Heath Milkwort · Polygala serpyllifolia

Why is my Heath Milkwort suffering from root rot?

Root rot is a common issue for Heath Milkwort when the soil stays soggy for too long. Check the drainage holes in your pot first to ensure water is not pooling at the bottom.

Check these first

  1. Check if the pot has drainage holes.
  2. Smell the soil for a musty or rotten odor.
  3. Inspect the roots for a brown, mushy appearance.

Likely causes

  1. Overwatering

    Most likely

    How to tell: The stems look mushy near the base and the soil smells sour or swampy. You might see the plant wilting even though the soil is wet.

    What to do: Stop watering immediately and let the top 2 inches of soil dry out. If the plant is severely affected, repot it into fresh, well draining soil and trim away any black, slimy roots.

  2. Poor Drainage

    Possible

    How to tell: Water sits on the surface of the soil for a long time after watering. The pot lacks holes or the soil mix is too dense and heavy.

    What to do: Repot the plant into a container with adequate drainage holes. Use a mix that includes perlite or sand to improve aeration.

When to worry

If the base of the stem is soft and brown, the rot has likely spread too far to save the plant. It is time to take cuttings if any healthy stems remain.

Stopping it coming back

Always ensure the top inch of soil feels slightly dry before watering again, and never let the pot sit in a saucer of standing water.
