Answer a few quick questions and get a general risk read — plus what to do next.
No leaves in season while the rest of the tree leafs out normally — a classic early sign of decline.
Especially with soil lifting or cracking on the opposite side — that's the root system giving way, not just growth habit.
Mushroom-like growths on the trunk or exposed roots usually mean internal decay, not just surface mold.
A hollow "thock" when you knock on the trunk, or a visible cavity, can mean significant internal decay.
Vertical cracks or missing bark exposing bare wood — entry points for decay and pests.
Split branches, exposed wood, or a cracked main leader after a storm — even if the tree "looks fine" otherwise.
Small holes in a pattern, sawdust-like material at the base, or thinning canopy can signal a borer infestation.
Roots visibly circling the trunk at the base can slowly strangle the tree over years.
