I had to pull the trigger and re-sod #4 lake green on Thursday morning. While there were still some green plants mixed in, some of the green plants were starting to turn yellow at the crown. The sod came from our nursery green and matches well with what is currently on the green. The upcoming rain showers over the weekend should help it root very fast. Don't worry about walking on it or putting over it as we took a deep cut of sod (2").
