Greetings- I recently repaired some bare spots and areas where moss was. I put down some premium lawn top soil then seeded with Scott Ez Seed. It has been growing well but noticed after about 2 weeks this white puffy looking globs attached to the top soil. It looks something like popcorn, very white in color. Can anyone tell me what it is and if there is anything I can do to stop it? I have picked off these white clusters which come up easy but looks like they are starting to pop up in more and more spots now. I do wonder if there was something in the top soil. Any help and advice would be greatly appreciated.

Mike
