Hey everyone, hope spring is bringing green grass to all. Unfortunately for me that green is poa triv. I have part of my lawn slow to green up from the winter and the poa triv is beating out the fescue. How should I tackle this. Should I spray tenacity to whiten up and then hit with Round up? I haven't mowed yet. In the area of my yard that gets a lot of sun it's growing fast however in the shadier areas it's slow to come up and that's where the poa is coming in strong. Will tenacity hurt fescue waking up from winter? Should I try to combat this triv asap or wait until May? I'm in Michigan zone 6b
