Neutrog Sudden Impact for Lawns + POPUL8 20kg – Organic-Based Lawn Fertiliser for All Lawn Types

Neutrog Sudden Impact for Lawns: Organic-Based Fertiliser for Greener, Thicker Turf

Neutrog Sudden Impact for Lawns is an organic-based, nutritionally boosted granular fertiliser made for new and established lawns of all types, including Buffalo. Its organic base releases a full range of nutrients slowly, while added water-soluble nutrients give a faster green-up after each application. The granules are coated with POPUL8, Neutrog's advanced soil biological formula, and a 20kg bag covers up to 400m² of established lawn.

Quick Green-Up and Slow Feeding in the One Granule

Sudden Impact combines two approaches that most lawn fertilisers keep separate. The water-soluble nutrients get to work soon after watering in, bringing colour back to tired turf, while the organic base keeps releasing nutrients over the following weeks. That balance helps lawns thicken up, recover from stress and correct nutrient deficiencies without the harsh surge-and-crash of a purely chemical feed.

What POPUL8 Adds to Your Lawn

Each granule is coated with POPUL8, a blend of more than 240 beneficial bacteria and fungi. These microbes help release nutrients in the soil so grass can use them, support disease suppression and encourage growth. Together with boosted levels of iron and magnesium, which are key to chlorophyll production, this helps lawns develop a deep, even green colour and healthier soil underneath.

More Than a Lawn Food

Because it is high in nitrogen and potassium and low in phosphorus, Sudden Impact for Lawns also suits other non-flowering plants that are grown for their foliage. It is a good feed for hedges, palms, ferns, conifers, leafy vegetables and herbs, making it a versatile bag to keep in the shed.

Tips for the Best Lawn Results

Spread the granules evenly, going over the lawn in two directions at half rate each for even coverage and no patchy green stripes. Mow a day or two before feeding rather than straight after, and water in thoroughly so the granules settle into the soil. Avoid applying during the hottest part of a summer day. For small areas, measure by the cup so you stay close to the 50g per square metre rate.
