Nice photo, Wilson! Amazing! Did someone plant the hybrid Bermuda in an unusual pattern? LOL! Impossible of course.
It must be a biological cause. Do you notice that the green parts are all about 3 inches wide--not more nor less. And the brown parts are about 6 inches wide seldom, more nor less.
What is underground? Tiger stripe soil? LOL! Or...deeper roots and shallow roots.
Why does it happen on some lawns and not others?
Why in some years and not others?
Are any hybrids known to be more susceptible to this? Tif 419? Did you find out what sod farm supplied this?
Why is it green in the front left corner? And along the sidewalk? What about the circle of brown in the background?
