The house behind me had St. Augustine creeping into my Zoisia. I tried the first couple of years to pull out the St. Augustine shoots. I gave up. St. Augustine wins by a large margin. Most of my lawn is now St. Augustine in the back and the sides of my property but it is creeping to the front. I give it another couple of years and my entire lawn will be St. Augustine.
I'm used to St. Augustine grass from living in South Florida for 24 years. Then went back up north to that lovely thin bladed grass that was so soft on your bare feet. Now we have the "killer" grass again with those really wide blades. I do like that St. Augustine is dark green in color. I have to admit though, I also like St. Augustine grass because the shoots grow above the ground. Zoisia tunnels underneath and gets into flowerbeds and also pops up in the middle of shrubs.
