Growing Lentils in Australia: The Complete Guide

Lentils is an easy legume to grow, needing full sun with low–moderate watering.

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

It's worth being clear about why lentils is worth the bed space before getting into how to grow it. At a glance, it's rated easy, with a sun of full sun; water of low–moderate; soil ph of 6.0–7.0 — 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.

Nitrogen fixers

A low, bushy legume that's easy to grow at a small scale — worthwhile on a homestead less for yield efficiency and more for the soil-building benefit and the novelty of home-grown lentils.

Planting Lentils

Method. Direct sow, fairly dense.

Soil. Well-drained, even poor soil is tolerated.

Timing. Sow in the cooler months.

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

Keeping It Growing Well

A few things matter most here:

• Water lightly and consistently while establishing.
• Weed while young — low growth is easily outcompeted.
• Avoid excess nitrogen fertiliser, which grows leaf over pods.
• Leave roots in place after harvest for the nitrogen benefit.

These aren't equally important, but all of them are worth building into your routine — water lightly and consistently while establishing. Leave roots in place after harvest for the nitrogen benefit. 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

The key things to get right:

• Fungal rot — humid, wet conditions; ensure good airflow and drainage.
• Aphids — occasional cluster on tips; hose off.
• Poor pod set — heat stress; grow in the cooler months.
• Bird damage to seedlings — net if pressure is high.

None of these are complicated on their own, but skipping one is a common source of trouble — fungal rot — humid, wet conditions; ensure good airflow and drainage. Bird damage to seedlings — net if pressure is high. Treat this list as a routine to build rather than a one-off checklist, and it becomes second nature within a season or two.

Picking and Keeping Your Harvest

Signs. Pods dry and rattle, plants yellow.

Method. Pull whole plants and thresh once fully dry.

Curing. Dry thoroughly before storing.

Storage. Airtight, cool, dark — keeps well over a year dried.

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

Preserving. See Canning & Bottling for canning cooked beans, if you want them ready-to-eat on the shelf beyond the dry storage above.

Companions & rotation

Our printable card above lists specific plants that pair well nearby and others best avoided, along with a rotation note: Corn, Carrot, Onion, Garlic. 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 lentils. 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 lentils specifically, and the Companion Planting Checker covers the specific pairings mentioned above in more detail.
