Super Green Controlled Release Fertiliser
A controlled release of nutrients to feed your lawn over 10-12 weeks. Your Lawn: Greener, Thicker, Better.
Description
Landscape Range Super Green Controlled Release Fertiliser
N:P:K: 22 : 3 : 4 Controlled Release Lawn Fertiliser.
Super Green feeds your lawn slowly and steadily for 10 to 12 weeks from a single application. Instead of a quick hit, the nutrients are spoon-fed to your lawn over time, so you get consistent growth and colour with fewer applications.
The result is a greener, thicker lawn that leaves less room for weeds to establish.
Suitable for all lawn types, including Buffalo, Kikuyu, Couch, Ryegrass, Kentucky Bluegrass, Fescues and Bentgrass.
Please note: This fertiliser cannot be sent to Western Australia. WA customers can view our Nitro-Green with Iron Boost Fertiliser instead.
Better for your lawn. Better for the environment.
Because the nitrogen is released gradually, less of it washes away before your lawn can use it. That means less nutrient run-off into drains and waterways, and more of what you apply goes into your lawn.
What's in it?
Nitrogen (22%) drives leaf growth and deep green colour, released gradually for a steady feed.
Phosphorus (3%) supports strong root development.
Potassium (4%) helps your lawn handle heat, drought, cold and disease.
Why fertilise?
Every time you mow, your lawn loses nutrients, and over time it loses colour and vigour. A regularly fed lawn grows thicker and greener, builds stronger roots, and has better resistance to disease. A dense, healthy lawn also crowds out weeds naturally and recovers faster from wear and tough weather.
The 3-feed program
Because each application lasts up to 12 weeks, three feeds a year cover your lawn through its main growing periods:
Spring (around September): Fuels fresh growth as your lawn comes out of winter, and keeps feeding it right through spring.
Summer (Early December): Keeps your lawn fed and strong through the heat, without the surge of growth a quick-release fertiliser can cause.
Autumn (around March): Helps your lawn recover from summer and carries it into the cooler months in good health.
Which size do I need?
At the recommended rate of 3kg per 100m², each bag covers approximately:
Bag Size Covers (one feed)
- 5kgs covers 165m²
- 20kgs covers 665m²
Planning a full year? Three feeds use about 9kg per 100m² of lawn each year. A 20kg bag covers the full year's program for lawns up to about 220m².
How to apply
- Apply 3kg per 100m² to a dry lawn.
- For best results, use a broadcast fertiliser spreader. It spreads the granules evenly and avoids burning your lawn.
- Water in well straight after applying.
- Sweep any granules off paths and driveways back onto the lawn.
- Wait 24 to 48 hours before mowing.

Frequently Asked Questions
How often should I fertilise with Super Green?
Three times a year, in spring, summer and autumn. Each application feeds your lawn for 10 to 12 weeks.
What does "controlled release" mean?
The nutrients are released gradually over time rather than all at once. Your lawn gets a steady supply of food for up to 12 weeks, instead of a quick boost.
Should I choose Super Green or All Seasons?
Both are high in nitrogen and suit all lawn types. Super Green feeds steadily for up to 12 weeks, so you only need three applications a year. All Seasons Fertiliser gives a fast colour boost and is applied four times a year. If you want fewer applications and a consistent, even feed, choose Super Green.
Can I use it on new turf?
Yes. Super Green is recommended for newly laid instant turf to help it establish after installation.
Can I apply it in summer?
Yes, apply it early in Summer Avoid applying when the temperature is over 30 degrees, during a heatwave or when your lawn is drought stressed, and always water in well.
How do I apply it?
You can apply Super Green by hand, but using an Earthway Spreader is easier and gives a more even application, which means a more even green across your whole lawn and less risk of burning. See our spreaders here. If you're applying by hand, wear gloves and spread half the fertiliser walking up and down the lawn, then the other half walking across it. This helps avoid patchy spots and missed areas. Whichever way you apply it, water in well straight afterwards.
Will this burn my lawn?
Not when used correctly. Use the recommended rate, apply to a dry surface with a spreader for even coverage, and water in well straight away.
Do I really need to water it in?
Yes. Watering in settles the granules into the soil around the roots so the nutrients can start working, and it prevents leaf burn. If good rain is forecast within a few hours, you can apply just before it.
Is it safe for kids and pets?
Once it's been watered in well and the lawn has dried, it's safe for your family and pets to use the lawn again. Keep kids and pets off the lawn while you're applying, and store the bag out of their reach.
When can I mow?
Wait 24 to 48 hours after applying before you mow.
Can this be sent to WA?
No, sorry. Western Australia restricts phosphorus levels in fertiliser, and Super Green is above their limit. Our Nitro-Green with Iron Boost Fertiliser can be sent to WA.
