Stump Grinding in St. Augustine, FL

A stump grinder is a wheel of carbide teeth that sweeps side to side, taking off an inch or two at a pass. We grind the visible stump down and then keep going, chasing the root flare out in every direction until the wood is below the depth of anything you plan to put there.

Standard depth is six to twelve inches below grade. If you are planting a new tree in the same hole, we go deeper and chase roots wider, because young roots do not compete well with a mat of old wood. If you are just re-sodding, six to eight inches is plenty. Tell us what the spot is for and we will grind to suit it.

Before the machine touches anything we call in a utility locate and check for irrigation lines, low-voltage lighting, septic, and invisible fence wire. Sandy Northeast Florida soil is easy digging, which is exactly why so much of it has shallow lines run through it.

Grinding produces a surprising volume of chips — roughly two to three times the visible stump. You have three options, and the choice is yours at quote time.

Full removal means excavating the entire root ball with a machine. It is far more expensive, it wrecks the surrounding lawn and any nearby irrigation, and it leaves a hole that must be backfilled and compacted. There are cases where it is genuinely necessary — a footing going in exactly where the stump sits, or a pool dig — but for a homeowner who wants grass or a garden bed, grinding does everything you need for a fraction of the cost and the disturbance.

The one thing grinding does not do is remove every lateral root in your yard. Those roots stay in the ground and decompose over several years. That is fine under sod and mulch. It matters if you are pouring a structural slab, in which case tell us up front and we will talk through excavation instead.

Surface root grinding is its own service and one we do often in older St. Augustine neighborhoods where mature oaks have lifted sidewalks and sod. We grind the offending roots below grade, but there is a limit: cut too many roots too close to the trunk and you destabilize a tree you were trying to keep. Robert will show you what can safely come out and what needs to be worked around with a raised bed or a re-routed walkway instead.

Palm stumps grind differently than hardwood. Palm trunks are fibrous rather than woody, so they cut fast, but sabal palms in particular have a dense root initiation zone that can extend a few feet across. We grind wide enough to clear it.

Old, weathered stumps often have sand and grit driven into the wood by years of rain, which dulls grinder teeth fast. That is a cost factor, not a problem — it just means an old stump can price out slightly higher than a fresh one of the same diameter.
