This lawn looked great two months ago...I really don't know what happend. We moved in to this house one year ago. The first thing I did was start the Scotts 4 step program. I also did some basic spot repairs. I had the lawn looking stellar this spring. It was really thick and green. But now its gone to the pictures below and I need to know what I've done wrong. http://s87.photobucket.com/albums/k138/jddebord/Yard/ I'm more concerned with the back yard since it is much worse than the front, but I would appreciate any input that I could get on what I need to do to take care of this as I am new to the St Louis area and am not familiar with the types of problems that are experienced in this region. I really enjoy working in the yard and trying to maintain the best lawn on my block, so it is really killing me having a yard that looks like this. I'll have to admit that I do not have a sprinkler system installed yet, so my watering isn't as regular as I would like, but this issue doesn't look like its due to a lack of water. Thank you in advance for your feedback.
