I went and looked at one of my customers today. Last year was the first year I started there. Last year was the first year she went organic after using CHemlawn or whoever for years. I got an e mail from her this morning that the whole lawn looks dead. I went there and all of the tips are brown, with either tiny black spots or purplish color. We did have a rough winter this year with snow being on the ground for a good part of the winter. When I left there in Ocotober the lawn looked fine. Snow mold? THere is a lot of it around me but it wasn't matted down. Could it be rust? THanks!!
