Pro-Kleen Pre Lawn & Seed Starter Fertiliser – 2.5kg

Getting a new lawn off to the right start depends heavily on what's happening beneath the surface, and this granular fertiliser from Pro-Kleen is formulated specifically for that critical establishment phase. With an NPK ratio of 8-12-8, it's notably higher in phosphorus than a standard lawn feed, which encourages strong root development in young grass rather than simply pushing leafy top growth. Added magnesium, zinc, and seaweed extract round out the nutrient profile, giving seedlings and freshly laid turf everything they need to anchor in and thrive.

It's designed to be worked into the soil three to five days before you sow seed or lay turf, though it remains effective if applied up to six weeks after — useful if you've already started and want to give things a boost. At a recommended rate of around 25–35g per square metre, a 2.5kg tub will comfortably cover up to 83 square metres, making it well suited to a typical garden lawn project. Application is straightforward whether you're spreading by hand or using a rotary spreader, and watering in afterwards helps the granules get to work quickly.

The formula is non-toxic and child and pet friendly once applied, which is reassuring if your garden is a busy one. It's also non-staining, so you won't need to worry about granules straying onto nearby paving or decking. This is a solid choice for anyone laying turf or overseeding from scratch who wants to give their grass the best possible foundation from day one.
