Propagation Rot on pothos

pothos with propagation rot

What's Happening

Pothos water propagation failure occurs when cuttings develop mushy stems or rot instead of healthy white roots, typically from bacterial contamination in stagnant water or using unhealthy parent material. The sugars released from cut stems feed bacteria that outcompete root primordia development, especially in warm conditions with infrequent water changes.

How to Fix It

  1. 1

    Inspect cutting daily—healthy stems remain firm, rotting stems turn translucent/mushy

  2. 2

    Trim 1/2 inch from cutting base if any mushiness appears, creating fresh wound

  3. 3

    Change water completely and clean container with mild soap before reinserting

  4. 4

    Move to slightly brighter indirect light to accelerate root development

  5. 5

    If rot persists on same cutting after 2 trims, discard and start fresh cutting from healthy mother plant

How to Prevent It

Take cuttings only from healthy vigorous stems with no signs of disease; change propagation water every 3-5 days to prevent bacterial buildup; use room temperature dechlorinated water (let tap water sit 24 hours); place in bright indirect light (not direct sun) to encourage rooting without algae growth; sterilize containers between uses.
