01Planting depth
Limes are the most frost-tender of the common citrus — give them the warmest, most sheltered spot available, ideally against a north-facing wall in cooler zones.
02Planting
Method
Plant with the graft union above soil level; stake loosely.
Soil
Well-drained, slightly acidic.
Timing
Plant in spring, in the warmest, most sheltered position you have.
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
- Protect from frost while young — even light frost can damage limes.
- Water deeply and regularly, especially through fruit set.
- Feed with a citrus fertiliser three times a year.
- Mulch around the drip line, clear of the trunk.
04Problems
- Frost damage — the main risk; shelter or cover in cold snaps.
- Citrus leaf miner — silvery trails; prune affected tips.
- Gall wasp — swollen stems; prune out before spring.
- Sooty mould — follows sap-sucking pests; treat the pest.
05Harvest & storage
Signs
