Stump Grinding in Madison, WI

Stump grinding uses a machine with a toothed wheel that chews a stump into chips, starting at the top and working down below the soil line. It is faster and far less destructive than digging a stump out, and it leaves the deep roots to rot in place. For most Madison yards it is the last step after a removal: the tree is gone, and the stump is in the way of a mower, a new garden bed, a patio or a replacement tree. Some homeowners grind the same day as the removal; others call us years later about a stump an earlier owner left behind.

Utility marking comes first

Grinding goes into the ground, so underground lines have to be located first. In Wisconsin that means a request to Diggers Hotline, and MGE asks for at least three business days of notice before digging projects. Gas service lines, buried electric to a garage, invisible dog fences and irrigation lines are all common in Madison yards. Marks show where a line runs but not how deep it is, so we grind carefully near any flag. Private lines such as a cable to a backyard shed are not located by the hotline, so tell us about any you know of.

How deep and how wide

How far down we grind depends on what comes next. For grass seed, a few inches below grade is usually enough. For a new tree, a patio base or a fence post, we go deeper and wider so the new work is not sitting on old wood. Surface roots that run out from the stump and lift the lawn can be ground along their length too, which costs more but leaves a smoother yard. We agree on depth in the quote so there is no surprise.

Fresh oak stumps in spring

The Wisconsin DNR notes that the beetles that spread oak wilt are drawn to fresh wounds and recently cut oak stumps. If an oak comes down during the April-to-July high-risk period, the stump is part of the risk. Grinding it soon after the cut, or treating the cut surface right away, removes much of that attraction. Because oak roots graft with neighbors, an oak that died of oak wilt may also call for breaking those root connections before nearby oaks are cut, which is a separate decision we talk through with you.

Chips and the hole left behind

A ground stump leaves a mound of chips mixed with soil, often more than people expect. You can keep it to fill the hole and settle over a season, spread it as mulch around shrubs, or have us haul it off and backfill with topsoil. Chips from a diseased tree should be kept away from healthy trees of the same species. Grass seed does poorly in pure chips, so if you want lawn there, plan on removing most of the chips and adding soil.

Terrace stumps

If a city tree was removed from the terrace in front of your house, the stump is the city's job. Madison's Urban Forestry crews remove terrace stumps with their own equipment after utility marking, and the city notes that stumps from late-fall removals may wait until spring. We grind only stumps on private property.
