Is That Tree Dangerous? 8 Warning Signs South Florida Property Owners Shouldn't Ignore

Hurricane season officially ends November 30, and for most of us that's a relief. But fall and winter are actually one of the best times to take a hard look at the trees around your home or community. The leaves aren't hiding as much, the weather is mild, and if a tree does need work, you have months to deal with it calmly instead of scrambling when the next storm shows up on the forecast.

Most trees are healthy and worth keeping. Shade cools your home, and mature trees add a lot to a property. The goal isn't to cut everything down. It's to catch the few trees that are quietly becoming a risk to your roof, your car, your neighbors, or the people walking under them.

Here are the warning signs to look for, and what to do if you find them.

1. Dead or hanging branches

Dead limbs are the most common hazard, and the easiest to spot. Look for branches with no leaves when the rest of the tree is full, bark that's peeling away, or wood that looks gray and brittle. Even more urgent are "hangers": broken branches that are caught in the canopy and could drop at any time, especially in wind.

A few small dead twigs are normal. Large dead limbs over a roof, driveway, pool deck, or sidewalk are not, and they're worth having removed soon.

2. Cracks and splits in the trunk

Deep vertical cracks in the trunk, or splits where two large stems meet, are a serious sign. Pay special attention to trees with two or more trunks growing from the same point in a tight "V" shape. Those joints are often weak, and in a strong wind one side can tear away from the other.

If a crack goes deep into the wood or seems to be getting longer, have the tree looked at by a professional rather than waiting.

3. A new or worsening lean

Plenty of trees grow with a slight lean and stay that way for decades. What matters is change. If a tree has started leaning recently, especially after a storm, or if the soil on the opposite side of the lean is cracked, lifted, or mounded up, the roots may be failing. That kind of lean can turn into a fall with very little warning.

4. Mushrooms, soft spots, and hollow areas

Fungi growing at the base of a tree or on the trunk often mean there's decay inside. So do soft or crumbly wood, large cavities, oozing sap, and sawdust-like material around the base. A tree can look green and healthy on top while the trunk or roots are rotting underneath.

Tapping the trunk and hearing a hollow sound is another clue. Decay doesn't always mean a tree has to come down, but it does mean someone qualified should check how much solid wood is left.

5. Root damage and soil problems

Roots are easy to forget because you can't see most of them. Watch for:

• Roots that were cut during driveway, sidewalk, pool, or irrigation work

• Soil that heaves or cracks around the base when the wind blows

• A lot of dead or missing roots on one side of the tree

• Constantly soggy ground around the base, which can weaken roots over time

South Florida's sandy soil and high water table mean many trees have fairly shallow root systems to begin with. Damage to those roots makes a tree much easier to topple in a storm.

6. Trees too close to your home or power lines

Some trees aren't sick at all. They're just in the wrong place. A large tree whose branches rub the roof, hang over the house, or tangle with power lines is a risk every time the wind picks up.

Large ficus trees are a common example here. They grow fast, get very big, and their roots can lift sidewalks, driveways, and pool decks. Regular trimming can keep many trees in check, but sometimes removing a tree that has outgrown its spot is the safer long-term choice.

One important note: never trim or remove anything near power lines yourself. Contact your utility first, since they handle work near their lines.

7. Leftover storm damage

If a past storm stripped branches, snapped the top of a tree, or tore bark off the trunk, the tree may still be weakened even if it looked fine afterward. Broken stubs can let decay in, and trees that lost a large part of their canopy can regrow weak, crowded branches that break more easily later.

If you still have damaged trees or debris left over from a storm, our storm cleanup service can clear it out and help you figure out which trees can be saved.

8. Palms with problems

Palms deserve their own mention because they're everywhere in South Florida. Warning signs include a trunk that's narrowing sharply near the top (sometimes called "pencil-pointing"), a crown that's drooping or collapsing, a spear leaf in the center that's dead or pulls out easily, and heavy seed pods or dead fronds that could fall.

Keep in mind that over-trimming makes palms weaker, not safer. UF/IFAS recommends removing only dead or fully brown fronds, not healthy green ones. Our tree and palm trimming page covers what proper palm pruning looks like.

Trim, treat, or remove?

Not every warning sign means a tree has to go. Often, removing dead wood, thinning a crowded canopy, or raising branches away from the roof is enough. Removal makes more sense when:

• Decay or cracking has damaged a large part of the trunk or main roots

• The tree is leaning more over time

• It's dead or mostly dead

• It's simply too big for where it's growing and keeps causing damage

If you're unsure, it's worth having a qualified professional look at it. For trees with serious structural questions, an ISA-certified arborist can give you a formal assessment.

Do you need a permit?

Many cities and counties in South Florida regulate tree removal, and some trees are protected. Florida law (Section 163.045, Florida Statutes) says a local government can't require a permit to remove a tree on residential property if an ISA-certified arborist or a Florida-licensed landscape architect documents that the tree poses a danger to people or property. Rules for commercial properties and for non-hazardous trees are different, and HOAs often have their own approval process, so check with your city and your association before work starts.

A note for HOA boards and property managers

Trees in common areas, along entrances, near walkways, and beside parking lots are the community's responsibility. A simple walk-through each fall, looking for the signs above, makes it much easier to plan and budget for tree work instead of reacting after something falls. If your community wants help keeping its grounds safe year-round, take a look at our HOA and community landscaping services.
