Anyone of you heard about Fiesta weed control? I'm trying to get my hands on it but it seems rather hard. Here in Ontario/Canada, since 22nd April 2009 there was a pesticide and herbicide ban across the province, so we were force to use some organic weed control that really didn't work. 12 months later Neudorff North America release a new weed control call Fiesta. The main active ingredient is Iron in the form of FeHEDTA. So mainly a overdose of iron to weeds that kills them, but not the lawn. Says it works withing 48 hours. Anyone else heard of that? If so how much was it? any additional info on the product?
