One more pic.
How about your location? City? Lots of different weeds look like that by region.
Thanks for the reply. We are from Dallas. We have Bermuda gross. Previous owner planted winter rye gross during winter. But, we only see Bermuda gross in our lawn now.
Compare your plant to Common Knotgrass, Polygonum aviculare.
Does this pic match?
If so, you don't have knotweed. That's be easy to control and no need to post.
