Most homeowners do not spend much time thinking about whether their trees are healthy.
As long as there are leaves on the branches and shade in the yard, everything seems fine.
The problem is that trees rarely fail without warning.
In fact, many dying trees spend months or even years showing signs of decline before they become a safety hazard. The challenge is that most homeowners do not know what to look for until a large branch falls, a storm rolls through, or the tree starts leaning in a way that suddenly gets everyone’s attention.
In South Florida, where hurricane season puts additional stress on trees every year, recognizing the warning signs early can help prevent property damage, expensive emergency work, and potential safety risks.
Here are seven signs a tree may be dying and when it may be time to consider professional evaluation or removal.
1. Large Dead Branches in the Canopy
A few dead twigs are normal.
Large dead limbs are not.
When major branches stop producing leaves and begin shedding bark, it can indicate that portions of the tree are no longer receiving the nutrients they need to survive.
Dead limbs are often one of the first warning signs homeowners notice, and they can become dangerous during high winds and storms.
If dead branches make up a significant portion of the canopy, it is worth scheduling a professional tree assessment.
2. The Tree Is Leaning More Than It Used To
Not every leaning tree is a problem.
Many trees naturally grow at slight angles and remain perfectly healthy for decades.
What raises concern is a tree that suddenly begins leaning or appears to be shifting over time.
This may indicate root failure, soil instability, storm damage, or structural weakness within the tree itself.
Leaning trees should always be evaluated promptly, especially before hurricane season hits hard.
3. Mushrooms Growing Near the Base
Mushrooms can be a sign that decay is occurring below the surface.
While not every fungus indicates a serious issue, fungal growth around the trunk or root flare often suggests that wood decomposition is taking place underground.
The challenge is that the healthiest-looking part of the tree may still be standing above ground while the root system is slickly deteriorating below it.
“Trees can look perfectly fine right up until they don’t,” says Gene Sherwood—ISA Certified Arborist.
4. Significant Bark Loss or Deep Cracks
Tree bark serves an important purpose. It protects the tree from pests, disease, and environmental stress.
Large sections of missing bark, deep vertical cracks, or peeling bark can indicate serious decline.
In some cases, these symptoms point to disease or internal decay. In others, they may signal structural weakness that increases the likelihood of branch or trunk failure.
5. The Canopy Looks Thin or Sparse
A healthy tree should produce consistent foliage throughout its canopy.
When large sections stop producing leaves or appear noticeably thinner than the rest of the tree, it may indicate stress, disease, root damage, or decline.
This is especially important to watch for during the growing season when healthy trees should be actively producing new growth.
6. Visible Decay or Hollow Areas
One of the most common diseased tree symptoms is visible decay.
Soft wood, cavities, hollow sections, or areas that easily crumble when touched can all indicate internal deterioration.
While some trees can survive with limited decay, extensive internal damage often reduces structural stability and increases the likelihood of failure.
This becomes particularly concerning in South Florida where strong storms can place significant stress on compromised trees.
The Florida Forest Service provides additional information about tree health and storm preparedness throughout the state.
7. Exposed or Damaged Roots
Tree roots are the foundation of the entire structure.
When roots become damaged by construction, soil disturbance, trenching, flooding, or disease, the tree’s health can decline rapidly.
Warning signs may include:
- Soil lifting around the base
- Exposed roots
- Dead sections of the canopy
- Sudden leaning
- Reduced leaf production
Root problems are often overlooked because most of the damage occurs underground where homeowners cannot easily see it.
How to Tell If a Tree Is Dying
Many homeowners assume a tree is either healthy or dead.
The reality is that decline often happens gradually.
Several of these warning signs occurring together usually indicate a larger problem that deserves professional attention. A thinning canopy combined with dead limbs, root issues, or visible decay often signals a tree that is struggling to recover.
The earlier these issues are identified, the more options homeowners typically have.
Signs a Tree Needs to Be Removed Immediately
Some situations require prompt action.
Contact a professional arborist if you notice:
- A tree leaning suddenly after a storm
- Major structural cracks in the trunk
- Large hanging limbs
- Significant root failure
- Extensive decay
- Trees making contact with structures or power lines
These conditions can create serious safety hazards and should not be ignored.
When to Call for Hazardous Tree Removal in Miami
Not every unhealthy tree needs to be removed. Some can be pruned, treated, monitored, or stabilized.
The key is getting an accurate assessment before making a decision.
At Green Wise Group, our ISA Certified Arborists help homeowners determine whether a tree can be preserved or whether removal is the safest option.
Sometimes the tree just needs a little help…and sometimes it is one strong storm away from becoming your neighbor’s problem.
