What Happens to Tree Roots After a Tree Is Removed?
Cutting down a tree doesn’t always mean the roots are gone.
When a tree is removed, most people focus on what they can see above ground. The trunk is cut down, the branches are cleared, and the yard looks open again. But underneath the soil, the root system can remain for months or even years.
At Harvey Tree Care, we often get asked what happens to tree roots after removal, especially when homeowners are planning new turf, paving, fencing, garden beds, or building work. The answer depends on the tree species, root size, soil conditions, and whether stump grinding or root removal is completed.
Here’s what WA homeowners should know.
Do Tree Roots Keep Growing After Removal?
In most cases, once the tree has been cut down and the stump is properly dealt with, the roots stop actively growing. Without leaves, the tree can no longer produce energy through photosynthesis, so the root system eventually begins to die back.
However, this does not always happen straight away.
Some species can continue to push out new shoots from the stump or roots if the tree has not been fully removed. This is especially common with fast-growing or resilient species, including some gums, wattles and other hardy trees found across Western Australia.
That is why stump grinding is often recommended after tree removal. It helps stop regrowth at the source and clears the area properly.
How Long Do Tree Roots Take to Break Down?
Tree roots can take a long time to decompose underground. Small feeder roots may break down relatively quickly, while larger structural roots can remain in the soil for years.
The breakdown period depends on:
- The size of the root system
- The species of tree
- Soil moisture levels
- Soil type
- Whether the stump remains
- How much of the root system was removed
In some cases, old roots can slowly rot underground and create soft or uneven patches in the yard. This can become a problem if you plan to lay turf, paving, concrete, or build over the area.

Why Leaving Roots Behind Can Cause Problems
Many roots naturally break down without causing major issues. But in some situations, leftover roots can create problems around the property.
Regrowth can appear
If the stump or larger roots are still alive, new shoots may appear. This can make the area look messy and create ongoing maintenance work.
Regrowth is especially frustrating when the tree was removed because it was in the wrong location, blocking access, or causing damage.
Roots can interfere with landscaping
If you are planning a new garden bed, lawn, driveway, path, fence, or shed, old roots can get in the way. They can make digging difficult and prevent surfaces from sitting level.
Even after the roots start breaking down, the soil can shift or sink as the timber decomposes underground.
Old roots can attract pests
Decaying timber can attract insects, including termites, ants, and borers. While not every root system will become a pest problem, leaving large amounts of buried wood close to the home can increase the risk.
This is one reason many homeowners choose professional tree and stump removal rather than leaving the stump and roots to rot naturally.
Roots can continue affecting pipes or structures
If roots were already causing damage to plumbing, septic systems, paving, foundations, or retaining walls, cutting down the tree may not solve the issue immediately.
Large roots can remain in place and continue to block access, hold moisture, or interfere with repairs. In these situations, tree root removal may be needed.
What Does Stump Grinding Do to the Roots?
Stump grinding removes the stump below ground level using a specialised grinding machine. This breaks the stump into woodchips and removes the main growth point of the tree.
Stump grinding helps by:
- Preventing most regrowth
- Removing the visible stump
- Reducing trip hazards
- Clearing space for landscaping
- Helping the remaining roots break down over time
- Improving the look and usability of the yard
While stump grinding does not remove every single root underground, it removes the main stump and upper root crown. For most residential jobs, this is enough to stop the tree from coming back and make the area usable again.
When Is Full Root Removal Needed?
Full tree root removal is not required for every tree. In many cases, grinding the stump is enough.
However, root removal may be recommended if:
- Roots are damaging pipes or septic systems
- Roots are lifting paving or concrete
- Roots are affecting a fence, wall, or building foundation
- You are planning construction in the area
- The tree species is known for aggressive regrowth
- Large surface roots are creating trip hazards
- The stump and roots are close to the home
At Harvey Tree Care, we assess the site and recommend the right level of removal based on your plans and the risk involved.
Can You Build Over Old Tree Roots?
It is usually best to remove major roots before building, paving, or concreting over the area. Old roots can decay over time, which may cause the ground to settle unevenly.
This can lead to:
- Cracked paving
- Sunken turf
- Uneven concrete
- Fence movement
- Drainage problems
If you are planning landscaping or construction after a tree removal, it is worth dealing with the stump and root system properly first.
What Happens to Roots After Palm Tree Removal?
Palm roots are different from many other trees. Palms do not usually have the same large woody root structure as mature shade trees, but their root ball can still be dense and difficult to remove.
After palm tree removal, stump grinding is often needed to clear the base and stop the area from becoming a hard, messy obstacle in the yard.
Palm stumps can also be tough and fibrous, which makes DIY removal difficult.
Can You Remove Roots Yourself?
Small roots near the surface may be manageable with hand tools, but larger root systems are a different story. Digging out roots manually can be time-consuming, messy, and risky if services are nearby.
DIY root removal can cause problems if you accidentally damage:
- Plumbing
- Reticulation
- Electrical lines
- Fences
- Paving
- Nearby trees
Professional arborists use the right equipment to remove roots safely and efficiently, with less disruption to the surrounding area.

Frequently Asked Questions
Do tree roots die after the tree is cut down?
Usually, yes. But some species can produce regrowth if the stump or root crown is left behind.
Will stump grinding remove all the roots?
Stump grinding removes the stump and main root crown, but not every underground root. For most properties, this is enough. Full root removal may be needed for plumbing, paving, or building issues.
Can old roots damage my new lawn or paving?
Yes. As roots decay, the soil may settle unevenly. Removing major roots before landscaping can help prevent future problems.
Do roots attract termites after tree removal?
Decaying wood can attract pests, including termites. Stump grinding helps reduce this risk by removing the main food source.
