I made my first app. @ a new customer's home, today. I have 3 other customers in the small gated community, and the only time I've been on his lawn is the one time he asked me to mow for him, around May (his rider blew up and he was waiting for his new ZTR). Anyways.....in the rear of the property (today), I noticed about a 6-8' dia. ring of purple-ish mushrooms....not growing very tall. I'm doing some research (since I've been home). These things are nasty pests, huh? I'm all ears on your experiences with them. Thanks.
