ABOUT

Commonly known as urn gum, Eucalyptus urnigera is an appealing evergreen tree recognized by its smooth, cream-colored bark that often peels in ribbons to reveal greyish patches underneath. The foliage consists of oval or heart-shaped juvenile leaves which are a bright, glossy green and transition to more elongated and sickle-shaped adult leaves as the tree matures. During its flowering season, it displays white flowers which are small and arranged in clusters. The flowers give way to the urn-shaped seed capsules that are woody and can persist on the branches. The overall appearance conveys a picturesque quality, commonly found in cold, temperate climates, and it adds an elegant touch to the landscape with its pale bark and contrasting green foliage.

Pruning
  • water dropWater

    The Eucalyptus urnigera, commonly known as Urn Gum, prefers to be kept in well-drained soil and should be watered thoroughly, but infrequently. Initially, water the young trees once a week with about 1 to 2 gallons, depending on the size of the tree and the weather conditions. Once established, they are fairly drought tolerant and will require less frequent watering, about once every two to four weeks or even less often, depending on the climate. It is important not to over-water as it can lead to root rot. Always check the soil moisture before watering; the soil should be dry a few inches down before you water again.

  • sunLight

    Urn Gum thrives best in full sunlight, receiving at least six hours of direct, unfiltered sunlight per day. It is ideal to position the tree in a location where it gets ample morning light and some partial shade in the afternoon, especially in hotter climates. However, Eucalyptus urnigera can tolerate and do well in constant full sun exposure throughout the day.

  • thermometerTemperature

    Urn Gum prefers a temperate climate and can tolerate a temperature range between 20°F and 90°F. Frost-hardy, the Urn Gum can survive short periods of colder winter temperatures down to about 10°F but sustained cold can be detrimental. The ideal temperature for the Eucalyptus urnigera is between 60°F and 80°F, which promotes the best growth and health for the tree.

  • scissorsPruning

    Pruning the Urn Gum tree is generally done to shape the tree, remove dead or damaged limbs, and encourage healthy growth. Pruning should be done in late winter or early spring before new growth begins. It's recommended to prune the tree every two to three years, removing no more than 25% of the tree's canopy at a time to maintain its health and structure. Always use clean and sharp pruning tools to make clean cuts.

    As needed

  • bambooSoil

    Urn Gum prefers well-drained, slightly acidic to neutral soil with a pH of 5.5 to 7.0. A mix of sand or perlite, peat, and loamy soil in equal parts can provide the right texture and nutrients for healthy growth. Ensure the potting mix is airy and does not retain excessive water to prevent root rot.

  • plantRepotting

    Urn Gum should be repotted every 2-3 years or when it becomes root-bound. Younger plants may need repotting more frequently to accommodate their rapid growth, while older, established trees may require less frequent repotting.

  • water dropsHumidity & Misting

    Urn Gum thrives in environments with moderate to low humidity levels. These plants are adapted to withstand drier conditions and do not require high humidity to grow well, replicating their native habitat in Tasmania.

  • circleLife cycle

    Eucalyptus urnigera, commonly known as urn gum, begins its lifecycle with seed germination, which occurs in favorable conditions of warmth and moisture, often after fire has reduced competition from other vegetation. The seeds develop into seedlings, which undergo a period of rapid growth characterized by the production of juvenile foliage, which is distinct from adult foliage in shape and sometimes color. As the seedlings mature into saplings, they continue to grow, establishing a strong root system and beginning to form a characteristic woody trunk. When the plant reaches maturity, it produces adult leaves, which are more drought and fire resistant, and begins the reproductive phase by flowering. The flowers of the urn gum are hermaphroditic, containing both male and female reproductive parts, and after pollination by birds, bees, or other insects, they develop into woody, urn-shaped capsules that release seeds when mature. The life cycle can continue with the germination of these seeds, or the mature tree can resprout from its lignotuber or epicormic buds after events such as bushfires, which are common in its native Australian habitat.

      Spring to Summer

    • Eucalyptus urnigera, commonly known as urn gum, is commonly propagated from seed. The most popular method involves collecting seeds from mature capsules, which typically dry and release the seed in late summer or fall. To propagate urn gum from seed, the seeds should be sown on the surface of a well-draining seed raising mix, as they require light to germinate. A thin layer of the soil mix can be gently sprinkled over the seeds, but they should not be buried deeply. The container with the seeds needs to be kept moist, and ideally at a temperature of about 68°F (20°C), until germination occurs, which is usually within a couple of weeks. Once seedlings have developed several sets of leaves, they can be carefully transplanted into individual pots to grow on before being planted out in their permanent location.
