Here's the short answer up front. Stump grinding chews the stump into wood chips 6 to 12 inches below grade and backfills the hole with the grindings — for most residential stumps, the machine is on and off your property in under an hour. Stump removal digs the entire root ball out of the ground with excavation equipment, typically costs several times more, and leaves a crater plus torn-up turf where the roots ran. Grinding is the right call in roughly 90% of cases. Full removal earns its price in one situation: when something has to occupy that exact piece of ground — a foundation, a slab, a utility line, or a new tree planted in the same hole.
That's the whole decision for most Spokane-area homeowners. The rest of this article covers the details worth knowing before you book either one: how each method actually works, a decision table you can scan in ten seconds, what happens under your lawn in the years after grinding, and one honest local complication — the rocky ground much of Spokane County sits on.
How each method actually works
Grinding uses a purpose-built machine — anywhere from a walk-behind unit that fits through a 36-inch gate to a tracked machine for big stumps — with a spinning wheel of carbide teeth. The operator sweeps the wheel side to side across the stump, shaving it into chips, working down until the stump is 6 to 12 inches below the surrounding grade. The chips mix with soil and backfill the hole, usually leaving a low mound that settles over time. Surface roots that snake across the lawn can be ground too; that add-on is called a root chase, and it matters for trees like maples and poplars whose roots run shallow and wide. You can see what's included in a standard visit on our stump grinding page.
Full removal is an excavation job. The crew digs around the stump, severs the major lateral roots, and pulls the entire root ball out of the ground — for a mature tree, a mass of wood and soil that can be several feet across and surprisingly heavy. Then the root ball has to be hauled away and the crater backfilled with imported soil. It's more machine time, more labor, more hauling, and more restoration afterward, which is why it typically runs several times the price of grinding the same stump. The yard damage is real: expect equipment tracks and a much larger disturbed area than the stump's footprint.
The decision table
| Your situation | Grind it | Dig it out | |---|---|---| | You want lawn back where the tree stood | Yes — grind, top with soil, seed or sod | Overkill | | Cost is the deciding factor | Yes — a fraction of removal cost | No | | The tree won't be replaced in that spot | Yes | No | | You're building over the spot (addition, garage, shop slab) | No — buried wood decays and settles under footings | Yes — full removal is standard before construction | | Stump sits in a future driveway, patio, or utility trench line | No | Yes | | You're replanting a new tree in the exact same hole | Usually not enough | Yes — or a deep grind plus root chase, then clean backfill | | Clearing many stumps from a build site or acreage | Sometimes | Usually — done as part of land clearing with excavation equipment already on site |
That last row is worth a note. If you're taking out one backyard stump, grinding wins on price almost every time. But if you're clearing a building lot or several acres — the kind of work happening on rural parcels across north Spokane County right now — stumps usually come out whole, because the excavator is already there and buried root balls can't be left under anything structural.
What happens under the lawn after grinding
Grinding doesn't make the stump vanish — it converts it into a hole full of wood chips and leaves the root system in the ground. Three things follow from that, and knowing them ahead of time saves you a callback:
The chips settle. Freshly ground chips mixed with soil sit higher than grade, then compact and decompose over one to two seasons, often ending as a shallow depression. The fix is cheap: rake off the excess chips (they make fine mulch for beds), backfill with topsoil, and re-seed. Plan on topping it up once the following year.
Grass over the spot may yellow at first. Decomposing wood ties up soil nitrogen as microbes break it down — gardeners call it nitrogen tie-up. Grass seeded straight into chip-heavy soil often comes in pale and thin. Removing most of the grindings, backfilling with real soil, and giving the new grass a nitrogen feeding solves it.
The roots decay in place — unless they're still alive. For ponderosa pine and most conifers, the root system simply dies and rots over a period of years, harmlessly. But if you see sucker shoots popping up in the lawn months after grinding, that's not the stump growing back — it's live roots, common with poplars, willows, black locust, and some maples. Suckers mean the grind needed to go deeper at the stump, and the remaining roots are still burning stored energy. Repeated mowing exhausts them; persistent cases call for a deeper re-grind.
Can you plant over a ground stump?
This is the most common follow-up question, and the honest answer is: beside it, not on it. The ground-out zone is a pocket of decaying wood, tied-up nitrogen, and old roots — a tough start for a young tree. Plant the replacement a few feet off the old trunk location and it'll establish far better. If the new tree genuinely must go in the same spot, that's the replant-in-place case from the table above: deep grind with a root chase or full removal, then backfill with clean soil before planting.
The honest Spokane catch: what's under your grass
Here's the local trade-off that generic national articles skip. Much of the Spokane area sits on gravelly glacial outwash left by the Ice Age Missoula Floods — sand, gravel, and cobbles — and in places like the South Hill and the scabland fringes, soil runs thin over Columbia River basalt bedrock. Grinder teeth are carbide, but rock still wins: cobbles and shallow basalt can force an operator to stop above the usual 6-to-12-inch depth, and nobody can grind into bedrock. A reputable estimator will tell you up front what depth your ground realistically allows — ask the question before you book, especially on rocky lots.
The same geology shapes replanting advice. Around Mead, for example, the Garrison-series gravelly loams drain fast and anchor big conifers shallowly — one reason Fairwood's 60-to-100-foot ponderosas come down in windstorms in the first place. If you're replacing a tree on ground like that, offset the new planting from the old root zone, and commit to deep, infrequent watering through the first summers, because fast-draining gravel gives young roots little margin. And on Green Bluff, where orchard rows get renewed tree by tree, replanting in the same row spacing is exactly the situation where a deep grind with root chase or full removal earns its cost.
Spring is stump season here — get in the queue
Spokane's storm calendar writes the stump calendar. The November-through-January windstorm and snow-load season drops trees across the county, winter removals get cut to grade, and by spring there's a backlog of stumps waiting on thawed ground. If you've got one (or a yard full), the choice is usually simple: grind it, restore the lawn, and keep the price difference in your pocket — unless you're building or replanting in that exact spot.
