If you’re grinding a sweetgum stump to be done with those spiky gumballs, know this up front: the stump isn’t the only thing that sprouts. Sweetgums send up shoots from their shallow surface roots, and a stump that’s only ground at the crown can still throw new sprouts that grow into little trees – which, given a few years, make their own gumballs. Grinding the surface roots, not just the trunk, is what actually ends the cycle.
Why sweetgums are a special case
Most yard trees, you grind the stump and you’re finished. Sweetgums are in the same club as Bradford pear here – they sucker. They’ve got big, shallow, ropey roots that run out sideways from the trunk, close to the surface, and any of them can push up a new shoot after the tree’s gone. Leave those roots full of energy and you’re mowing over baby sweetgums next summer.
So on these we take the stump down 4–6 inches below grade and knock down the surface roots and any sucker points radiating out from it. Same approach as the pears – more on that work is on our root removal page.
The honest part about the gumballs
Grinding stops the tree from making new gumballs. It does nothing about the ones already carpeting your yard. Those you’re raking, blowing, or running over with the mower regardless – no machine changes that. What we can promise is that once the stump and surface roots are ground out, no new sprouts means no new supply.
- Grinding the stump alone can still leave you fighting root sprouts.
- Sweetgum roots are shallow and wide, so there’s often more surface root to deal with than the trunk size suggests.
- Existing gumballs on the ground still need cleaning up the old-fashioned way.
One more thing worth knowing: because the roots are so shallow and wide, a big sweetgum can have surface roots lifting a lawn or walkway several feet from the trunk. We can grind those flush too while we’re there.
Tired of the spiky things? Text us a photo of the stump – set something next to it for scale – and point out any surface roots you can see. We’ll usually get a price back the same day and tell you how much root grinding it’ll take to keep it from coming back.
