This will be the 3rd spring I have been in my house, which had new bluegrass sod when I moved in. I have overseeded the past 2 years with Fescue with good results. My problem is that for the last two years, my lawn has been the last one in the neighborhood to green up. Many of my neighbors have green grass by mid-March, while I am not up and running until mid-April. Any thoughts on why this is the case? Thanks for your input.
