Stump grinding is priced on the diameter of the stump and how easily a machine reaches it. Around Tewkesbury there is a third factor that comes up more than elsewhere: whether the ground can take the machine at all.
Ground conditions
A stump grinder is a heavy machine, and on saturated low-lying ground it either cannot get to the stump or leaves ruts getting there. Both change the job.
It also matters for anything you are keeping. Machinery on wet ground compacts soil considerably more than on dry, and compaction over a root zone damages trees slowly and invisibly. Boards under the route are worth asking for where anything heavy has to cross near a tree that is staying.
What else drives the price
| Factor | Effect |
|---|---|
| Stump diameter | The main driver — measured across the cut face |
| Access | Which machine can be used, and how far material travels |
| Ground conditions | Whether the machine can get there at all |
| Depth required | Deeper for paving or a base than for lawn |
| Stones and rubble | Slow the machine and wear the teeth |
| Number of stumps | Several in one visit is far cheaper than several visits |
| Chip disposal | Leaving it on site costs less than carting it away |
The consequence people find counter-intuitive: a wide, low stump in a soft corner can cost more than a taller, narrower one on firm ground beside a drive. Diameter and access, not the height of the tree that was there.
Specify the depth by what is going on top
| Going on top | Depth needed |
|---|---|
| Lawn or turf | About 6in below ground level |
| Borders and planting | Deeper — and dig the chip out |
| Paving or patio | Below the full build-up depth |
| Decking | Below the frame and any footings |
| Shed base | Deepest — plus the main root plate |
| Fence line | Below post depth, along the whole run |
Telling the contractor what is going in that spot is the most useful instruction you can give. A stump ground for lawn and then paved over is a settlement problem waiting eighteen months to appear.
What grinding does and does not do
It takes the stump down below ground level and turns it into chip, dealing with the stump and the main roots immediately around it. It does not remove the wider root system — those roots stay and break down over the following years.
For lawn, paving or a fence line that is entirely fine. For planting a new tree in exactly the same spot, it matters — dig the grindings out and backfill with topsoil, because decomposing wood chip pulls nitrogen from the surrounding soil.
The settlement issue
Grinding leaves a hole filled with chip mixed into soil, and that chip breaks down over the following years. As it does, the ground sinks.
Under lawn that is a top-up once in the first year. Under paving it is a dip appearing eighteen months after the patio was laid, and fixing it means lifting slabs. So where anything solid is going over a ground stump, the grindings should be dug out and backfilled with compacted subbase.
When the stump can stay
- Nothing is planned for that spot.
- It is in a border or behind a shed, out of the way.
- It is low and flat and will rot down on its own.
- Access or ground conditions make grinding disproportionately expensive.
- The tree was healthy when felled, so there is no disease concern.
That last one is the qualifier. A stump from a tree that was in decline can be a food base for honey fungus, which spreads through soil and affects a wide range of garden plants — worth removing even where the spot is not needed.
Decide before the tree comes down
One check on a protected tree
A Tree Preservation Order can extend to the stump as well as the standing tree, and consent to fell is not automatically consent to grind out what is left. Where the tree was protected — by a TPO, or by standing in Tewkesbury's conservation area — confirm with Tewkesbury Borough Council that the stump work sits inside the consent or notice you hold.
