This is an example of what can happen if a fungus invasion isn’t taken care of in a timely manner. In a situation like this, treatment can still be helpful for the remaining grass, but it becomes more damage control than anything. These areas will need to have sod installed and watched carefully for recurrent fungal issues. This post is not here to “bash” the owner, but simply to bring awareness to what can happen and why we stress the importance of fungicides this time of year. Hope this helps, and if you think you have fungus and need help identifying it, let us know!
