pothos with black stems

What's Happening

Black lines on newly repotted pothos stems are normal post-transplant desiccation and crisping of thinner vascular or lenticel areas from handling stress. Distinct from bacterial soft rot which shows mushy spreading ooze.

How to Fix It

    4. Monitor weekly for new growth as recovery sign

  5. 5

How to Prevent It

Pre-water soil before repotting. Use airy aroid mix. Maintain consistent moisture post-transplant without overwatering.
