Growing Lemon Myrtle in Australia: The Complete Guide

Lemon Myrtle is an easy native bush food to grow, needing full –part shade, sheltered sun with regular watering.

We get asked about lemon myrtle often enough that it's worth setting out the full picture here, beyond what fits on our printable card.

Every crop earns its place in a garden differently, and lemon myrtle is no exception. At a glance, it's rated easy, with a sun of full sun–part shade, sheltered; water of regular; soil ph of 5.5–7.0 — 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.

An aromatic native hedge

Lemon myrtle clips well into a dense, fragrant hedge and provides an intensely lemon-scented leaf year-round — a useful and attractive native for a homestead herb garden.

Getting Lemon Myrtle Into the Ground

Method. Plant from a nursery pot.

Soil. Well-drained, moderately fertile.

Timing. Plant in spring in a sheltered spot.

None of these are difficult individually — the value is in getting all of them right at once.

Day-to-Day Care

The key things to get right:

• Protect from frost while young — more cold-sensitive than many natives.
• Water regularly while establishing.
• Clip as a hedge, or leave free-form.
• Harvest leaves regularly, which encourages fresh growth.

None of these are complicated on their own, but skipping one is a common source of trouble — protect from frost while young — more cold-sensitive than many natives. Harvest leaves regularly, which encourages fresh growth. Treat this list as a routine to build rather than a one-off checklist, and it becomes second nature within a season or two.

Problems to Watch For

A few things matter most here:

• Frost damage — the main risk while young; shelter in cooler zones.
• Myrtle rust — orange spore masses on new growth; remove affected material, improve airflow.
• Scale insects — occasional; treat with horticultural oil.
• Slow establishment — be patient in the first couple of years.

These aren't equally important, but all of them are worth building into your routine — frost damage — the main risk while young; shelter in cooler zones. Slow establishment — be patient in the first couple of years. Treat this list as a routine to build rather than a one-off checklist, and it becomes second nature within a season or two.

Harvest and Storage

Signs. Leaves are usable year-round once established.

Method. Pick leaves as needed.

Curing. Dries very well, retaining strong flavour.

Storage. Fresh, fridge a week or so; dried, airtight for a year or more.

Preserving. See Dehydrating for long-term storage, or Freezing Produce for a harvest surplus.

These few details do most of the actual work, more than any single trick or shortcut would.

Companions & rotation

Our printable card above lists specific plants that pair well nearby and others best avoided, along with a rotation note: Other natives, Frost-prone, exposed positions. 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.

That's the full picture behind lemon myrtle. The printable A4 version of this guide — with the quick-reference gauges and diagram in one page — is available on the main guide page below. If you're planning a whole bed rather than a single plant, our Companion Planting Checker is worth using alongside this guide. 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 lemon myrtle specifically, and the Companion Planting Checker covers the specific pairings mentioned above in more detail.
