How to Tell If a Tree Is Dead

A tree is dead when the wood under its bark is dry and brown, it puts out no leaves or buds in the growing season, and its branches snap clean instead of bending. You can check most of this yourself in ten minutes. If the trunk or several big limbs fail these tests, it’s time to have the tree looked at.

The Scratch Test

Use a fingernail or a pocketknife to scrape a small patch of bark off a twig. Green, moist tissue underneath means that part is alive. Brown and dry means it’s dead. Test several branches on different sides of the tree, and one low on the trunk. A few dead twigs are normal. Dead tissue all the way around means the tree is gone.

The Bend Test

Bend a small branch. Living wood flexes. Dead wood snaps with a dry crack. Try this on branches you can reach from the ground, never on a ladder under a tree you suspect is dead.

Signs You Can See From the Ground

• No leaves in June. By early summer, every healthy tree in Vaughan has leafed out. Bare branches then are a bad sign.
• Bark falling off. Large patches of bark peeling away and exposing smooth, grey wood.
• Fungus at the base. Mushrooms, shelf fungi or soft, crumbly wood where the trunk meets the ground point to rot in the roots.
• Cracks in the trunk. Deep vertical splits, or a cavity you can push a hand into.
• Dead limbs in the top. Branches with no leaves up in the crown while the lower ones look fine. Trees often die from the top down.
• A new lean. A tree that has started leaning, with soil heaving up on one side, has root trouble.

Ash Trees and Emerald Ash Borer

Emerald ash borer has killed most untreated ash trees across the GTA, including the ones planted along streets in Maple and Vellore Village. Look for D-shaped exit holes about the size of a pencil, bark splitting to show S-shaped tunnels underneath, woodpecker damage, and a thinning crown with shoots sprouting low on the trunk. An ash that shows these signs is usually dying, and dead ash turns brittle fast.

Dead or Just Stressed?

A hard winter, a dry summer or construction near the roots can make a tree leaf out late or drop leaves early. That’s stress. A stressed tree still passes the scratch test on most branches. Give it a season, water it in dry spells, and look again. A tree that fails the scratch test on the trunk won’t come back.

Dead Branches on a Living Tree

A tree can carry a few dead limbs and still be healthy. Shaded lower branches die off naturally, and storms kill the odd limb. If the dead wood is a small share of the crown and the trunk passes the scratch test, the tree usually needs a trim, not a removal. We take the dead limbs out and tell you whether anything else needs watching.

Why Not to Wait

Dead wood dries out and loses strength each year. A dead tree that would come down in sections today can be too brittle to climb in two years, which makes the job slower and more expensive. Dead limbs also drop without warning, and on a lot with a driveway or a play area underneath that’s the bigger worry.

What Happens Next

If you think a tree is dead, call or text (289) 444-0864. We’ll come out the same day, check it with you and tell you plainly whether it’s dead, dying or worth saving. If it needs to come down, our dead tree removal takes it down in sections and cleans up after. Dead trees 20 cm or wider still need a City permit, but there’s no fee for it.
