Orange Growing Guide
Citrus sinensis
![Orange]()
Crop Rotation Group
Miscellaneous ●
Soil
Warm, moist soil, well-enriched with organic matter. Oranges grafted onto a dwarfing rootstock may be grown in containers.
Position
Full sun.
Frost tolerant
No. Grow at temperatures above 7°C (45°F).
Feeding
In spring and summer, feed with a balanced organic fertiliser. Yellowing leaves indicate a need for more nitrogen.
Companions
Oranges and other citrus are heavy feeders that resent close company, so companion plants have to be planted a little way away.
Spacing
Single Plants: 5.00m (16' 4") each way (minimum)
Rows: 5.00m (16' 4") with 5.00m (16' 4") row gap (minimum)
Sow and Plant
Set out new plants in spring. Good drainage is essential.
Our Garden Planner can produce a personalised calendar of when to sow, plant and harvest for your area.
Notes
Prune in spring or summer to shape plants, and watch for thorns. Very sweet oranges need a long season of warm weather, but kumquats, calamondin oranges and satsumas fruit well in marginal areas or when grown in containers.
Harvesting
Pick when richly coloured and fully ripe. Picking can continue for several weeks as fruits do not ripen all at once.
Troubleshooting
Soft soap sprays can help against scale insects. In Australia fruit fly are a pest of oranges, make sure to take appropriate control measures in areas where they are present. It is important to dispose of any infected fruit and fruit has fallen to the ground by placing them in a sealed plastic bag in the sun for at least 7 days to kill the eggs and larvae. Do not compost fruit as this will lead to the fruit fly completing their life cycle and lead to the problem recurring.
