What are the signs that a tree might fall and needs immediate attention?
Apr 20, 2025
Ever stood under a towering tree and wondered if it's safe? Trees are fantastic additions to our yards—they offer shade, beauty, and even boost property value. But sometimes, they can become hazardous without us realizing it.
In this blog, we'll chat about how to recognize the warning signs that a tree might fall. From leaning trunks to fungi at the base, knowing what to look for can help you prevent potential damage or injury.
Signs a tree might fall
Leaning trunk and soil heaving
One of the most obvious signs is a leaning trunk. If your tree is leaning more than 15 degrees, it could indicate wind or root damage. Especially if the lean is sudden after a storm, it's a red flag that the tree might fall soon. Also, look for cracked or raised soil—known as soil heaving—at the base of the tree. This suggests the roots are destabilizing, which can lead to the tree toppling over.
Missing bark and deep marks
Check for missing bark or deep marks on the trunk. These can signal dead sections due to infection, wounds, or fungus. Weakened spots make it more likely for the tree to split and fall. Lightning strikes may also leave long streaks of missing bark, compromising the tree's stability.
Fungus or mushrooms at the base
Spotting fungus or mushrooms growing around the base of the tree? That's a sign of root rot. Decayed roots weaken the tree, making it vulnerable to strong winds and increasing the risk of falling. Even the presence of carpenter ants can be a red flag—they're attracted to decaying wood.
Cracks in the trunk and multiple trunks
Cracks in the trunk are serious business. Deep cracks compromise the structural integrity of the tree. Over time, these cracks can worsen, eventually causing the tree to fall. If your tree has multiple trunks forming a V or U shape, that's another sign of potential structural weakness.
Dead or falling branches
Are there dead or falling branches in your tree? This suggests it's not getting enough nutrients, leading to weakened branches that can be hazardous. In this state, the entire tree may be at risk of falling. While professional pruning can help, it's important to assess whether the tree is healthy overall.
Trees near water bodies
Trees growing near water bodies may become waterlogged, leading to decaying roots. Wet soil or standing water around the roots accelerates decay and increases the risk of the tree falling. If your tree is near a lake, river, or even an area with poor drainage, keep an eye out for signs of root problems.
Closing thoughts
Being aware of these warning signs can help you prevent potential disasters. Regularly inspecting your trees for issues like leaning trunks, missing bark, or fungi at the base can make all the difference. If you spot any of these signs, it's best to contact a certified arborist for an expert evaluation.
