I put down fungicide 3 weeks ago...and the dollar spot is still spreading like a weed in my lawn. Its starting to take over everywere even where I put extra down. Its been very wet here. Haven't turned on the sprinklers for 4-5 weeks now. This is also the first year we never weed/feeded the lawn. Could that of caused it. Someone please help. I don't want to lose the only (was) green thing on my property.
