Care at a glance

Light

Burrawang Palm is what florists mean by "bright spot, no direct sun" — close enough to a south or east window to feel the brightness, with a sheer curtain or a few feet of distance keeping the sun off the leaves. Thrives in bright, filtered light or partial shade. Direct afternoon sun in hot climates can scorch leaflets; morning sun is tolerated. In containers indoors, position near a bright window with indirect light. A phone lux-meter at the leaf surface should read 1,500-3,000 lux at noon.

Watering

Water burrawang palm every 2–3 weeks. The actual day count varies with pot size, light, and season — the finger test (or lifting the pot to feel its weight) is more reliable than a fixed calendar. Empty any drainage saucer afterwards so the pot isn't sitting in water. Drought-tolerant once established. Water deeply then allow the soil to dry out almost completely between waterings. Overwatering is the most common cause of root rot. Reduce watering further in winter.

Soil and pot

Burrawang Palm grows best in sandy, free-draining loam. Requires excellent drainage. Use a mix of coarse sand, perlite, and loam (or a cactus/palm blend). Avoid heavy clay or moisture-retentive potting mixes. Naturally grows in sandstone-derived soils in the wild. A pot with a working drainage hole is non-negotiable for this species — even free-draining mix will turn soggy in a closed planter. If you love the look of a decorative pot without a hole, use it as a cachepot around an inner nursery pot you can lift out to water.

Humidity and temperature

Burrawang Palm sits happiest at around 30–60% humidity and 10–35°C (50–95°F). Tolerates average to low indoor humidity. Not sensitive to dry air as long as roots are not waterlogged. No misting required. If you keep the room above 10–35°C year-round and avoid placing the plant near a cold draught, a hot radiator, or an air-conditioning vent, you have already handled the two biggest indoor stressors.

Fertilising

Feed burrawang palm sparingly. Apply a slow-release fertiliser formulated for cycads or palms in spring and again in midsummer. Cycads have modest nutrient needs; excess nitrogen produces lush but weak growth. Do not fertilise in autumn or winter. Skip fertiliser entirely on a stressed, recently-repotted, or actively wilting plant — fertiliser salts make damage worse, not better. Wait for a round of healthy new growth before resuming a feeding rhythm.

Common problems

Below are the issues we see most often on burrawang palm in the Growli community. Each is annotated with the most common cause so you know where to start.

  • Root rotCaused by overwatering or poorly drained soil. Symptoms include yellowing fronds and a soft, mushy caudex base. Remove affected roots, dust with fungicide, and repot into dry, free-draining mix. Allow the plant to dry before resuming watering.
  • Scale insectsBrown or white scale can colonise the undersides of leaflets and along the rachis. Treat with horticultural oil or a systemic insecticide labelled for cycads. Inspect new flushes carefully as they are most vulnerable.
  • Manganese deficiencyNew fronds emerge yellow or with interveinal chlorosis — common in cycads grown in alkaline soils or containers. Apply a chelated manganese supplement or a cycad-specific micronutrient spray.

Propagation

Propagate by removing offsets (pups) that develop at the base of the caudex. Detach when they have at least 3–4 leaves, dust the cut surface with fungicide, allow to callous for 24 hours, then pot into dry sandy mix. Seeds germinate in 3–6 months if sown fresh and kept warm (25–30°C), but seedlings grow extremely slowly. Propagation is the cheapest, most satisfying way to expand a collection — and it doubles as insurance against losing a mature plant to an accident. Take a backup cutting once the parent is established and healthy.

Toxicity to pets

Burrawang Palm is toxic to pets. All parts of Macrozamia spiralis are severely toxic to dogs, cats, and humans. The plant contains cycasin (methylazoxymethanol glucoside), which causes vomiting, liver failure, and potentially death. Seeds (nuts) are the most concentrated source. The ASPCA classifies cycads (Macrozamia spp.) as toxic to dogs and cats. Seek emergency veterinary care immediately if ingestion is suspected. If you keep cats, dogs, or curious children in the house, weigh placement carefully — a high shelf or a hanging planter is enough for casual safety. For severe ingestion incidents, call your local vet and the ASPCA Animal Poison Control Center (in the US, 888-426-4435).

Pet-safety status is sourced from the ASPCA Toxic and Non-Toxic Plant List, which catalogues the most-asked-about plants for cats, dogs, and horses.

Burrawang Palm care — frequently asked questions

What is the common name for Macrozamia spiralis?

Macrozamia spiralis is most commonly called Burrawang Palm, but it is also known as Burrawang Palm, Burrawang, Spiralling Macrozamia. The names refer to the same species, so care instructions for Burrawang Palm apply identically to anything sold as Burrawang.

How much light does burrawang palm need?

Burrawang Palm grows best in bright indirect light (just back from a sunny window). Thrives in bright, filtered light or partial shade. Direct afternoon sun in hot climates can scorch leaflets; morning sun is tolerated. In containers indoors, position near a bright window with indirect light.

How often should I water burrawang palm?

Water burrawang palm every 2–3 weeks. Drought-tolerant once established. Water deeply then allow the soil to dry out almost completely between waterings. Overwatering is the most common cause of root rot. Reduce watering further in winter. The finger-test (or lifting the pot to feel its weight) beats a fixed weekly calendar because pot size, light, and season all change how fast the soil dries.

Is burrawang palm toxic to cats and dogs?

Burrawang Palm is toxic to pets. All parts of Macrozamia spiralis are severely toxic to dogs, cats, and humans. The plant contains cycasin (methylazoxymethanol glucoside), which causes vomiting, liver failure, and potentially death. Seeds (nuts) are the most concentrated source. The ASPCA classifies cycads (Macrozamia spp.) as toxic to dogs and cats. Seek emergency veterinary care immediately if ingestion is suspected.

What USDA hardiness zone does burrawang palm grow in?

Burrawang Palm is rated for USDA zone 9-11 and RHS hardiness H2. Outside that range, grow it as a container plant that overwinters indoors before the first hard frost.
