Yucca Root Rot Diagnosis and Recovery Attempts

Classic Root Rot Symptoms

Spongy stem base, yellowing leaves, no new growth, fungal smell—all indicate advanced root/crown rot from past waterlogging. The repotting into ceramic with dry mix and drainage was correct, but the infection was already systemic.

Last-Ditch Efforts

• Stop watering completely until soil is bone-dry.
• Remove all dead/mushy tissue (sterile tools).
• Dust wounds with cinnamon or sulfur (natural fungicides).
• Provide maximum air circulation (fan).
• Bright light, warm temperatures.

Realistic Outlook

• If any green tissue remains, recovery is possible but slow (months).
• Yuccas are resilient—some regenerate from basal buds after complete top death.
• Consider propagating healthy top sections as cuttings (let callus, root in sand).
• Seek second opinion at AllExperts Houseplants forum.

Prevention: Yuccas need minimal water—only when soil is dry 2+ inches deep.
