Top Tips for a healthier lawn once established.

Maintaining a healthy lawn for your home is easy and doesn’t take a lot of water. Here are a number of useful tips on watering; fertilising and mowing that will help to keep your grass looking healthy all year round.

When to water

  • Water only when your lawn needs it! How often you water your lawn will depend on the weather, the type of grass and soil you have.
  • The lawn should be partly dried out between watering. This lets in air to the root system, stimulates deeper root formation and creates a more drought resistant lawn.
  • Watering everyday or every other day is bad for your lawn and leads to disease and shallow root system.
  • Winter watering is generally not necessary unless it is an abnormally dry season. During warmer months, a good deep watering once to twice a week will be sufficient.

Before watering your lawn please remember to check if water restrictions are in place with your local water authority.

Time of day
Watering your lawn should be avoided during the heat of the day. Water in the early morning or evening to minimise water loss through evaporation.

How Much
Place an ice-cream container on your lawn before watering. When the water in the container is 10-15mm deep, you lawn has had enough water. This can also be tested by a soil meter or simply use a long screwdriver or a spade.

Avoid wasting water through water runoff. To minimise water runoff, test wetting depth of your lawn after watering and only continue watering to wet the full root depth.

How to Mow

  • Your grass should be cut according to the type of grass
    Mow Couch between 20-30mm
    Mow Buffalo & Kikuyu between 20-50mm
    Please Note: The higher the mower height, the deeper and more extensive the roots.
  • Don’t mow if hot weather is expected, or cut the grass shorter than 25mm, as the grass needs enough leaf area to protect itself from the burning effects of the sun.
  • Sharpen mower blades as dull blades encourage plant water loss and introduction of disease.
  • Keep mowing frequency to a rate where not more than 1/3 of the height of the grass is removed at any one mowing.

When to fertilise

  • Fertilise 2-3 times a year in Autumn & Spring to ensure a healthy lawn and deter weeds.
  • Use a balanced plant food that contains nitrogen (N), phosphorus (P) and potassium (K)
  • Applying fertiliser as above will help during water restriction periods to help make lawns stronger and assist in their recovery when the weather cools.

How to irrigate

  • Regularly maintain your irrigation system to ensure maximum uniformity of coverage.
  • Test the evenness of the distribution and the number of minutes to run sprinklers by placing 5 or 6 empty tin cans randomly across your lawn to measure the level of each can.
  • Use soil moisture meters or rain shut off devices where possible.
  • Adjust automatic timers of in ground irrigation systems according to the plant’s seasonally changing water needs.

Footprint test
To check if your lawn needs watering, try this simple footprint test. Walk across the lawn and see how long it takes for the grass to spring back. If the lawn is adequately moist you will hardly be able to see your footprints. If the leaves are very slow to spring back your lawn needs water.

Top Tips

  • Water only when your lawn needs water
  • Water early in the morning or evening
  • Water less often and more deeply
  • Maintain your lawn and lawn care equipment
  • Select a grass that needs less water


  • Lawns help to purify and cool the air. An average front lawn offers the same cooling as 2.5 air conditioners.
  • Lawns are an important source of plant oxygen exchange. A 15x15m turf area will sustain oxygen requirements for a family of 4.
  • Lawns are a natural filter to protect water quality and the environment.
  • Lawns provide noise abatement and glare reduction.
  • Lawns provide safe, high quality, play area for children and pets.
  • A well maintained lawn increases the value of your property.
