Pro-Kleen 4-in-1 lawn fertiliser has been specially formulated with nitrogen, phosphorous, potassium and added 2% magnesium oxide. This formula has low levels of fast and slow-release nitrogen that encourage strong shoots to develop, making sure your lawn grows robust and healthy. Phosphorous encourages strong root development so that each blade of grass grows thick and healthy. Potassium is a key ingredient in preventing lawn disease and keeping your lawn healthy during the cold autumn and winter. Magnesium is an essential element of plant growth, although it is often missing in other lawn fertilisers. It helps to keep chlorophyll levels high, which prevents poor and stunted plant growth. This lawn feed contains no harsh chemicals, meaning that children and pets can be reintroduced to the area after application. The lawn granules are also non-staining and won’t leave any brown stains on your decking, patios or driveways, so you can use them with complete peace of mind. Pro-Kleen’s Pre-Lawn and Seed Starter Fertiliser helps to boost root development so that your grass gets the best start possible. It lasts up to three months after application to make sure your grass grows strong, healthy and vibrant! These 2.5kg tubs can cover up to 70m2-100m2. Application Rate: 25-35 g/m². Apply 3-5 days before seeding or laying turf or up to 6 weeks afterwards. You can apply Pro-Kleen’s Pre-Lawn and Seed Starter Fertiliser by hand or by using a garden spreader. For best results, keep the area well-watered after laying turf or sowing lawn seed.
