About Corymbia maculata

Corymbia maculata, the Spotted Gum, is a majestic Australian native renowned for its distinctive dappled bark. The smooth bark sheds in patches to create a striking spotted pattern in shades of grey, cream and pink, while the tall straight trunk and open canopy give it an unmistakable, sculptural presence.

Spotted Gum grows to 15-30 metres tall and 8-15 metres wide. The dramatic height and clean trunk make it best suited to large gardens, acreage, parks, and avenue planting, where it is also widely used by councils as a street tree. Creamy white flowers in winter and spring provide an important nectar source for native wildlife.

Spotted Gum is fast-growing, hardy, and drought tolerant once established, thriving across NSW, QLD, VIC and SA in full sun with well-drained soils. It tolerates mild frost and provides valuable habitat for honeyeaters, lorikeets, native bees, and possums.

Did you know? Corymbia maculata is the rootstock used to graft Corymbia ficifolia 'Wildfire', our compact red flowering gum. Its hardiness and adaptability are exactly why it makes such a reliable rootstock for grafted flowering gums in eastern Australia.

Planting Information

How To Plant Your Corymbia maculata Spotted Gum

Site: Choose a well-drained position in full sun to part shade with room for the canopy to develop.

Soil preparation: Enrich the planting area with quality compost and aged manure for a strong establishment phase.

Hole: Dig twice as wide as the root ball and the same depth.

Planting: Position level with the surrounding soil, backfill gently, firm in, then water deeply to settle the roots.

Recommended Planting Spacing For Your Corymbia maculata Spotted Gum

Feature tree: 3 to 4 metres apart to allow the full canopy and form to develop.

Pot or container: A 40 to 50 centimetre wide pot suits a single specimen for courtyards, entries and balconies.

Corymbia maculata Spotted Gum is expected to grow 1m to 1.5m per year (approx.).

  • Fast Growth Rate

Long Term Care For Your Corymbia maculata Spotted Gum

Watering: Water deeply twice weekly through the first 12 months. Once established, this is drought tolerant and only needs a deep soak during extended dry periods.

Mulching: Apply a 3 to 5 centimetre layer of organic mulch over the root zone in the garden, or a thin layer of decorative pebbles in pots, keeping it clear of the trunk.

Pruning: Minimal pruning required. Light tip prune in late winter to maintain shape, and remove lower branches as the tree grows to develop a clean feature trunk.

Fertilising: Apply a slow-release native blend in early spring and again in autumn. Avoid high-phosphorus formulations as a precaution.

Pest and disease: Hardy against most pests and diseases. Occasional inspection in warm humid conditions is all that's needed.

Planting Your Corymbia maculata Spotted Gum in Different Soil

Corymbia maculata performs best in well-drained sandy loam or loam with a slightly acidic to neutral pH. Adaptable to a wide range of soils when drainage is improved with organic matter.

Sandy soil: Free-draining and ideal. Mulch well to maintain consistent moisture.

Clay soil: Improve drainage with gypsum and organic compost before planting.

Loam: The preferred soil for steady root development and consistent growth.

pH: Slightly acidic to neutral preferred. Mulch with composted leaf litter to maintain levels naturally.

Plant Your Corymbia maculata Spotted Gum With:

Enriched Planting Mix (AO Certified)

Enriched Planting Mix is a certified organic blend of Pure Magic Compost, composted animal manure, gypsum, composted coarse bark and a wetting agent, bagged in 30L. It is built to be dug through existing garden soil at planting time rather than used on its own, and the gypsum is what sets it apart from a plain compost.

Gypsum helps break up heavy clay so water and roots can move through it, while the compost and manure return organic matter and nutrient to tired ground. The coarse bark holds structure and keeps air around the root zone, and the wetting agent keeps moisture in the soil longer after rain or watering.

Use it when planting trees, shrubs, roses, fruit trees and exotic garden plants, particularly into clay. Dig a hole twice the width of the pot and 7 centimetres deeper, then mix roughly one third planting mix through the excavated soil. Spread 7 centimetres of that improved soil in the base before setting the plant in.

Frequently Asked Questions

About Enriched Planting Mix

What is Enriched Planting Mix made from?

It is a blend of Pure Magic Compost, composted animal manure, gypsum, composted coarse bark and a wetting agent. Each part has a job. The compost and manure supply organic matter and nutrient, the gypsum works on clay structure, the bark keeps air around the roots and the wetting agent holds moisture in the soil.

What plants is it suitable for?

It suits exotic garden plants, including roses, ornamental and deciduous trees, fruit trees, shrubs and perennials, and it earns its keep most on heavy clay sites. It is a planting mix rather than a potting mix, so its job is improving soil at planting time. Phosphorus sensitive natives are the one clear exception.

Is it safe for natives?

No, not for the phosphorus sensitive ones. The composted animal manure in this blend lifts phosphorus well above what Proteaceae such as Banksia, Grevillea, Hakea and Protea will tolerate, and the result can be leaf burn, dieback and plant death. Use the Native Potting Mix for those species, or plant them into unimproved local soil.

Is it certified organic?

Yes. It is a certified organic product with no chemical additives, which is why the manure and compost in it are fully composted rather than raw. That makes it sound around fruit trees and vegetable beds, and it means you are adding genuine organic matter to your soil rather than a synthetic conditioner.

How much do I need?

Work on roughly one third planting mix to two thirds of the soil you dug out of the hole. For a shrub out of a 200 millimetre pot that is only a few litres. An advanced tree going into a large hole will take considerably more. Judge the quantity by the volume of the hole rather than the size of the plant.

Can I use it in pots?

It is not a potting mix and should not be used on its own in a container. The blend is designed to be diluted through garden soil, and used straight in a pot it holds too much water and settles badly. For containers, reach for a premium potting mix, or the native mix if you are potting natives.

Does it need to be watered in?

Yes. Water the plant well several hours before you plant it, then water thoroughly again once the hole is backfilled and the soil firmed down. That first deep watering settles the improved soil around the root ball and drives out air pockets. Keep the water up over the first few months while the roots establish.
