Every arborist Gold Coast will tell you they have come across multiple types of pests and diseases that harm trees. If you suspect something like fungi or borers are affecting your trees, call the services of a tree arborist Gold Coast. Experts can diagnose the problem and come up with practical solutions to eradicate tree disease.
Not treating diseased trees can cause various problems, such as failure to thrive, poor growth, rare canopy, leaf discolouration, and even death. Considering the long period a tree needs to reach maturity, keeping your green assets healthy is paramount. Calling tree loppers Gold Coast to take care of your trees is an excellent investment, as healthy, beautiful trees are known to increase your property’s value.
Why Trees That Have Pests Are Dangerous.
One of the questions that we get asked a lot is: ‘Are dead or diseased trees dangerous?’
The short answer is yes, dead or diseased trees are dangerous. The more time goes by, the riskier they become. Their structural integrity is affected, and chances of falling increase day by day.
Timber in a dead tree begins to break down once the tree has succumbed. Dead wood is understandably weaker than live wood because it starts to decompose. Dead timber becomes brittle, begins to rot, and branches start to fall too. The question is not ‘Will it fall?’, but ‘When?’
In the case of a diseased tree – it will have dead parts that can fall or will die completely one day. A falling tree can cause all kinds of damage, such as damaging fences, falling over property or vehicles, and even injuring people. If you notice one of your trees has died or is on its way out, you need to remove it as soon as possible. If the tree falls over a house or a car, you will be dealing with more considerable expenses (repair, clean-up, fines and of course stress!).
Signs That You May Have Tree Pest or Disease
Signs of tree disease can be very subtle, and this is why many people miss them. You need to inspect your trees thoroughly every few months or get a tree arborist Gold Coast to make regular assessments.
Here are the main signs you need to look for to detect tree pests or disease:
Look for brown and brittle bark on your trees. In dying trees, the bark becomes loose and starts to fall. Vertical cracks and missing bark appear. As the cracks deepen, they cause weakness, making the tree more vulnerable to storms and extreme weather.
Cracking and Swelling
Not all cracks forming on the trunk of a tree are signs of disease or pests, but you should carefully investigate gaps and splits going more profound than the bark.
Swelling can be caused by freeze damage and environmental injury and also by a genetic predisposition. However, burls can also develop as a result of bacteria or fungi invasions. Careful about removing burls, as they leave large wounds in the tree’s trunk.
The bacterial wet wood is the most common cause of sap oozing out of the tree. The problem with leaking fluid is that it robs the tree of nutrients and weakens it.
Some trees, on the other hand, are prone to bleeding sap. These tree species are beech, birch, elm, grape, linden, maple, poplar, and walnut. They should be pruned by tree loppers Gold Coast after their leaves are fully developed, in late spring or early summer.
Presence of Pests and Frass
If bark beetles and carpenter ants have invaded the tree, this is a sign that they have found a weak and dying host. Even if you don’t see the actual insects, you can see their excreta. Mushrooms growing on the tree or at the tree’s base can also represent a sign of rot.
If you have noticed holes in the bark of your trees, it is not good news. Wood-boring insects and birds cause them. For instance, adult beetles enter trees to lay their eggs there. They excavate galleries inside the tree and feed on the living cambium layer. If the entire cambium layer is dead, the tree is in serious trouble as water and nutrients have no connective tissues to transport them where the tree needs them. Pests create holes of different sizes and shapes, from round and D-shaped to horizontal or longitudinal scars.
A diseased tree will have fewer leaves compared to a healthy one. Arborist Gold Coast services recognise dying trees by looking at foliage health. During the growing season, your tree should have lush green leaves, not brown and brittle foliage. Don’t mistake the leaves of a dying tree with leaves that fall in autumn; the former still cling well to the tree instead of dropping to the ground.
In stressed coniferous trees, needles start to look red, brown, or yellow.
Determining damage to the roots is not so simple because they run deep into the ground. Roots can be damaged during excavation or construction projects. If you have trees with partially exposed roots, exposure to elements can cause reduced foliage, slow growth, dead branches, small yellow leaves, and wilted brown leaves.
Odd Growing Patterns
Has the tree in question suddenly leaned? A structural imbalance is a severe symptom; if the tree leans at more than 15 degrees, it probably has root damage. Extreme wind can cause this issue too, and even the most giant trees seldom recover from wind damage.
Failing the Scratch Test
Right under the outer bark layer, you can find the cambium layer. It should be green and have a certain amount of moisture. In a dying tree, the cambium is dry and brown. Use a pocket knife to remove a small patch of bark and determine the cambium layer’s condition.
Most Common Tree Pests Found in South East Queensland by Arborist Gold Coast
Trees can be affected by different pests in every part of the world. In South East Queensland, our arborist Gold Coast experts commonly deal with the following problems:
Termites feed on dead trees and stumps, which is a good thing, but the problem is that these hardworking insects can also attack your house. They live in colonies of around 250,000 individuals, each with its specific role to play. There also are termites that attack living plants and trees (white ants). Signs of termite infestation include wood shavings at the tree base, mud tubes on the tree bark, hollow tree trunk, and termites present in the trunk and the soil around the tree base.
Tree borers lay their eggs inside tree trunks, and their larvae eat their way through the tree’s living tissues. These insects sever vital transport tissues and weaken branches until they break under their weight. Check for tiny holes these pests cut into trunks, branches, and stems. Frass that insects leave behind them as they excavate tunnels is also present.
Brown Root Rot
Unlike the previous two pests, which are insects, brown root rot is a fungal disease. The pathogen is called Phellinus noxius, a fungus that spreads through contaminated soil, groundwater, surface water, and even through the air. If you suspect this disease has infected a tree, avoid it to prevent spreading the fungi’ spores and call an arborist Gold Coast immediately.
Poinciana Looper Moth
The beloved poinciana tree is grown as a street tree across South Queensland. Unfortunately, the looper moth’s caterpillar can attack this beautiful tree, causing defoliation. The pest becomes a nuisance to people when mature caterpillars start falling from the trees. The most significant number of infestations occur in wetter seasons.
How to Avoid Pests and Diseases?
We tend to take trees and their cooling shade for granted, but we should take more care of our green companions. The first step of keeping your trees healthy is prevention. You can take preventative measures alone or with the help of arborist Gold Coast services:
Monitor your Trees
Regular check-ups enable early detection of problems when the pest population is low and easier to eradicate. You will need to check for pests every season, as they attack at different times of the year.
Keep Plants and their Beds Clean
Dissuade harmful insects from finding a host in your tree by removing the old leaf litter and rotating annual crops from one part of the garden to another.
Plant the Right Trees
Choose local species that are pest resistant. Ensure each tree’s best conditions, as planting a tree in the wrong place will cause stress and weakness from the beginning.
Plant Multiple Species
If all your trees are from the same species and are affected by a pest, this can wipe out the entire population. It is preferable to have several types of trees, so you still have something left in case of a pest attack.
Apply the Right Treatments
Encourage the reproduction of beneficial insects in your yard, such as ladybugs, lacewings, and parasitic wasps, as they are the enemies of insect pests. If the situation is out of control, contact the Treestylin tree arborist Gold Coast for assessment and treatment.
