Tulip Tree Bark Shedding: Root Stress, Not Disease

Tulip trees in Indiana lose bark on limbs annually, from tip to trunk; limbs eventually fall. No infectious disease known to cause this. Expert attributes it to root stress—hot, dry conditions. Water deeply during drought, fertilize per soil test, and protect trunk from mowers/string trimmers. Monitor spring leaf-out; thinning canopy may indicate internal decay, eventually requiring removal.

Management

• Deep watering in dry periods.
• Soil-test-based fertilization.
• Mechanical damage prevention.
• Annual spring canopy assessment.

Stress reduction is the only “treatment.”
