Stump Grinding

What stump grinding is, why we recommend removing stumps, benefits, and risks of leaving stumps in place. References to ISA, ANSI, OSHA, and Florida resources included.

What is stump grinding?

Stump grinding is the mechanical removal of the visible portion of a tree stump using a rotating cutting wheel mounted on a grinder. Grinding reduces the stump to wood chips and a shallow root collar grind that clears space for replanting, turf, or landscaping.

Why we recommend removing stumps

• Safety and usability: Stumps are trip hazards and impede mowing, landscaping, and site use.
• Pest & disease reduction: Old stumps can attract termites, carpenter ants, wood-boring beetles, and provide substrate for pathogenic fungi.
• Regrowth control: Many species resprout from the stump; grinding reduces vigorous suckering and unwanted regrowth.
• Aesthetics & site preparation: Grinding clears planting areas and improves curb appeal without large excavation.
• Reduced long-term liability: Eliminating hidden roots and trip hazards lowers future maintenance and safety risk.

Negative effects of leaving stumps in place

• Structural pests: Stumps can attract termites and other wood-feeding insects that may migrate to nearby structures or trees.
• Fungal colonization: Decay fungi break down stumps and may increase inoculum levels for root diseases in the landscape.
• Regrowth and suckering: Species that resprout may create dense suckering, requiring ongoing control efforts.
• Landscaping limits: Stumps restrict planting options and can complicate grading, irrigation, and construction.

Benefits of stump grinding

• Quick site restoration with minimal disturbance compared with full excavation.
• Woodchips may be reused as mulch where appropriate (check species and pest/disease concerns).
• Reduces pest habitat and fungal inoculum near desirable plants and structures.
• Fewer safety hazards and easier grounds maintenance.

Safety, equipment & regulatory guidance

Stump grinding uses powered equipment and rotating cutting teeth — operators should follow equipment manufacturer's instructions and worker-safety standards. The resources below provide industry best practices and legal/safety guidance.

• International Society of Arboriculture (ISA) — arboricultural guidance and best practices.
• ANSI A300 standards — industry performance standards (see relevant parts for removal and site work).
• OSHA — safety requirements relevant to powered equipment, PPE, and jobsite controls.
• Florida Department of Agriculture & Consumer Services (FDACS) — state pest and disease programs and guidance affecting tree care.
• Florida Statutes (Online Sunshine) — consult local and state statutes and municipal codes for permitting, protected-tree rules, or right-of-way requirements.

Use licensed, insured, and experienced professionals for large stumps, work near utilities/structures, or where permitting is required.

When to hire a professional

• Large-diameter stumps where grinding close to structures, sidewalks, or utilities is required.
• When pests or fungal decay are suspected and you need diagnosis or containment.
• If local permits or municipal rules apply to tree and stump removal.
• When woodchip disposal, regrading, or replanting is part of the job scope.
