Mikest Posted February 7, 2016 Share Posted February 7, 2016 Can anyone tell me what this is growing in my St. Augustine lawn and how to get rid of it? I suspect it may be some type of grass, because weed and feed won't kill it. Link to comment Share on other sites More sharing options...
mollusk Posted February 7, 2016 Share Posted February 7, 2016 It looks like winter rye grass. Some people even plant it intentionally. If you don't like it, keep it mowed before it starts to seed (too late in the photo above). It will take a few years, but it'll eventually die out. In the meantime, it's not particularly harmful (thought wind blown seeds spread it into the bedding given half a chance). Link to comment Share on other sites More sharing options...
Mikest Posted February 7, 2016 Author Share Posted February 7, 2016 I had a feeling that's what it was. Maybe I will try and big up patches of it and put down St. Augustine sod to see if it will take over. Thank you for the reply. Link to comment Share on other sites More sharing options...
samagon Posted February 8, 2016 Share Posted February 8, 2016 ultimately, it shouldn't even need that, as the st augustine starts growing again, it will take over when the winter grass goes dormant. keeping the deck on your mower as high as you can will result in the st augustine having deeper roots and allow it to overpower pretty much anything when spring hits. if you keep the deck high enough on your mower, you should never need to put down new st augustine.

Fore Right Posted February 8, 2016 Share Posted February 8, 2016 It's called Poa Annua. It's a winter weed that will die off for the year when the weather warms up. You can try and keep It from germinating next fall by using a pre-emergent and preventing a repeat performance next winter. Link to comment Share on other sites More sharing options...
