Why is my Saxifrage rotting at the base?

Crown rot is a common issue for Saxifrage when the base of the plant stays too wet for too long. Check the soil moisture and the firmness of the plant base immediately.

Check these first

  1. Press the soil surface to see if it feels soggy.
  2. Check the drainage holes for blockages.
  3. Gently pull the plant to see if it is loose in the soil.

Likely causes

  1. Poor drainage

    Most likely

    How to tell: The soil stays soggy long after watering and the base of the plant feels mushy or smells bad.

    What to do: Repot the plant into a container with drainage holes using a well draining potting mix. Add perlite or grit to the soil to improve aeration.

  2. Overwatering

    Most likely

    How to tell: The leaves turn yellow and the crown begins to collapse despite regular watering.

    What to do: Wait until the top inch of soil is dry before watering again. Adjust your schedule to every 5 to 10 days depending on your home environment.

When to worry

If the center of the plant is black and mushy, it is likely too late to save the crown. It is normal for a few lower leaves to die back as the plant grows.

Stopping it coming back

Always water at the soil level rather than over the leaves to keep the crown dry. Use a gritty, fast draining soil mix.
