Nothing is worse than walking down the garden aisle wondering, "How many bags do I truly need?" Whether you're starving a weary lawn or fertilizing your flower beds, guessing can lead to waste or spotty results. This Fertiliser Application Rate Calculator takes the maths out of your hands.
Simple Maths, Better Results
Just enter your lawn area, the fertiliser’s recommended rate (in g/m² or kg per 100m²), and the bag size. In a second, you’ll know exactly how much product to buy and apply. No overdoing it, no underfeeding, just the right amount for strong, green growth.
Why It Matters
Overfertilizing not only costs a lot, but it harms your lawn and puts nutrients into the environment. Under fertilize, and your grass never reaches full lush potential. This device helps you find the sweet spot, giving your lawn just the right amount of shot in the arm without depressing your wallet or the environment.
