Learn About Your New Eucalyptus grandis - Flooded Gum

Eucalyptus grandis (Flooded Gum) is a tall, fast-growing Australian native tree widely valued for its clean white trunk, upright form, and adaptability to high-rainfall regions.

This iconic hardwood species reaches heights of 30–50 metres in ideal conditions and is best suited to large-scale landscapes, revegetation projects, and timber production sites where fast canopy development and bold vertical presence are needed.

Eucalyptus grandis (Flooded Gum) features a smooth, powdery white trunk that sheds seasonally to reveal soft grey or pink tones beneath, offering year-round interest. Its long, lance-shaped green leaves create a lightly filtered canopy, making it suitable for habitat support, wind protection, and shade in open rural settings.

Flowering in summer, this species produces clusters of small white flowers that attract bees and native pollinators, increasing biodiversity value. It thrives in deep, fertile, well-drained soils, especially in moist environments along creeks, gullies, and floodplains.

Due to its size and water requirements, Eucalyptus grandis (Flooded Gum) is not recommended for confined or dry landscapes. However, for rural properties, forestry, erosion control, or carbon planting projects, it remains one of the best-performing native species available.

Ensuring A Strong Start

Planting Tips: Ensuring a Strong Start

Site Selection:

Choose a location in full sun with deep, fertile, and well-drained soil. Avoid planting near buildings or power lines due to the tree’s mature height.

Digging the Hole:

Dig a hole twice as wide as the root ball and of equal depth. This encourages lateral root spread and helps establish stability.

Soil Preparation:

Loosen the surrounding soil. If the native soil is poor, amend it with compost to improve fertility and structure. Avoid over-fertilizing at planting.

Planting:

Place the tree in the hole so that the top of the root ball is level with the soil surface. Backfill gently and firm the soil to eliminate air pockets.

Watering In:

Water thoroughly immediately after planting to help settle the soil around the roots.

Mulching:

Apply a 5–7 cm thick mulch layer around the base (but not touching the trunk) to retain moisture, suppress weeds, and moderate soil temperature.

Root Ball Dimensions (Width × Depth) for Planting

Use this as a reference when digging your planting hole. We recommend digging at least 10% wider than the dimensions below to encourage strong root development.

  • 30cm Pot: 33cm (W) × 30cm (D)
  • 40cm/45L Pot: 44cm (W) × 41.5cm (D)
  • 50cm Pot: 49.5cm (W) × 35.2cm (D)

Post Planting Care

When planting a new tree or shrub, proper watering is essential to ensure healthy establishment and long-term growth. Follow these guidelines to give your plant the best start:

  1. Immediately After Planting:
    Water generously right after planting to settle the soil around the roots and eliminate air pockets. This helps the roots make good contact with the soil.
  2. First Three Months (Establishment Phase):
    The initial three months are critical for root development. Water deeply twice daily (morning and evening) to encourage strong, deep root growth.
  3. Irrigation Systems:
    If using an irrigation system, adjust it to provide adequate water during the establishment phase. Ensure the water reaches the root zone without overwatering.
  4. Weather Considerations:
    Adjust watering based on weather conditions. Increase frequency during hot, dry periods and reduce it during cooler, wetter seasons.
  5. Ongoing Care:
    After the establishment phase (3 months), gradually reduce watering frequency but ensure the plant receives consistent moisture, especially during dry spells.

Long Term & Ongoing Care

Caring For Your Tree

Watering:

  • Establishment Phase (First 12 months): Water deeply once or twice per week depending on rainfall and soil drainage.

  • Mature Trees: Typically require minimal watering, but deep watering during prolonged dry periods will support long-term health and growth.

Fertilizing:

  • Apply a low-phosphorus native fertilizer in early spring.

  • Avoid overfeeding—too much nitrogen can encourage weak growth.

Pruning:

  • Minimal pruning needed unless shaping is required.

  • Remove damaged, crossing, or low lateral branches during the first 2–3 years to develop a strong structure.

Pest & Disease Monitoring:

  • Generally pest-resistant, but monitor for lerps or psyllids on young leaves.

  • Improve airflow around the tree by maintaining open space.

Mulching Maintenance:

  • Replenish mulch annually to keep weeds down and roots insulated.

  • Keep mulch a few centimeters away from the base of the trunk to prevent rot.

Staking:

  • Only stake if necessary (e.g. windy sites). Remove stakes after 12 months to allow trunk strengthening.

Growing Your Eucalyptus Grandis - Flooded Gum in Various Soil Types

How to Grow in Different Soil Types

Well-drained, fertile soils are preferred.

  • Sandy Soil: Add compost to improve nutrient retention.
  • Clay Soil: Not ideal unless well-drained—improve with gypsum and organic matter.
  • Loamy Soil: Ideal—supports vigorous root development.
  • Acidic Soil: Tolerates mildly acidic pH; avoid high alkalinity.
