Growing Guide

Plant Kangaroo Paws in spring (September to November) when soil temperatures are warming, giving plants time to establish before the heat of summer. Autumn planting (March to May) also works well in warmer climate zones.

Soil Preparation: Kangaroo Paws demand excellent drainage. Before planting, dig through coarse sand or fine gravel into your garden bed to improve drainage. Avoid heavy clay soils, which cause root rot. Raise beds if necessary and ensure a slightly acidic to neutral pH of 6.0–7.0.

Watering: Water regularly for the first six to eight weeks after planting to help establishment. Once settled, reduce watering significantly — Kangaroo Paws are drought-tolerant and prefer to dry out between watering sessions. Overwatering is the most common cause of plant decline. In summer, a deep weekly water is usually sufficient.

Feeding: Apply a low-phosphorus native plant fertiliser in early spring and again in early autumn. Avoid high-phosphorus fertilisers, which are toxic to most Australian native plants.

Mulching: Apply a 5–7 cm layer of coarse mulch around plants, keeping it clear of the crown to prevent rot and maintain soil moisture during dry periods.

Cut Flowers: For the best cut flowers, harvest stems early in the morning when about half the flowers on a spike have opened. Cut stems at the base and place immediately in water to prolong vase life significantly.

🤝 Good Companions

Kangaroo Paws pair beautifully with Lomandra Grevillea and Westringia as these Australian natives share similar low-phosphorus soil preferences drought tolerance and full-sun requirements creating a cohesive low-maintenance native garden that supports local wildlife. Adding Scabiosa or native grasses like Poa labillardieri softens the overall planting design while complementing the bold flower spikes with texture and movement.

❌ Avoid Planting With

Avoid planting Kangaroo Paws near phosphorus-hungry plants such as roses or exotic flowering annuals that require rich fertilised soils as the high-nutrient feeding programs required by these plants can cause fatal phosphorus toxicity in Kangaroo Paws. Heavy water users like ferns or azaleas should also be kept well away as their moisture requirements are completely incompatible with the dry conditions Kangaroo Paws need to thrive.

🐛 Pests & Diseases

Ink disease, caused by the fungal pathogen Alternaria alternata, is the most serious problem for Kangaroo Paws in Australian gardens, causing distinctive black streaking on leaves and flower stems; improve air circulation, remove and destroy affected foliage, and apply a registered copper-based fungicide as an organic control. Snails and slugs may graze on young foliage, particularly after rain — control organically with iron-based baits, crushed eggshells around the base, or by hand-picking at night. Spider mites can occasionally attack stressed plants during hot, dry spells and are best managed by ensuring adequate water during extreme heat and applying a neem oil spray.

🌱 Fertilising

Feed Kangaroo Paws with a quality low-phosphorus native plant fertiliser, such as those specifically formulated for Australian natives, in early spring (September) and again in early autumn (March) to support healthy flowering and foliage growth. Avoid standard garden fertilisers containing high phosphorus levels, as these are harmful to most Proteaceae-family plants and their neighbours; slow-release native formulas such as Osmocote Native or similar are ideal choices for Australian conditions.

✂️ Pruning & Training

After flowering has finished, cut spent flower stalks down to the base of the plant using clean, sharp secateurs to encourage a fresh flush of growth and reduce the risk of ink disease developing on old material. In late autumn or winter, give plants a hard 'tidy prune' by cutting old or blackened foliage back to about 10–15 cm above ground level, which reinvigorates the plant and promotes vigorous new growth and flowering in the coming season.

🔬 Propagation

Kangaroo Paws are most reliably propagated by division in autumn or early spring — carefully dig up established clumps, separate the rhizomes into sections each containing healthy roots and foliage fans, and replant divisions immediately at the same soil depth in a well-draining position. Propagation from seed is also possible; sow fresh seed in spring into a free-draining native propagating mix, keep moist but not wet, and expect germination within three to six weeks, though named hybrid cultivars will not come true to type from seed.
