Check these first

  1. Feel the soil 2 inches deep to see if it is wet.
  2. Inspect the base of the stems for soft or discolored tissue.
  3. Check if the pot has functional drainage holes.

Likely causes

  1. Overwatering

    Most likely

    How to tell: The soil feels constantly soggy and the base of the stems looks dark or mushy.

    What to do: Stop watering immediately and allow the top 2 inches of soil to dry out. If the plant is in a container, ensure it has drainage holes and empty the saucer after watering.

  2. Poor Drainage

    Possible

    How to tell: Water pools on the surface for a long time after you water the plant.

    What to do: Amend the soil with perlite or coarse sand to improve aeration. If the plant is in the ground, consider transplanting it to a raised bed or a spot with better drainage.
