Choose a pot up to twice the size of the selected plant. Position in a well-lit area and fill with a low nutrient quality growing media, such as Yates Seed Raising Mix with some sphagnum moss mixed in.
Rinse well several times to flush away any soluble minerals in the mix.
Remove the plant from its container, minimising disturbance to the roots.
Position in hole and backfill with soil, gently firming down. Water in very well, but allow to drain freely.
If insects are few and far between, you can try some Yates Thrive Orchid Liquid Plant Food, at half the directed rate and in a light spray directly onto foliage (avoid applying to growing media).
Sitting pots in a shallow tray of water is an easy way to maintain moisture in the growing media, but this should be refreshed daily. Where possible, regular watering (several times a day as required) of a freely drained pot would instead be ideal.
Drainage is more critical when growing indoors, but never let the potting media dry out.
You may need to slowly acclimatise your plants to full sun if they were previously grown in low/artificial light conditions.
Avoid using water with high levels of dissolved minerals (‘hard water’). Clean rainwater is often ideal, where available or alternatively use deionised water.
