Why Do Trees Drop Dead Branches?
A branch is dead well before it finally falls — the tree cuts off its water and nutrients first, and the wood spends a season or longer drying out and turning brittle before it actually lets go. That gap is exactly why dead branch removal matters: what could have come down as routine maintenance instead lands, unannounced, on a vehicle, a roofline or wherever someone happens to be walking.
Which Dead Branches Need Attention First?
Some situations are more urgent than others, and it helps to know which is which before you call:
- A cracked branch still hanging in the crown, waiting to finish falling - Anything dead positioned above a driveway, front walk, doorway or a car - Deadwood reaching out over a sidewalk or public road - A branch resting on or near a hydro line
Dead wood sitting over open lawn with nothing valuable underneath can usually sit on the dead branch removal schedule rather than jump the line, and we will tell you plainly when that applies.
How Can I Tell A Branch Is Actually Dead?
Four signs give it away without climbing a ladder, and spotting any single one is reason enough to call:
- One bare branch in the middle of July while the rest of the crown is green - Bark peeling back to expose grey, dry wood - Fungus growing directly out of the branch or the trunk base - Woodpecker holes on an ash, usually a sign of borers working underneath
Why Are Dead Branches Common On Ash Trees Here?
Emerald ash borer wiped out most of the mature ash across eastern Ontario over the past decade, and dead branch removal on an ash is a genuinely different job than the same work on a living tree. The wood dries out and turns brittle right through, and it tends to fail at the branch union rather than snapping cleanly along the limb, which changes how a climber has to plan every cut.
What Happens During A Dead Branch Removal Visit?
A dead branch removal visit starts with the whole tree, not just the limb that prompted the call, since dead wood tends to appear in more than one spot at roughly the same stage. Anything above a roof, driveway or fence comes down on rope rather than dropped, everything gets chipped and hauled off, and the site is raked clean before the crew packs up.
