Stump Grinding vs Stump Removal: What's the Difference?

The short answer

Stump grinding shaves the stump down below ground level using a specialised cutting machine — the visible stump is gone, but the root system stays in the soil and decays naturally over a few years. Stump removal pulls the entire stump and root ball out of the ground — more thorough, but it leaves a big hole and costs significantly more. For 9 out of 10 garden situations, grinding is the right answer.

What stump grinding actually involves

A stump grinder is essentially a powered cutting wheel that chews through wood and soil. We position it over the stump and gradually work the wheel down, taking the stump out in chips. Most domestic stumps come out about 15–30cm below ground level — enough that you can re-turf, replant, or pave over the area without seeing anything.

The chips and shavings can either be left on site (they make decent mulch once they break down) or bagged up and taken away. The roots stay where they are. They'll decay over 3–7 years depending on the species — conifers go quickly, oaks take their time.

What stump removal involves

Removal means digging the whole thing out — stump, root ball, and major lateral roots. For small ornamental trees this can be done by hand with a mattock and a saw. For anything bigger, you're looking at a mini-excavator and several hours of work.

What you're left with afterwards is a hole, often a substantial one, that needs filling with soil before you can do anything else with the ground. On a large mature tree, the hole can be the size of a car.

Cost comparison

Stump grinding: Typically £80–£250 per stump depending on size and access. Often added to a tree removal job at a discount.

Stump removal: £300–£800+ per stump. Can be much more if a digger needs to be brought in and there's hard access.

Grinding wins on price for most domestic jobs.

When to choose grinding

— You want to lay turf, paving, or decking over the area.

— You want to replant in the same spot with something smaller (ornamental shrubs are fine over decaying roots).

— The stump is just unsightly and you want it gone.

— Budget is a factor.

When to choose removal

— You're planting a replacement tree in exactly the same spot — the new tree's roots won't grow well into the decaying old root system, so removal gives the new one a clean start.

— The tree had a serious fungal infection (honey fungus, for example) that you don't want to leave in the soil to spread to other trees.

— Building work is planned and the foundations would otherwise be over the root system.

— The stump is causing structural issues with paths or walls and you need the lateral roots out too.

What about chemicals?

Stump killers (chemicals you paint onto a fresh cut to kill the root system) are widely sold and widely useless. They slow regrowth on species that would resprout anyway — willows, leylandii, sycamores — but they don't make the stump disappear. You'll still need to grind or remove it eventually.

One use case: if you can't afford to grind or remove right now but you want to stop the stump putting up new shoots, a chemical treatment buys you a couple of years.

Want it done?

Most of the time, when we remove a tree, the customer asks us to grind the stump at the same time. It's cheaper as a combined job, and you walk away with a clean garden. Give us a call and we'll quote both options for your specific situation.
