Trees rarely get sick overnight. Disease usually announces itself in small, readable ways first: leaves that spot and drop in July, a patch of bark that sinks and darkens, mushrooms appearing at the base of the trunk after rain.

Finding strips of bark under your tree is unsettling, but a tree losing bark is not always a tree in trouble.

When an ice storm moves through Evansville, the damage is usually done quietly overnight. Ice builds on every twig and branch, and a mature tree can end up carrying thousands of extra pounds it was never built to hold.
