Neutrog Sudden Impact for Lawns 10kg – Organic-Based Lawn Food for All Lawn Types

Neutrog Sudden Impact for Lawns 10kg: Premium Lawn Food for Smaller Lawns

Neutrog Sudden Impact for Lawns is an organic-based, chemically boosted granular fertiliser developed for new and established lawns of every type, including Buffalo. The 10kg bag covers up to 200m², a practical size for suburban backyards, front lawns, courtyards and townhouse gardens. Beyond the lawn, it also feeds non-flowering plants such as palms, ferns and conifers, along with leafy vegetables and herbs.

The Best of Both Worlds in Every Granule

Sudden Impact for Lawns pairs a slow-release organic base with carefully selected water-soluble nutrients. The organic base supplies a full range of plant nutrients that feed the lawn gradually, while the soluble portion lifts the performance of every application. You get a visible response after watering in, backed by steady feeding in the weeks that follow, the same approach Neutrog uses in its well-known Sudden Impact for Roses.

Iron and Magnesium: The Secret to a Deep Green Lawn

What sets this lawn food apart is the balance of its nutrients. The nitrogen to potassium ratio is set to promote strong, even growth, and the levels of iron and magnesium are deliberately boosted. Both elements are central to forming chlorophyll, the green pigment that lets grass capture sunlight and turn it into energy through photosynthesis. More chlorophyll means richer colour and healthier, more vigorous turf.

Setting Up a New Lawn the Right Way

A new lawn performs best when the soil is fed before the seed or turf goes down. Spreading Sudden Impact for Lawns at the new-lawn rate and working it into the top 10cm of soil gives young roots immediate access to nutrients as they establish. Once the lawn is up and growing, switch to the regular maintenance rate every 6 to 8 weeks.

Getting Even Coverage on Your Lawn

To avoid patchy green strips, divide the granules in half and spread one half walking up and down the lawn, then the other half walking across it. Weigh out 50g once and note how full it fills a cup or scoop, so you can measure quickly each time. Mow a day or two beforehand, apply on a mild day rather than in the heat of summer, and water in thoroughly so the granules reach the soil.
