Tree stumps: grind them, mulch them in place, or leave them
Grinding, subsoil mulching and leaving a stump each suit a different plan. What each option actually leaves behind, and how to choose.
The question isn't whether a stump is ugly. It's what you're doing with the ground it's standing in. A stump outside your machinery routes is a different problem to one sitting in the middle of a paddock you want to cultivate, or a building platform you want level.
There are three real options
Grind it with a stump grinder, break it into the ground with a subsoil mulching machine, or leave it and cut it down low. Each one leaves a different surface behind, and each one suits a different plan for the land.
What grinding actually leaves
A grinder cuts the top of the stump below ground level and leaves a hole filled with wood chips. That hole settles as the chips break down, so turf laid straight over the top can dip later. Grinding also doesn't go looking for roots — the lateral roots spreading out beyond the grind zone stay where they are, which matters if you're going to dig a foundation, a pool or a new bed in that spot.
What subsoil mulching does
Subsoil mulching processes suitable stumps, roots and buried woody material within the agreed treatment area. Processed material stays in the ground; roots outside the working area or depth can remain. It can suit larger-property reclamation, but it does not guarantee level ground, land ready to sow, or ground fit to build on. Discuss future land use and follow-up assessment before choosing the method. Read the subsoil mulching guide for its limits.
When leaving it is the right call
A stump holding soil on a bank or a drainage line is doing useful work. A stump in a paddock you only slash costs nothing to live with. A big stump right against a fence, a tank or a foundation can be safer to cut low and leave than to dig out. The catch is regrowth: some species reshoot from the stump and the remaining roots, so leaving one usually means a follow-up program, not nothing.
Check what's underneath before anything moves
Stumps near a house, yard or old shed sit in the same ground as power to a shed, water lines to tanks, septic pipes, old drains and buried fence posts. A Before You Dig search shows the network assets, not the private lines you or a previous owner put in. Mark known assets and arrange locating and safe verification to asset-owner requirements. Do not assume hand digging around a live service is safe.
What to have ready before you ask for a price
How many stumps, roughly how wide across the base, what's within a couple of metres of each one, what the ground is for next, and whether the material stays on the property. That's enough to tell you whether the machine can get to them at all — which is what a site visit is for. We don't price stump work from a phone call.
No method gets every root out, and what's possible depends on access, soil and what's buried. Get a site visit before you commit to an outcome.
