Scotts Lawn Builder™ Extreme Green Lawn Fertiliser

Australia's most popular lawn fertiliser has an excellent reputation with home gardeners and professional turf managers alike. This innovative addition to the established range will green your lawn up in just three days

  • Noticeably greener lawns in three days
  • Suitable for all lawns
  • Pet and child friendly
  • Also feeds continuously for up to three months
  • Will not burn when used according to the label directions
  • No surge growth
  • Deeper roots and stronger plants
  • Thickens lawns to prevent weeds
  • Superior results compared to traditional lawn fertilisers

Fast greening

Acts quickly because its nitrogen is highly soluble and available to grasses immediately after application and watering in. It also contains boosted iron and magnesium levels to feed and green your lawn

Controlled feeding

The traditional benefits of slow release of nutrients, which eliminate waste through run-off and leaching and prevent burning, are also available from Extreme Green

No surge growth after application

Traditional lawn foods release or 'dump' most of their nutrients within a couple of weeks of application, causing a rapid surge in growth that quickly drops off again as the food supply diminishes. Scotts Lawn Builder™ uses patented time-release technology to ensure nutrients are released slowly and continuously over a three month period


Extreme Green is has less that 0.5% phosphorus, which means it can be safely used anywhere in Australia without posing any risk to ground or surface water

Low application rate

The recommended application rate is just 16 grams per m2, not the kilograms often associated with regular lawn foods! One bag of Extreme Green is equal to three or more bags of traditional fertiliser

Pet & child friendly

When used as directed, this product is safe to use around domestic pets and children. Check paws and feet for granules before allowing pets or children on to paved areas as staining may occur. 


4kg bag

Suitable for

All lawn grasses including all named varieties of buffalo, traditional couch, Santa Ana couch, kikuyu, bent, fescues and carpet grass

All grass substitutes such as dichondra (also known as pennywort or kidney weed), lippia, zoysia

Not suitable for

Scotts Lawn Builder™ is not recommended for use on plants other than lawn grasses and lawn substitutes

Do not use on lawns less than 8 weeks old - from germination of seed or installation of instant turf (use Scotts Lawn Builder™ Seed & Turf Starter)

Do not use if the temperature is expected to exceed 30 degrees C - wait for a cool spell

How it works

  • Scotts Lawn Builder™ is a slow release fertiliser that provides continuous nutrition over a three month period
  • Every granule of Extreme Green contains Scotts patented time-release nitrogen as well as fast release, readily soluble nitrogen for rapid greening
  • Nutrients are released at about the same rate that grass roots can take up the fertiliser so there is no wastage, run-off to waterways or damaging surge growth

How to use

How much will I need?
Extreme Green has a recommended application rate of 16g/m2.
To work out how much you will need to fertilise your lawn:

  1. Calculate the area of the lawn in square metres (multiply the length by the width)
  2. The area multiplied by the application rate will give the exact amount of Scotts Lawn Builder™ you need
  3. Use a set of scales to weigh it out and then add it to the spreader ready to apply - do not be tempted to add a 'bit extra for luck' because over-application may result in nitrogen burning

    As a guide:
    ¼ of a tennis court is about 65m2
    ½ of a tennis court is about 130m2
    An entire tennis court is about 260m

How do I apply it?

  1. For best results ALWAYS use a Scotts spreader
  2. Check your model and make sure to set it correctly before you start (settings are also on the back label of the product)

    EvenGreen Drop Spreader - setting 4
    EasyGreen Rotary Spreader - setting 25
    HandyGreen or Easy Handheld Spreader - setting 4

  3. If you don't have a spreader, make sure you distribute the fertiliser evenly over the lawn - uneven applications may result in 'hot spot' burning where too much has landed in one spot
  4. Moisten the lawn before applying
  5. Using your spreader, apply half the required amount walking in one direction (eg north - south), then apply the remainder at 90 degrees (eg east-west)
  6. Wait for 24 hours, then water in thoroughly - granules start working with moisture

When to use

  • Extreme Green can be applied at any time of the year for rapid greening - it is not season-specific.
  • For best results, feed your lawns three times a year - in early Spring, early Summer and Autumn.
  • Avoid feeding lawns in cooler regions in Winter.
    • The release of nutrients from granules is controlled by temperature.
    • In Winter when soil temperatures are low and lawn growth is extremely slow in many areas, the granules will simply 'sit' there.

Safety Information

IMPORTANT: This product, when wet, may cause iron stains. Be sure to sweep all granules off paths, coping, paving, diveways, shoes, etc immediately after use. Do not allow the granules to come into contact with these surfaces when they are wet.

Store safely out of the reach of children and pets. This product contains iron which can be harmful to dogs' livers if eaten in quantity.
