Wide blade, prominent veins, but no mid-vein--suggests tall fescue--probably old-fashioned K-31. It was a good pasture grass 50 years ago. The leaf blades have microscopic barbs or rough hooks along the edges. You can feel the roughness if you pass it along your lips.
This is a good reason to never buy really cheap seed. Probably included in a low-quality seed mix from years ago. Possibly present as a contaminant listed as "other crop".
Here to stay, I suspect. Chemical control--depends--I am not familiar with chemicals that can be used on southern grasses.
This depends on your location. What part of Texas?
Chiming in for a riggle question. Not slandering the suggestion of falcon IV, just curious why one rated like falcon IV compared to all the newer higher rated varieties? I truly mean I’m not questioning that decision, just wanting to learn. But it’s ratings in the various ntep tests don’t show it as a standout. It’s not poor either. Appears a middle of the pack kind of rating. I’m strictly trying to learn, so would you share?
Riggle*. Darn auto correct has messed his name up twice now. Later in the post should read, “he in no way...To clarify, Ruffle did not specifically suggest Falcon IV. I simply mentioned that this is what I had and that I would be mixing with a small amount of KBG. He UNC no way suggested the specific product, seems to be extremely knowledgeable, and I really appreciate his input!
