Banana Plant Root Rot Diagnosis Requires More Information

Sandra in Yorktown, VA (Zone 8) has basjoo bananas in garage under grow lights since November. Leaves emerging partially brown/dry. Largest (7-8 ft) crushed by ceiling. Stem diameter 4", pot ~2 ft diameter. Leaf stems brown inside—asks if root rot spreads upward.

Insufficient Data for Diagnosis

Multiple possibilities:

• Cold garage temperatures
• Natural dormancy
• Inadequate light (how many lights? type? distance?)
• Root rot

"Partially brown dry leaves" alone cannot diagnose. Root rot doesn't spread up stems—dying roots can't supply water, causing leaf dieback.

Needed Information

Garage temperature, grow light details, watering routine, soil type. Without these, any diagnosis is irresponsible speculation.

Bananas are challenging indoors. Consider outdoor planting if zone permits.
