Use Orchid Mix straight from the bag - don't mix it with other materials. Close the bag tightly after use
Choose a clean container with large drainage holes and partly fill it with fresh mix out of the bag
Carefully knock the plant to be potted up from its existing pot and loosen the root ball. If the plant is congested, separate into either individual pseudo bulbs or groups of 3-4 bulbs. Trim off any dead or damaged roots
Place the orchid in the centre of the pot with the crown just below the lip of the pot and clear of the top of the mix when repotting is complete - don't 'bury' pseudobulbs)
Add the mix in and around the roots, working it in with your fingers if necessary
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
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
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
Most orchids have fairly thick, fleshy roots, so it is important to use only a specially formulated Orchid Mix for them - normal potting mixes are too dense and retain too much moisture which could cause roots to rot.

Epiphytic orchids like Phalaenopsis (Moth Orchids) and Dendrobium have aerial roots, so never set them too deeply in pots - use stakes to hold them in place securely


Orchids are best repotted in mid Spring, or immediately after they have finished flowering
Avoid Winter or Summer as the extremes of temperature may stress plants

Read our Orchid growing guide for more details.


Don't use for phosphorus sensitive Australian native ground orchids like greenhoods, donkey and sun orchids - use Scotts Osmocote® Professional Native Potting & Planting Mix instead
Don't use in hydroponic growing systems or ponds
Don't use on lawns - use only specifically named lawn topdress soils on grassed areas
