What is stump grinding?
Stump grinding uses a carbide-toothed grinding wheel to chew a tree stump down below grade, leaving wood chips and soil where the stump was. Taken deep enough, the spot can be reseeded, replanted, or built over. True Tree Service grinds stumps throughout Humboldt and Del Norte counties, including stumps left behind by other companies.
Why stumps in this climate can't just sit
In a dry climate, an old stump is an eyesore. On the wet North Coast, it is an active problem. Our rainfall turns dead stumps into sponges, and sponges into habitat.
Rot, fungus, and your healthy trees
Decaying stumps host root-rot fungi, including the pathogens that travel through root contact to healthy trees nearby. Removing the stump removes the reservoir. If you have lost one tree to root disease, grinding its stump is protection for the rest of the yard.
Carpenter ants and termites
A damp rotting stump is first-choice real estate for carpenter ants and dampwood termites, and a colony established ten feet from your house does not stay ten feet from your house. Grinding removes the nursery.
Sprouting and regrowth
Redwood, willow, cottonwood, and eucalyptus stumps do not accept defeat; they resprout, fast. Grinding through the crown of the stump takes out the growing points so you are not fighting the same tree twice.
Mowing, trips, and lost lawn
Every stump is a mower obstacle, a trip hazard, and a patch of yard you cannot use. Grinding gives the space back, level and ready for grass, garden, or fence line.
How stump grinding works
The grinder is a purpose-built machine with a spinning carbide wheel that sweeps across the stump, shaving it into chips from the top down. We grind below grade, chase the major surface roots where needed, and either leave the chip mound to settle, spread it as mulch, or haul it and backfill so the spot is seed-ready.
Standard depth suits grass and garden beds. Planning a fence post, a patio, a driveway, or a replacement tree in the same hole? Tell us when we quote, and we grind deeper to match what is going there.
Tight access is our normal
Humboldt lots were not designed around tree equipment. Our grinding setup is chosen to fit through standard gates, down narrow side yards, and onto the sloped and soft soil that turns bigger rigs away. Send a photo of the access with your quote request and we will confirm the fit.
Utilities come first
Grinding happens below the surface, so buried lines matter. Utility locating is part of the process before teeth touch soil, and we route around irrigation and known private lines rather than through them.
What stump grinding costs
Stump grinding is priced by the stump: its diameter, its species and condition (old rotten stumps grind fast, green redwood grinds slow), the depth you need, access for the machine, and how many stumps we can do in one visit. Multiple stumps on the same trip cost meaningfully less per stump than one-off visits, so if you have three, quote all three.
You do not need to have used us for the removal. A steady share of our grinding jobs are stumps another company, or another decade, left behind. Quotes are free, and most residential stumps are finished in a single visit.
Before grinding day
Two things make a grinding appointment go smoothly. First, we need to know what is buried near the stump: irrigation lines, low-voltage lighting wire, a septic lateral, anything you know about. Utility marking handles the big services, but the backyard surprises are the ones worth mentioning. Second, gates: our tight-access grinder fits through standard side-yard gates, and knowing the width ahead of time means we bring the right machine the first trip.
What happens to the grindings
Grinding a stump produces a surprising mound of wood chips mixed with soil. You have three options: leave the mound to settle and use it as mulch, have us rake it into the hole and tamp it so the spot is level and plantable, or have us haul every chip away and backfill with topsoil. Most homeowners split the difference: backfill the hole, keep a little mulch for the beds, haul the rest.
One honest note: grindings from the stump itself make fine path mulch but poor planting soil, because the decomposing wood ties up nitrogen for a season or two. If you want to replant in the same spot, tell us and we will grind deeper and backfill with real soil.
