When it comes to managing problematic trees in Sydney, homeowners and property managers must stay vigilant. While trees are essential to the urban landscape—offering shade, beauty, and ecological benefits—some species become liabilities due to rapid growth, invasive roots, structural weakness, or susceptibility to disease. Knowing which trees are most commonly removed can help you make informed decisions about planting, pruning, and when it’s time to call in the professionals.
Here are the top seven problematic trees in Sydney that often require removal and why they can become a concern.
1. Camphor Laurel
One of the most notorious problematic trees in Sydney, Camphor Laurel is known for its fast growth and aggressive root system. Originally introduced as an ornamental plant, it has become an invasive species throughout New South Wales. These trees dominate native bushland, crowding out local species, and their roots can damage pipes, pavements, and building foundations.
Because of its invasive nature, Camphor Laurel is often targeted for removal under local council guidelines. If you’ve noticed one growing near your property, it’s worth seeking advice on responsible removal options.
2. Coral Tree (Erythrina X Sykesii)
Popular for its bright red flowers, the Coral Tree is a striking but fragile addition to many Sydney gardens. Unfortunately, it’s also one of the most problematic trees in Sydney due to its tendency to develop weak wood that snaps easily in storms or high winds.
This tree often grows in parks and older properties, but due to safety concerns, especially in residential areas, Coral Trees are frequently scheduled for removal. Their limbs are heavy and brittle—posing serious risks during wild weather.
3. Liquidambar
Liquidambars are common in Sydney suburbs thanks to their beautiful autumn foliage. But what many homeowners don’t realise is that they are also a leading cause of root-related damage. These trees have extensive root systems that seek out moisture, often disrupting plumbing and breaking through retaining walls or driveways.
Because of these destructive tendencies, Liquidambar is high on the list of problematic trees in Sydney, especially when planted too close to structures. Their impressive size and aggressive roots make them difficult to manage long-term.
4. Eucalyptus (Gum Trees)
While native and iconic, some Eucalyptus species are also considered problematic trees in Sydney. Their size, shedding bark, and tendency to drop limbs without warning can become safety hazards—especially near homes, footpaths, or power lines.
Not all Eucalypts are dangerous, but large varieties like the Blue Gum or River Red Gum may outgrow their location or suffer from internal decay. Regular arborist inspections are essential, and in many cases, professional tree removal may be the safest option.
5. Chinese Tallow Tree
Although visually appealing with heart-shaped leaves and brilliant autumn colours, the Chinese Tallow Tree is a silent invader. It spreads rapidly and displaces native vegetation, making it one of the stealthier problematic trees in Sydney gardens.
Its seeds germinate easily and can overtake bushland areas. Local councils increasingly list this tree on environmental weed watchlists. If it’s growing on your property, it might be time to consider removal before it becomes unmanageable.
6. Poplar Trees
Poplars are fast-growing and provide dense shade, which makes them appealing in open landscapes. But their roots are notoriously invasive. They spread quickly and can travel long distances underground, disrupting sewer lines, irrigation systems, and even cracking building slabs.
Due to their aggressive root behaviour, Poplars are frequently among the most problematic trees in Sydney that arborists are called to assess and remove—particularly in urban environments with limited space.
7. Willow Trees
Willows are often seen near creeks and damp areas because of their preference for water. But that’s exactly what makes them troublesome. Their roots aggressively seek out moisture, invading pipes and underground infrastructure. They’re also prone to becoming waterlogged and collapsing.
As climate conditions shift and water management becomes more critical, Willows have become less favourable for residential properties and are commonly scheduled for removal across various Sydney regions.
When to Consider Tree Removal
If you’re dealing with any of the problematic trees in Sydney listed above, it might be time to call in a certified arborist. Whether you’re noticing cracking paths, blocked drains, excessive leaf drop, or concerns after a storm, acting early can prevent further damage and costly repairs.
