You walk out to your yard one morning and notice mushrooms popping up along the base of a tree. Maybe they weren’t there yesterday, or maybe you just never paid attention. Either way, it catches your eye and not in a good way. Mushrooms growing on trees can seem random, but they’re often a clear signal that something is happening below the surface.
If you live in Reading or nearby areas, you’ve probably dealt with plenty of yard issues from season to season. But mushroom growth around or on a tree? That’s one problem you don’t want to ignore. While mushrooms might seem harmless or even a little quirky, they can be a warning sign of internal decay or infection inside the tree. The good news is, once you know what to look for, you can catch the problem early.
Common Causes Of Mushroom Growth On Trees
Mushrooms aren’t just popping up out of nowhere. When they appear on or around trees, it usually means something deeper is going wrong. Here are a few of the top reasons trees in Reading may start growing mushrooms.
1. Fungal Infections
Fungi are the most common reason why mushrooms show up on trees. These infections often start from wounds in the tree bark or base, which give the fungus an easy way in. Once inside, the fungus begins breaking down the tree’s internal structure. The mushrooms you see are the visible part of that fungi trying to complete its life cycle.
Common fungal types in this region include Armillaria, also known as honey fungus, which can form clusters at the base, and Ganoderma, which produces shelf-like mushrooms that resemble small pancakes. These fungi aren’t just surface-level either. Once they take hold, they can stick around and do damage for years if ignored.
2. Tree Decay
Sometimes mushrooms pop up because the tree is already rotting inside. Decay can happen for a number of reasons like storms, poor pruning, or simply old age. When the internal wood becomes soft or damaged, it creates the perfect spot for fungal growth. You might not see cracks or weak branches right away, but the presence of mushrooms is a strong sign that decay is forming deep inside the tree.
3. Look out for:
– Mushrooms forming directly on the trunk
– Cracks in the bark
– Soft or crumbly patches of wood
– Cavities or hollow sounds when tapped
4. Moisture Issues
Trees that sit in damp or soggy soil have a higher chance of developing mushrooms. Excess water encourages fungal spores to grow and spread. This is especially common in yards with poor drainage or after very wet summers. In Reading, these issues are made worse by heavy clay soil or shaded yards that stay damp longer than others.
Common contributing factors include:
– Clay-heavy or compacted soil that traps water
– Shaded areas under other trees or buildings
– Mulch piled too high against the tree trunk
– Overuse of sprinklers or irrigation systems
A single mushroom here or there might not scare you, but when you start seeing groups of them or mushrooms growing out of the bark, it’s time to pay attention. Finding the source early can help you avoid serious problems down the line.
Dangers Of Ignoring Mushroom Growth
Seeing mushrooms on a tree and doing nothing about them could lead to some serious trouble. First, they often mean the tree is rotting from the inside. That makes the structure much weaker, even if everything still looks normal on the outside. A tree that’s hollow in the middle or has decayed roots is more likely to snap or fall during storms or even a windy afternoon.
You may not always get a warning. Big limbs could fall unexpectedly or the entire tree might lean suddenly if enough strength is lost. That’s a big problem in places like Reading, where yards are close together and trees often stand near homes, fences, or walkways.
Fungal infections can also spread underground. Through connected root systems or shared soil, the fungus that started with one tree might move on to infect others nearby. That’s even more reason to act early if you notice something off.
Spotting Trouble Early
If mushrooms are growing on a tree in your yard, it’s worth stopping to take a closer look. Don’t just focus on the mushrooms—check other parts of the tree too. Problems usually build slowly, and many signs aren’t easy to notice right away.
Here’s what to look for:
– Mushrooms sprouting from the trunk or large roots
– Bark peeling or pulling away from the tree
– Wood that feels soft or spongy when pressed
– A slanting or leaning tree when it didn’t lean before
– Reddish or black stains at the bottom of the trunk
If one or more of these things show up along with mushroom growth, the tree may be dealing with a deeper issue. A trained tree expert can tell you what’s going on and what needs to happen next. They know how to check for damage inside the tree and spot risks before they cause real damage.
Simple Ways To Prevent Fungal Trouble
There’s no way to promise your trees will never get infected, but a little care can lower the chances. Healthy trees are better at fighting off fungus and recovering from small wounds that might otherwise allow infections in.
Basic care tips to follow:
– Trim dead or dying branches before they cause problems
– Keep mulch at a safe distance from the trunk to stop moisture buildup
– Make sure water doesn’t sit at the base of the tree after it rains
– Avoid piling dirt against the tree when doing landscaping
– Be smart about watering—less water in cool months is better
Trees that are already very damaged or falling apart from the inside may need to be removed. That can feel like a tough call, but ignoring decay can lead to big repair bills or even accidents. It’s always safer to remove a risky tree once the problem becomes too advanced to fix.
Signs Matter: Pay Attention to Your Trees
When mushrooms pop up on or near a tree, it’s not something to shrug off. They’re often signs that your tree is in trouble, with the problem starting from the inside out. Whether it’s caused by fungi, decay, or moisture that never dries up, mushroom growth tells you it’s time to take a closer look.
Strong, healthy trees are a great part of any yard, but only if they’re safe and solid. It pays to get in the habit of inspecting your trees from time to time—especially older ones or any that have been through rough weather. Spotting problems early gives you more options and fewer surprises. Keeping your trees in good shape helps protect your yard, your house, and your peace of mind.
