Why is my liverwort rotting?

While liverworts love water, they need airflow to prevent the growth of harmful bacteria and fungi. Rot usually occurs when the plant sits in stagnant, swampy water for too long. Check the drainage of your container first.

Check these first

  1. Smell the soil for a foul odor.
  2. Check if the container has drainage holes.
  3. Look for slimy or black patches on the plant.

Likely causes

  1. Poor Drainage

    Most likely

    How to tell: The plant turns mushy, black, or slimy. There may be a foul odor coming from the soil.

    What to do: Ensure your container has drainage holes. If it does not, repot the plant into a container that allows excess water to escape.

  2. Lack of Airflow

    Possible

    How to tell: A fuzzy mold appears on the surface of the plant or soil. The plant looks waterlogged and limp.

    What to do: Increase ventilation around the plant. If it is in a closed terrarium, open the lid for a few hours each day.

When to worry

If the entire colony is slimy and smells bad, it is likely too late to save. Small patches of rot can be removed to save the rest of the plant.

Stopping it coming back

Use a well draining substrate and ensure there is a gentle movement of air around the plant.
