Question
I have some white stuff growing on the soil outside in one area of my yard.  It was there last year and i scraped it off and tried different things on it but it came back this year.  I have been cutting  back on watering but it doesn't help.  The white material can get thick. It's appearance looks like the surface of a caulflower.

Answer
Hi Judy, It is a fungus. The majority of it is underground, what you see is mostly the reproductive structures.  You may be able to control it with a fungicide applied regularly but I would just break it up with a hard rake and not worry about it.  Jim
