About Eucalyptus Grandis - Flooded Gum

Eucalyptus grandis, commonly known as Flooded Gum, is a majestic, fast-growing Australian native tree prized for its striking smooth white trunk and upright form. Growing 30–50 metres tall, it makes a bold statement in large-scale landscapes, forestry, and revegetation projects where rapid canopy development and vertical presence are essential.

The smooth, powdery white bark peels seasonally to reveal soft grey or pink undertones, adding year-round visual interest. Its long, lance-shaped green leaves form an open, airy canopy that provides filtered shade and supports native wildlife. Summer brings clusters of small white flowers that attract bees and pollinators, boosting biodiversity.

Flooded Gum thrives in deep, fertile, well-drained soils, especially in moist environments such as creeks and floodplains. It is not suited for confined or dry landscapes due to its size and water needs, but it excels in rural properties, erosion control, and carbon planting projects.

This tree looks excellent when you want a commanding, elegant feature that combines ecological value with rapid growth and low maintenance — perfect for bold, naturalistic landscapes.

Key Information to Know

Evergreen / Deciduous

Eucalyptus Grandis - Flooded Gum is an Evergreen (foliage year round) Tree

Mature Height & Width

Mature Height: 40m - 60m Approximately

Mature Width: 10m – 15m

Eucalyptus Grandis - Flooded Gum is expected to grow Approx. 0.8 – 1.2 m per year.

Frost Tolerance

Is Eucalyptus Grandis - Flooded Gum frost tolerant?

Eucalyptus Grandis - Flooded Gum is Frost Hardy – Survives heavy and frequent frost without damage.

Flowering Information

Eucalyptus grandis produces clusters of small creamy-white fluffy flowers from late spring into summer. These soft blooms sit along the branchlets and create a subtle seasonal highlight that pairs with its tall, straight trunk and glossy green canopy.

Native Information

Is Eucalyptus Grandis - Flooded Gum an Australian Native? Yes

Eucalyptus Grandis - Flooded Gum is Native to Eastern Australia, from northern New South Wales to Queensland, where it grows naturally along river flats, moist valleys, and coastal forests.

Wildlife Value

Its nectar-rich flowers attract honeyeaters, native bees, butterflies and a wide range of beneficial insects. The tall canopy provides excellent perching, nesting and shelter opportunities for small birds, while the shedding bark supports insects and microfauna that enrich native biodiversity.

Sunlight Information

Eucalyptus Grandis - Flooded Gum will thrive best in:

Full Sun

Preffered Soil

Eucalyptus grandis performs best in deep, well-drained loam or sandy loam soils and prefers slightly acidic to neutral conditions. It can struggle in heavy clay, shallow soils or waterlogged ground unless improved with organic matter and coarse material to enhance drainage and root depth. Keep soil evenly moist during establishment, then maintain deep, regular watering as it matures to support its fast growth, tall straight form and reliable canopy performance.

Planting, Spacing & Care

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.

Hedging & Screening: Not suitable.

Feature Tree: 6 m – 10 m apart for full-size forest tree growth.

Avenue Planting Trees: 8 m – 12 m for spacious landscapes.

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.

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.

Eucalyptus Grandis - Flooded Gum is expected to grow Approx. 0.8 – 1.2 m per year.
