Growth stimulants

Encourage strong root development leading to healthier, more vigorous plants


A renewable resource that replaces traditional peat in potting mixes

Water crystals

Non-toxic crystals that hold up to 100 times their own weight of water

Wetting agent

Assists moisture to soak into the mix and helps plant roots absorb nutrients

Australian Standard

Certified to meet the Australian Standard for Premium potting mixes


10L, 25L and 50L bags

Suitable for

Indoor and outdoor plants, shrubs, flowers, palms, fruit trees, vegetables and herbs

Can be used in pots that will be submerged in ponds but make sure the mix is covered with a 2-3cm layer of coarse washed sand or pebbles to prevent it floating out of the pot and contaminating water

Safe to use on new plants - the controlled release of nutrients means it will not burn soft leaves or tender young roots

Not suitable for

Don't use in hydroponic growing systems

Don't use on lawns - use only specifically named lawn topdress soils on grassed areas

How it works

  • Premium Plus provides the ideal moisture and nutrient environment for healthier, stronger and better quality plants.
  • It has been designed and is guaranteed to grow better plants from potting to flowering or fruiting

How to use

  1. Use Premium Plus Mix straight from the bag - don't mix it with other materials. Close the bag tightly after use
  2. Choose a clean container with large drainage holes and partly fill it the fresh mix out of the bag
  3. Carefully lift the plant to be potted up from its existing pot. Gently loosen the root ball without disturbing roots too much and remove any damaged, dried out or twisted roots
  4. Place the plant in the centre of the pot (if potting up individually) or position it where you want it grow in a larger container that will eventually hold several plants
  5. Fill in with Premium Plus to within 2-3cm of the top rim of the pot and press lightly
  6. Tap the new pot or container gently on the bench to help the new mix settle in and around the roots - do not pack it down
  7. Water the pot thoroughly (until water runs from the drainage holes) then allow it to drain freely. If necessary top the mix up again to the suggested level.
  8. Place the pot or container in the shade for a few days to allow the plant to settle and acclimatise before moving back to its permanent home
