How to plant it

General steps for this plant. Save a garden and these become specific to your location, soil and light.

  1. Step 1When to plant

    Plant during November to March, whenever the ground is not frozen or waterlogged.

    Woody plants establish best planted while dormant, so roots grow before the first summer.

  2. Step 2Where to put it

    Choose a position in full sun for most of the day. Allow 6 m of room around it — mature spread is 6 m and mature height 6–10 m.

    Light in your garden is not answered, so this is the plant's own requirement.

  3. Step 3Preparing the ground

    Dig a hole twice as wide as the root ball and no deeper, loosen the sides, and plant so the top of the root ball is level with the surrounding soil.

    Soil is not answered. This plant grows in free-draining, average conditions.

  4. Step 4Watering while it establishes

    Water thoroughly at planting (20–30 litres), then only when the top few centimetres of soil are dry, through the first two full growing seasons.

    Even a drought-tolerant plant (5/5 here) only becomes drought-tolerant once established.

  5. Step 5Mulch

    Spread 5–7 cm of composted bark or garden compost around the plant, keeping it clear of the stem.

    Mulch cuts water loss and suppresses weeds through the first summer, when losses are most likely.

  6. Step 6The first year

    Check it after strong wind and in long dry spells. Little else is needed.

    Maintenance level on the plant record is low.

  7. Step 7What to watch for

    Resents humidity and heavy wet soils.

    Taken from the plant record and your measured climate figures, not from a general description.

Spacing: about 6 m apart — roughly 1 plant for every 10 m² if planted as a group.

What this guide could not use

  • No location saved, so planting times are general rather than local.
  • Soil moisture is not answered, so soil preparation is general advice.
  • Light is not answered, so the position below is the plant's own preference.
  • Whether you can water is not answered, so watering assumes hand watering.

Corymbia ficifolia, commonly known as red flowering gum, is a species of small tree that is endemic to the south-west of Western Australia. It has rough, fibrous bark on the trunk and branches, egg-shaped to broadly lance-shape adult leaves, flower buds in groups of seven, bright red, pink or orange flowers and urn-shaped fruit. It has a restricted distribution in the wild but is one of the most commonly planted ornamental eucalypts.

These figures come from the demonstration dataset kept for testing and as a fallback when the measured climate service is unavailable. They are representative, not observed, and are never presented as validated live data.
