Grass Seeding
When it comes to landscape soils, one name stands out for its commitment to excellence and performance: BENEDICT SAND & GRAVEL. With our SmartMix® range of products, we have revolutionised the industry by combining a sound scientific basis with superior structural integrity. Each of the eleven SmartMix® products is meticulously engineered to outperform competitors’ products, providing long-term results that continue to improve with age. In this article, we delve into the scientific principles that underpin the SmartMix® soil range, highlighting its innovative approach and benefits across various applications.


Unlike many other commercial landscape soils, SmartMix® products prioritise the critical air/water balance within a soil. We achieve this by incorporating specifically selected mineral materials that form a robust structural framework. This framework creates macropores, which are essential for proper air circulation and water movement within the soil, and enable better root penetration, nutrient uptake, and ultimately overall plant growth. We call this our Benedict RootLover Technology®. To complement the structural framework, we blended high-quality horticultural ingredients into our SmartMix® products. These ingredients include reactive clays and organic matter, both of which contribute to soil fertility, moisture retention, and nutrient availability. By carefully selecting and incorporating these ingredients, we ensure that the soils in our SmartMix® range provide the ideal environment for plants to thrive.

Recognising that different plant species have varying needs, we developed SmartMix® products tailored to specific requirements.

The SmartMix® soil range caters to a wide array of applications, ensuring there is a suitable product for most landscaping needs. For areas under turf, SmartMix® 1 and SmartMix® 2 are specialised soil mixes that resist compaction, provide rapid drainage, establish a strong root system, and promote sustained healthy grass growth. In pavement areas with trees, the award-winning Benedict SmartMix® 3 provides optimum conditions for tree growth, preventing root heaving and pavement damage. Planter boxes and rooftops benefit from the SmartMix® 4 and SmartMix® 5 ability to maintain optimum moisture whilst still being free draining. Critically, SmartMix® 4 and SmartMix® 5 are lightweight soils that are non-slumping, providing a stable growing environment for plants.

Recognising that different plant species have varying needs, we developed SmartMix® products tailored to specific requirements. For phosphorus-sensitive plants, SmartMix® 6 and SmartMix® 7 are dedicated soil mixes formulated to limit phosphorus availability, ensuring the healthy development of these species.

SmartMix® soils also find their place in water-sensitive urban design applications such as biofiltration basins, rain gardens, retention basins, and wetlands. These specialised soil blends assist in water management, filtration, and assist in promoting sustainable urban environments.


When it comes to long-term performance, SmartMix®  products are unrivalled in the industry. Our commitment to engineering soils that improve with age sets us apart from our competitors. While many landscape soils deteriorate over time, SmartMix® products continue to provide structural support, ensuring sustainable growth and stability. With the SmartMix® range, landscape installations are built to last, reducing the need for costly replacements or amendments.
