Growing Orange in Australia: The Complete Guide
Orange is an easy to moderate citrus tree to grow, needing full , sheltered sun with regular, deep watering.
If you're thinking about adding orange to the homestead, here's the real detail behind our printable guide — what it actually takes to grow it well in an Australian garden.
Planting depth
As with all grafted citrus, keep the graft union 5–10cm above soil level. Oranges are a little more frost-tender than lemons — choose a warm, sheltered position.
Getting Orange Into the Ground
Method — plant with the graft union above soil level; stake loosely in the first year. Soil — well-drained, slightly acidic; raised mounds in heavy clay. Timing — plant in spring, in a warm, sheltered, sunny spot.
Day-to-Day Care
The key things to get right:
- Water deeply and regularly, especially through flowering and fruit set.
- Feed with a citrus fertiliser in early spring, late summer, and autumn.
- Mulch around the drip line, clear of the trunk.
- Prune lightly after harvest to open the canopy.
What Can Go Wrong
A few things matter most here:
- Citrus leaf miner — silvery trails on new growth; prune tips.
- Gall wasp — swollen stems; prune out galls before spring.
- Sooty mould — follows sap-sucking pests; treat the pest.
- Fruit drop — irregular watering or stress; keep care consistent.
When and How to Harvest
Signs — full colour, sweet taste on testing — colour alone isn't always a reliable guide. Method — cut or twist from the stem. Curing — none needed — fruit holds well on the tree. Storage — room temperature 1–2 weeks, or refrigerated up to a month.
