  • water dropWater

    The American Sweetgum 'Gum Ball' prefers consistent moisture and should be watered deeply every week to ten days during its growing season, depending on the weather conditions. Early morning watering is most beneficial, targeting the base of the plant to keep the foliage dry and minimize the risk of leaf diseases. Use enough water to soak the root zone, which may equate to 1 to 1.5 inches of water each time. During hot, dry periods, increase the frequency of watering but always allow the soil to dry out slightly between watering sessions. Reduce watering in the fall and winter when the tree is dormant.

  • sunLight

    The American Sweetgum 'Gum Ball' thrives best in full sun conditions, which means it should receive at least six hours of direct, unfiltered sunlight every day. It can tolerate partial shade, but for optimal growth and development of its fall foliage color, a location with full sun exposure is recommended. Planting it in an open area with abundant sunlight will help ensure the health and vibrancy of the tree.

  • thermometerTemperature

    The American Sweetgum 'Gum Ball' can tolerate a wide range of temperatures and can survive minimum temperatures down to around -10 to -20 degrees Fahrenheit. However, it grows best when the temperature is between 70 and 90 degrees Fahrenheit during the growing season. This tree is hardy in USDA zones 5 through 9, and it is essential to avoid planting it in locations where temperatures drop below its cold tolerance range.

  • scissorsPruning

    Prune the American Sweetgum 'Gum Ball' to maintain its round shape and remove any damaged or diseased branches. The best time to prune is in late winter or early spring before new growth begins. It's usually sufficient to prune this tree every two to three years, inspecting it annually for any necessary maintenance pruning. When pruning, make clean cuts and avoid leaving stubs to promote healthy regrowth.

  • circleLife cycle

    The American Sweetgum 'Gum Ball' starts life as a seed, which, after stratification, germinates in the spring. The seedling grows rapidly, developing into a young sapling with distinctive star-shaped leaves and a strong root system. As it matures over several years, it forms a rounded, compact crown, characteristic of the 'Gum Ball' cultivar. The tree reaches reproductive maturity, typically producing inconspicuous flowers that are followed by the notorious spiky fruit balls in the fall, which contain seeds for dispersal. As a deciduous tree, it displays a dramatic change of foliage color in autumn before shedding its leaves for winter dormancy. Over its lifespan, which can exceed 50 years under favorable conditions, it continues this annual cycle of growth, reproduction, and dormancy.

      Late Winter

    • The Liquidambar styraciflua 'Gum Ball', commonly known as the American sweetgum, is often propagated by seed or through hardwood cuttings. The most popular method of propagation for the American sweetgum is through hardwood cuttings, generally taken in late fall or early winter when the tree is dormant. For successful propagation, cuttings should be around 6 to 8 inches long and taken from healthy, mature trees. The cut end of the cutting is dipped in a rooting hormone to encourage root growth and then placed in a mixture of sand and peat to root. Maintaining adequate moisture and warmth will help the cuttings to develop roots over several weeks, after which they can be potted or moved to a nursery bed to grow until they are robust enough to plant out.
