Where do you live?

Including watering, what have you done to it this year?

When did it start to look dead?

Killeen, TX

Water twice a week.

So far put down a application of milorganite.

seems like my yard is slow to green up compared to my neighbors.

grass started to look dead in the fall when it went dormant

Current state of rest of front yard

The area right of the driveway water does seem to pool there, but it has been doing good until this year.

In the front by the tree ring there is no low spot.

I have stopped watering as of this past Sunday.

Great. Having stopped watering after watering relatively frequently, you have to keep a close eye on the grass. At the first sign of wilting (color change or blades folding up), then water deeply a full inch as described. The grass you have now does not have the deep roots that will develop with deep and infrequent watering. Develop those roots by gradually slipping into deep and infrequent. To show you the extreme of deep roots, I lived in George West (half way between San Antonio and Corpus Christi) for a few years. I let my St Augustine grow without mowing for several years. It got up to 32 inches tall and stopped growing. That very tall grass developed very deep roots. There were some places where I did not water at all for more than 30 months (can't remember those details). The roots were deep enough that even through a drought they grass remained alive. It did not always look excellent, but as soon as it rained, it looked excellent for many months to come.
