Acidic mix

Designed specifically for plants that require soils of pH 6 or less to thrive (pH 7 is neutral and over 7 alkaline)

Iron and magnesium

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

Water crystals

Absorb and hold many times their own weight of water, releasing it back in the mix as and when plants need it - perfect for hot, dry summers when rain is scarce

Australian Standard

Certified to meet the Australian Standard for Premium potting mixes


10L and 25L bags

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.

Plants that grow best in neutral to alkaline soils and potting mixes, including crabapples, mock orange, robinias and virburnums

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

  • Rose, Gardenia, Azalea and Camellia Mix provides the ideal growing environment for all plants needing growing medium with a pH of 6 or lower
  • It has been designed and is guaranteed to grow better plants from young saplings to mature trees

How to use

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 with fresh 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 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 direct 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 mix in the base and then spread the roots out over it.
  4. Once positioned, back fill 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
