Give your new lawn the best possible start before seeding or laying turf.
iGrow Carpet’s pre-seeder fertiliser is specially designed to prepare your soil and give young grass the perfect boost at the start. It releases nutrients steadily over 4 - 8 weeks, giving new lawns the essential nourishment they need to get going. Because it’s the same size and applied at the same rate as our other products, switching between feeds couldn’t be easier. Just apply before or just after sowing for strong, even results.
Our pre-seeder is ideal before sowing new seed or laying turf, supporting fast root development and even growth right from the beginning.
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.

• We recommend watering the lawn within 48 hours of application. (The sooner it is watered in, the sooner you will see the results).

• Keep pets and the kids off the lawn during application and for a few hours afterwards.
