Trees highest risk for freeze-thaw damage in Michigan:
Silver Maple – #1 offender. Weak wood, naturally develops tight crotches that trap water, grows fast so structure is compromised. These fail constantly in freeze-thaw cycles.
Bradford/Callery Pear – Notorious for tight branch unions, holds water perfectly in crotches, weak wood. Often planted in subdivisions throughout Genesee County.
Willow species – Brittle wood, loves water so crotches stay wet longer, freezes cause catastrophic failures.
Box Elder – Weak wood, irregular growth patterns create water-collecting pockets, common weed tree around Michigan.
Siberian Elm – Brittle, fast-growing, terrible structure, holds water in branch unions.
Trees with existing damage – Any species with previous storm damage, cavities, or visible cracks becomes high-risk regardless of type.
Lower risk but still vulnerable: Older oaks with decay – Strong wood normally, but if they have rot pockets or cavities, water collects and freeze damage accelerates decay
Multi-trunk trees of any species – The union where trunks meet is a natural water collector
