    I don't see the new growth yellowing just the last years stuff, am I wrong

    If I am not mistaken you guys have literally just gotten out of winter, it has been a long winter there. What I see is the blades that have been burned by winter an haven't gotten going yet by warm soil temps

    Wait 2 weeks and post the same picture, no brown tips I'll bet

    the worms will love them

    Are you saying that you think the CGM burned your grass?? That pic doesn't look like a fert burn to me.

    we see "modeling" in the blades. almost like when it freezes here?? or a mold/ fungus issue, but that's rare with CMG. usualy CMG lawns dont get fungus.

    This is not winter brown, this is a bright yellow on the top 50%-100% of maybe every 20th blade.
    Here is a pic of some of the brown grass in the lawn. I don't have a side by side but the color difference is night and day.


    Now that I look at the original pic again you can clearly see the difference between the brown grass and the yellow grass.

    This pic is of a seperate issue in this lawn, infestation of a warm season grass. I pulled up the grass hoping that would be enough for an ID I did'nt dig up the root sry.
    It has been very wet this spring here.
    Lawn fungus causes what the yellowing or dormant grass?

    yellowing, it also causes a modeled or patchy, splotchy color in the blades. we think we seen it in the first pic. the flat blade that's from top right to center. it looks "modeled"?

    did it get any tea???
