One of the most common questions we get is: “What’s the best fertiliser for my lawn?”. With so many products on the market, it can be tricky to know where to start. In this guide, we’ll break down what fertiliser actually does, the different types available, and when to use them for the healthiest lawn possible.
What Does Lawn Fertiliser Do?
Just like any other plant, your lawn needs sunlight, water, and nutrients to thrive. Over time, soil can lose vital nutrients that your grass relies on — that’s where fertiliser comes in.
The three key nutrients lawns need are known as NPK:
- Nitrogen (N): Promotes strong leaf growth and rich green colour.
- Phosphorus (P): Supports healthy root development.
- Potassium (K): Helps your lawn build strength, resist stress, and use nitrogen efficiently.
In addition to these macronutrients, premium lawn fertilisers also contain a mix of micronutrients such as iron, calcium, zinc, and manganese — all of which help your lawn stay balanced and healthy.
Types of Lawn Fertilisers
There’s no one-size-fits-all fertiliser — each type has its own benefits depending on your goals and lawn needs.
Granular Fertilisers
Granular fertilisers are small pellets that are easy to apply and ideal for most lawns. Many are slow release, meaning they feed your lawn gradually over several weeks. For best results, use a fertiliser spreader to ensure even coverage.
Liquid Fertilisers
Liquid fertilisers are absorbed through the leaf, so you’ll see results faster. They’re great for giving your lawn a quick pick-me-up or correcting nutrient deficiencies. Apply with a knapsack or pressure sprayer for even distribution.
When to Apply Lawn Fertiliser
For long-lasting results, fertilise your lawn two to three times per year using a quality granular fertiliser. A simple way to remember:
- Spring: Around the October long weekend
- Summer: Around Australia Day
- Autumn: Around the Easter long weekend
If you’re using a liquid fertiliser, you can apply it more often — about once a month during the growing season or when your lawn shows signs of needing a boost.
