Look For Visual Cues of Wood Rot
When you can differentiate a healthy tree from a sickly one, you’re well on your way to grasping some essential tree care basics. So, how can you tell if one specimen is injured or sick to the point that it has developed wood rot? Let’s explore the visual cues below.
Treetops
Step back and inventory the tree’s canopy. One of the most obvious signs of decay is a treetop with a few withering branches. The sparse leaves might look brown or yellow, even outside of autumn. They cling to the limbs instead of falling readily to the ground.
Branches and Trunk
Now, move closer to the specimen in question. Inspect the trunk and nearby branches for wood that looks darker or lighter than usual. You might even see a cavity or two where decay has deteriorated the heartwood.
You should also keep an eye out for:
- Mushroom-like growths indicating a fungal infection.
- Sticky, jelly-like formations in yellow, red, or brown, which suggest gummosis.
- Powdery white vein-like growths from mildew.
- Tiny holes or visible tunnels from tree pests.
If you don’t know how to tell if a tree is rotten inside, seeing these symptoms pervasively overtaking the tree is a great place to start.
Roots
Finally, move your inspection to the base of the specimen. Look for similar signs of fungus growth on the visible roots. If you look carefully, you may also see the soil cracking and pushing upward. The disrupted dirt could suggest that the tree is leaning to one side because of dead or weakened roots.
How To Tell If a Tree Is Rotten Inside Through Bark Tests
Next, experiment with the tree tissue to see how it responds to a few simple tests.
First, try the sound test. Knock or tap on the wood. If the sound of your rapping travels, the tree likely has a dead, hollow trunk.
What if the wood is still too dense to differentiate between rotting and healthy wood? Grab a screwdriver or pocket knife and gently press your tool into the wood. If the trunk readily gives way to the force, it has soft wood with wet or dry rot.
Generally, trunk tissues resist force. The interior wood looks green and moist and doesn’t succumb to light pressure. If the wood crumbles or becomes mushy, then the tree is no longer alive.
