For new turf, grind the stump at least 200 to 300 mm below finished soil level, deeper if you plan to plant or build over it. Trees Down Under’s certified arborists do it properly across Sydney. Call 0475 463 597 any time for a free inspection and same-day quote.
For a lawn-only area, the arborist grinds the stump well below ground level, clearing the woody mass from the root zone so there is soil above it for turf to root into. Deeper is not automatically better. The aim is a clear zone that can be backfilled and compacted, not maximum depth.
Depth is set by stump diameter, timber hardness, and any buttress or surface roots running out from the base.
Wood left too close to the surface decays over time. That can mean sinking patches, fungus and sucker regrowth, and a hard layer that stops turf roots getting established.
Grind to the depth the finished surface needs, not the deepest the machine can reach. Over-digging only creates more ground to rebuild properly.

Our arborists assess the stump on site and plan the grind around your final surface. If the tree is still standing, tree removal comes first, and council permit requirements should be checked beforehand. Call 0475 463 597 any time to arrange a free inspection and same-day quote.
A wide, dense stump needs more grinding than a small, soft one. Trees Down Under’s AQF Level 3 to 5 certified arborists check the diameter and timber type first, then set the grinding depth to clear the woody mass from under the turf root zone. If a tree is still standing, check council permit requirements before any tree removal goes ahead. For stump enquiries, call 0475 463 597 any time for a free inspection and same-day quote.
The stump is rarely the whole job. Buttress and surface roots can reach well past the trunk, so the main roots are ground out as part of the site plan. The wood chips and mulch are cleared as part of the full site clean-up.
Where roots run under pavers or toward a slab edge, an aggressive grind can disturb bedding sand or crack edging. The operator may limit depth or change the cut angle. Narrow gates and soft lawns may call for a pedestrian grinder, which gives better control near walls and tight corners.
Soil decides how the ground behaves once the grinder leaves, so Trees Down Under’s AQF Level 3 to 5 certified arborists check it before they set the grinding depth.
Sandy soils can slump if they are over-excavated or left uncompacted. Grinding deeper than needed only adds to that risk before turf goes down.
Clay soils hold their shape after grinding, but they may heave or shrink with moisture changes, which can shift the finished level of new turf.
Either way, the aim is a stable, level surface. For a free inspection and same-day quote, call 0475 463 597 any time.
Grinding to the right depth is only half the job. What goes back into the hole decides whether your new turf stays level or sinks a few months later. Trees Down Under’s AQF Level 3 to 5 certified arborists treat backfill and compaction as part of the stump grinding service, not an afterthought, because it is the step homeowners most often overlook.
Loose wood chips and mulch settle and break down over time. If they are left uncompacted, or pushed back in without being mixed with clean soil, the ground can slump long after the lawn is laid. Sandy soils are especially prone to this, particularly when the grind goes deeper than the site needs.
A sensible finish before laying turf looks like this:
– Remove the bulk of the grindings and replace them with clean soil
– Backfill in layers and compact each one
– Level to suit the surrounding lawn, allowing a little extra for settling
– Rake the surface and lay the new turf
If the stump is part of a larger job, the same crew can handle tree removal and the full site clean-up in one visit. To book a free inspection and same-day quote, call any time on 0475 463 597.
For most lawns, stump grinding is enough. Once the stump is ground below ground level and the hole is backfilled and levelled, turf can root over the top. Full stump removal, where the stump and main roots are dug out, is usually only needed when a new structure, deep footing or large garden bed is planned over the spot. Our guides explain the difference between grinding and removal and whether grinding is necessary after tree removal.
Old, long-standing stumps can often still be ground out. Hard, dry timber just takes more time, and our guide to grinding old stumps covers what to expect. If you are also planning tree removal, which Sydney homeowners often combine with grinding, we can handle both in one visit.
