyone working with turf, or who would like to.
  • The course has been extensively developed and is taught by highly experienced and qualified horticulturists.

Please note – This course assumes students possess some basic knowledge of turf, equivalent to our Turf Care I course.

Add Turf Repair to Your Green Keeping Skills

Turf grasses grow closely together and so must compete with one another for water and nutrients. In addition, they are frequently mowed, and are often walked upon by people and animals as well as compacted under machinery. This means that a unique approach has to be taken for the repair, restoration and maintenance of turf.

Understand how to maintain healthy turf

  • Learn about industry practices for undertaking turf repairs and renovating damaged turf.
  • Learn to recognise symptoms of poor turf health, carry out inspections, and perform operations to maintain turf longevity.
  • Learn about turf cultivation and techniques for improving the health of turf.
  • Find out about irrigation systems for turf, and gain an insight into the turf production industry.
  • Learn how to approach and resolve problems with turf.
  • Develop you knowledge of the different tools and equipment available and selecting the correct tools for the job.
  • Learn about maintaining your equipment.
  • Understand more about weed control using different techniques - chemical and non-chemical.

Lawn Renovation after Winter

After winter, most lawns look a little worse for wear, some are a disaster zone. Spring is an opportunity to reinvigorate the grass as it presently exists, or to start afresh.

A Fresh Approach

In areas where the lawn has had poor attention over many years, your best choice may be to dig up the existing area and replace it with new top soil and turf.

A rotary hoe will make quick work of a hard job. It will break up compacted heavy soil and is excellent for digging in soil improvements like gypsum, organic matter, fertiliser, etc. You can also use a rotary hoe to dig up an old turf although it is recommended that you spray it with a weedicide a few weeks before if you plan to replace the lawn with new turf.

An easy to use 8 hp rotary hoe that can dig to a depth of 200 mm is often ideal. It is self propelled and has variable speeds.

Renovating What You Have

If your lawn just looks old and tired and in need for a little TLC, then renovating your existing lawn is all you need do. With a few simple steps, your old lawn will come up lush, green and thick.

Your first task should be to inspect the site, and then act in any of the following areas that pose a problem:

1. Are there weeds present?
  • If so, eradicate by using chemicals\or hand weeding.
  • If the lawn is totally covered in weeds, then it is sometimes better to kill the lawn (e.g. spraying with glyphosate), then replant with seed or turf. Take care that weed seeds don’t remain in the soil; or if they do, make sure they are not given a chance to compete with the turf.
2. Is the ground hard/compacted?

Compacted soil frequently causes bare patches in the lawn. People, machinery, pets, etc. repeatedly moving across the lawn cause the soil to compact and result in poor root penetration and growth. Clay soils are the most susceptible to this problem because they have smaller air spaces. To overcome this problem you need to aerate the soil:  

  • Small areas – use a garden fork to spike the soil to a depth of at least 10 cm. Work the fork backwards and forwards to enlarge the holes. A hollow-tined fork, which digs out cigar-shaped plugs of soil can also be used for this purpose.
  • On larger lawns, use a spiked roller.

After holes are made, use gypsum and/or sand to penetrate into the holes so that they aid in keeping the soil aerated.

3. Are the turf species appropriate?

Some grasses are more adaptable and hard-wearing than others. A mix of species will generally perform better than just one or two species. Over sowing with another species or more of the same species will help maintain thick lawn.

4. Is soil nutrition adequate?

Lawn fertilisers, which are high in nitrogen, will rapidly fix the problem of yellow leaves caused by low nutrients. It is better to apply small amounts at regular intervals (4-6 weeks) during the growing season rather than one large dose at the start of summer. Take care that you do not over fertilise the lawn as this is wasteful, excess nutrients can end up polluting waterways, and the soil may become too acidic. Check the soil pH – apply lime if the soil pH is less than 6.0. 

5. Is drainage a problem?

Most grasses prefer well drained soil. If the soil remains waterlogged you will need to install drains to carry the water away.

6. Is the soil too dry?

Sandy soils dry out very quickly and will require additions of organic matter to overcome this problem. Some products are on the market to help soils hold extra water and these may be helpful.

Another cause of dry soil is thatch. Thatch is the build up of old undecomposed roots and stems on the soil surface and prevents water, nutrients and air penetrating the soil, creating dry, water repellent spots in the lawn. Thatch should be removed either by rake or using mechanical de-thatchers.

How to top dress a lawn

The main purpose of topdressing is to smooth out uneven lawn surfaces. Other benefits are to help the grass grow evenly after de thatching, to assist over sowing and to add nutrients.

  1. Use a light sandy loam as the topdressing material. It should be almost dry at the time of application.
  2. Distribute the topdressing with a shovel in small heaps across the lawn. 
  3. Spread thinly so that the tops of the blades can still be seen, using the back of a rake, a topdressing rake, or a spreader.
  4. Make sure that all depressions are filled in, and that the surface is level and smooth.
  5. If over sowing, add a pre planting fertiliser to the topdressing mix.

What You Might Achieve

Every student is different in what they achieve from this course. For some it may be improved career or employment prospects, while for others, it is simply a greatly improved capacity to understand and manage lawns and turf surfaces.

Our Students Say

"Thanks for the videos, they are great! I got a lot of information from them. The Turf Management video is practical and easy to understand. Plant Propagation is a video every student should watch because out here in the real world no-one would give out such information. The Rose Growing Tape was very beneficial to me as I have about 60 odd roses. I thought I knew a little about them but this tape is a real eye-opener." (Kelvin, Horticulture 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, Turf Repair and Renovation)
