One of the most common questions we get from homeowners is "how deep does a stump grinder go?" The answer depends on your plans for the area and the type of equipment being used. Here's everything you need to know about stump grinding depth.
STANDARD STUMP GRINDING DEPTH: 6-8 INCHES
Most professional stump grinding services grind stumps to a depth of 6-8 inches below ground level. This is the industry standard and is sufficient for most residential applications, including:
- Planting grass seed over the area
- Installing flower beds or landscaping
- General yard use and lawn maintenance
- Preventing visible regrowth
At 6-8 inches deep, the stump is far enough below the surface that you can add topsoil, plant grass, and mow over the area without any issues. The remaining roots will naturally decompose over 5-10 years.
WHEN DO YOU NEED DEEPER GRINDING?
Some situations require grinding deeper than the standard 6-8 inches:
Building or Construction (12-18 inches)
If you're planning to build a structure, pour concrete, or install a patio over the stump location, you'll need deeper grinding. Most contractors recommend 12-18 inches for construction projects to ensure a stable foundation.
Replanting a Tree (10-12 inches)
If you want to plant a new tree in the same spot, deeper grinding (10-12 inches) helps give the new tree's roots room to establish without competing with the old root system.
Underground Utilities or Irrigation
Installing sprinkler systems, drainage, or underground utilities may require deeper grinding to allow for proper pipe placement.
Grinding Depth Guide
| Use Case | Recommended Depth |
|---|---|
| Lawn/Grass | 6-8 inches |
| Flower Beds/Landscaping | 6-8 inches |
| Planting New Tree | 10-12 inches |
| Patio/Walkway | 10-12 inches |
| Building/Foundation | 12-18 inches |
WHAT ABOUT THE ROOTS?
A common misconception is that stump grinding removes all the roots. In reality, stump grinding only removes the main stump and the root flare (where the trunk meets the roots). The lateral roots extending outward remain in the ground.
Is this a problem? Usually not. Here's why:
- Roots naturally decompose over 5-10 years
- They won't regrow without the main stump
- Decomposing roots actually enrich the soil
- Surface roots can be ground down if visible
The only exception is certain aggressive tree species (like willows, poplars, or some maples) that can send up suckers from roots. For these species, treating the stump with herbicide or grinding deeper may be recommended.
HOW DEEP CAN STUMP GRINDERS GO?
The maximum grinding depth depends on the equipment:
- Rental/homeowner grinders: 4-8 inches maximum
- Professional mid-size grinders: 12-16 inches
- Large commercial grinders: 18-24+ inches
This is one reason professional stump grinding services can achieve better results than DIY rental equipment. Our commercial-grade grinders can reach deeper when your project requires it.
DOES DEEPER GRINDING COST MORE?
Yes, grinding deeper than the standard 6-8 inches typically costs more because it requires more time and puts more wear on the equipment. Most stump grinding companies charge an additional fee for deep grinding. At Nelson Stump & Land Clearing, we'll discuss your plans for the area during the estimate so we can recommend and price the appropriate depth.

After grinding, you're left with a hole filled with wood chips mixed with soil. The hole is typically 6-8 inches deep (or deeper if requested) and extends slightly beyond the original stump diameter. You have a few options:
- Leave the chips: They'll settle and decompose over time
- Use as mulch: Spread the chips in garden beds
- Fill with topsoil: Add soil on top of chips for grass planting
- Haul away: We can remove the chips for an additional fee
