Not every tree that looks rough needs to come down — but some warning signs shouldn't be ignored. Here's what to watch for on your property.
1. Dead or Dying Branches in the Crown
If more than 25% of a tree's canopy is dead, the tree is under serious stress. Dead branches become brittle and can fall without warning, especially during Rochester's ice storms and high winds. A few dead limbs might be addressed with pruning, but widespread dieback usually means the tree is declining.
2. Large Cracks or Splits in the Trunk
Deep vertical cracks, seams that extend through the trunk, or splits at major branch unions are structural failures. These weaken the tree's ability to support its own weight. If you can see daylight through a crack in the trunk, the tree is compromised and should be evaluated by a professional.
3. Significant Lean That Wasn't There Before
Trees that have always grown at an angle are usually fine — they've adapted their structure over time. But a tree that suddenly starts leaning, especially after a storm or heavy rain, may have root failure. Look for heaving soil on the side opposite the lean. This is one of the most dangerous situations because it can mean the entire root plate is lifting.
4. Fungal Growth at the Base
Mushrooms growing at the base of a tree or on exposed roots are a sign of internal decay. The fungus is feeding on dead wood inside the trunk or root system. By the time you see mushrooms on the outside, the internal damage can be extensive. This is especially common in older maples and oaks in the Rochester area.
5. Root Damage from Construction or Grading
If you've recently had work done near a tree — driveway paving, foundation work, utility trenching — the root system may have been severed or compacted. Trees don't show damage from root loss immediately. It can take 2–5 years for symptoms to appear. If a tree near recent construction starts losing leaves early or producing smaller leaves, that's a red flag.
