I am starting my second year in the lawn care industry. During my first year I have gained 0 commercial accounts (didn't try for them), about 40 regular residential accounts and around 10 customers who call me when they can't get around to it themselves. Quite a few of my residential customers are asking me about weed control. I used an Ortho product for post emergent broad leaf weeds last year that worked pretty well, however I would like some advice on a pre-emergent for broad leaf weeds as well as advice for pre and post emergents for weeds OTHER than broad leaf. Any help would be greatly appreciated!
