Sun
Full sun, sheltered
Water
Regular, deep
Soil pH
5.5–6.5
Spacing
4–5m
Depth
graft union above soil
01Planting 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.
02Planting
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.
Planting timing varies significantly by Australian climate zone. Set your zone above (or use the Find My Climate Zone tool) for guidance tailored to your own area.
03Growing care
- 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.
04Problems
- 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.
05Harvest & storage
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.
Preserving
See Canning & Bottling (marmalade and preserved citrus) for ways to keep a harvest surplus.
