Growing Peanuts in Australia: The Complete Guide

Peanuts are a moderate nut to grow, needing full sun with regular watering, especially during flowering and pod set.

Video transcript

Intro: Holly's Homestead.

Title card: Peanuts — difficulty: Moderate.

Quick reference: Sun: Full sun; Water: Regular, especially during flowering and pod set; Soil pH: 5.8–7.0; Spacing: 10–15cm apart, rows 50cm apart; Depth: 4–5cm.

Planting: Sow raw peanuts 4–5cm deep once soil is warm and loose.

Growing care: Water through flowering, hill soil round the base and add calcium.

Problems: Leaf spot, nematodes and seed thieves — and dry nuts fast to avoid mould.

Harvest & storage: Yellowing leaves — lift whole plants, hang to dry 2–3 weeks, then shell.

Peanuts are a moderate nut to grow, 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 peanuts are no exception. At a glance, they're rated moderate, with a sun of full sun; water of regular, especially during flowering and pod set; soil ph of 5.8–7.0 — 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, 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 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): marginal — peanuts need around five frost-free months, so start under cover and choose an early variety.
  • Warm Temperate (Sydney, Adelaide, Melbourne, Perth, coastal NSW/WA): sow October to November once the soil has warmed; a warm summer gives a reliable small crop.
  • Subtropical (Brisbane, northern NSW, coastal QLD): peanut country — most of Australia’s commercial crop is grown in southern Queensland; sow September to November.

Pegs and pods

After flowering, the flower stalks (pegs) bend down and push into the soil, where the pods form underground. That is why light, loose soil matters more than almost anything else.

Getting Peanuts Into the Ground

Method. Sow raw, unroasted peanuts, shelled just before sowing so the skins stay intact, 4–5cm deep.

Soil. Light, sandy, loose and well-drained. Heavy clay stops the pegs from penetrating the soil.

Timing. Sow in spring once soil is above 18°C (September–November in the subtropics, October–November further south). Needs around 5 frost-free months.

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

Day-to-Day Care

A few things matter most here:

  • Water regularly through flowering and pod set, then reduce as the crop matures.
  • Hill loose soil around the base when flowering begins so the pegs reach soil easily.
  • Add gypsum or lime at flowering if soil is low in calcium — a shortage causes empty pods.
  • Mulch lightly and weed by hand; deep hoeing damages the pegs.

These aren't equally important, but all of them are worth building into your routine — hilling soil and keeping calcium up around flowering matter most, since pods only form where the pegs can reach loose soil. Treat this list as a routine to build rather than a one-off checklist, and it becomes second nature within a season or two.

What Can Go Wrong

The key things to get right:

  • Leaf spot — brown spots with yellow halos on leaves; space for airflow, rotate crops and avoid overhead watering.
  • Root-knot nematodes — knobbly galls on roots, common in sandy soil; rotate and add plenty of organic matter.
  • Seed thieves — cockatoos, rats and possums dig up sown seed; net the bed until seedlings are up.
  • Mould and aflatoxin — poorly dried or damaged nuts can grow a mould that makes aflatoxin; dry quickly and discard any mouldy, shrivelled or discoloured nuts.

None of these are complicated on their own, but skipping one is a common source of trouble — mould in particular is worth avoiding, since poorly dried peanuts can be unsafe to eat. 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 yellow and the lower ones drop; dig one plant — the inside of the shell is veined and the kernel fills the pod, about 4–6 months after sowing.

Method. Loosen the soil with a fork and lift whole plants gently, shaking off soil but leaving the pods attached.

Curing. Hang the plants, or stack them pods-up, in a warm airy shed for 2–3 weeks until the pods rattle, then pick them off.

Storage. In-shell, cool, dry and ventilated, 6–12 months. Shelled raw peanuts keep a few months in the fridge, longer frozen.

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

Preserving. See Dehydrating for drying nuts fully before storage.

Companions & rotation

Peanuts fix their own nitrogen, so they pair well with heavy feeders like corn and with sprawling pumpkin, but do not plant them near onions or garlic. Rotating on a roughly three-year cycle avoids soil disease build-up, and this matters more over multiple seasons than in any single one.

That's the full picture behind peanuts. 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. 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 peanuts specifically, and the Companion Planting Checker covers companion pairings in more detail.

Frequently Asked Questions

What sun does Peanuts need?

The quick answer from our guide: Full sun. See the full guide above for how this plays out day to day.

What water does Peanuts need?

Per our printable card, this comes down to: Regular, especially during flowering and pod set. See the full guide above for how this plays out day to day.

Do peanuts grow on trees?

No. Peanuts are a legume, like beans — the plant grows close to the ground and its pods ripen underground, which is why they are sometimes called groundnuts.

Can I plant peanuts from the supermarket?

Roasted or blanched peanuts will not sprout. Raw, in-shell peanuts sometimes will, but seed-grade peanuts from a garden supplier germinate more reliably.

Is it safe to eat home-grown peanuts?

Yes, provided they are dried properly. Poorly dried or damaged peanuts can grow a mould that produces aflatoxin, so dry them quickly and throw out any that are mouldy, shrivelled or discoloured.

Is peanuts an easy crop to grow in Australia?

We rate it moderate — see the full guide above for exactly what that involves in practice.
