Hello
You can start fertilizing lawns as soon as you've had to mow it 2-3 times. This ensures it is actively growing before applying. This timeframe in Harris County is late March- April, depending on your lawn. Fertilizer can again be applied in fall (Sep/Oct).
Just be sure not to fertilize when lawn is under stress. This includes after a freeze or during/directly after drought. Some believe they can add it to stressed lawn to fix the situation. That only adds more stress.
Here is the St. Augustine maintenance calendar, if that is the type of turf you have.
