TerraCottem Universal is the 'original' TerraCottem soil conditioner. Since it was launched in 1993, the product has constantly evolved with better performing polymers, fertiliser and carrier material to further enhance root and plant growth and reduce inputs. This is still the TerraCottem to use in most applications such as trees, shrubs, revegetation, annuals, perennials, roof gardens, horticulture and potting soils.

How does it work?

The TerraCottem soil conditioners are a proprietary mixture of more than twenty components each from different groups all assisting in the plant growth processes in a synergistic way:

  • Growth precursors or biostimulants

  • Cross-linked hydro-absorbent polymers or hydrogels

  • Specially selected fertilizers

  • Carrier materials

TerraCottem works at root level

TerraCottem is a potent, dry, granular product. You mix it in small quantities with the soil. That’s where the action takes place, at root level. It’s important to get good root development from the very start. That’s how you lay the foundation for thriving and lasting plant growth.

TerraCottem is activated by watering the plant

Compare it with charging a battery. Once charged, the "magic" starts. The hydro-absorbent polymers or hydrogels contained within TerraCottem start to swell upon contact with water. They absorb water and nutrients and expand into a gel-like substance. And oh, correction: better compare TerraCottem with a rechargeable battery as the soil conditioner will have numerous dry / wet cycles during a period of 8 years.

The polymers absorb the water and fertilisers

Water and nutrients are absorbed at root level by the hydrogels. In soils with low water retention, that water and part of the nutrients would normally be lost to leaching and evaporation.

  100g of TerraCottem can be "charged" with over 5 litres of water!

This water is then kept at the disposal of the plant that accesses the stored water on demand through its root hairs, keeping the water in the root zone for a longer period of time. As such, both the volume and frequency of necessary irrigation can be reduced up to 50%.

As said earlier, the hydrogels also absorb nutrients within that soil solution. TerraCottem's specially selected fertilisers provide a balanced nutrition of both macro and micro-elements to the plants.

The growth precursors encourage root hair growth

These root hairs grow inside the polymers and absorb the required amount of water and nutrients. The growth precursors play a very important role in the initial growth phase of the plant. They are TerraCottem’s trade secret. They are but a fraction of the product – 0.25% to be precise - but potent and crucial for plant growth! These biostimulants activate root cell elongation and differentiation. In other words, they stimulate the plant to grow more and longer roots, faster. The bigger and healthier the root system, the bigger and healthier the plant.

In addition, roots are encouraged to grow more rapidly to depths where more water is present.


Arborgreen has created a streamlined freight policy for customers Australia wide. Note: as of the 8th of September 2021 we have slightly increased our standard freight charge due to rising freight costs.

  • All orders over $400.00 +GST it will be delivered free of charge (ensuring that the goods you have purchased are not bulky^)

Stock Control & Pricing Breaks

Our webstore now indicates an approximate level of items in stock. This is indicated as quantity breaks as follows: 1+, 6+, 12+, 36+, 100+, 250+, 500+, 1000+, 2000+ and 3000+. For example: if we have 5 ARS Florist Scissors in stock this would display as 1+ — if there are 47 in stock it will indicate 36+. As another example: if we have 14,960 Fluted Tree Guards in stock this would indicate as 3000+. The quantity also indicates the number of items as described by the product description; so Florist Scissors are sold individually whereas the 10L Carton Tree Guard is sold in boxes of 150 – in the later case 100+ items refers to 100+ boxes of 150 (or over 15,000 Carton Tree Guards in stock).

Please note: our webstore stock levels are accurate to within the last hour; if you order an item that has since sold out, we will promptly notify you as to when your order will be fulfilled. Some items may be indicated as Special Order items or display a custom message as to when stock is due.

Pricing breaks: many items in our store display pricing breaks. The number of items indicated in pricing breaks can vary a lot between different products. Often with horticulture tools such as secatuers and loppers, the pricing breaks may relate to the number of items in a box or total number of items in a carton; so if you need several secateurs, and order per box or carton, you save more as we save time packing your order. Items such as tree guards, bamboo canes and hardwood stakes often have price breaks set to fill a standard palette size; thus savings or efficiency gains are made in the storage and transport of these items.
