Why are my Holcus mollis leaves turning yellow?

Yellowing on creeping soft grass is less common and usually points to issues with soil moisture or nutrient balance. Check the soil moisture levels first to see if the roots are struggling.

Check these first

  1. Touch the soil to see if it is waterlogged.
  2. Inspect the drainage holes for blockages.
  3. Check the leaf undersides for signs of pests.

Likely causes

  1. Overwatering

    Most likely

    How to tell: The soil feels soggy or swampy to the touch and the base of the grass may look mushy.

    What to do: Stop watering immediately and let the top 2 inches of soil dry out. Ensure your pot has drainage holes so excess water can escape freely.

  2. Nutrient Deficiency

    Possible

    How to tell: The leaves turn a pale yellow or lime green color while the plant growth slows down significantly.

    What to do: Apply a balanced liquid fertilizer diluted to half strength once every 4 to 6 weeks during the growing season. Avoid overfeeding as this can burn the delicate roots.

When to worry

Worry if the yellowing spreads rapidly across the entire clump. It is normal for the oldest, lowest leaves to yellow and die back as the plant matures.

Stopping it coming back

Maintain a consistent watering schedule and keep the soil moist but never saturated.
