Okay, so lemme tell you about my recent adventure trying to get my St. Augustine grass looking lush in Texas. Man, it’s been a journey!
First off, I started by doing some serious Googling. I mean, Texas weather is no joke, and St. Augustine is kinda picky. I saw tons of articles talking about nitrogen, phosphorus, and potassium – NPK, you know? Looked like nitrogen was the main thing for green growth. But I didn’t wanna just throw stuff down and hope for the best.

So, I went down to the local garden center – not the big box store, but the small, family-owned place. I talked to this old guy there, seemed like he knew his stuff. He asked me about my soil, if I’d ever tested it. I hadn’t. He recommended I get a soil test kit, which I promptly bought.
Next day, I dug up some soil samples from a few different spots in my yard. Followed the instructions on the kit, mixed everything up, and sent it off to the lab. Took about a week to get the results back. Turns out my soil was kinda low on nitrogen, just like I suspected, but also needed a bit of iron.
Armed with that knowledge, I headed back to the garden center. This time, I showed the old guy my soil test results. He suggested a fertilizer specifically for St. Augustine grass with a higher nitrogen content and some added iron. He pointed me towards a slow-release granular fertilizer. He said it would feed the grass over a longer period and prevent burning it, which is apparently a thing.
I grabbed a bag and carefully read the instructions. The bag told me how much to use per square foot. I measured out my lawn to figure out how much fertilizer I needed. This part was kinda tedious, I gotta admit.
Then came the fun part (not really). I rented a fertilizer spreader from the hardware store – one of those push-along ones. Loaded it up with the fertilizer, set the spreader to the recommended setting, and started walking back and forth across my lawn, overlapping each pass slightly. It took a couple of hours, but I got the whole yard covered.
After spreading the fertilizer, I watered the lawn thoroughly. This helps the fertilizer dissolve and get down to the roots. The old guy at the garden center stressed the importance of watering after fertilizing, so I made sure to do a good job.
I waited. And waited. And waited. It took about two weeks, but I started to see a noticeable difference. The grass turned a deeper green and looked much healthier. Some of the bare spots even started to fill in. I was pretty stoked.
Here’s the thing I learned though: it’s not a one-time deal. You gotta keep up with it. I plan to fertilize my St. Augustine grass a few times a year, following the recommendations on the fertilizer bag and keeping an eye on the overall health of the lawn.
So, to recap:
- Test your soil! It’s the key to knowing what your lawn actually needs.
- Talk to the experts at your local garden center. They usually have good advice specific to your area.
- Follow the instructions carefully! Don’t over-fertilize, or you could burn your grass.
- Water thoroughly after fertilizing.
- Be patient! It takes time to see results.
A Few Extra Tips
I also learned that you should try to time your fertilizer applications with the growing season. St. Augustine grass grows best in the spring and summer, so that’s when you should be fertilizing. And don’t fertilize when the grass is stressed, like during a drought.
Also, consider using an organic fertilizer. They’re generally more expensive, but they’re better for the environment and can improve the overall health of your soil. I might try that next time.
Anyways, that’s my story. Hope it helps someone else out there trying to keep their St. Augustine grass happy in Texas!
