Trees are a vital part of our landscapes, providing shade and oxygen and reducing erosion. But sometimes, trees get sick.
So, what does an unhealthy tree look like? An unhealthy tree often has peeling bark, cracks, hollow areas, poor leaf growth such as smaller or sparse leaves, early fall color, mushrooms around its base, or dead branches. These signs indicate the tree is stressed by issues like disease, pests, drought, damage, or poor nutrition that require treatment to improve health.
Knowing the signs of an unhealthy tree can help you get it treatment or perform tree removal before it becomes a hazard.
If your tree's bark is peeling off in large chunks or sheets, that's a red flag. Healthy bark expands as the tree grows. When bark peels, it indicates the tree can't produce new layers fast enough to keep up with growth. This happens when trees are stressed by disease, pests, drought, etc.
Flaking bark also opens your tree to insects and infection. I recommend hugging such trees very gently so as not to accelerate the peeling.
Cracks in bark and wood provide an all-access pass for insects and fungi to munch their way deep into your tree. Vertical cracks between bark ridges often form when trees bend and swell in the wind. Horizontal cracks across branches or the trunk indicate interior damage.
If your tree wasn't being blown around like a napkin last night, cracks likely mean trouble. I prescribe an arborist visit and possibly some tree therapy to get to the root of the issue.
A hollow tree trunk or branches puts structural integrity at risk. Decay and cracks allow moisture inside, furthering internal rot. Gaps also offer free space for wildlife or insect infestations.
Before things get ugly, have an arborist assess whether pruning and bracing can help. If more than half the trunk is hollow, removal may be safest.
When a tree can't produce enough healthy new leaves, it can't feed itself via photosynthesis. Signs include smaller, sparser leaves and short twig growth. Leaves may be light green, yellow, or brown.
This often indicates nutrient deficiency, disease, thirst, or critter damage. Boost water and fertilizer per an arborist's instructions. Pests and illnesses need proper treatment.
Leaves turning color and dropping prematurely, especially at branch tips, likely show stress. Drought, disease, trenching, and root damage can all cause this.
Rake up and dispose of diseased leaves to limit spread. Improve drainage, fertilize, and deep water if needed. Removing dead branch tips encourages regrowth.
Mushrooms feasting on your tree's roots form fungal partnerships, eventually leading to rot. If you spot clusters at the base, suspect trouble. The problem may stem from overwatering, poor drainage, damaged bark, or dead roots.
Cut back on watering if that's the culprit. An arborist can check for other issues and patch wounds. Removing mushrooms won't treat the underlying problem. Think of them as red flags rather than causes.
A few dead twigs here and there are normal self-pruning. But significant dead branches indicate ill health demanding attention. After ruling out recent weather culprits like snow or wind load, look for signs of disease, soil issues, stem damage, or circling roots.
Prune out dead and dying branches, disposing of debris properly. Boost care as needed and monitor for recovery or worsening problems. Catching issues early makes treatment more likely to succeed.
Keeping a close eye out for signals of sickness helps prevent losing landscape trees. Peeling bark, cracks, poor leaf growth, and mushrooms at the base all wave red flags. At the first sign of trouble, call an arborist to assess and advise. With quick care, many trees bounce back.

What does an unhealthy tree trunk look like?
An unhealthy tree trunk may have peeling bark that falls off in large pieces, indicating the tree is stressed and cannot generate new bark fast enough. Cracks in the trunk, whether vertical between ridges or horizontal across the surface, show structural damage that allows entry of insects and disease. A trunk with hollowed-out areas or internal rot poses a serious risk of breaking and falling due to weakened wood strength. Mushrooms growing at the tree's base are a clear red flag for root and trunk infection that requires treatment right away.
How do you revive an unhealthy tree?
The first step in reviving an unhealthy tree is to diagnose the specific problem causing stress, whether disease, pests, drought, damage, or other issues. Once the underlying cause is identified, the appropriate treatment can be applied, including pruning out dead limbs, controlling pests, adjusting irrigation, mulching, and mineral supplementation under the guidance of a professional arborist.
What does a bad tree look like?
A tree in poor health gives off many visible warning signs that trouble is afoot. Peeling bark that falls off in large, flat pieces indicates the tree is struggling to grow new protective layers fast enough. Sparse and undersized leaves that are light green, yellowed, browned, or dropping early show the tree lacks nutrients for photosynthesis. Shrooms clustering around the tree's base mean fungal infections are munching away on the roots underground. Significant dead branches or splits and cracks in the bark make the tree susceptible to pest infestation and decay.
Can you tell if a tree is diseased?
There are several key signs that may indicate a tree is suffering from disease. Unhealthy looking bark that is peeling, cracking, or developing growths may point to pest, fungal, or bacterial infection. Poor leaf quality with leaves that are wilted, stunted, yellowed, or falling early shows the tree is under stress. Mushrooms at the base of the tree are a giveaway that root fungi have moved in. Dead or dying branches crown a clearly weakened tree struggling with illness that calls for prompt treatment. Paying attention to these visual cues allows diseased trees to be identified and managed early before the problems become terminal.
