Likely causes
Underwatering
Most likelyHow to tell: The grass blades look thin and curled with dry, crispy tips. The soil feels hard and dry several inches down.
What to do: Water your lawn deeply once a week to encourage roots to grow down into the soil. Aim for 1 inch of water per week, applied in one session rather than frequent light sprinkles.
Dull Mower Blades
PossibleHow to tell: The tips of the grass blades look shredded or jagged rather than cleanly cut. This damage turns brown quickly after mowing.
What to do: Sharpen your mower blades at the start of every season. A clean cut prevents the grass from losing moisture through torn edges.

When to worry
It is normal for grass to show some browning during extreme summer heat. Worry if the entire lawn is turning brown and brittle despite regular watering.
Stopping it coming back
