This could be many things, however, this time of year, the most common
brown spot to happen quickly is brown patch fungus. The area may
appear to have a doughnut shaped appearance. The base of the blade
will slide out easily and have a black shiny appearance at the base of
the leaf.
This disease is most likely to be observed from October through May
when temperatures are below 80 F. It is normally not observed in the
summer. Infection is triggered by rainfall, excessive irrigation or
extended periods of high humidity resulting in the leaf canopy being
continuously wet for 48 hours or more. It can be transferred to other
parts of your lawn by mowers, walking through it, etc. A good
fungicide should be applied to it every 14 days, 2-3 consecutive times
to get it under control. Once the fungus is controlled, you can then
start fertilizing it to help with the recovery. Call us for a free
