Find out whether your tree has begun rotting below.

Why Do Standing Trees Rot?
Many people think dead trees have already fallen to the ground and can’t stand up. While dead, rotting wood absolutely compromises the specimen’s structural integrity, it doesn’t necessarily mean the tree will come down. Bacteria, pests, and fungi may take years to chip away at tree health, so trees can remain standing until a substantial force topples them.
How To Tell If a Tree Is Rotten Inside
If you aren’t sure whether the tree on your property is gradually decaying, the specimen probably shows no obvious signs of structural weakness. You’ll have to look more closely at the tree to verify its current health. Our tree professionals list some tell-tale signals of wood rot in the steps below.
Examine the Trunk
The tree trunk is the biggest and most obvious visible area of any specimen. You can walk right up and circle the trunk to look for:
- Trunk holes: Look for cavities that reveal a hollow trunk inside. These cavernous openings mean the rot began in a localized area but spread throughout the tree.
- Pests or fungal growth: Check for tiny holes or tunnels indicating bug activity. You may also notice growths that resemble mushrooms or lichens spreading across the trunk.
- Shed bark pieces: Learning how to tell if a tree is rotten inside involves testing the bark quality. If you can see bark peeling or discover pieces of bark littering the ground, then your specimen is rapidly losing its protective surface layer.
Dig Just Beneath the Surface
Trees are a picture of health when they have strong wood that doesn’t succumb to pressure. Sick or dead trees have wood that readily caves in when you push it. The trunk might crumble dryly, or you might get your hands filthy with slimy, wet-rotted tissues (softwood decay)
You can test the wood’s integrity with a sharp tool by carefully scraping some of the bark and trunk. Does the wood beneath the bark’s surface look green and have that pungent, earthy odor that healthy plants possess? Then, the wood is still thriving.
Survey the Tree’s Crown
Step back to survey the treetop. Can you see significant branch dieback, patches with no foliage, or dead leaves clinging to the limbs? A balding, straggly crown may mean the rotting wood cuts off the canopy’s nutrient supply.
