What it does

Soil Boost is a powerful soil-conditioning fertiliser designed to strengthen your lawn from the ground up. It promotes root growth, improves water and nutrient uptake, and builds resilience during high-stress periods like summer heat.

This advanced formula uses a combination of nitrogen, organic acids, and beneficial fungi to support a healthier, stronger lawn — especially when it’s under pressure.


Key benefits

  • Nitrogen (6%) – Fuels steady, balanced growth
  • Natural plant acids – Unlock nutrients in the soil and improve iron and phosphorus availability
  • Beneficial fungi (VAM) – Extend the root system to boost water and nutrient absorption
  • Plant hormones and microbes – Stimulate root development and convert nutrients into forms your lawn can use


When and how to apply

  • Mix 200–400ml with 4 to 5L of water per 100m²
  • Apply using a backpack or knapsack sprayer for even coverage
  • Safe for new lawns after the first mow
  • Water in lightly if no rain is expected within 24 hours

✅ Safe for all NZ grass types including ryegrass, fescue, kikuyu and couch
🐾 Pet-safe once dry
