Why is my Starry false lily of the valley rotting?

Root rot is less common for this plant, as it prefers moist soil, but it usually happens when the soil stays soggy for too long. Check the drainage holes in your pot first to see if water is pooling at the bottom.

Check these first

  1. Check if the pot has drainage holes at the bottom.
  2. Feel the soil two inches deep to see if it is waterlogged.
  3. Smell the soil for any signs of decay or rot.

Likely causes

  1. Poor drainage

    Most likely

    How to tell: The soil feels constantly swampy and the base of the stems may look mushy or dark. You might also notice a sour or swampy smell coming from the pot.

    What to do: Repot the plant into a container with plenty of drainage holes using a fresh, well draining potting mix. Trim away any black or slimy roots with clean scissors before replanting. Water only when the top inch of soil feels dry to the touch.

  2. Overwatering

    Possible

    How to tell: The foliage starts to yellow and wilt even though the soil is wet. The plant stops growing and looks generally unhappy.

    What to do: Adjust your watering schedule to every 5 to 10 days depending on how fast the soil dries out. Always check the soil moisture with your finger before adding more water. Ensure the plant is not sitting in a saucer full of standing water.

When to worry

If the stems are turning black and collapsing, the rot has likely spread too far to save the plant. It is normal for the plant to look slightly soft if it has just been watered.

Stopping it coming back

Use a porous potting mix and never let the plant sit in a tray of water for more than an hour.
