Help your lawn wake up from winter with steady, vibrant growth this spring
iGrow Carpet's slow-release spring fertiliser helps you grow a rich, green, thick lawn with ease. It releases nutrients slowly, providing sustained and controlled results for up to 3 months. This means your lawn gets the right amount of nourishment over time. With iGrow Carpet, lawn care is made easy, so you can enjoy a healthy lawn with less effort!
Our Spring starter gives your lawn a proper boost to kick start the growth as the days lengthen and the temperature starts to rise.
Nitrogen (20% N) - boosts the lawn and will help it turn into a lush green carpet as the days start to get longer. Nitrogen is crucial for photosynthesis and overall plant health.
Phosphorus (4% P) - Helps kick start root growth, giving them the energy to push deeper into the soil.
Potassium (10% K) - Is important for a lawn as it vital for root growth, it helps your grass withstand temperature fluctuations and makes it more resilient to diseases, pests and drought
Magnesium (2% MgO) is central to chlorophyll production (in simple terms), this helps your lawn achieve a darker richer shade of green. Without any staining that comes with cheaper products
Calcium (4% CaO) helps the rest of the nutrients all work better together and stops the nutrients getting locked up in the soil, it also helps regulate soil PH
Use our Measure Your Lawn Tool — to calculate how many bags you need in total.
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.
