When to worry
Worry if the browning moves down the entire blade. It is normal for tips to brown slightly during the peak of summer.
Stopping it coming back
Water deeply and infrequently to encourage deep root growth, which helps the plant withstand heat.

Questions people ask
- Does this mean my grass is dying?

- Should I fertilize to fix the brown tips?
- No, do not fertilize a stressed plant. Wait until it is well hydrated and showing signs of new growth first.
