How to Grow Golden Wattle
Acacia pycnantha
Golden Wattle is Australia's national floral emblem — a fast-growing evergreen shrub or small tree smothered in fragrant golden flower balls from late winter to spring. Plant in full sun and well-drained soil. Water deeply during the first year; once established it is highly drought tolerant. Use native low-phosphorus fertiliser only — high phosphorus is harmful. Prune lightly after flowering to maintain a bushy shape. Short-lived (15-20 years) but incredibly rewarding.
Yearly Lifecycle
Care Essentials
Apply a native low-phosphorus slow-release fertiliser in early spring and autumn. Avoid high-phosphorus products which are harmful to Australian natives.
Watch For
- Uromycladium rust galls
- Psyllids
- Scale insects
- Phytophthora root rot
Companions
Grevillea, Callistemon, Native grasses, Eremophila
Care Requirements
Light
Full sun
Requires full sun for at least 8 hours daily. Cannot tolerate shade. A sunny open position produces the densest flowering display.
Watering
Deep watering while establishing; drought tolerant once mature
Water deeply twice a week during the first 12 months. Once established, water only during extended dry spells. Overwatering and waterlogged soil cause root rot.
Fertilizing
Native low-phosphorus fertiliser only
Apply a native-formulated low-phosphorus slow-release fertiliser in early spring and autumn. Never use standard garden fertilisers — high phosphorus damages or kills Australian natives.
Pruning
Light prune after flowering; tip-prune in late summer
Prune lightly immediately after flowering to keep a tidy shape and encourage bushy growth. Tip-prune again in late summer. Avoid cutting into old hard wood.
Spacing
3-4 m apart as feature plants
Allow 3-4 m between plants as a specimen or feature tree. For informal screening, space 1-1.5 m apart. Very fast growing — give adequate room from the start.
