How do I measure my lawn?

Search for your address or use My Location to find your property on the satellite map. Click Start Drawing, then click points around the edge of your lawn to trace its shape. Click the first yellow dot or Finish Drawing to complete the shape. The tool calculates your area automatically and works with any shape including L-shapes and irregular borders.

How much fertiliser do I need for my lawn?

The amount of fertiliser you need depends on your lawn size and the product being used. As a general guide, most granular lawn fertilisers are applied at 30g per square metre. Use the iGrow Carpet lawn measurement tool to draw your lawn and get a personalised recommendation based on your actual area.

What fertiliser should I use in spring?

In spring (March to May), use a fertiliser with higher nitrogen content to encourage growth after winter dormancy. iGrow Carpet Spring Starter Plus is designed specifically for this, applied at 30g per square metre.

What fertiliser should I use in autumn?

In autumn (September to November), switch to a low-nitrogen, high-potassium fertiliser to harden the grass and strengthen roots before winter. iGrow Carpet Autumn Lawn Builder is formulated for this purpose, applied at 30g per square metre.

Can I fertilise my lawn in winter?

Yes, a light winter feed at a reduced rate of 20g per square metre can help maintain lawn health through the colder months. iGrow Carpet Autumn Lawn Builder can be used at this reduced winter rate between December and February.
