The application rate is 25–35 grams per m².
30 grams per m² is the recommended average — it gives a great balance of colour, growth, and coverage, while allowing for a bit of wastage or overlap around edges.
We currently offer 2.5kg and 8kg bags. Use the chart below to estimate how much fertiliser you’ll need based on your lawn size and how heavily you plan to apply it.
