TL;DR: To tell if a tree is dead, check for brittle bark, no summer leaves, fungus at the base, a new lean and dead branches up top. A dying tree usually shows two or more of these at once. If it’s leaning over your roof, don’t wait for confirmation from the next thunderstorm.
Most trees don’t keel over out of nowhere. They drop hints for a season or two before a branch lands on the patio furniture, and most of us stroll right past those hints on the way to the mailbox. July is a great month to actually stop and look. Every healthy tree in mid-Missouri should be wearing its full summer wardrobe right now, so a half-bare tree is a red flag.
5 Signs of a Dead or Dying Tree at a Glance
Before you head outside, here’s the short list. One of these is worth a closer look. Two or more on the same tree, and it has moved from “keep an eye on it” to “let’s talk”:
- Bark that is brittle, cracked or peeling away in sheets
- Bare branches or sparse foliage in the middle of summer
- Mushrooms or hard, shelf-like conks growing at the base
- A new or worsening lean, often with lifted soil or exposed roots
- A thinning crown with dead branches at the top
The sections below explain what each sign means, why it points to decline, and when to consider professional tree services.
1. Brittle or Peeling Bark
Healthy bark is firm and renews itself, kind of like skin. On a tree in decline, it turns brittle, cracks or sloughs off in sheets, leaving smooth dry wood underneath.
The fastest way to check is the scratch test, and it costs nothing but a fingernail:
- Scrape a small twig with your thumbnail.
- Green and a little moist underneath means it’s alive.
- Brown and dry means that part has called it quits.
Try it on a few branches around the tree, not just the one closest to the deck. If most of them come back brown, the problem is the whole tree, not one cranky limb. Big bare patches on the main trunk are a more serious flag, because they usually sit right over rot you can’t see.
2. No Leaves or New Growth in the Summer
In July, a happy tree is dressed head to toe. When part of it can’t move water and nutrients anymore, the leaves are the first to spill the secret.
Keep an eye out during the growing season for:
- Whole branches that stay bare while everything else fills in
- Leaves on only one side, like a bad haircut
- Foliage that’s smaller or paler than you remember from past summers
How Can I Tell if My Tree Is Dead or Just Dormant?
Dormancy happens in winter, not summer. If a tree has no leaves in July while neighboring trees are full, it is likely dead or severely declining. Confirm with the scratch test: living branches show green tissue just under the bark, while dead ones snap dry and brown.
3. Fungal Growth at the Base
Mushrooms and hard, shelf-like conks near the trunk are not the charming woodland touch they look like. Those fungi eat decaying wood, which means rot is already throwing a party inside the trunk or roots where you can’t see it. By the time they show up on the outside, they’ve usually been at it for a while.
Where they appear tells you a lot:
- At the soil line or on the roots: points to root rot, which weakens the tree’s grip on the ground.
- Higher up the trunk: suggests decay in the main stem and a real risk of the trunk giving way.
Should I Remove a Tree With Fungus at the Base?
Not always, but it warrants a professional look. Fungal conks at the base often signal internal root or trunk decay that weakens the tree from the inside. An expert can judge how far the rot has spread and whether the tree can stay standing safely.
4. Leaning or Structural Instability
A tree that suddenly leans is the one that should get your attention fastest. It usually means the roots have lost their grip, and our heavy mid-Missouri clay doesn’t help, since it holds water after storms and loosens everything up.
Check the base and trunk for:
- A lean that’s new or has gotten worse over the past few months
- Soil that’s cracked, heaved or mounded on one side
- Roots lifting up on the side opposite the lean
- Deep cracks running up the trunk
Is a Leaning Tree Dangerous?
A tree that has always leaned slightly may be fine. A new or worsening lean is a red flag, especially with cracked soil or raised roots at the base. That pattern signals root failure, and the tree can fall without further warning. Have it assessed promptly.
5. Canopy Thinning and Dead Branches
Tip your head back and look up. The crown usually shows decline before the trunk does, and the view overhead tells you how far along things are.
You’re looking for a crown that lets through more sky than it did last year, bare “stag-head” branches poking up above the green like antlers, and leafless limbs scattered through a tree that’s otherwise leafed out. Dead branches are a hazard all by themselves, since they tend to come down on their own schedule, usually the least convenient one. When the dieback starts at the top and works its way down, the tree is telling you how the story ends.
Stressed Tree vs. Dead Tree
There’s a real difference between a tree that’s having a rough year and a tree that’s done, and knowing which one you’ve got decides whether you reach for the hose or the phone.
A Stressed Tree
A stressed tree is struggling but still alive. Think scorched leaf edges, early fall color in August or one dead limb after a drought, a construction project or a brutal winter. With some attention and proper tree care, plenty of stressed trees bounce back just fine.
A Dead Tree
A dead tree comes up brown on the scratch test everywhere you try, drops bark across the trunk, and stays bare straight through summer. At that point there’s no nursing it back, and the conversation shifts to taking it down safely before it decides to come down on its own.
When a Tree Becomes a Safety Hazard
A tree becomes a hazard when its failure would land on something you’d rather it didn’t. Run through this quick checklist:
- Too close to structures: branches or the trunk leaning over your house, garage, driveway, or the power lines.
- Storm exposure: our spring storms, summer gusts and winter ice all lean on weak limbs until something snaps.
- Visible decay: hollow spots, big cavities or fungus paired with a lean.
- Where people gather: dead trees hanging over patios, sidewalks or the kids’ play area.
A dead tree near the house is a liability and a drag on your property value, and it doesn’t get safer with age. The longer it stands, the more brittle and unpredictable it gets.
Missouri Trees Prone to Decline
Some tree species are more prone to decline in Missouri, so knowing what’s in your yard helps you gauge the risk:
- Ash: Emerald ash borer has hit ash trees hard across mid-Missouri. An untreated ash with a thinning crown is often past the point of saving.
- Oak: Oaks can fall to oak wilt, which browns the leaves and can take a tree down fast in summer.
- Bradford (Callery) Pear: Pretty in spring, structurally fragile forever after. They love to split down the middle in a storm as they age.
If any of these are on your property, give them a closer look each season and act early when something seems off.
When to Call a Tree Removal Professional
Some of this you can size up from the back porch with a glass of iced tea. Other situations are worth a trained tree removal professional. Call a pro when:
- Two or more warning signs show up on the same tree
- There’s any new lean, especially with disturbed soil at the base
- Fungus shows up alongside a cavity or visible decay
- A dead tree is standing within falling distance of your home or your neighbor’s
