Sale price$250.00

The Acacia longifolia – Sydney Golden Wattle is a fast-growing, evergreen native shrub or small tree (4–10m H × 2–5m W) with long green phyllodes and dense golden flower spikes from late winter to early spring. It looks excellent along rural boundaries, in mass native plantings, or naturalised into sloped landscapes where fast cover and vibrant seasonal colour are needed.

Acacia longifolia – Sydney Golden Wattle thrives in full sun, tolerates drought, poor soils, and coastal exposure, and is commonly used for erosion control, windbreaks, and habitat planting. Its nitrogen-fixing roots improve soil structure and support surrounding vegetation.

Low maintenance and quick to establish, this variety is ideal for revegetation zones, large-scale planting, or low-input gardens. Space 2–3m apart for full spread.

How to Plant Acacia Longifolia (Sydney Golden Wattle)

Planting Tips: Ensuring a Strong Start for Acacia longifolia (Sydney Golden Wattle)

Proper planting is essential to give your Acacia longifolia the best start for healthy growth and long-term success. Follow these key steps to ensure a strong establishment:

1. Choosing the Right Location

  • Select a site with full sun to partial shade for optimal growth and flowering.
  • Ensure good air circulation to promote healthy foliage and prevent disease.
  • Consider spacing requirements to allow for future growth – plant 2-4 meters apart for screening purposes.

2. Preparing the Soil

  • Acacia longifolia thrives in well-drained soils, including sandy, loamy, or coastal soils.
  • If planting in clay or compacted soils, improve drainage by adding organic matter, sand, or gypsum.
  • Conduct a soil test to ensure a slightly acidic to neutral pH (6.0-7.5).

3. Digging the Planting Hole

  • Dig a hole twice as wide and the same depth as the plant’s root ball.
  • Loosen the surrounding soil to encourage root expansion.
  • Avoid planting too deep—ensure the top of the root ball is level with the ground surface.

4. Planting the Tree

  • Carefully remove the plant from its container and gently loosen the roots if pot-bound.
  • Position the tree in the hole and backfill with a mix of native soil and organic compost.
  • Lightly tamp the soil to remove air pockets while ensuring good root contact.

5. Watering After Planting

  • Water deeply immediately after planting to help settle the soil.
  • Maintain consistent moisture during the establishment period (first 6-12 months).
  • Once established, reduce watering frequency as the tree becomes drought-tolerant.

6. Mulching for Moisture Retention

  • Apply a 5-7 cm layer of mulch around the base to retain moisture and regulate soil temperature.
  • Keep mulch a few centimeters away from the trunk to prevent rot and pest issues.

7. Fertilizing for Healthy Growth

  • Use a low-phosphorus native fertilizer during the growing season to promote healthy foliage and root development.
  • Avoid over-fertilizing, as Acacia species thrive in low-nutrient conditions.

8. Staking (If Needed)

  • Stake young plants only if necessary to support against strong winds.
  • Use soft ties and avoid tying too tightly to allow natural movement and strength development.

9. Pruning for Shape and Health

  • Light pruning after flowering can help maintain shape and encourage denser growth.
  • Remove dead or damaged branches to promote airflow and overall plant health.

10. Protection from Pests and Diseases

  • While generally hardy, watch for pests such as scale insects and aphids.
  • Ensure proper spacing and airflow to prevent fungal issues such as root rot in poorly drained areas.

Following these planting tips will help your Acacia longifolia establish quickly, providing lush growth, vibrant blooms, and long-lasting beauty in your landscape.
