Pruning a tree can reduce its canopy, remove damaged branches and improve its structure, but it does not stop root growth. A tree’s roots continue to absorb water and nutrients and provide stability, even after part of the crown has been removed. For property owners in East Fremantle, understanding this relationship is important when managing trees near driveways, fences, buildings and underground services.
If you need advice about a tree on your property, our East Fremantle tree service can help you understand suitable tree care options.
How Are Tree Roots Affected by Pruning?
A tree’s roots and canopy work together. Leaves use sunlight to produce sugars through photosynthesis, while roots absorb water and nutrients from the soil. These resources support growth throughout the tree.
When branches are pruned, the tree has less foliage available for photosynthesis. This can affect its energy balance and influence how it allocates resources to new shoots, existing roots and other parts of the tree.
However, the response varies between trees. Some may produce vigorous new shoots after pruning, while others may grow more slowly if the pruning is substantial or the tree is already under stress. Root growth does not automatically stop when the canopy becomes smaller.
The tree’s species, age, health, soil conditions, moisture levels and growing environment all influence its response. Pruning should therefore be considered a canopy management technique, not a dependable way to control roots.
Why Do Tree Roots Keep Growing After Pruning?
Roots grow in response to a range of environmental and biological factors. Their development depends on access to water, oxygen, nutrients and suitable soil conditions.
Even when a tree has fewer branches, its roots may continue spreading through available soil. Roots do not necessarily grow directly towards a house or pipe. Instead, they tend to develop where conditions provide the resources and space they need.
In East Fremantle, the conditions around each property can differ. Compacted ground, restricted garden beds, paved areas and nearby infrastructure may influence where roots can develop. The location of visible roots alone does not establish whether a tree is damaging a structure.
It is also important to distinguish between root growth and root damage. Roots can occupy soil near paths or buildings without causing a problem. Damage may occur when roots encounter vulnerable structures, exploit existing cracks or contribute to the movement of certain soils.
Can Pruning Reduce the Risk of Root Problems?
Pruning can help manage a tree’s size, shape and branch condition, but it is not a reliable solution for preventing root-related issues.
If roots are affecting a driveway, retaining wall, garden bed or underground service, reducing the canopy may not resolve the underlying problem. The appropriate response depends on the tree, the location of the roots and the type of structure involved.
Before deciding what to do, consider:
- Identify the concern: Establish whether roots are lifting paving, entering an existing crack or simply growing near a structure.
- Assess the tree: Consider its species, size, health and likely mature dimensions.
- Check the site: Look at soil conditions, available growing space, drainage and the position of nearby infrastructure.
- Choose a suitable response: Options may include monitoring, repairing vulnerable structures, modifying the surrounding area or obtaining professional advice about root management.
Pete’s Tree Worx can help with pruning overgrown trees to manage excessive canopy growth and maintain suitable branch structure. However, pruning does not stop root growth or replace the need to assess root-related problems.
Why You Should Avoid Cutting Tree Roots Without Advice
Cutting roots can be more damaging than many property owners realise. Roots help anchor a tree, absorb water and nutrients, and support its long-term health. Severing major roots may reduce stability, create entry points for decay or place the tree under significant stress.
The risk depends on factors such as root size, the tree species, its condition and how close the cut is to the trunk. Removing roots on one side of a tree may also affect its ability to withstand wind.
Before excavating near a tree, check for underground utilities and obtain appropriate advice. Do not assume that a root can safely be removed simply because it is close to a path, fence or pipe. Where a tree’s stability or a structure’s safety is in question, an assessment by a suitably qualified arborist can help identify practical options.
Managing Trees Near Buildings and Paving in East Fremantle
When a tree grows near a house, driveway, fence or retaining wall, the best approach is to assess the whole site rather than focus on pruning alone.
Look for changes such as newly lifted paving, widening cracks, exposed roots or alterations to the tree’s condition. These signs do not prove that roots are responsible, but they can indicate that further investigation is worthwhile.
Avoid pouring chemicals onto roots or cutting them back without understanding the likely consequences. Such actions may harm the tree or affect nearby soil and vegetation without resolving the original issue.
If significant work is being considered, check any applicable requirements with the Town of East Fremantle before proceeding. Local rules and approval requirements can depend on the tree, its location and the nature of the proposed work.
Frequently Asked Questions
Does cutting branches stop roots from growing?
No. Removing branches reduces the leaf area available for photosynthesis, but it does not automatically stop root growth. The tree’s response depends on its species, condition and growing environment.
Will pruning stop roots from damaging a driveway?
Not reliably. Pruning may manage the canopy, but it does not necessarily change the roots responsible for movement or damage. The cause should be assessed before choosing a solution.
Is it safe to cut roots that are lifting paving?
Not always. Cutting roots can affect a tree’s health and stability, particularly when large or structurally important roots are involved. Seek appropriate advice before removing them.
Who should I contact about tree roots near my property in East Fremantle?
If you are concerned about tree health, root growth or branches near structures, speak with an arborist or tree care professional who can assess the circumstances and explain suitable options.

Pruning is useful for managing branches and canopy structure, but it should not be relied on to stop roots from growing. Understanding the tree and the conditions around it is the best starting point for managing potential root problems safely.
