Trees display warning signals before dying, allowing early intervention. Below are seven critical signs that your tree may be in decline.
Sign 1: Dead Branches That Don't Bud in Spring
Living branches produce new growth seasonally; persistent bare branches indicate death. If more than 25–30% of the crown has dead wood, the tree may be in serious decline. A scratch test using thumbnail pressure reveals green tissue (alive) versus brown/dry tissue (dead).
Sign 2: Bark Peeling, Cracking, or Falling Off
Deteriorating bark signals internal decay, disease, or frost damage. Cankers represent fungal or bacterial infection.
Sign 3: Fungal Growth at Base or Trunk
Shelf fungi indicate advanced internal decay and compromise structural integrity.
Sign 4: Unusual Lean
Changes in tree angle suggest root failure or decay, especially when accompanied by soil cracking.
Sign 5: Unusual Leaf Drop or Discoloration
Yellow, brown, or premature dropping indicates stress; patterns vary by cause.
Sign 6: Epicormic Shoots and Watersprouts
Stress-response growth signals potential crown loss.
Sign 7: Pest Activity
D-shaped holes indicate Emerald Ash Borer; similar signs appear with Bronze Birch Borer.
Early detection determines treatment success. If you're seeing any of these warning signs, it's time to have your trees evaluated by a trained professional.
