Grinding the stump below the soil line
Below-ground stump grinding means a grinder cuts the stump and its upper roots down beneath the surface of the soil. The wood is turned into mulch and woodchip, so nothing is left sticking up above the lawn or garden bed.
Trees Down Under’s AQF Level 3-5 certified arborists set the grinding depth to suit what the space will be used for next.
How it differs from stump removal
Grinding and full stump removal are not the same job. Removal digs out the stump and as much of the root system as possible, which means heavy excavation and a large hole to backfill. Grinding works from the top down and leaves the deeper roots to break down in the soil over time.
For most Kellyville backyards, grinding is the less disruptive option and keeps the surrounding lawn and plantings mostly intact.
Why depth matters
A stump ground flush with the ground can still catch a mower blade or sit crookedly under new turf. Going below the surface leaves room for soil to be spread over the top, so the area is ready for:
- Lawn or new turf
- Paving or paths
- Garden beds and replanting
- Footings and new builds
If the tree is still standing, check whether approval is needed before it comes down. The Hills Shire Council website sets out when a permit is required for tree removal. Stump grinding itself is handled once the tree is down.
