Stump Grinding Below Grade in Gainesville, FL

When a tree comes down, the stump stays unless you ask for it to go. Most people do. A stump in the lawn is something to mow around, trip over, and watch sprout or rot for years. Grinding it while the crew is already on site is the simplest way to finish the job, and it is quoted as a separate line on every Gainesville tree removal estimate so you can decide.

We also grind old stumps from trees that someone else took down. Those jobs are just as common, especially when a homeowner is ready to redo a lawn, add a patio or put in a fence and finds an old stump in the way.

A stump grinder is a machine with a heavy spinning wheel set with carbide teeth. The operator sweeps the wheel back and forth across the stump, chewing it into a mix of wood chips and soil a layer at a time, working down below the surface. Nothing is pulled out of the ground. The roots below and beyond the grinding area stay in place and break down slowly over the years.

1. Check for utilities. Before any grinding, buried lines are located (more on that below).
2. Clear the area. Rocks, edging and debris around the stump are removed so they do not get thrown or damage the teeth.
3. Grind the stump. The stump is ground below grade, deep enough to fill and sod over. Large surface roots can be ground out too if you ask.
4. Deal with the grindings. You choose: chips back in the hole, chips spread as mulch, or chips loaded on our truck.

Grinding goes below the surface, so it counts as digging under Florida's underground facility law. Sunshine 811 needs a request two whole business days ahead of the work; the day you file, weekends and holidays do not count toward that wait. The utilities then mark their lines with paint or flags, and those marks are good for 30 calendar days. If grinding has not happened in that window, a new request is needed.

Utility marks only cover lines the utility owns. Private lines, such as irrigation pipes, low-voltage lighting, a line to a detached garage or a well pump, are not marked by 811. Point those out to us. A stump near a septic tank or drain field also needs care, because a grinder can damage pipes just below the surface.

The trickiest stumps are the ones right against something hard. A tree planted beside a driveway, a patio slab or a pool deck usually has roots running under the concrete, and its stump often touches the edge. A grinder wheel cannot work under concrete, and grinding hard against an edge can chip it. In those spots we grind the stump down as far as the edge allows, then cut back the rest by hand where needed.

Roots already under a slab stay there. They will slowly decay, and in some cases the soil above them settles enough to leave a small void. That is not something grinding causes or prevents, but it is worth knowing if you have a stump next to a walkway that already lifted. Stumps beside foundations get the same careful treatment, with the wheel kept off the wall and the grindings pulled away from the house afterward.

Stump grinding is priced mainly by the diameter of the stump, with adjustments for roots and access. Here is what most single stumps cost.

Oak stumps often run to the higher end because they flare wide at the base and send thick roots out near the surface. Pine stumps usually grind faster. Palm stumps are fibrous rather than woody and grind differently, but most fall in the small-to-medium range.

One stump makes a surprising amount of grindings, often a mound much bigger than the stump itself, because the chips are fluffy and mixed with soil. You have a few options:

• Backfill the hole. Grindings can go back in the hole, but they settle as they break down. Most people top the hole with soil before sodding.
• Use as mulch. Raked into beds away from the house, grindings make a coarse mulch. Keep them away from the foundation.
• Haul them away. We can load and remove them. The City of Gainesville's curbside yard waste service does not accept stumps, and large piles of grindings are not curbside material either.

Palm stumps and Ganoderma

If a palm was removed because of Ganoderma butt rot, UF/IFAS recommends removing as much of the stump and roots as possible and not planting another palm there. For those stumps, we grind as deep as practical and haul the grindings away rather than leaving them in the yard. More on palms is on the palm tree removal page.

Grinding takes the stump down below grade and leaves roots in the soil. Full removal digs or pulls the whole stump and its main roots out of the ground, leaving a large hole and disturbed soil. Grinding is cheaper, faster and kinder to the lawn, and it is enough for sod, most planting and most landscaping. Full removal is mainly for construction, like a footing or slab, where all the wood has to go. Our article stump grinding vs stump removal explains the trade-offs.

Access is the main local variable. Older city lots like those in Florida Park often have narrow side gates and fenced backyards, so a compact grinder that fits through a standard gate is the tool. On larger lots around Millhopper and out toward the rural edges of the county, a larger machine can reach the stump directly. Tell us your gate width when you ask for a price, and mention any steps, slopes or soft ground between the gate and the stump, since a loaded grinder is heavy and needs firm footing. If a lot has many stumps, as after a big clearing job, lot clearing pricing may make more sense than counting stumps.
