Here's what has happened with my lawn thus far - New house, Tif 419 Bermuda sod installed around March 2017.
In 2018 we have-
Feb - 2-4d amine applied to dormant grass
Mar 31 -scalped
Apr 15- small app Milorganite
May 6- another small app Milorganite
May 7- applied Dithiopyr
Water with inground slrinklers about 2x per week, have been keeping the grass cut at 1 1/4"
My lawn was looking terrific ! Greening up wonderfully and then this week I've noticed brown and dying grass in my yard! What have I done to it? The grass was still brown in spots from the winter but new grass was spreading and starting to fill in nicely. Could the dithiopyr have killed some of my Bermuda ? I'm worried ! I thought I had a handle on this lawn and now I'm afraid I've done something horribly wrong !
