Which Longview Stumps Sprout Back and Which Do Not
Pines Are Done
Loblolly and shortleaf pine do not resprout from a cut stump. Conifers of this type carry no dormant buds in the root collar capable of producing new shoots, so once the trunk is severed the root system has no way to rebuild a canopy and simply dies back. A pine stump is therefore a decay problem and a tripping hazard, never a regrowth problem.
Sweetgum Is the One That Fights
Sweetgum responds to removal by sending up root suckers, often across a surprising radius and often for several seasons. Homeowners frequently discover shoots appearing in lawn ten or fifteen feet from where the tree stood, because the suckering comes from the spreading roots rather than only the stump. Grinding the stump alone does not stop it.
Water Oak, Hackberry and the Rest
Water oak and hackberry both resprout readily from a cut stump, throwing a cluster of vigorous shoots from the collar within a season. Post oak is far less inclined to. The practical point is that a hardwood stump should be assumed capable of regrowth unless you know the species, because the cost of assuming otherwise is two years of mowing over shoots.
What Actually Stops It
Repeated removal of shoots eventually exhausts the stored energy in the roots, but it takes persistence and the roots usually outlast enthusiasm. A grind that goes below the root collar removes the tissue most shoots come from and settles the matter for stump sprouts, though it does not address sweetgum suckers arising further out. For those, patience with the mower is the ordinary answer.
Timing Matters More Than People Think
A stump cut in late winter has a full growing season of stored reserves behind it and sprouts hard. One cut late in the season has less to spend and responds more weakly. This is a small effect next to species, but where you have a choice on a known suckering hardwood, later is easier to manage.
