Once a tree has been removed, the job may look finished from above ground. Yet the stump and much of the root system are still sitting below the surface.
That leaves property owners with a decision: leave the stump where it is, grind it below ground level, or arrange more extensive removal for future building, paving or planting.
For many Northern Beaches properties, stump grinding after tree removal is the practical next step. It can clear usable space, reduce a trip hazard and prepare the area for turf, garden work or site access. The right approach depends on the stump size, machine access, underground services and what you want to do with the area next.
This guide explains what to do with a tree stump once the tree itself is gone.
Key Takeaways
- Tree removal does not automatically mean stump removal. Grinding may need to be added to the scope separately.
- Stump grinding after tree removal can make the area easier to use for turf, planting, paving preparation or general access.
- Grinding depth should suit what comes next. A shallow garden repair has different requirements from site preparation for construction.
- Stump grinding access matters. Gates, stairs, slopes, retaining walls, fences and nearby structures can affect the equipment used.
- Old roots usually remain underground after grinding. They break down over time, and some tree species may send up shoots from remaining roots.
Why Stumps Are Left Behind
Tree removal and stump grinding are separate jobs
Professional tree removal focuses on safely taking down the canopy and trunk. Once the tree has been cut close to ground level, a solid stump and much of the root system remain.
Grinding requires different equipment and a separate work area. This means stump work may need to be included as a separate part of the original scope.
Before approving a removal quote, check whether the stump will remain and whether grinding is included.
What happens if you leave the stump?
A stump can remain in the ground and slowly decay. That may suit an area that is out of the way and has no planned future use.
Problems can arise when the stump sits beside a lawn, pathway, driveway, shared area or future project space.
Common issues include:
- reduced usable garden or lawn space
- a raised obstacle around walking or mowing areas
- interference with future paving or planting
- new shoots from the stump or remaining roots in some species
- gradual soil movement as the wood and roots decay
- an unfinished appearance after the main tree has been removed
Colorado State University Extension explains that some tree species can produce suckers from remaining roots after the main tree has been removed.
For property owners who want the site cleared and easier to use, stump grinding is often the next service to assess.
Should you keep the stump or grind it?
| Option | May suit | Main points to check |
| Leave the stump | Low-use garden areas with no immediate plans | Trip points, mowing access, appearance and possible shoots |
| Grind the stump | Lawns, gardens, access areas and sites needing a cleaner finish | Machine access, depth, underground services and debris |
| Excavate stump and roots | Some construction or major site works | Larger excavation area, soil disturbance and machinery access |
Grinding removes the main stump without excavating the full root system. Roots farther from the trunk commonly remain underground.
When Grinding Makes Sense
You want usable space back
A stump can occupy more room than its visible diameter suggests. Large buttress roots may extend into lawns, paths and garden beds.
Stump grinding after tree removal can help when you want to:
- restore lawn
- open a walking or mowing route
- clear a shared strata space
- prepare part of a garden for planting
- improve access for later works
- create a cleaner finish after removal
For homeowners, this often comes down to making the yard practical again. For strata and commercial properties, clearing a stump may improve access through common areas and make future maintenance easier.
The stump is blocking an access area
A stump does not need to be tall to cause problems. A low stump can interfere with driveways, side passages, lawn maintenance and pedestrian areas.
This is particularly relevant on Northern Beaches properties where access may already be restricted by narrow side paths, retaining walls, sloping blocks or established landscaping.
Grinding the stump can clear the main obstruction without digging out the entire root system.
You have building or landscaping work planned
Builders and property owners may need to remove stump after tree removal before excavation, fencing, landscaping or paving starts.
The required scope depends on what will happen next.
For example:
- Turf may need enough depth for soil preparation.
- Garden planting may need a clearer growing area.
- Paving may need additional excavation and base preparation.
- Footings or drainage works may require roots to be removed beyond standard grinding.
Tell the arborist about the planned use of the area when requesting a quote. This gives the crew a better basis for assessing grinding depth and site preparation.
Access and Grinding Depth
Stump grinding access affects the equipment used
A stump grinder needs a suitable route from the property entrance to the work area.
Stump grinding access can be affected by:
- narrow gates
- stairs
- retaining walls
- steep or uneven ground
- swimming pools
- fences
- garden beds
- buildings
- paved areas
- shared pedestrian routes
On tight Northern Beaches sites, access can determine which machine can be used and how the work area needs to be set up.
Photos can help with an initial assessment. Take one clear image of the stump and wider photos showing the route from the street or driveway to the work area.
How deep does stump grinding go?
There is no single grinding depth for every property.
Iowa State University Extension states that professional stump grinding commonly removes material around 8–12 inches below the surface, or roughly 20–30 cm.
