Bermuda grass · Cynodon dactylon

Why is my Bermuda grass looking leggy?

Leggy growth happens when Bermuda grass reaches for more light. Check your surrounding trees or structures to see if they are casting too much shade.

Check these first

  1. Observe how many hours of direct sun the area gets.
  2. Check your mower height setting.
  3. Measure how long the grass has gone without a trim.

Likely causes

  1. Insufficient sunlight

    Most likely

    How to tell: The grass blades are thin, long, and sparse rather than thick and carpet like.

    What to do: Trim back overhanging tree branches to allow more direct sun. If the area is permanently shaded, consider planting a shade tolerant groundcover instead.

  2. Improper mowing height

    Possible

    How to tell: The grass grows tall and thin because it is not being cut frequently enough.

    What to do: Mow your lawn at least once a week during the growing season. Keep the height between 1 to 2 inches to encourage lateral growth.

When to worry

Worry if the grass becomes so thin that weeds start taking over. It is normal for the grass to grow faster and look slightly different during peak summer heat.

Stopping it coming back

Ensure the lawn receives at least 6 to 8 hours of direct sunlight daily.

Questions people ask

Can I fix leggy grass by fertilizing?
Fertilizer will not help if the issue is a lack of light. You must increase sun exposure for the grass to thicken up.
How short should I mow?
Bermuda grass prefers to be kept short, usually between 1 to 2 inches. Mowing at this height encourages the grass to spread horizontally.
