Black Stems Crown Rot on pothos

pothos with black stems crown rot

What's Happening

Crown rot occurs when rot progresses from roots into the stem base where leaves emerge. This is a critical failure point—once crown tissue becomes compromised, the plant cannot produce new leaves and survival depends on healthy nodes above the damage. Anaerobic bacteria migrate upward through vascular tissue.

How to Fix It

  1. 1

    Inspect immediately: Check stem base where it meets soil—healthy tissue is firm and white/green

  2. 2

    If base is mushy: Cut stem 2-3 inches above rot line with sterile scissors

  3. 3

    Check cut tissue: Continue cutting upward in 1-inch increments until finding firm, healthy interior

  4. 4

    Each cutting must have 2-3 nodes with aerial roots for successful propagation

  5. 5

    Root cuttings in clean water with weekly changes; expect roots in 2-4 weeks

  6. 6

    Once rooted, plant 3-4 cuttings together in fresh soil for fuller recovery plant

How to Prevent It

Avoid pots that are too deep—shallow pots reduce moisture retention around stem base; ensure water drains completely; never let pot sit in standing water; provide good air circulation around plant base.
