Stump Grinding And Removal Are Two Different Jobs
Grinding is a machine with a toothed wheel that cuts the stump into chips, working down and outward. It leaves a hole full of chip and sawdust and it disturbs very little around it.
Digging a stump out with an excavator takes the root plate as well, which sounds better and usually is not. It leaves a crater, it wrecks the surrounding lawn, and on the sandy ground around Paris it takes far more soil with it than people expect. It also costs considerably more.
Stump grinding and removal by machine is the right answer for nearly every garden stump. Excavation is for where the ground has to be built on.
How Deep Stump Grinding Needs To Go
That depends entirely on what is going there afterwards, and it should be in the quote.
For lawn, 150 to 200mm below grade is normally enough. Grass roots do not go far and the chip can be topped with soil and seeded.
For a flower bed you want more, because you need actual soil depth to plant into.
For paving, a shed base or a fence line, more again, and the surface roots usually have to be chased out too — which is a separate cost and worth agreeing before anybody starts.
If nothing is going there and you just want the trip hazard gone, less is fine and it is cheaper.
Stump Grinding And Removal Leaves You The Chip
Stump grinding and removal produces a surprising volume of chip — considerably more than the stump appeared to be, because it is all air now.
By default we backfill the hole with it and rake it level. It will settle over the first year and usually needs topping up, which is normal rather than a fault.
If you want soil instead, the chip has to be barrowed out and soil brought in, and that is a separate line on the quote. Do not plant directly into fresh chip. It ties up nitrogen as it breaks down, and things planted into it sulk for a season or two.
What We Need To Know Before A Stump Grinding And Removal Visit
Where the services are. Gas, water, hydro, telecoms and irrigation all get cut by stump grinders, and the machine does not know they are there. If anything has been run through that part of the garden, tell us.
What the access is. Grinders come in sizes. The small ones walk through a standard garden gate on tracks; the big ones do not, and they clear a large stump in a fraction of the time. If the stump is in a back garden, the gate width decides which machine turns up and how long stump grinding takes.
Whether there is stone, wire or fencing embedded in or near the stump. Old fence line stumps often have wire grown through them, and hitting it ruins a set of teeth and stops the stump grinding and removal dead.
