Philodendron New Leaves Stuck in Sheaths: Causes and Fixes

Heart-leaf philodendron cuttings produce new leaves that trap themselves in their sheaths, snapping the stems. The owner's arrowhead philodendron in the same conditions is fine.

Hard Water Suspect

Mineral buildup from hard water often prevents leaves from unfurling properly. If your tap water is hard, switch to filtered or distilled water. Also, confirm the plant ID—heart-leaf philodendrons rarely have this issue. A photo would help diagnose.

Consistent moisture and proper humidity aid leaf expansion. Avoid letting cuttings dry out completely.
