Yucca Cane Stunted After Neglect and Overpotting

A Yucca cane grew well initially, then was left with a friend who didn't water it and kept it in a kitchen. On return, stems were dry, yellow leaves removed. Fortified soil added. Now growth is stuck; small new growth appears but doesn't develop. Plant near window but above radiator in North Dakota winter.

Diagnosis

Months without water/light severely damaged roots. Added soil hinders drying. Pot may be too large.

Recovery Plan

• Remove any soil added on top.
• If repotted to larger pot, revert to original pot.
• Keep as close to sunniest window as possible; radiator heat is fine if not touching plant.
• Allow top 3 inches of soil to dry before watering.
• Do not fertilize, repot, or disturb roots.
• "Stuck" growth likely won't recover; remove if it dries completely. If bark becomes loose/papery, that cane is dead.
• Be patient; recovery takes a long time.
