Red fescue · Festuca rubra

Why are my Red fescue grass tips turning brown?

Brown tips on your Red fescue usually mean the grass is struggling to get enough moisture during hot or dry spells. Check your soil moisture levels first to see if the roots are drying out too quickly.

Check these first

  1. Check the soil moisture with a probe or your finger.
  2. Inspect your irrigation system for clogged nozzles.
  3. Measure the amount of water your lawn receives each week.

Likely causes

  1. Underwatering

    Most likely

    How to tell: The soil feels dry and crumbly several inches down, and the grass looks dull or grayish.

    What to do: Increase your watering to 1 to 2 times per week. Make sure to soak the soil deeply to reach the root zone, rather than just sprinkling the surface.

  2. Heat Stress

    Possible

    How to tell: Brown tips appear during peak summer heat even if you are watering regularly.

    What to do: Apply a light layer of mulch or compost to help retain soil moisture. Avoid mowing during the hottest part of the day to reduce stress on the blades.

When to worry

It is normal for some browning during extreme summer heat, but if the entire lawn turns brown, the grass may be entering dormancy or dying.

Stopping it coming back

Water deeply and consistently to encourage deep roots that can better withstand dry periods.

Questions people ask

Should I cut off the brown tips?
You can trim them if you prefer, but it is not strictly necessary for the health of the grass. Ensure your mower blades are sharp to avoid tearing the grass.
Will the brown tips turn green again?
No, the brown parts are dead tissue and will not turn green. New growth will emerge from the base as long as the plant is healthy.