The actual depth needed depends on factors such as:
| Factor | Why it matters |
| Future turf | Enough space may be needed for soil and grass establishment |
| New garden beds | Remaining woody material can limit planting space |
| Paving | The area may need further excavation and base preparation |
| Construction | Deeper roots may affect future works |
| Underground services | Grinding depth may need to be restricted |
| Stump size | Larger stumps can involve wider root flares |
| Ground conditions | Slopes, rock and surrounding surfaces affect access |
The most useful question is not simply how deep the machine can grind. The better question is how much stump needs to be removed for the next use of the site.
Underground services need attention
Stump grinding works below ground level, where electricity, gas, telecommunications, drainage and water services may be present.
SafeWork NSW’s Tree Work Code of Practice includes precautions for underground services during stump grinding, including checks when penetration exceeds 200 mm below the surface or where nearby services may be present.
A professional assessment should account for known or suspected services before deep grinding takes place.
DIY work can carry significant risk where service locations, buried materials or machine operation are uncertain.
Replanting or Turf Recovery
Can you lay turf after stump grinding?
Yes. The area normally needs preparation first.
Grinding creates a mix of wood chips, sawdust, soil and small root fragments. Large amounts of woody material can make the area less suitable for immediate turf establishment.
Iowa State University Extension recommends removing excess wood debris and sawdust before establishing grass. Fresh soil can then be added where required.
A typical recovery process may include:
- Remove excess stump grindings.
- Check the remaining hole and soil level.
- Add suitable soil.
- Allow for some settling.
- Prepare the surface.
- Install turf or sow grass.
- Top up low areas later if settlement occurs.
Roots deeper underground continue to decay after the stump has been ground. Minor settlement can occur as this material breaks down.
Can you plant another tree in the same location?
It may be possible, but the exact position of the former stump is not always the easiest place for a replacement.
Old roots and remaining woody material can limit the new planting hole. Soil mixed heavily with stump grindings may need preparation before planting.
When planning tree planting, consider:
- available rooting space
- mature tree size
- nearby buildings
- fences and paving
- drainage
- underground services
- sunlight
- wind exposure
- access for future maintenance
Iowa State University Extension suggests placing a replacement tree away from the former stump where site space permits.
Choosing the right position from the start can reduce future conflicts with structures, access routes and neighbouring properties.
What if paving or construction is planned?
Tell the arborist before the stump is ground.
Standard grinding may clear the visible stump and main root flare yet leave deeper roots underground. This may be enough for lawn restoration but not for every construction project.
A builder may require additional removal where:
- footings will cross the root zone
- drainage needs to run through the area
- excavation is planned
- paving requires deeper preparation
- machinery needs unrestricted access
This information should be included when requesting the grinding quote.
Preparing for a Quote
A clear quote starts with useful site information.
Before contacting an arborist, gather:
- your suburb
- the number of stumps
- photos of each stump
- approximate stump diameter
- photos showing machine access
- the width of narrow gates or passages
- details of stairs or slopes
- nearby walls, fences, pools or structures
- known underground services
- your plans for the area after grinding
- whether you want excess grindings removed
What affects stump grinding cost?
Stump size matters, but it is not the only factor.
Pricing may be affected by:
- stump diameter
- number of stumps
- root flare size
- machine access
- grinding depth
- slope or ground conditions
- proximity to structures
- underground service risks
- site clean-up requirements
- disposal of grindings
Sending clear photographs can help the arborist assess the job before a site visit or formal quote.

Stump Grinding FAQs
Is stump grinding included with every tree removal?
No. The stump may be left behind unless grinding forms part of the agreed scope. If you want both services completed, ask whether tree removal and grinding are included in the quote.
Will a tree stump die after the tree is removed?
Many stumps eventually die and decay. Some species can produce shoots from the stump or remaining roots. How quickly this happens depends on the species and site conditions.
Does stump grinding remove all tree roots?
No. Stump grinding removes the stump and accessible woody material around it. Roots extending farther underground commonly remain and decay naturally over time.
How deep should a stump be ground?
The required depth depends on what you want to do with the site. Lawn recovery, planting, paving and construction can each require a different scope. Underground services can restrict grinding depth.
Can a stump grinder reach a backyard with narrow access?
It depends on the machine and access route. Send photographs of gates, side paths, stairs and slopes when requesting a quote. Include the width of the narrowest point where possible.
Can I put turf directly over stump grindings?
Removing excess wood chips and sawdust before adding soil usually creates a better base for turf. The area may need extra soil as the remaining underground material settles.
Can I plant a new tree where the old stump was?
It can be possible, but a nearby position may provide better soil and fewer old roots. Before arranging tree planting, consider the new tree’s mature size, available root space and nearby structures.
Is DIY stump grinding safe?
Stump grinders use fast-moving cutting equipment and work below the soil surface. Hidden services, stones, metal and other buried materials can create serious hazards. A qualified operator can assess these risks and set up an appropriate work zone.
What information should I send for a stump-grinding quote?
Send your suburb, stump photos, approximate size, access photos, nearby structures and your planned use for the area. These details help the arborist assess equipment access, grinding depth and clean-up requirements.
