When it comes to tree care, most people think about pruning, watering and soil health. However, one of suburban Melbourne’s most overlooked threats to tree health is damage caused by possums.
Possums can quietly cause long-term stress to trees by stripping bark, chewing leaves and weakening branches. This can slow growth, make trees more vulnerable to pests or disease and affect their strength. Over time, the damage can lead to higher maintenance costs, safety risks or the need to completely remove and replace the tree.
So how can you tell if you’ve got a possum problem on your hands? Below are five clear signs it’s time to install a possum guard to protect your trees.
1. Your tree keeps losing bark or branches
If your tree’s branches are dropping during calm weather or you’re noticing unexplained cracks in the limbs, it could be a sign of possum activity. Possums often climb trees in search of food or nesting spots and, in doing so, can strip bark and put stress on higher branches.
Over time, this kind of wear can weaken the tree’s structure, increasing the risk of falling branches. This poses a real safety concern, particularly near footpaths, driveways, playgrounds or any area where people spend time beneath the tree.
2. There are scratching sounds at night and pellets around the tree
Possums are nocturnal creatures, most active after dusk. They often follow the same route each night — across fences, rooftops and up familiar tree trunks — as they forage and look for shelter. If you’re hearing scratching or thumping sounds at night, especially near trees or your roofline, there’s a good chance a possum is nearby.
Another telltale sign is the presence of droppings at the base of trees or along common pathways. Possum droppings are typically cylindrical and around two to five centimetres long, often found in clusters. Trees with regular possum traffic can start to show signs of stress quickly, often within just a few weeks of ongoing activity.
3. Fruit, flowers or leaves disappear overnight
Possums have a preference for ripe fruits, tender leaves and blossoms. If your fruit trees or flowering plants appear stripped overnight despite healthy growth and care, possums may be the culprits. And because they follow a consistent route, they’ll most likely return to the same trees to feed. This repeated activity can lead to significant damage, including possible defoliation.
4. Your tree is struggling to recover after pruning
It might be more than seasonal stress if your tree hasn’t bounced back and still looks thin or patchy weeks after pruning. A possum’s constant chewing, climbing and nesting can interfere with and slow a tree’s recovery.
Repeated pressure from possums can weaken trees’ energy reserves, especially in citrus, fig and ornamental trees.
5. Your tree leans or looks unstable in the wind
Weakened roots or an unbalanced canopy growth can make trees more likely to tip or lean, especially after storms. If the base looks uneven or the tree moves more than usual in the wind, hidden possum damage might contribute to the shift.
How to stop possums from climbing your trees — the right way
If you’ve spotted any of these signs, installing a possum tree guard is a smart next step. These guards are physical barriers fitted around a tree trunk to stop possums from climbing. By creating a smooth or wide surface they can’t grip, the guards block access to the canopy where most of the damage occurs.
When professionally installed at the correct height using durable, weather-resistant materials like UV-stabilised plastic, possum guards can last up to 10 years, offering reliable protection year-round.
It’s one of the most effective and humane ways to protect your trees without harming native wildlife. Done right, it also saves you time and money on ongoing maintenance, garden cleanup and costly tree repairs.
