Spectacular Fall Color with a Catch
The Sweetgum (Liquidambar styraciflua) is one of the most common native trees across metro Atlanta's forests and landscapes. It is celebrated for its spectacular fall color display, which can include shades of yellow, orange, red, and deep purple, often on the same tree. Growing 60 to 80 feet tall with a pyramidal to oval crown, sweetgums are attractive shade trees that contribute significantly to Atlanta's fall color show.
However, sweetgums have a notorious drawback: the spiny, golf-ball-sized seed capsules (gumballs) that litter the ground from fall through spring. These hard, prickly fruits are a nuisance on lawns, walkways, and driveways, making sweetgums one of the most frequently requested trees for removal. Despite this, sweetgums are ecologically valuable and provide excellent shade, so many homeowners choose to manage rather than remove them.
Identifying a Sweetgum
Sweetgum leaves are star-shaped with 5 to 7 pointed lobes, 4 to 7 inches across, and glossy dark green. They are aromatic when crushed, releasing a pleasant, resinous fragrance. The bark on mature trees is deeply furrowed with narrow, scaly ridges, gray to brownish-gray in color. Young twigs often develop distinctive corky, wing-like ridges along their length.
The fruit is the most recognizable feature: spherical, spiny capsules about 1 to 1.5 inches in diameter, hanging on long stalks. They start green, turn brown, and persist on the tree and ground for months. Each capsule contains small, winged seeds.
Growing Conditions in Atlanta
Sweetgums are extremely well-adapted to Atlanta's growing conditions. They tolerate clay soils, periodic flooding, and acidic conditions. They prefer full sun but handle partial shade. Their natural habitat includes floodplains and moist woodlands, making them perfectly at home in many Atlanta landscapes.
Common Problems and Diseases
Surface Roots are the most significant maintenance issue with sweetgums. Like red maples, sweetgums develop aggressive surface roots that can heave sidewalks, damage foundations, and create mowing difficulties. These roots are difficult to manage without harming the tree.
Fall Webworm frequently targets sweetgum in Atlanta, creating web-covered nests at branch tips in late summer. While unsightly, webworms rarely cause lasting damage to large trees. Small nests can be pruned out; large infestations generally require no treatment.
Leaf Spot diseases caused by various fungi can create brown or black spots on sweetgum foliage during wet seasons. The damage is typically cosmetic and does not require treatment in otherwise healthy trees.
Care and Maintenance
Sweetgums require minimal care once established. Water during extended drought and maintain mulch over the root zone. Prune in late winter to remove dead branches and manage structure. The gumball problem can be minimized by selecting fruitless varieties like 'Rotundiloba' for new plantings.
When to Call an Arborist
Contact an ISA-certified arborist if you need a sweetgum evaluated for removal or if you notice significant dieback, leaning, or root damage. If you want to remove a sweetgum, our team at EastLake Tree provides professional tree removal and stump grinding services throughout metro Atlanta.
Atlanta-Specific Tips
If you enjoy sweetgum for its shade and fall color but want to avoid gumballs, consider the fruitless cultivar 'Rotundiloba.' For existing sweetgums, regular gumball cleanup is the only practical solution. Avoid planting sweetgums near sidewalks, driveways, or patios where surface roots and gumballs create problems. These trees are excellent choices for naturalized areas and large open spaces where their drawbacks are less impactful.
