Growing Lime in Australia: The Complete Guide
Lime is a moderate citrus tree to grow, needing full , sheltered sun with regular, deep watering.
Video transcript
Intro: Holly's Homestead.
Title card: Lime — difficulty: Moderate.
Quick reference: Sun: Full sun, sheltered; Water: Regular, deep; Soil pH: 5.5–6.5; Spacing: 3–4m; Depth: graft union above soil.
Planting: Method: Plant with the graft union above soil level; stake loosely.
Growing care: Protect from frost while young — even light frost can damage limes.
Problems: Frost damage — the main risk; shelter or cover in cold snaps.
Harvest & storage: Signs: Full size, still green (most limes are picked green) and glossy.

Lime is one of the moderate additions to a home garden, and this article walks through everything behind our one-page printable guide in a good deal more depth than a single card allows.
Every crop earns its place in a garden differently, and lime is no exception. At a glance, it's rated moderate, with a sun of full sun, sheltered; water of regular, deep; soil ph of 5.5–6.5 — details that matter more once you're actually planning around them than they do on a first read. The rest of this article works through exactly what each of those means day to day, in more depth than a single printable card has room for, and with the reasoning behind each recommendation rather than just the recommendation itself.
Climate and Timing Considerations
Australia's climate zones change growing timing more than most general advice accounts for. Cool temperate zones (Tasmania, the Victorian highlands, southern NSW) have recurring frost risk well into what other zones call spring, which compresses the safe planting window for frost-tender plantings. Warm temperate zones (Sydney, Adelaide, Melbourne, Perth) sit closest to what general advice assumes by default. Subtropical zones (Brisbane, northern NSW) rarely see frost at all, and the growing calendar shifts earlier and later as a result. Our site-wide zone setting adjusts the advisory note shown on the Planting Calendar for exactly this reason — worth setting once if you haven't already. The same zone setting also feeds the Harvest Calendar, so both ends of the growing cycle reflect wherever you actually garden, rather than a generic Australia-wide average.
- Cool Temperate (TAS, VIC highlands, southern NSW, ACT): shorter frost-free window — lean toward the later end of any spring planting window shown on the guide above.
- Warm Temperate (Sydney, Adelaide, Melbourne, Perth, coastal NSW/WA): closest match to the general timing shown above; frost is occasional but rarely severe.
- Subtropical (Brisbane, northern NSW, coastal QLD): minimal frost risk — often plantable a few weeks earlier and later than the general window shown above.

Planting 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.
Getting Lime Into the Ground
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.
Taken together, these are the details that separate a smooth result from a frustrating one.
Day-to-Day Care
Worth paying attention to:
- 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.
Getting these details right matters more than it might seem — protect from frost while young — even light frost can damage limes. Mulch around the drip line, clear of the trunk. Treat this list as a routine to build rather than a one-off checklist, and it becomes second nature within a season or two.
Common Problems
Keep these points in mind:
- 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.
Each of these compounds over a season — small misses early tend to show up later — frost damage — the main risk; shelter or cover in cold snaps. Sooty mould — follows sap-sucking pests; treat the pest. Treat this list as a routine to build rather than a one-off checklist, and it becomes second nature within a season or two.
When and How to Harvest
Signs. Full size, still green (most limes are picked green) and glossy.
Method. Cut or twist from the stem.
Curing. None needed.
Storage. Room temperature about a week, or refrigerated 2–3 weeks.
It's worth reading these as a set rather than in isolation; they reinforce each other.
Preserving. See Canning & Bottling for marmalade and preserved citrus.
Companions & rotation
Our printable card above lists specific plants that pair well nearby and others best avoided, along with a rotation note: Comfrey, Marigold, Garlic, Close tree planting. Getting this right matters more over multiple seasons than it does in any single one — the benefits and the risks of poor rotation both compound over time rather than showing up immediately.

Companion planting and bed rotation both make a measurable difference over a season, and our Companion Planting Checker takes the guesswork out of both. As with every guide on this site, this is general information based on our own research and experience, not professional advice — your specific soil, climate, and circumstances will always vary from ours to some degree.
Beyond the printable card, our Planting Calendar and Harvest Calendar tools will show a zone-adjusted note for lime specifically, and the Companion Planting Checker covers the specific pairings mentioned above in more detail.
