After a tree has been removed, you are usually left with a stump protruding from the ground. While it might seem harmless, stumps can attract termites, create tripping hazards, prevent replanting, and make mowing difficult. Stump grinding is the most common and efficient method for dealing with them.
What Is Stump Grinding?
Stump grinding uses a specialised machine with a rotating cutting wheel that chips away the stump and surface roots, typically grinding to a depth of 150 to 300 millimetres below ground level. The result is a hole filled with wood chips and mulch where the stump used to be. Unlike full stump removal, grinding does not extract the entire root system but eliminates the visible stump and the major root crown.
How the Process Works
Step-by-Step
- The area around the stump is cleared of rocks, debris, and any obstructions
- The grinder is positioned over the stump and the cutting wheel is engaged
- The operator systematically moves the wheel back and forth, grinding the stump from one side to the other
- Grinding continues to the desired depth below ground level
- The resulting wood chips are used to fill the hole or removed from site
- The area is raked level and left ready for turf, garden, or construction
How Much Does Stump Grinding Cost?
The cost of stump grinding depends on the stump’s diameter, the wood hardness, access for the grinding machine, and the number of stumps being ground. As a general guide, expect to pay $100 to $500 per stump for most residential jobs. Multiple stumps on the same visit are usually discounted, and many arborists offer stump grinding at a reduced rate when combined with tree removal.
When to Choose Grinding Over Full Removal
Stump grinding is suitable for most situations where you simply want the stump gone and do not need the root system extracted. It is faster, cheaper, and less disruptive than full stump removal. However, if you are planning construction, installing a pool, or need to completely eliminate the root system, full removal may be necessary.

What Happens After Grinding?
After grinding, the wood chips left behind will decompose over time, causing the ground to settle slightly. You can top up with soil and lay turf, plant a new tree, or use the area for garden beds. Some species, particularly eucalyptus, may produce regrowth shoots from remaining roots. Applying a herbicide to the ground wood chips can prevent this.
