How to kill a tree stump: cut it flat and low, drill holes in the fresh cut, then apply a registered stump killer exactly as the label directs. The most common mistake is waiting too long after the tree comes down, because the stump seals over and the product no longer soaks in.
This guide covers how to kill a tree stump, how to remove tree stumps by hand or by grinding, what to do with large stumps, and what a Sydney stump grinder charges.
Key points
- Treat a stump soon after the tree is cut, and in Sydney any season works, though dry weather gives chemicals and drilling the cleanest result.
- For the chemical method you need a drill, a registered stump killer, gloves and eye protection, and you must follow the product label exactly.
- Check your council’s tree rules before any cutting, and leave large trees and work near power lines to a qualified arborist.
- A Sydney stump grinder typically charges about $170 to $1,025 per stump depending on its size (October 2026).
When to kill a tree stump in Sydney
Stumps can be treated at any time of year, but the timing changes how well each method works. Suckers from stumps of species such as privet often appear in humid Sydney summers.
| Season | What to do | Why |
|---|---|---|
| Spring (Sep–Nov) | Treat the fresh cut and watch for new shoots. | Sap is moving, so growth restarts quickly if the stump is still alive. |
| Summer (Dec–Feb) | Treat in the cooler part of the day and remove any suckers. | Hot weather speeds regrowth and dries out the surface. |
| Autumn (Mar–May) | Treat, cover and let the stump begin to rot over winter. | Mild, damp weather helps a treated stump start to break down. |
| Winter (Jun–Aug) | Dig out small stumps or book a stump grinder. | Damp soil is easier to dig, and the stump is out of the way before spring growth. |
What you need to kill a tree stump
| Item | What it’s for | Tip |
|---|---|---|
| Registered stump killer (for example from Bunnings) | Killing the roots through the cut surface | Use only as the label directs, and never mix products. |
| Cordless drill and long bit | Drilling holes for the product | Use the hole size and spacing printed on the label. |
| Gloves, eye protection and closed shoes | Personal protection | Wear the PPE listed on the product label. |
| Small paintbrush or applicator | Applying the product to the cut surface | Keep it for stump killer only. |
| Tarp or heavy plastic | Covering a treated stump | This keeps rain off and pets and children away. |
| Spade, mattock and loppers | Digging out small stumps and roots | Look for underground pipes and cables before you dig. |
How to kill a tree stump: step by step
- Check your council’s tree rules before any cutting, as many Sydney councils require approval to remove trees above set sizes or of listed species.
- Cut the stump as low and flat as you can, and treat the cut surface as soon as possible after cutting.
- Wear gloves, eye protection and the PPE listed on the product label, and keep children and pets well away.
- Drill holes across the top of the stump, following the hole depth and spacing on the product label (indicative — check the product instructions).
- Apply the registered stump killer to the holes and fresh cut exactly as the label directs, and never use more than the label allows.
- Avoid spraying or pouring on windy days or before rain, and keep any runoff out of drains, gardens and waterways.
- Cover the stump with a tarp or heavy plastic to keep rain, pets and children away from the treated surface.
- Wait for the stump to die and begin to rot, which can take months or longer depending on the species (indicative — check the product instructions).
- Cut off any suckers that appear and treat them according to the label, then break up or dig out the dead stump once it softens.
How to kill a tree stump vs remove it
Killing a stump leaves it in place to rot, while removal takes the stump out. Pick based on how fast you need the space.
| Method | Speed | Best for | Watch-outs |
|---|---|---|---|
| Chemical stump killer | Slow | Small to medium stumps you can leave for a while | Label-only use, and it can harm nearby plants if misused. |
| Natural rot | Very slow | Stumps in a bed or corner you can ignore | May shoot suckers and can harbour termites, so call a licensed pest controller if you suspect them. |
| Digging out by hand | Slow, hard work | Small stumps with shallow roots | Heavy work, and services may sit underground. |
| Stump grinding | Fast, often same day | Medium and large stumps, or lawn restoration | Needs access for the machine, and noise rules apply. |
| Burning | Unpredictable | Rarely suitable in suburban Sydney | Often restricted by council and fire rules, so check first. |
How to remove a tree stump by hand: small stumps and DIY stump removal
If the stump is small and the roots are shallow, DIY stump removal is possible with basic tools and patience.
- Check for underground pipes and cables before you dig, and book a licensed trade if you find any.
- Dig a trench around the stump to expose the main roots, then cut them with loppers, a root saw or a mattock.
- Rock the stump back and forth to loosen it once the larger roots are free, using a long lever for extra force.
- Remove the stump from the hole, fill it with soil and compost and compact it lightly to avoid sinking.
- Keep your back and knees safe, and ask for help rather than lifting a heavy stump alone.
How to get rid of tree stumps: removing large tree stumps
Large stumps and big root systems are heavy, dangerous work for a home gardener. This is where a stump grinder earns its price.
- Book a professional stump grinding service for stumps that are wide or have large surface roots.
- Ask the operator to grind below the surface, so you can plant or lay turf over the area afterwards.
- Expect noise during grinding, and note NSW rules do not allow powered tools to be heard inside a neighbour’s home before 7 am, or before 8 am on Sundays and public holidays.
- Check the access, because grinders need a clear path and may not fit through narrow side gates.
- Ask what happens to the woodchips, and whether taking them away is included in the price.
Common mistakes with how to kill a tree stump
- Waiting weeks after the tree is cut, so the surface seals over and the product doesn’t soak in.
- Using more product than the label allows, which can harm nearby plants, soil and waterways.
- Pouring rock salt, bleach or other home remedies on the stump, because salt and bleach can damage soil for years and spread to nearby plants.
- Leaving the treated stump uncovered where children or pets can reach it.
- Burning or lighting a stump without checking local fire and council rules.
- Ignoring suckers, which keep the root system alive and can pop up across the lawn.
When to call a gardener (or a licensed specialist)
- The tree is still standing and taller than you can safely handle from the ground, which is a job for a qualified arborist.
- Any limbs or trunks are near power lines, which only qualified arborists should work around.
- You need council approval to remove the tree or stump, as rules vary across Sydney.
- The stump is large or has big roots, and you want it ground below the soil.
- Termites or other pests are in the stump, so book a licensed pest controller.
- Weeds or suckers need spraying for fee or reward, which requires a licensed ground applicator in NSW.
