I have been running a small lawn care/landscape company for 6 years now and up until this year it has been just a side gig. For the 2012 season I am going to try and make a full time run at it. I have worked for lawn companies over these past 6 years but everyone I have worked for has been so secretive about the fertilizing aspect of the business. Basically what I am asking for is if anyone can give me a lead on where I can either take classes or would be willing to train me in the Twin Cities area. Anything you can provide helps. Thanks!
