    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
  • SLOW-RELEASE of nutrients eliminates waste through run-off and leaching and prevents burning
  • TRADITIONAL LAWN foods release ('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
  • PREMIUM is phosphorus-free, which means it can be safely used anywhere in Australia without posing any risk to ground or surface water
  • PREMIUM has a recommended application rate of just 16 grams per square metre, not the kilograms often associated with traditional lawn foods! One bag of Premium is equal to three or more bags of traditional fertiliser of the same weight
