Why is my Deptford pink wilting at the base?

Crown rot is a serious issue for this plant when the soil stays damp for too long. Check the base of the stems to see if they are turning mushy or dark.

Check these first

  1. Feel the soil two inches down to check for moisture.
  2. Examine the base of the stems for soft or mushy tissue.
  3. Check if your pot has holes at the bottom.

Likely causes

  1. Overwatering

    Most likely

    How to tell: The soil feels constantly wet and the base of the plant looks soft or discolored. The plant may start to collapse at the soil line.

    What to do: Stop watering immediately and let the soil dry out completely. If the rot is advanced, you may need to dig up the plant and trim away any black, mushy roots before replanting in fresh, well draining soil.

  2. Poor drainage

    Possible

    How to tell: Water pools on the surface after you water, or the pot lacks adequate drainage holes. The plant stays wet for more than two weeks.

    What to do: Repot the plant into a container with plenty of drainage holes. Use a gritty, sandy soil mix to ensure water flows through quickly.

When to worry

If the base of the stem is black and mushy, the plant is likely beyond saving. Act as soon as you notice the soil staying wet for too long.

Stopping it coming back

Always let the soil dry out significantly between waterings, usually waiting 7 to 14 days depending on the weather.
