  • Contains Scotts Osmocote® controlled release fertiliser and growth stimulants to supply plants with all the nutrients they need
  • Includes a wetting agent that allows water to soak in and prevents drying out
  • Ideal for all plants
  • Feeds for 4 months continuously

Growth stimulants

Encourage strong root development leading to healthier, more vigorous plants

Wetting agent

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

Australian Standard

Certified to meet the Australian Standard for Premium potting mixes

Soluble nitrogen

This mix contains a higher level of more readily available soluble nitrogen than regular mixes. While it contains a balanced fertiliser, additional feeding may be required depending on the nutrient demands of plants being grown in it.


25L and 50L bags

Suitable for

Indoor and outdoor plants, shrubs, flowers, palms, fruit trees, vegetables and herbs - an all-round all purpose mix

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 or ponds

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

How it works

  • Premium provides the ideal moisture and nutrient environment for healthy, strong and productive plants.
  • It has been designed and is guaranteed to grow better plants from potting to flowering or fruiting

How to use

  1. Use Premium Mix straight from the bag - don't mix it with other materials. Close the bag tightly after use
  2. Water each plant well an hour or so before repotting, and leave to drain
  3. Choose a clean container with large drainage holes and partly fill it the fresh mix out of the bag
  4. Carefully lift the plant to be potted up from its existing pot. Gently loosen the old mix around the root ball without disturbing roots too much and remove any damaged, twisted or dead roots
  5. 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
  6. Fill in with Premium Mix to within 2-3cm of the top rim of the pot and press lightly
  7. 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
  8. 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.
  9. 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

When to use

  • Potting mixes can be used at any time of the year.
  • Repotting established pot plants is best done either in Spring or Autumn - avoid Winter or Summer as the extremes of temperature may stress plants
  • Flowering plants should be repotted after they have flowered - enjoy the blooms first!
