How it Works
The Science Behind Roots, Shoots and Leaves Fertiliser:
Roots, Shoots & Leaves is a controlled-release, mineral-based fertiliser designed to optimise nutrient use efficiency (NUE), soil structure, and sustained plant growth across a wide range of systems. Its formulation combines readily available nitrogen with stabilised nutrient sources and mineral amendments to support both immediate plant response and extended feeding over time.
The granular delivery system provides a staged nutrient release, reducing volatilisation and leaching losses while maintaining a consistent supply of nutrients within the root zone. This is further supported by mineral components such as zeolite, which enhance cation exchange capacity (CEC) and improve nutrient retention in the soil profile. In addition, the inclusion of natural wetting agents and biologically supportive inputs improves moisture distribution and microbial activity, contributing to better nutrient mobility and rhizosphere function. These interactions promote improved soil aggregation, aeration, and water-holding capacity, creating a more stable environment for root development.
The overall effect is consistent vegetative growth, improved canopy development, and enhanced plant resilience, particularly in systems requiring sustained nitrogen supply. Designed for integration into standard fertiliser programs, performance will vary depending on soil type, organic matter levels, and environmental conditions.
In summary:
- High nitrogen content (16%) supports leafy growth & chlorophyll production
- Slow-release potassium (10%) aids in root health, flowering and drought resistance
- Trace elements like iron, zinc, manganese, boron, and copper improve plant immunity and vitality
- Added silica and sulphur improve structural strength and nutrient absorption
- Natural wetting agents improve growing media and soil penetration
- Zeolite reduces leaching and enhances CEC (cation exchange capacity)

FAQ
What is Roots, Shoots & Leaves fertiliser?
Roots, Shoots & Leaves is a slow-release granular fertiliser with a 16-2-10 NPK ratio, designed for Australian lawns, gardens and plants. It provides balanced nutrition, trace elements and soil-enhancing minerals to support strong root development, healthy growth and long-lasting plant performance.
What does a 16-2-10 NPK fertiliser mean?
The 16-2-10 NPK ratio means the fertiliser is high in nitrogen (16%) for lush green growth, with phosphorus (2%) to support root development and potassium (10%) for plant strength, drought resistance and overall health. This balance makes it ideal for lawns and leafy plants.
What plants can I use Roots, Shoots & Leaves on?
This granular fertiliser is suitable for lawns, vegetable gardens, shrubs, fruit trees, ornamentals and potted plants. It’s a versatile all-purpose fertiliser designed to support plant growth across a wide range of applications.
Is this fertiliser suitable for lawns like buffalo, couch and kikuyu?
Yes, Roots, Shoots & Leaves is safe for all common Australian lawn types including buffalo, couch and kikuyu. It promotes greener colour, stronger root systems and improved turf resilience without excessive growth surges.
How long does this fertiliser last in the soil?
Roots, Shoots & Leaves uses slow-release technology to feed plants for several months. This provides consistent nutrition over time, reduces nutrient loss through leaching and supports steady plant growth. :contentReference[oaicite:1]{index=1}
What are the benefits of slow-release granular fertiliser?
Slow-release fertilisers deliver nutrients gradually, improving efficiency and reducing waste. They provide longer-lasting results, reduce the risk of nutrient burn, improve soil health and minimise environmental runoff compared to quick-release fertilisers.
Does this fertiliser improve soil health?
Yes, Roots, Shoots & Leaves contains trace elements, silica, sulphur and zeolite, which help improve soil structure, increase nutrient retention and support beneficial microbial activity in the soil. :contentReference[oaicite:2]{index=2}
What role does zeolite play in this fertiliser?
Zeolite helps reduce nutrient leaching and improves cation exchange capacity (CEC), allowing the soil to hold onto nutrients more effectively and make them available to plants over time.
Does this fertiliser contain trace elements?
Yes, it includes essential trace elements such as iron, zinc, manganese, boron and copper. These micronutrients support plant immunity, chlorophyll production and overall plant health. :contentReference[oaicite:3]{index=3}
Can I use this fertiliser in pots and containers?
Yes, Roots, Shoots & Leaves is safe for use in pots and container plants. It provides steady nutrient release and helps maintain healthy growing media without rapid nutrient depletion.
Is this fertiliser suitable for Australian soils?
Yes, this product is specifically designed for Australian soil conditions. It includes ingredients that improve water penetration, nutrient retention and soil biology in challenging environments such as sandy or nutrient-poor soils. :contentReference[oaicite:4]{index=4}
Can I use this fertiliser with liquid fertilisers?
Yes, granular fertilisers like Roots, Shoots & Leaves work well as a base fertiliser and can be combined with liquid fertilisers or soil conditioners to enhance nutrient uptake and plant performance.
Will this fertiliser help improve plant growth and colour?
Yes, the high nitrogen content promotes lush green growth, while potassium and trace elements improve plant strength, colour and overall vitality.
Is this fertiliser environmentally friendly?
This fertiliser is designed to be more efficient and environmentally responsible, with slow-release nutrients and zeolite helping reduce nutrient runoff and improve nutrient use efficiency.
