Wrinkled Leaves on Mature Banana Palms: A Puzzling Symptom

Unusual Presentation

"Wrinkled" leaves are not a typical banana disorder. Normal aging causes lower leaves to yellow/brown, not wrinkle.

Possible Causes

• Mechanical damage during emergence (wind, hail).
• Nutrient imbalance (boron deficiency causes distorted growth).
• Herbicide drift or chemical exposure.
• Corm/root damage from pests or digging.

Diagnostic Steps

1. Describe wrinkling: longitudinal ridges, crinkled margins, or puckered surface?
2. Check newest emerging leaf for similar symptoms.
3. Inspect corm and roots for damage.
4. Review recent chemical applications nearby.

Without more detail, a precise diagnosis isn't possible. Photos would help.
