Why is my Rajah pitcher plant showing signs of root rot?

Root rot happens when the soil stays soggy and lacks oxygen. Check the drainage of your pot immediately to ensure water is not pooling at the bottom.

Check these first

  1. Smell the soil for a sour or rotten odor.
  2. Check if the pot is sitting in a tray of standing water.
  3. Gently lift the plant to see if the roots are brown and mushy.

Likely causes

  1. Waterlogged Soil

    Most likely

    How to tell: The plant looks wilted despite the soil being wet. The base of the stem may turn black or mushy.

    What to do: Repot the plant into fresh, airy long fiber sphagnum moss. Ensure the pot has plenty of drainage holes and never let it sit in standing water.

  2. Dense Growing Medium

    Possible

    How to tell: The soil feels heavy and does not dry out for many days. The plant stops producing new pitchers.

    What to do: Mix in more perlite or orchid bark to improve aeration. Avoid packing the moss too tightly when repotting.
