I have noticed about 2 months ago I start have yellow spots over my lawn and some sport are becoming dry and dying. I have put fertilizer and iron on it but it seen to be getting worst and spreading. I am wondering if I have SAD. What can I do. Thank you.

Your grass may have a chinch bug infestation. The Florida Extension has a very good fact sheet on St. Augustinegrass (http://edis.ifas.ufl.edu/LH010) and it describes what seems to be your problem. You might want to contact your local Extension office in Lake County, (352) 343-4101, http://lake.ifas.ufl.edu/. They will know more about this than me, since I am located in central Illinois. I hope this is helpful to you.
