A premium quality potting mix specially formulated for roses and other plants that prefer acidic growing conditions, such as gardenias, camellias, azaleas, rhododendrons, magnolias and pieris. It includes Scotts Osmocote® that feeds for months

When to use



  • An acidic mix designed specifically for plants that require soils of pH 6 or less to thrive (pH 7 is neutral and over 7 alkaline)
  • Boosted levels of iron and magnesium produce lush, deep green leaves and help eliminate yellowing and premature drop of flower buds before they open
  • Wetting agent assists moisture to soak into the mix and helps roots absorb nutrients
  • Certified to meet the Australian Standard for Premium potting mixes


  • All trees and shrubs that need acidic soil or potting mix in which to thrive and flower well. These plants resent clay soils and will suffer significantly if lime is applied around their roots
  • Acid lovers include blueberries, conifers, hydrangeas, foxgloves, primroses and lupins as well as those plants already mentioned
  • Safe to use for new plants - the controlled release of nutrients means it will not burn soft leaves or tender young roots


  • Plants that grow best in neutral to alkaline soils and potting mixes, including crabapples, mock orange, robinias and viburnums
  • Don't use in hydroponic growing systems or ponds
  • Don't use on lawns - use only specifically named lawn topdress soils on grassed areas


In pots

  1. Use Rose, Gardenia, Azaleas and Camellia Mix straight from the bag - don't mix it with other materials. Close the bag tightly after use
  2. Water plants that are to be repotted and allow them to drain
  3. Choose a clean container with large drainage holes and partly fill it withfresh mix out of the bag
  4. Carefully knock the plant to be potted up from its existing pot and loosen the root ball. Trim off any dead or damaged roots
  5. Place the plant in the centre of the pot and fill with the mix to 2-3cm below the rim
  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 a sheltered spot for a few days to allow the plant to settle and acclimatise before moving back to its permanent home

In-ground planting

  1. When planting into the garden, dig a dish-shaped hole about 1½ times the size of the root ball of the plant and twice as wide
  2. Turn the plant out of the existing container, loosen the root ball and trim any damaged roots. If the plant has been lifted directly from the ground and is wrapped in hessian, remove it from the wrapping and carefully loosen the rootball as above
  3. Place some Rose, Gardenia, Azalea & Camellia Mix in the base of the hole, then position the plant in the centre. If planting out bare-root roses in winter, prepare the planting hole as outlined but create a mound of the mix in the base and then spread the roots out over it
  4. Once positioned, backfill the planting hole with mix and ensure the plant is no deeper than it was previously either in a pot or in the ground (check the soil mark on the trunk)
  5. It is important that any budding or grafting union is well clear of the soil level as it is often a weak point through which diseases and pests can enter the plant
  6. Water the plant well after planting and make sure it is not allowed to dry out in the first few weeks
