Expert tips
The key tip
Water sparingly after establishment (3-4 months): this acacia fears constant moisture. Sandy or gravelly soil is ideal, otherwise amend at planting.
The common mistake
People grow it like a temperate plant with regular watering: it'll rot its roots in humid climates.
The pro's trick
Sow slightly scarified seeds pre-soaked for 24 hours: germination will be fast and you'll save space.
Care
Exposure
The Acacia acinacea requires a sunny position for optimal flowering. Plant it in full sun, in a well-ventilated and open spot. A south or south-west facing exposure is ideal in temperate regions.
Watering
Once established, this acacia tolerates drought well. Water regularly during the first year after planting to encourage root development. Afterwards, reduce watering and only intervene during prolonged dry spells.
Soil
Prefer well-drained, light soil that is low in lime. Poor soil suits this hardy species perfectly. Avoid heavy, wet soils that promote root rot.
Pruning and maintenance
Prune lightly after flowering to maintain a compact, well-branched shape. Remove dead or misshapen branches. Severe pruning can weaken the shrub; favour gentle, gradual intervention.
Fertiliser
This acacia is not demanding and requires only moderate fertiliser. A light application in spring is sufficient. Avoid excessive nitrogen, which would favour foliage at the expense of flowering.
Pests and diseases
Generally robust, Acacia acinacea is especially wary of stagnant moisture and excess water. Watch for scale insects in hot, dry climates. Good ventilation and adequate drainage prevent most fungal problems.
Did you know?
The Acacia acinacea is native to Western Australia, where its name 'acinacea' literally means 'sword-shaped', referring to the distinctive shape of its phyllodes (modified leaves). This species has long been cultivated in the Mediterranean and North Africa for its remarkable adaptation to dry climates and spectacular spring flowering.
Where to buy it
Best planted in autumn so the roots settle in before summer, or in early spring once the frost has passed. Pick a plant with healthy foliage and roots that are not exposed. Best time: March, October, November.
