Hello, I am new here and need a bit a help. I have 4 lawns of centipede, one was killed a few years ago and seeded with Zenith Zoysia (not by me and not done very well). The 3 pure Centipede lawns were all sodded within the past couple of years. I am in SE NC and the soil temps are already getting to 55 degrees so I hope I am not too late in applying the pre-emergent, crabgrass is one of the main reasons to apply. I am realistically new to this so I cannot easily tell the difference between the Centipede and Zenith Zoysia. If the Zoysia is doing well, they would like to have it encouraged more than the Centipede, if not, the Centipede is fine. They just want one strong, preferably the Centipede. I need help with suggestions for pre-emergent for these lawns. Thanks in advance!
