I just moved into a new home last summer, and I've never taken care of a lawn before. Towards last fall, I think I had brown patch and a local garden center told me to spray fungicide, and everything would be okay in the Spring.

Now, it's Spring, and I don't know if everything's okay. The segments that died last year (I learned of my problem too late) are still dead, but large segments of my lawn are not green, and I don't know what to do.
give me some idea let me know?
