Stump grinding vs stump removal: which one do you need?
They sound like the same job and they are not. Grinding shaves the stump down below the surface and leaves the roots where they are. Removal takes out the stump and its main roots and refills the hole. Which one you need depends entirely on what is going on that spot next.
By Harry Fauver, founder of Tree Service Beaverton. Updated September 2026.
What each one leaves behind
A stump is mostly below ground. What you see in the lawn is the top of a flare that widens for a foot or two beneath the surface before it divides into roots as thick as your leg. Grinding deals with the part you can see and a few inches more. Removal deals with all of it.
Neither is better. They answer different questions. If the only thing you want from the spot is grass, digging a hole the size of a hot tub to get it is pointless. If you want a patio, leaving a cubic yard of wood to rot under it is a mistake that shows up a few years later as lifted pavers and a cracked slab.
Factor by factor
Pick what matters to you.
What stays in the ground
Grinding: the base of the stump below grind depth, all of the roots, and a bowl of grindings, which are wood chips mixed with soil. They rot over five to fifteen years, and the surface settles as they go.
Removal: only the outer roots, cut off cleanly at the edge of the hole. Nothing is left under the spot itself.
The hole
Grinding: a shallow bowl, 4 to 12 inches deep and a little wider than the stump. It is filled the same day with chips or topsoil.
Removal: two to three times the width of the stump and 2 to 3 feet deep. It is backfilled with soil in layers, each one compacted, and produces a pile of spoil about twice the volume of the hole.
Time and disruption
Grinding: usually under an hour per stump once the machine is in place. The grinder fits through most gates, and the lawn around it is barely marked.
Removal: half a day to a day. It may need a compact excavator, which needs a wider route in, and the area around the hole will need repair afterward.
Will it grow back?
Grinding: conifers never resprout. Maple, cottonwood, willow, cherry, plum and locust can send up suckers from the remaining roots for a season or two. Mowing or cutting them off is enough, since without leaves the roots starve.
Removal: very little regrowth, because the root crown, where most buds are, is gone.
What you can do with the spot
Grinding: lawn, ground cover, perennials, shrubs with a deep grind, mulch or a gravel path where a little settling doesn't matter.
Removal: anything, including pavers, poured concrete, footings, fence posts, retaining walls and a new tree in the same position.
Utilities
Both need an 811 locate, which Oregon law requires at least two business days ahead. Removal goes deeper and wider, so it meets more lines. Within 24 inches of a marked line the digging is done by hand. Private lines, such as sprinkler pipe, lighting wire and septic systems, are not marked by the locators and are yours to point out.
Match the method to the project
- Lawn. Standard grind, 4 to 6 inches. Haul the chips, fill with topsoil, mound it slightly and seed.
- Planting bed or shrubs. Deep grind, 10 to 12 inches, so new roots grow into soil and not into wood.
- A new tree. Plant it a few feet away and grind the old stump. If it has to go in exactly the same place, as replacement street trees often do, take the stump out.
- Fence. If a post lands on the stump, remove it. If the post spacing can shift a foot, grind.
- Patio, path or pavers. Remove. The gravel base needs firm ground.
- Shed, deck footing, addition or retaining wall. Remove, and ask your builder what compaction they need.
- Driveway or parking pad. Remove. Vehicle loads find every soft spot.
- The tree died of root disease. Remove, or grind deep and chase the roots. Honey fungus and laminated root rot live on in dead stumps and roots and can spread to nearby plants.
The stump removal page has a chooser that walks through the same decision, and stump grinding explains grind depths.
The third option: leave it
Nothing says a stump has to go. In a back corner, a stump cut low is a seat, a plant stand or habitat, and a conifer stump will sit there quietly for decades. Leaving it is also the right call on a steep bank, where the roots are holding the slope together.
Reasons not to leave one: it is in the lawn and in the way, it is a species that resprouts, the tree died of a root disease, or it is close enough to the house for carpenter ants to be a concern.
Two shortcuts are worth skipping. The granular stump removers sold at hardware stores are mostly potassium nitrate, which speeds up rot a little over several years and no more. And burning a stump out is not an option in the urban area, where backyard burning is restricted, quite apart from the risk of a root fire that smolders underground for days.
Afterward: soil, settling and replanting
After grinding, don't seed straight into the grindings. Rotting wood ties up the nitrogen that seedlings need and you get a thin, yellow patch. Rake the chips out, fill with topsoil, mound it an inch or two above the lawn and seed in early fall or spring. Expect to top it up once.
After removal, the fill is compacted in layers 6 to 8 inches thick. Under anything built, the fill is mineral soil or gravel, never chips, sod or organic topsoil. In lawn, the surface is left slightly crowned, because even compacted soil settles a little in its first wet winter. In Beaverton's slow-draining clay, removal is best done in the dry season, since a hole dug in January fills with water overnight.

Questions people ask
Is stump grinding or stump removal better?
Neither is better in general. Grinding is right for lawns and planting beds. Removal is right where something will be built or a new tree planted on the same spot, because wood left in the ground rots and the surface sinks.
Does stump grinding remove the roots?
No. Grinding takes the stump down a few inches below the surface, deeper on request, and can follow surface roots outward. The main roots stay in the soil and decay over several years.
Can I pour concrete over a ground stump?
It isn't wise. The remaining wood and the grindings rot and shrink over the following years, a void forms underneath, and the slab cracks or sinks along the old roots. Have the stump fully removed and the hole compacted first.
How long does it take a stump to rot naturally?
In the Beaverton area, from several years for alder and maple to decades for Douglas-fir and western redcedar, which are rot resistant. Products sold to speed it up make only a small difference.
Do I need to call 811 before stump work?
Yes, for both grinding and removal. Oregon requires a utility locate at least two business days before digging. We request it for every job. You point out private lines, such as irrigation and lighting, which the locators don't mark.
