About Your New Acacia implexa Lightwood

Acacia implexa, the Lightwood or Hickory Wattle, is a fast-growing Australian native valued for its hardiness, ecological function, and graceful form. The slender upright habit and light green curved phyllodes give it a soft, airy presence, while pale yellow fragrant flowers appear in late summer to support native insects and birds.

Lightwood grows to 8-15 metres tall and 4-6 metres wide. The deep root system, nitrogen-fixing ability, and tolerance of poor soils make it an excellent choice for revegetation corridors, rural shelterbelts, erosion control, and habitat planting where long-term resilience matters more than ornamental polish.

Lightwood thrives in full sun and tolerates drought, seasonal dryness, and light frost once established. It performs reliably across most of eastern and southern Australia, and is widely specified for council planting, soil-improvement zones, and low-input rural landscapes.

Long Term Care For Your Acacia implexa Lightwood

Watering: Water deeply twice weekly through the first 12 months. Once established, this is drought tolerant and only needs a deep soak during extended dry periods.

Mulching: Apply a 5 to 7 centimetre layer of organic mulch over the root zone, keeping it 5 centimetres clear of the trunk.

Pruning: Tip prune in late winter and again in summer to build dense growth. For a formal hedge, light shaping two to three times a year keeps lines crisp.

Fertilising: Apply a slow-release native blend in early spring and again in autumn. Avoid high-phosphorus formulations as a precaution.

Pest and disease: Hardy against most pests and diseases. Occasional inspection in warm humid conditions is all that's needed.
