What is UltraGrow?

ULTRAGROW SOILS

We’ve changed the game by redefining the soil and potting market

From the very beginning in 1986 Centenary Landscaping Supplies has focused on supplying the very best range of soils. It was then I developed our first blended soil known as Special Blend Garden Soil. At that time, Special Blend was so different to anything available on the market it became a top seller while I was advised no one would buy it. Once again in 2018, we are working diligently with topsoil suppliers and manufacturers, soil scientists and industry professionals to expand our range and set new standards with waste-free soils and potting mixes.

Choosing a good soil is fundamental as it will make up the foundation of your landscaped gardens for many years to come. After spending hundreds or thousands of dollars on plants or turf it’s essential to ensure that your investment is protected with the best possible start. Now you can choose from our new UltraGrow Collection of exceptional science-based landscape soils and growing media free of liquid & green waste. This UltraGrow Collection is unique to Centenary and uncompromised in quality and performance so you can be confident that the soil you choose will really work.

Soil is the absolute foundation to a good garden that you and the community can be proud of. If plants are the crowning glory of a sustainable built environment they simply need good soils or growing media to nurture them to full potential.

ULTRAGROW SPECIAL BLEND TOP DRESSING

Special Blend Lawn Top Dressing was out first successful attempt at making better soil mix back in 1987 when only ‘rubbish’ soils were available in the market and still are. It could be argued that little has changed.  The current Special Blend formula, though paying homage to the original product, is now certified and is far superior to any top dressing both past and present.

This top dressing is a light sandy loam from the same source as Valley Natural but it’s been processed through a 6mm screen making it one of the finest 80% soil-based top dressings on the market. It’s blended with 20% of our certified Enviro Humus-Compost to add carbon and natural nutrients passing AS4419 (2018) 

It can be used as a robust soil for under and over turf or as a finely 6mm screened garden soil.  Boost performance of this product through the addition of a quality fertiliser such as Restore or Organic Extra before application at around a 50mm depth.

Special Blend Top Dressing Contains:

  • 6mm screened natural top soil,
  • Enriched humas compost (Certified AS-4454).

Are you planting in large containers or pots? You’ll need to use an AS 3743 spec product. Check out our UltraGrow Potting & Container Mix Range.
