The sweetgum tree is one of the most recognizable trees in the eastern United States. It has star-shaped leaves, brilliant fall color and spiky brown seed balls that cover lawns and driveways every winter. Homeowners tend to love it in October and regret it in February. This guide explains how to identify a sweetgum tree, how big it gets, the problems it causes, which varieties don’t drop gumballs, when removal makes sense and what removal typically costs.
What Is a Sweetgum Tree?
Sweetgum (Liquidambar styraciflua) is a large deciduous tree native to North and Central America. According to the USDA Forest Service Silvics Manual, it grows from Connecticut south through the East to central Florida and eastern Texas, west to Missouri, Arkansas and Oklahoma, with scattered populations in Mexico and Central America. It grows in USDA hardiness zones 5 to 9, and UF/IFAS Extension lists it up to zone 10A.
The name comes from its sap. Virginia Cooperative Extension notes that the sap is sweet-tasting and gummy. Sweetgum is also an important timber tree: NC State Extension lists furniture, cabinetwork, veneer, plywood and pulpwood among its uses.
How to Identify a Sweetgum Tree
Sweetgum is easy to recognize once you know what to look for:
- Leaves: Star-shaped with five (sometimes seven) pointed lobes, finely toothed, 4 to 6 inches long, glossy dark green on top (UF/IFAS).
- Fall color: Yellow, orange, red, burgundy and purple, often all on the same tree.
- Gumballs: Round, spiny brown seed balls about 1 to 1½ inches across, hanging on long stems.
- Twigs: Many branches develop corky “wings” or ridges along the bark (Virginia Cooperative Extension).
- Shape: Pyramid-shaped when young, becoming rounder or oval with age.
Sweetgum vs. Maple
People often mix up sweetgum and maple because both have lobed leaves and bright fall color. Three differences make it simple:
| Feature | Sweetgum | Maple |
|---|---|---|
| Leaf arrangement | Alternate (one leaf per node, staggered) | Opposite (leaves in pairs) |
| Leaf shape | Five-pointed star, lobes fairly even | Three to five lobes, often with deep notches |
| Seeds | Spiky round gumballs | Winged “helicopter” seeds (samaras) |

Sweetgum Tree Size and Growth Rate
Sweetgum is a big tree. UF/IFAS Extension gives a mature height of 60 to 75 feet with a 35 to 50 foot spread, and NC State Extension says it can reach 60 to 100 feet, with a trunk 4 feet or more across. In smaller yards and cities, Virginia Cooperative Extension lists a more typical 50 feet tall and 30 feet wide.
It grows at a moderate to rapid pace. The USDA Forest Service reports young trees on good sites adding about 2 feet a year. It’s also long-lived: sweetgum starts producing seed at 20 to 30 years old and keeps producing until at least 150 years of age, according to the Silvics Manual.
That size matters when you plant one, and when you need one removed. Measure your tree from the ground with the tree height calculator and its trunk with the DBH calculator.
Why People Plant Sweetgum
Sweetgum has real strengths, which is why so many were planted as street and shade trees:
- Fall color that rivals maples
- Strong branches. UF/IFAS Extension says sweetgum branches are resistant to breakage, and the tree needs little pruning.
- Few serious pests. Bagworms, webworms, caterpillars and scale insects can show up, but UF/IFAS says the tree is rarely attacked by pests.
- Wildlife value. NC State Extension notes that American goldfinches eat the seeds in winter, and the tree hosts the caterpillars of the imperial moth and the hickory horned devil.
- Adaptable. It tolerates clay, sand and loam, and wet to well-drained soils.
Common Sweetgum Tree Problems
1. Gumballs Everywhere
The spiky seed balls are the number one complaint. NC State Extension says they mature to dark brown in fall, usually hang on through winter and fall from December through April. UF/IFAS calls them a litter problem, especially on hard surfaces where people can slip, and Virginia Cooperative Extension calls the litter “significant” in many landscapes.
Gumballs are hard and spiny. They are painful underfoot, roll under shoes on steps and driveways, and can be thrown by a lawn mower.
2. Surface Roots That Lift Sidewalks
Sweetgum roots are a common reason homeowners call a tree service. UF/IFAS Extension warns that sweetgum can form large surface roots that lift curbs and sidewalks, and recommends planting it 8 to 10 feet or more from curbs. NC State describes the root system as shallow, and Virginia Cooperative Extension says the tree doesn’t do well where roots lack room to spread.
If your sweetgum is close to a driveway, patio or house, check our guide to tree distance from a foundation.
3. Yellow Leaves in Alkaline Soil
Sweetgum struggles in high-pH soil. Both UF/IFAS and Virginia Cooperative Extension list iron chlorosis (yellow leaves with green veins) in soils above pH 7. UF/IFAS recommends planting it only where the soil pH is 7 or lower.
