How can I tell what is causing the brawn spots in my fescue lawn?

Question

Would it be too much or too little water? or fungus?.....or? And how do i tell which one it is?

Answer 1

Just a thought...I have recently began having brown spots in my yard but I finally figured out what it was...the exhaust from the riding mower that I bought two months ago. Wherever I stop and change gears or pause for a few seconds I end up with a nice brown patch of grass where I'd never had a problem before.

Another consideration would be grub worms, they eat the roots and cause those brown patches as well.

You should only water 3 times a week for an inch at a time. The roots need a couple of days in between to dry out some and strengthen, especially if the grass is shaded in some areas..

Answer 2

Usually fungus is because too much moisture which is sometimes caused by night watering of your lawn. You should know if your lawn is lacking water, because the grass gets a grayish green color and looks unhealthy. Outside of the previous answer above, animal urine will cause brown patches too.

Answer 3

My friend had the same problem awhile back and believe it or not, it was caused by a neighborhood female dog taking a squat on his lawn. He had the brown spots analyzed and that was what the report said. Her urine was causing the brown spots.
I thought it was funny he went so far as to have them analyzed, but then I realized how hard he has worked on that lawn.
Good luck.
