Check these first

  1. Check the water level in your container.
  2. Feel the soil to see if it is damp.
  3. Smell the water to ensure it is not stagnant.

Likely causes

  1. Dehydration

    Most likely

    How to tell: The leaves look limp and the soil surface feels dry to the touch.

    What to do: Add water to your container until the soil is submerged or thoroughly soaked. Keep the water level at least 1 inch above the soil line to ensure the roots stay hydrated.

  2. Root rot

    Possible

    How to tell: This is less common for this plant, as it thrives in water, but it can happen if the water becomes stagnant or foul. The base of the stems may turn mushy or discolored.

    What to do: Change the water in your container to refresh the oxygen levels. Trim away any black or slimy roots and ensure the plant has access to fresh, clean water.

When to worry

If the plant does not perk up within a few hours of adding water, the root system may be severely damaged. It is normal for the plant to look slightly tired if it has been moved to a new location.

Stopping it coming back

Always keep the soil submerged or consistently wet to prevent the plant from drying out.

Questions people ask

Can I let the soil dry out between waterings?
No, this plant requires constant moisture and will droop if the soil dries out even slightly.
Should I fertilize a drooping plant?
Avoid fertilizing until the plant has recovered. Adding nutrients to a stressed plant can cause further damage to the roots.
