A Quick Guide to Fertilisers

Date: 28-02-2017

Lawns that are constantly growing and being mowed are prone to losing nutrients.  A simple and quick fertilise will replenish the vital nutrients that your lawn needs to survive and thrive and should be part of your regular lawn maintenance.

At Great Aussie Lawns we have three different fertilisers and depending on the needs of your lawn you may need a specific nutrient analysis from your fertiliser. 

First a quick lesson on Fertilisers!  A complete fertiliser contains all three of the major nutrient elements nitrogen (N), phosphorus (P), and potassium (K). Nitrogen helps to produce the green leaves in the plant, phosphorus and potassium give the lawn good root development, strength and disease resistance.

When viewing the fertiliser make up it’s shown as three numbers (NPK), which is the analysis, like our Starter Fertiliser N:5 P:6 K:6.

Starter Fertilisers for New Lawns (Starter – N:P:K 5:6:6)

A Starter Fertiliser is essential for success in establishing a new lawn from seed or getting your instant turf off to a good start.  The higher level of Phosphorus gets the roots growing while developing a good root structure.  This is vital for new lawns.  The Potassium helps build strength and resistance to disease by building the body of the plant and in this analysis there's a lower Nitrogen level. 

Also safe for pets and kids!


Fertilisers for Established Lawns (Renovator – N:P:K 22:5:7)

This is the ideal fertiliser for established lawns and is suitable for all lawn types.  The analysis shows that Landscape Range Renovator Fertiliser is higher in Nitrogen  for a great boost in colour, with results you’ll see in just a few days.  Plus higher Potassium for strong roots and the ability to fend of disease.

Use Landscape Range Renovator Fertiliser four times a year.


Controlled Release Fertilisers (Gold Pro – N:P:K 22:3:4)

A controlled-release fertiliser releases nutrients gradually into the soil and is designed to provide your lawn with a steady controlled release of nitrogen over an extended period.  When applied it will last 10-12 weeks.

It will provide a continuous green colour over a period of time as the Nitrogen is released slowly.  Great for use on sandy soil profiles, high traffic areas and particularly in Summer when frequent watering can strip nutrients through the soil.  Use this four times a year.


Some final fertilising tips that will make a big difference to your lawn:

Feed your lawn with fertiliser...

  • When you’re establishing a new lawn (Use a Starter!)
  • When you’re oversowing to repair patches (Use a Starter!)
  • In Spring, when the lawn begins to take off again after winter (Use a Renovator!)
  • In Autumn to give your lawn a booster prior to winter cold (use a Renovator!)
  • In Summer when it needs help absorbing nutrients and steady release will benefit it most (Use A Controlled Release)

Fertilise when the lawn is dry.  Applying fertiliser to a wet lawn can burn it.  If your lawn is wet ensure you water the fertiliser in well after applying.

Lawns in Tropical parts of Queensland may require more regular feeding when the wet season strips nutrients from the soil.

Using a Fertiliser Spreader makes the job easier and provides an even distribution.  Depending on the area you can use a small handheld spreader or a push broadcast spreader for larger jobs.
