Signs Your Tree Is Dying (or Already Dead)

A dying tree usually shows a thin or bare canopy, dead branches that snap easily, bark falling off, fungus at the base, and new cracks or a sudden lean. If a quick scratch test shows dry, brown wood under the bark instead of moist green tissue, that part of the tree is dead. A fully dead tree near your home should be removed before wind or snow brings it down.

Trees don’t die overnight. Most give you months, or even years, of warning. The trick is knowing what to look for. Here are the clearest signs your tree is dying, how to check it yourself in five minutes, and when a dead tree turns from an eyesore into a real danger.

9 Signs Your Tree Is Dying

1. Bare or Thin Leaves in Spring and Summer

The easiest sign of a dying tree is a canopy that leafs out late, stays thin, or has bare sections while nearby trees are full and green. If the top of the tree is bare first, the tree is often declining from the crown down.

2. Brittle, Dead Branches

Healthy twigs bend. Dead twigs snap with a dry crack. If you find more and more dead branches every year, or large dead limbs hanging in the canopy, the tree is losing its fight.

3. Bark Peeling or Falling Off

Loose bark, bare patches on the trunk, or bark that falls off in sheets often means the wood underneath is dead. On a healthy tree, bark stays tight.

4. Fungus, Mushrooms, or Soft Wood

Mushrooms or shelf-like fungus growing on the trunk or roots are a sign of internal rot. So is wood that feels soft or crumbles when you press on it. Rot weakens a tree long before it falls.

5. Cracks and Splits in the Trunk

Deep vertical cracks, splits where two trunks meet, or cavities you can see into all reduce a tree’s strength. These are classic warning signs of a hazardous tree.

6. A New or Growing Lean

Some trees grow with a natural lean. A tree that suddenly starts leaning, especially with raised soil or cracked ground on the opposite side, may have failing roots.

7. Root Damage

Construction, trenching, a new driveway, or a patio poured over the roots can kill a tree slowly. Damaged roots often show up as a thinning canopy two or three years later.

8. Pests and Small Holes

Tiny holes, sawdust at the base, or heavy woodpecker activity mean insects are feeding inside. In the Denver area, small D-shaped holes and heavy woodpecker damage on ash trees are a common sign of emerald ash borer.

9. Leaves That Turn Early or Stay on Dead Branches

Leaves that brown out in midsummer, turn color weeks early, or cling to branches all winter long can all point to a dying tree.

Is This Tree Dead? Try the Scratch Test

If you’re not sure whether a tree is dead or just stressed, try this simple test:

1. Pick a small twig or branch.
2. Use your fingernail or a pocket knife to scrape off a tiny strip of bark.
3. Green and moist underneath means that part of the tree is alive.
4. Brown, dry, and brittle means that part is dead.

Test several branches in different parts of the tree. If most of them are brown and dry, the tree is likely dead or close to it. One dead branch doesn’t mean the whole tree is dead, but many dead branches across the crown usually do.

Dying Tree vs. Dead Tree: What’s the Difference?

A dying tree still has some living tissue. Parts of the canopy may leaf out, but the tree is declining year after year. A dead tree has no living tissue left. It won’t leaf out, the wood is drying out, and it’s getting weaker every season.

Both can be dangerous, but a fully dead tree is the bigger risk because:

• Dead wood dries out and turns brittle.
• Branches can drop without wind or warning.
• Roots rot, so the whole tree can tip over.
• It’s harder and riskier for a crew to climb, which can raise the cost the longer you wait.

Why Trees Die in the Denver Area

Denver’s climate is tough on trees. The most common causes are:

• Emerald ash borer: this invasive beetle is killing ash trees across the Front Range. Infested ash trees die within a few years and turn brittle fast.
• Drought: dry summers and winters stress spruce, pine, birch, and many shade trees.
• Storm damage: heavy spring snow and strong winds split trunks and break tops.
• Root damage: construction and compacted soil cut off water and nutrients.
• Old age: fast-growing cottonwoods, silver maples, and Siberian elms decline as they age.

When Should You Remove a Dying or Dead Tree?

Not every dying tree needs to come down today. But you should call a pro soon if:

• The tree is dead or more than half the canopy is bare.
• It’s leaning toward your house, driveway, fence, or a play area.
• Large dead limbs hang over places where people walk or park.
• You see fungus at the base, deep cracks, or a cavity in the trunk.
• It’s a dead ash tree, since dead ash breaks apart quickly.

A licensed crew can safely take down a dead tree in sections and haul everything away. Learn more about dead tree removal in Denver, or see our guide to hazardous tree removal for leaning and cracked trees. For very tall trees, read about large tree removal.

If a dead tree has already come down on your home, read what to do if a tree fell on your house, then call for emergency tree removal.

How Much Does It Cost to Remove a Dead Tree?

In the Denver area, removing a dead tree usually costs about $400 to $1,500. Small trees can cost less. Very large dead trees, trees over a house, or jobs that need a crane can cost $2,000 or more. Waiting often makes the job more expensive, because brittle wood can’t be climbed safely.

If you want the stump gone too, ask about stump grinding in the same visit. These are ranges only; a free estimate gives you an exact price.
