Sudden Summer Thunderstorms Are Testing Weak Branch Unions Across the Treasure Valley

Post Copy

Late summer in the Treasure Valley brings fast-moving thunderstorms with gusty winds, and those winds find every weak spot in a tree's structure. Branches with narrow, V-shaped unions are the first to fail, often with little warning.

A branch union that includes bark instead of solid wood grain is weaker than it looks from the ground. Add a gust of wind and the extra weight of summer foliage, and that union can split or drop the limb entirely.

A pre-storm inspection catches these weak unions before a storm makes the decision for you. Our crew looks specifically for included bark, co-dominant stems, and any limb that's grown too heavy for its attachment point.

Have you had a limb come down unexpectedly during a storm this summer, or noticed a branch that seems to sway more than the rest of the tree?
