black stems on Snake Plant
Quick answer
If your Snake Plant has black stems, the most likely cause is: Black stems on snake plant result from bacterial or fungal infection spreading through vascular tissue, often initiated by overwatering, mechanical wounds, or cold damage at the base. The blackness indicates necrotic tissue that cannot transport water to upper leaf sections, causing progressive die-back if untreated.
Start here:
- 1. Cut into black stem tissue with sterile knife — if interior is white and firm, the rot has not reached that point
- 2. Cut 1-2 inches below blackened tissue into healthy white tissue
