I used this across the front lawn and the colour deepened nicely over the next week. The grass looks more even and feels a bit thicker when you walk on it. Really easy to apply since it just attaches to the hose. No complaints, will keep using it through the season.

Fe
Iron
Richer, deeper green
Iron supports a richer, deeper green lawn by helping grass produce chlorophyll—the green pigment used during photosynthesis.
- Encourages stronger green colour without relying only on rapid leaf growth.
- Helps improve the appearance of pale, yellowing or tired-looking turf.
- Supports efficient photosynthesis and healthy grass-blade function.
Iron is especially useful when a lawn needs a colour boost or is struggling to maintain a healthy green appearance. It works alongside nitrogen and micronutrients to support balanced lawn nutrition from root to blade.
Good to know: Apply lawn fertiliser according to the label and remove granules or liquid overspray from concrete, paving and other hard surfaces to help prevent staining.
N
Nitrogen
Thicker leaf growth
Nitrogen supports thicker, greener lawn growth and provides grass with an essential nutrient for producing healthy leaves and shoots.
- Encourages dense, vigorous grass-blade development.
- Supports healthy green colour and chlorophyll production.
- Helps turf recover from mowing, foot traffic and general wear.
A steady nitrogen supply helps create a fuller, more uniform lawn. Dense, actively growing turf can also leave less open space for unwanted weeds to establish.
Balanced feeding matters: Lawn Grow combines nitrogen with phosphorus, potassium, iron and micronutrients to support complete lawn growth without relying on nitrogen alone.
P
Phosphorus
Strong root development
Phosphorus supports strong lawn root development and helps grass store and transfer the energy required for healthy growth.
- Encourages strong root establishment and development.
- Supports energy transfer throughout the grass plant.
- Helps roots access available moisture and soil nutrients.
A healthy root system creates the foundation for resilient turf. Stronger roots help grass remain anchored and make more effective use of available water and nutrients.
Good to know: Lawn nutrient requirements vary with soil type, turf variety and growth stage. Always apply fertiliser according to the product directions.
K
Potassium
Greater lawn resilience
Potassium supports lawn strength and resilience by helping grass regulate water and maintain essential internal plant processes.
- Supports efficient water regulation within the grass plant.
- Helps turf cope with heat and changing environmental conditions.
- Contributes to strong, balanced and resilient lawn growth.
Unlike nitrogen, potassium does not primarily drive leafy growth. Instead, it supports the systems that help grass use water and nutrients efficiently.
Combined with nitrogen and phosphorus, potassium helps create a lawn that is not only greener but also better prepared for regular wear and seasonal stress.
Ca
Micronutrients
Ca 0.5%Mn 0.38% Healthy structure + chlorophyll support
Calcium and manganese provide targeted micronutrient support for healthy lawn structure, chlorophyll production and essential plant processes.
- Calcium 0.5%: Supports normal cell-wall structure, healthy tissue development and steady turf growth.
- Manganese 0.38%: Supports photosynthesis, chlorophyll formation and important enzyme activity.
- Complements the primary NPK nutrients for more complete lawn nutrition.
Grass needs micronutrients in smaller quantities than nitrogen, phosphorus and potassium, but they still play an important role in lawn colour, development and nutrient use.
Lawn Grow combines macronutrients and micronutrients in one balanced lawn fertiliser to support greener blades, stronger roots and healthier growth.

FAQ
Most Australian lawns benefit from an application every 2–3 weeks during the active growing season (spring through early autumn). This maintains colour, encourages new growth, and improves lawn density. In winter, when growth slows, reduce to once every 4–6 weeks or pause if your lawn is dormant.
Yes — this lawn fertiliser is formulated for all common Australian turf varieties, including Buffalo (Sir Walter, Palmetto), Kikuyu, Couch (including TifTuf), and Zoysia. The balanced nitrogen and potassium levels support green colour, root strength and stress tolerance across each lawn type.
Most people notice a deeper green colour within 3–7 days, especially due to the inclusion of chelated iron, which supports fast chlorophyll development. Thickness and density improve gradually over 2–4 weeks with consistent watering and regular feeding.
Yes — but wait 3–4 weeks after laying new turf before applying fertiliser. New sod needs time to root into the soil. Once the lawn is anchored and growing, begin with a light hose-on application, then continue every 2–3 weeks throughout the growing season.
