Maidenhair spleenwort · Asplenium trichomanes

Why does my Maidenhair spleenwort have root rot?

Root rot happens when the soil stays soggy for too long, preventing the roots from breathing. Check the drainage holes of your pot immediately to see if water is trapped inside.

Check these first

  1. Smell the soil for a musty or rotten odor.
  2. Tip the plant out of its pot to inspect the root color.
  3. Ensure the pot is not sitting in a saucer of standing water.

Likely causes

  1. Overwatering

    Most likely

    How to tell: The fronds turn yellow and mushy, and the soil smells sour or swampy. The base of the plant may feel soft to the touch.

    What to do: Remove the plant from its pot and trim away any black, slimy roots. Repot into fresh, well-draining soil and ensure the pot has drainage holes.

  2. Poor Drainage

    Most likely

    How to tell: Water sits on the surface of the soil for a long time after watering. The plant looks wilted even when the soil is wet.

    What to do: Use a pot with plenty of drainage holes at the bottom. Mix your potting soil with perlite to improve aeration and water flow.
