Your grass is going to be in growth and recovery mode for the next months. Come November it will start slowing down and then in mid to late December it will turn greyish -brownish as it goes dormant, saving energy for winter. It’s still alive, just “resting”. Timing will depend on cold snaps. But remember that it doesn’t get consistently cold until late December or January. (my wife and I were married outside in dripping springs on Dec 23rd…A bit risky but it worked out…)
