Most homeowners expect a complicated answer to this. It is actually pretty simple. The right choice comes down to one question: what are you planning to put in that spot after the stump is gone?
Stump grinding uses a rotating cutting wheel to chip the stump down below grade. Standard residential grinding takes the stump 6 to 12 inches below the existing soil surface. The grinding head makes overlapping passes until the stump is gone, and what remains is a mound of wood chip debris in the hole where the stump used to be.
The roots stay underground. This is the part that concerns some homeowners, but in practice it is rarely a problem. Tree roots that are no longer connected to a living tree cannot grow. They decay over time, cottonwood in 3 to 5 years, hardwoods in 8 to 12. The decay is slow and mostly happens without you noticing, except for occasional minor settling above the old root zone.
Grinding is fast. A typical job takes 1 to 2 hours. It is significantly less expensive than removal. For most residential situations, it is the right call.
Stump removal is a different operation. Instead of chipping the stump in place, the goal is to excavate the entire root ball out of the ground. That typically means cutting the lateral roots outward from the stump, then leveraging or lifting the root ball free. Larger jobs require an excavator or skid steer. Smaller stumps can sometimes be pulled with a winch.
The result is a clean hole. No organic material underground, no roots decaying over the next decade, no settling from root decomposition. The hole gets backfilled with clean soil.
The tradeoff: it costs significantly more. The equipment is heavier, the labor is harder, the job takes longer. A stump that costs a few hundred dollars to grind might cost several times that to fully extract depending on root system size and soil conditions. And the work is more disruptive to the surrounding yard.
For the vast majority of residential jobs in Spokane, grinding is enough. If you are putting lawn, a garden bed, mulch, or a flower planting over the spot, grinding handles it. The roots underground will decay. The ground will be stable. You can plant over it.
If you want to plant a new tree in the general area but not in the exact same hole, grinding works. Plant the new tree a few feet away from the old root zone and there is no conflict.
If you just want the visible stump gone because it looks bad, grinding does that cleanly. The wood chip fill rakes level with your yard, and within a season or two you can barely tell a tree was there.
Grinding also makes sense when the stump is in a tight spot where excavation equipment cannot access. Many Spokane backyards have limited gate widths or fenced areas where a large excavator simply cannot fit. A stump grinder can work in spaces where full removal is not practical.
There are specific situations where grinding is not enough and you should invest in full removal.
If you want to plant a new tree in the same spot, that is the most common reason to choose removal over grinding. The old root system underground will compete with new roots, and the decaying organic material creates an unstable, nitrogen-imbalanced zone for new growth. Pull the old root ball and you start clean.
Construction is another clear case. If you are pouring a concrete driveway, patio, or foundation pad over the spot where the stump was, organic material underground will cause uneven settling as it decays. That settling shows up as cracked concrete over time. Removal before any concrete work is the right approach.
Installing an irrigation system through the root zone is another situation where removal can prevent problems. Decaying roots shift over time, and in-ground irrigation lines running through that zone can get pushed out of alignment or crushed as roots compress during decay.
If your project contractor specifically requires a clean subsurface, take them at their word. Some landscaping projects, particularly large hardscape installations, specify stump removal for good reason.
Outside of these situations, grinding almost always does the job. Most homeowners who ask about removal end up going with grinding once they understand what each option actually delivers.

This is the question that comes up most often. Homeowners want to know if the decaying roots underground will cause problems.
For most yard applications, they do not. The roots compact slowly as they decay. You might notice a slight depression in the lawn above the old root zone in the first year or two, which you can fix by adding topsoil and reseeding. Beyond that, decay is silent and slow and causes no structural issues for a lawn or garden.
Cottonwood roots decay faster than hardwoods. A cottonwood stump ground in spring might leave a noticeable depression within 18 months. An oak or locust root system can be present for a decade before you notice much change above ground.
If regrowth from lateral roots is a concern, cottonwood and black locust in particular can send up sprouts from roots that were not ground. If that happens, a follow-up treatment handles it. It is not common, but it does occur with certain species. See our pricing guide for information on what affects the overall scope and cost of stump work.

Grinding is the right answer for most homeowners. It is faster, less expensive, and causes less disruption to the surrounding yard. The only situations that clearly require full removal are new tree planting in the same hole, concrete or foundation work over the spot, and certain construction projects.
Minor settling above the old root zone is possible over the first year or two as the roots decay. You can fix it by adding topsoil and reseeding. It is not the same as a structural problem, just a cosmetic one that one correction pass handles.
Yes. Add topsoil to fill the hole and remove the chip debris first. The remaining roots underground will not interfere with a surface garden bed. They decay without disturbing what is planted above.
A typical residential stump removal takes 2 to 4 hours. Large stumps with extensive root systems can take a full day. Grinding the same stump would take a fraction of that time.
Full stump removal is the only option for a completely clean subsurface. Grinding leaves the root system in place to decay over years. If your project requires a clear subsurface, request removal and describe the project to your provider so they can account for the full root system in the quote.
