Lawnporn Launch is specially formulated for the start of growing season, lawns under repair from stress or injury and establishing new lawn. With high nutrient levels we’ve also added the Kelp for biostimulant activity. This is a professional starter and repair fertiliser. As a key nutritional requirement in establishment and root system development, phosphorous is an essential component of Launch, containing 10percent P as phosphite, which provides sustained supply of phosphorus within the soil as it is converted to plant usable phosphate within the root zone. This is given to the root zone at a precise level as avoiding overloading the plant with phosphorous would comprimise uptake of key micronutrients such as iron.
