Welcome to TLF. Glad you found us. I wish we could have gotten to you prior to starting the renovation, and we would have advised you not to till prior to renovating, but that's water under the bridge. Not sure why SSS would have sold you Yukon, as that's a pretty cold hardy seed, and from my memory, your location doesn't have many cold nights during the winter.Dazdnaz said:
I'm willing to take a stab at weed identification, and say that your non-bermuda-looking weeds are 1. nutsedge (most likely), 2. crabgrass and the next picture would be prostrate spurge.
If you haven't, visit the Warm Season popular topics noting the Bermuda Triangle with respect to weed control and Bermuda Bible: The New Testament for guidelines on how to maintain your new lawn.
