There is a chemical for st Augustine you can use that slows the growth. Yard dude puts it down so I'm not sure of the name. Catch is, ya gotta keep your yard watered and fertilized properly because if it starts to die because of a lack of water or fert....your yard is fricked for the year because if the slow growth.

re: How do I make my grass grow slower?Posted by Hammertime on 5/14/12 at 3:43 pm to TH03
Honestly the only place it doesn't grow is where I piss and where my dog pisses. Last year I had a bunch in bonfires in one spot and it is already full of grass. It will swallow a beer bottle in a couple of months. I can't cut it lower or it will brown over and die. I am just looking for some chemicals or something to slowthe stuff down.
As far as the thatch goes, wouldn't de-thatching make it grow faster?
Now for St Aug I would just try a small spot and see how it does. St Aug has stolons, or horizontal growing stems on top of the ground. If you verti-cut too aggressive it could do some damage and make for a long recovery. I've never verti-cut st aug but it does wonders on bermuda.
Also you could try scalping it down once(cut at an extremely low height). Maybe worth a shot. And I would never fertilize St Aug with very much Nitrogen............ever.
And those rake looking things you drag with a mower are crap. They may work if you pass over your yard 100 times with it.
