When to Use

  • Can be applied throughout the year
  • For optimum results apply from Sep-Apr

  • This pack treats 400sq.m, equivalent to 40 car parking spaces. 1 parking space = 2 x 5 metres = 10sq.m


  • Mark out the areas to be treated
  • Apply the granules thinly and evenly to ensure the same result across the entire lawn
  • Do not exceed the application rate
  • Apply 100-120 grams per square metre over lawns infested with moss

  • If using a wheeled spreader, adjust the setting and calibrate to apply the correct rate. More spreader settings.

To Finish

  • Water granules in well within 48 HOURS if no rain falls to activate the fertiliser
