I have been getting brown dead spots on my lawn.
Could it be a fungus?
And if it is could it be caused by evening watering? What can I do about the problem?

The brown spots could indicate a fungal infection, but they might also be the results of dog urine or might simply be cool season grasses going dormant in hot weather. If the latter is the case, it will green up when the weather cools; if the spots are urea burns, you'll want to rake out the old, dead grass and grass roots and reseed the area. Fungal infections can be treated with fungicides, but the problem will return unless you correct the cause. Over-watering and poor drainage contribute to fungal diseases. If possible, water in the morning so the grass can dry out before nightfall. This will go a long way in keeping your lawn healthy and free of fungus.

Best wishes with your lawn!
