Why is my Western blue-eyed grass rotting at the base?

Root rot happens when your plant sits in soggy soil for too long, causing the roots to suffocate. Check the soil moisture levels first to see if your drainage is working properly.

Check these first

  1. Feel the soil an inch deep to see if it is wet.
  2. Check the bottom of the pot for standing water.
  3. Smell the soil for a sour or rotten odor.

Likely causes

  1. Overwatering

    Most likely

    How to tell: The base of the plant feels mushy and the leaves turn yellow or brown at the bottom.

    What to do: Stop watering immediately and let the top 2 inches of soil dry out completely. If the soil stays wet, repot the plant into a container with better drainage holes and fresh, well draining soil.

  2. Poor Drainage

    Possible

    How to tell: Water pools on the surface of the soil for a long time after watering.

    What to do: Mix in perlite or coarse sand to improve the soil structure. Ensure the pot has large holes at the bottom to allow excess water to escape.

When to worry

If the base of the plant is black and mushy, it is likely too late to save it. Some yellowing at the very base is normal as the plant ages.

Stopping it coming back

Only water when the top inch of soil is dry and always use a pot with drainage holes.

Questions people ask

Can I save a plant with root rot?
If you catch it early, you can trim away the mushy roots and repot in fresh soil. If the entire root system is black and slimy, it is best to start over.
How often should I water?
Water every 7 to 14 days depending on the heat. Always check the soil dryness before adding more water.