4. Canker and Dieback
UF/IFAS notes that canker diseases can cause sunken, bleeding areas on the trunk, with no chemical control, and that severely infected trees die. In the South, leader dieback can follow drought or construction damage to the roots. Leaf spots also occur but aren’t serious.
5. Too Big for the Space
Many sweetgums were planted as small trees in small yards. At 60 feet or more, a mature tree can overhang roofs, power lines and neighbors’ property.
Fruitless Sweetgum Varieties
If you love the tree but not the gumballs, plant a fruitless cultivar. UF/IFAS Extension and Virginia Cooperative Extension both list ‘Rotundiloba’ as fruitless. It has rounded leaf lobes instead of pointed ones and a narrow, pyramid shape. Virginia Cooperative Extension warns that ‘Rotundiloba’ can sometimes revert to the regular form, so prune out any branches with pointed leaves.
Other cultivars mentioned by UF/IFAS and NC State Extension:
| Cultivar | Notable trait |
|---|---|
| ‘Rotundiloba’ | Fruitless, rounded leaf lobes |
| ‘Moraine’ | Reputed to be the most cold hardy |
| ‘Burgundy’ | Burgundy-red fall color, less cold hardy |
| ‘Palo Alto’ | Pyramid shape, bright orange fall color |
| ‘Gumball’ / ‘Oconee’ | Dwarf forms, around 15 feet tall |
When Should You Remove a Sweetgum Tree?
Sweetgum is a healthy, strong-wooded tree, so most aren’t removed because they’re dangerous. Consider removal when:
- Roots are lifting a sidewalk, driveway or patio, or are close to the foundation.
- The tree has bleeding cankers on the trunk or major dieback in the crown.
- It’s planted too close to the house or under power lines and has outgrown the space.
- Gumballs are a real hazard, for example on steps, a pool deck or a path an older person uses every day.
- It’s dead, storm-damaged or leaning.
If the tree is healthy and only the litter bothers you, trimming and regular cleanup may be enough. Our guide on when to remove a tree instead of treating it walks through the decision, and you should check whether you need a permit, especially for large or street trees.
How Much Does It Cost to Remove a Sweetgum Tree?
Because sweetgums grow tall, removal usually falls in the medium-to-large price range. Based on Lawn Love’s 2026 national data, a sweetgum between 30 and 60 feet typically costs $435 to $870 to remove, a mature 60 to 80 foot tree $870 to $1,160, and a very large tree over 80 feet $1,160 to $2,000. Expect more if the tree hangs over the house, sits near power lines or has to be taken down in sections. Stump removal is usually extra, about $180 to $525.

Watch for Root Sprouts After Removal
Sweetgum sprouts readily from its roots. The USDA Forest Service Silvics Manual notes that after logging it’s not uncommon to find 40 or more stems on the root system of a single tree. After removal, grind the stump and keep mowing or cutting any shoots that come up. Read what happens to roots after stump grinding and how to kill a tree stump for your options.
Tips for Living With a Sweetgum
If you’re keeping your tree:
- Rake or sweep gumballs off walkways, steps and driveways regularly from late fall through spring.
- Mow carefully. Clear gumballs from the lawn before mowing so the mower doesn’t throw them.
- Don’t pile soil over surface roots. It can harm the tree. Mulch the root zone instead.
- Prune in winter if needed, as Virginia Cooperative Extension advises.
- Plant new sweetgums well away from curbs and paving: UF/IFAS suggests 8 to 10 feet or more. Use the tree spacing calculator and our guide on how far apart to plant trees.
Sweetgum Tree FAQs
Are sweetgum trees messy?
Yes. The spiky gumballs fall from December through April and are hard, painful to step on and slippery on hard surfaces. Fruitless cultivars like ‘Rotundiloba’ avoid this.
Are sweetgum tree roots invasive?
Sweetgum roots can form large surface roots that lift curbs and sidewalks. Extension services recommend planting it at least 8 to 10 feet from curbs and paving.
How tall does a sweetgum tree get?
Usually 60 to 75 feet with a 35 to 50 foot spread, and up to 100 feet on good sites. In yards it’s often closer to 50 feet tall.
How long do sweetgum trees live?
Sweetgum is long-lived. The USDA Forest Service notes it produces seed until at least 150 years of age.
How much does it cost to remove a sweetgum tree?
Most mature sweetgums cost about $870 to $1,160 to remove, based on 2026 national data for 60 to 80 foot trees. Smaller trees cost less, and very large or hard-to-reach trees can cost $2,000 or more, plus stump removal.
Is there a sweetgum tree without gumballs?
Yes. The cultivar ‘Rotundiloba’ is fruitless and has rounded leaf lobes.
The Bottom Line
A sweetgum tree is strong, long-lived and beautiful in fall, but its gumballs and surface roots make it a poor fit for small yards and spots next to paving. If yours is healthy, regular cleanup may be all you need. If roots are lifting concrete or the tree has outgrown its space, plan removal, grind the stump and watch for root sprouts.
