What Is Wrong With My Grass?

Question

Why does my grass look like this?

Answer 1

One possibility is improper watering. During the winter, change the frequency of the watering, but not the amount. I've attached a publication about proper watering in Florida landscapes. The most common grass planted in Florida is St. Augustinegrass, which goes dormant in zone 10, or when the temperatures drop below 50 degrees. It will green up again in spring. Applying fertilizer at the wrong time also can affect the grass color.

It doesn't really look like a fungal disease, but I have included information about fungal diseases as well.
