Scotts Lawn Builder™ Plus Organics has the best of both worlds - slow-release lawn fertiliser with the added benefits of organics. It's an all-purpose lawn food that promotes lush, green lawns by creating a balanced and sustainable growing environment above and below the soil

When to use



  • Contains composted manure, seaweed, fish extracts and biostimulants to improve soil quality and lawn vigour
  • Slow-release of nutrients eliminates waste through run-off and leaching and prevents burning and surge growth
  • 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
  • Plus Organics is fortified with iron to promote lush green lawns
  • Improves water retention in the soil and helps roots absorb nutrients faster and more efficiently. Better moisture penetration and retention aids in drought-proofing your lawn.


  • Safe to use on all lawns including buffalo, couch and kikuyu
  • Also safe to use on grass alternatives such as dichondra (also known as pennywort or kidney weed), lippia, zoysia


  • Scotts Lawn Builder™ Plus Organics is not recommended for use on plants other than lawn grasses and lawn substitutes
  • Do not use if the temperature is expected to exceed 30 degrees C or when lawns are stressed and the soil is dry


  • Scotts Lawn Builder™ Plus Organics is a slow-release fertiliser that provides continuous nutrition over a two month period
  • Plus Organics contains Scotts patented time-release nitrogen as well as organic nitrogen
  • 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 much will I need?

Plus Organics has two recommended application rates:

  • Good results - apply at 36g/m2
  • Best results - apply at 45g/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 accurately - do not be tempted to add a 'bit extra for luck' because over-application may result in nitrogen burning
As a Guide m2
1/4 Tennis court 65
1/2 Tennis court 130
Full Tennis court 260

Make sure you distribute the fertiliser as evenly as possible over the lawn - uneven applications may result in 'hot spot' burning where too much has landed in one spot. We do not recommend using a fertiliser spreader to apply this product because it may clog and/or damage the spreader

  1. Water in thoroughly after application
  2. If using to improve the soil before sowing or laying a new lawn, spread evenly over the area at the rate of 4.5kg per 100 square metres and then mix it into the top 10cm of soil
