I'm having a problem with my yard and am seeking advice on how to deal with it. I have about 1/4 acre of well maintained yard but for some reason it is all gradually turning from green to brown as brown patches of grass have been taking over my yard over the past 3-4 weeks. It is usually lush and green this time of year. I've attached a picture of the problem. Here is some background..I live in western PA. Not sure what type of grass is growing in my yard. It's been raining more than usual. Very wet yard with few sunny days. I have my yard treated/fertilized. Last time was May 1st. Any ideas?
