How do I fix root rot in my bunchberry?

Root rot is a serious issue for bunchberry that happens when the roots are deprived of oxygen due to waterlogged soil. Check the drainage of your planting site first to ensure water is not trapped.

Check these first

  1. Smell the soil for a sour or rotten odor.
  2. Check if the soil feels like a swamp.
  3. Gently pull at the base to see if the plant is loose in the ground.

Likely causes

  1. Poor Drainage

    Possible

    How to tell: The plant stops growing, leaves turn yellow or brown, and the base of the stem feels soft or mushy. The soil stays wet for days after watering.

    What to do: If the plant is in a container, repot it into fresh, well draining soil and trim away any black, slimy roots. If it is in the ground, amend the soil with compost to improve drainage.

  2. Overwatering

    Possible

    How to tell: The soil remains saturated and the plant shows signs of decline despite being watered frequently. The roots may emit a foul odor.

    What to do: Reduce your watering frequency to every 5 to 7 days. Allow the top inch of soil to dry out slightly before adding more water.
