Cavendish Banana Tree Slumping: Overwatering Causes Rot

A newly planted dwarf Cavendish banana in Austin, TX, is slumping with a stripped stem and sap, while a neighboring red banana thrives. Both are on daily drip irrigation.

Diagnosis: Overwatering

Bananas are 85% water but hate sitting in wet soil. Daily watering leads to root rot. The slumping, sap, and dead leaves are classic signs.

Correct Watering Practice

• Weekly deep watering is sufficient for established plants.
• If recently divided/transplanted: Water once, then wait until new leaves appear before watering again—roots need time to regrow.
• Container plants: Water thoroughly once a week.

Reduce irrigation immediately. The plant may recover if rot hasn't destroyed the root system.
