Australia's most popular lawn fertiliser has an excellent reputation with home gardeners and professional turf managers alike. The 'set and forget' solution to having a great lawn all year round, this product has all the best nutrients to ensure your buffalo lawn has all it needs to flourish

When to use



  • May be safely used on all types of lawn including the buffalo varieties Sir Walter, Palmetto, Sapphire, ShademasterandMatilda, as well as kikuyu and couch varieties
  • Boosted ironcontent promotes deeper greenand stronger growth. The thicker the lawn, the less chance weeds have of taking hold - they're smothered before they become obvious and need treatment
  • Slow-release of nutrients through controlled feeding 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
  • Buffalo has a low 0.5%phosphorus, which means it can be safely used anywhere in Australiawithout posing any risk to ground or surface water
  • Buffalo has a recommended application rate of just 16 grams per m2, not the kilograms often associated with regular lawn foods!
  • 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


  • 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


  • 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 (useScotts Lawn Builder Seed & Turf Starter)
  • Do not use if the temperature is expected to exceed 30 degrees C - wait for a cool spell


  • Scotts Lawn Builder™ is a slow-release fertiliser that provides continuous nutrition over a three month period
  • Every granule of Buffalo contains Scotts patented time-release 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?

Buffalo 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

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)
  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

  • Buffalo is guaranteed to green the lawn within one week of the lawn receiving moisture

Fast Method

  • For fast results apply to moist lawn, wait 24 hours and then water in thoroughly

  • For best results, feed your lawns three times a year- in early Spring, early Summer and Autumn
  • Avoid feeding lawns in cooler regionsin 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


IMPORTANT: This product, when wet, will cause iron stains. Be sure to sweep all granules off paths, coping, paving, driveways, 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.
