I hope I'm not intruding with this post, but you guys are the pros and I don't think I can find better information from anyone else. I live just outside of Nashville, NC and I have a 2 year old home with a Fescue lawn (mix of K31 and Rebels III). I have been overrun with crabgrass for the last 2 years and I am considering converting my grass to a warm season variety. Considering that I have almost 2 acres of lawn, what would you do ? 1) Stick with the Fescue - overseed this fall with improved varieties, such as Rebels Exceda and the Confederate Blend. 2) Convert to a warm season grass, such as Centipede or Zoysia (if I choose this option I will kill the Fescue in the spring with RoundUp and seed with either Zenith Zoysia or TifBlair Centipede). I do not have an irrigation system, but I can water regularly during the germination period. I am leaning towards going with a conversion to Centipede or Zoysia, but I cannot decide between the two. I am concerned about the maintenance of the Zoysia but I also have concerns with the durability of the Centipede and being able to keep it green and not purple or red, so I am interested in hearing what you think is better between the two. Thanks for helping out.
