Tree Removal
Whole trees taken down, from a backyard camphor laurel to a spotted gum leaning over a Merewether roofline.

Grind depth is a decision, not a fixed number, and it should be made against what is going on top.
| What is going over the stump | Typical grind depth | Why |
|---|---|---|
| Lawn or turf | 200–250 mm | Enough soil above the grindings for roots and mowing |
| Garden bed or shrub planting | 300–400 mm | Room to backfill with real soil, not carbon |
| Pavers or a path on a sand bed | 300 mm | Keeps the base stable as the remaining wood decays |
| Slab, footing or pool | Grinding is not enough | The root plate needs excavating, not grinding |
| Back paddock, nothing planned | 100–150 mm | Removes the trip hazard and the mower risk, no more |
The practical limit is what is beside the stump. Services, rock, retaining walls and neighbouring footings all stop a grinder before the operator wants to stop.
What grinding leaves in the ground
The lateral roots. A mature tree's roots run out to roughly the width of its canopy and sometimes further, mostly in the top half-metre of soil. Grinding takes the stump and the crown where those roots join it; everything beyond the machine's reach stays where it is and rots down over three to ten years depending on species and soil moisture.
For turf, beds and paths that is fine. Surface roots that are actually in the way — the ridged fig and camphor laurel roots that crack paths across the older inner-Newcastle suburbs — can be ground separately along their length, which is charged by the metre rather than by the stump.
Species that come back
Grinding kills most trees outright. The exceptions sucker from severed roots:
- Camphor laurel, which is the single most common stump in the Hunter and among the most persistent.
- Privet, both broad-leaf and small-leaf.
- Poplar and some willows, which can throw shoots metres from the original trunk.
- Certain wattles and Chinese elm.
None of these are hard to deal with. The shoots are soft, they appear within weeks, and knocking them over as they come — or treating them once — exhausts the root reserves within a season or two. But nobody should promise you a camphor laurel stump will never re-shoot.
Backfilling properly
The worst outcome is a hole loosely filled with grindings, topped with a thin skin of soil, that settles 100 millimetres over the following year and leaves a dish in your lawn that ponds every time it rains. That matters more on the clay through Charlestown, Cardiff and Kotara than on the sand at Stockton.
Do it once: rake most of the grindings out, backfill with clean soil, tamp it in layers, mound it slightly proud to allow for settlement, then turf or seed. The grindings you removed make good mulch on beds where nothing is being newly planted.

FAQs
Frequently asked questions
Can I plant a new tree where the old stump was?
Not directly in the same hole, and not straight away. Grindings are almost all carbon and they pull nitrogen out of the soil as they break down, which starves a new planting. Either dig the grindings out and backfill with soil before planting, or plant a metre or two away from the old stump position. Waiting a season helps either way.
Will grinding damage my paving or fence?
It can if the stump is right against them. A grinder wheel needs swing room, and roots often run under a slab or footing that cannot be cut without undermining it. Where a stump sits hard against paving or a boundary wall, part of it usually has to be left, and you should be told that at quote time rather than discovering it afterwards.
How much chip does one stump produce?
More than the stump looked like it held — roughly twice its own volume, because grinding fluffs the material up and mixes it with soil. A 600 millimetre stump ground to 300 millimetres deep makes a wheelbarrow-sized mound or two. Decide before the job whether that stays on site or gets carted, because moving it later is a job in itself.
Do I need council approval for stump grinding?
Generally no, if the tree has already been lawfully removed — a stump on its own is usually not a protected tree. But if the stump is still alive and re-shooting, some councils treat it as a live tree. And if the original removal required approval, keep that paperwork with the grinding invoice.
