Dan,

My St. Augustine lawn was sodded 7 weeks ago. Can you tell what is going on and what I can do?

Thanks, Jerry

Thank you for the excellent photos. The one that is most helpful is the shot of the whole section of your yard. If you look carefully, you will see a pattern in the damage. Natural causes for lawn damage, such as insects or diseases, do not occur in patterns like this.

This kind of damage is caused when a fertilizer or weed killer is applied to the lawn. You can see the pattern that would result in someone pushing a drop spreader back and forth over the lawn applying something.

There is really nothing you can do when this happens. The grass may slowly recover – it looks like it has a good chance of doing so if it is stable at this point and not getting any worse.
