Why Fertilising Your Lawn Is Essential

Fertilising the average sized lawn takes less than 10 minutes. It's the simplest, sure fire way to having the best lawn in the street yet amazingly as few as 1 in 4 homeowners ever feed their lawns.

Let’s have a look at some of the benefits of a quality lawn and the role fertilising plays:

  • Beautiful expanse of green
  • Healthier grass
  • Stronger roots
  • Healthy soil
  • Weed free
  • Improved property value

Have you ever seen a lawn that is just nothing short of awesome?

Perfectly trimmed, lush and emerald green without a flaw from front to back?

The single most important part of having a lawn looking that good is fertilising and it's about a lot more than just getting your grass looking green.

A quality balanced slow release fertiliser such as Scotts Lawn Builder will green your lawn and keep it looking great for months, but it’s what you don't see that really matters.

 When lawn grass is given a balanced diet it will be:

  • stronger at every level from the deepest roots to the leaf tips
  • able to resist attack from pests due to improved structural strength
  • capable of repairing itself after physical damage

This stronger, thicker, healthier growth also means roots and soil are better shielded from heat and cold as the density of the lawn works as an insulating barrier.

When a lawn is well fed one of its responses is to develop a healthier, stronger and deeper running root network. This makes the grass better able to:

  • seek out and access nutrients and moisture
  • cope with prolonged extremes of temperature and climate repair itself should physical damage occur

Think of the soil under your lawn as being a complex community of micro-organisms all of which need feeding to their jobs.


These microbes often form symbiotic (mutually beneficial) relationships with or around plant roots. They can:

  • ward off micro-invaders that may damage roots
  • help produce or convert nutrients into forms easily absorbed through roots

Feeding with a quality fertiliser that's balanced to protect the soil and nurture soil micro-organisms will boost your lawn's health and vigour in ways you’d never expect. Healthy, happy soil = healthy, happy plants!

Weeds are often described as ‘adventitious colonisers’ or plants that have colonised an area where they are not wanted. Put simply, they see a chance to grow and take it.


A weak, patchy lawn is the perfect habitat for a weed invasion because there are plenty of gaps for them to get a toehold.

Many weeds are very vigorous annual and, as they spread, they smother the lawn, resulting in ever-expanding dead patches.

The flipside is a healthy, well-fed lawn. Gaps are few and far between and, if a weed seed gets growing, chances are the grass will easily outgrow or overshadow it.

The secret to having a weed-free lawn is to have a well fed and regularly maintained lawn.

A healthy, well-fed lawn has a multitude of benefits for your home.

Here’s just a few.

  • A lush lawn can be 10 deg C or more cooler than hard paved surfaces or exposed soil.
  • Lawn can reduce reflected glare and will reduce reflected noise transmission by as much as 20%.
  • A lawn works like a carbon sink, absorbing and locking away CO2 and generating all important oxygen.
  • A thick, healthy lawn can absorb heavy rainfall without runoff, easing the burden on drains and helping retain water in the soil for other garden plants.
  • Experts say that a top quality lawn can add tens of thousands of dollars to the value of your home by improving the 'kerb appeal'!
