Willow Borer Suspected in Dead Weeping Willow

Diagnosing Root Rot and Insect Damage

A weeping willow died after two years of decline. Symptoms: root chunks pull off by hand, revealing rotten wood and tiny white larvae (1/32 inch). This matches poplar/willow borer (Cryptorhynchus lapathi) damage.

Next Steps

Consult a certified arborist or county extension agent before replanting.
Remove all infested wood and roots; do not compost.
Consider non-host trees for replacement.
