Cheatgrass · Bromus tectorum

Why are my cheatgrass leaves turning yellow?

Cheatgrass is a tough survivor, so yellowing leaves often signal that it is getting too much water or not enough sun. Check your soil moisture first, as this plant hates sitting in soggy ground.

Check these first

  1. Feel the soil to see if it is wet.
  2. Observe how many hours of direct sun the plant gets.
  3. Check for signs of standing water near the roots.

Likely causes

  1. Overwatering

    Most likely

    How to tell: The soil feels constantly damp or muddy to the touch. You might notice the yellowing starting at the base of the plant.

    What to do: Stop watering immediately and let the soil dry out completely. Ensure the soil has excellent drainage and avoid adding supplemental water unless the drought is extreme.

  2. Low Light

    Possible

    How to tell: The plant looks pale and weak, and it is growing in a shaded area. Cheatgrass requires full, direct sun to thrive.

    What to do: Move the plant to a spot that receives at least 6 to 8 hours of direct sunlight daily. If it is in a shaded corner, it will continue to struggle.

When to worry

If the entire plant turns yellow and wilts, it is likely suffering from root rot due to excess moisture. It is normal for the oldest bottom leaves to yellow as the plant matures and prepares to set seed.

Stopping it coming back

Only water during severe, prolonged droughts and ensure the plant is in a location with full sun exposure.

Questions people ask

Should I fertilize my yellowing cheatgrass?
No, do not fertilize. Cheatgrass is adapted to low nutrient soils and adding fertilizer will likely stress it further.
Will the yellow leaves turn green again?
Usually, no. Once a leaf has turned yellow, it will likely stay that way or die off, so focus on keeping the new growth healthy.
