This is pretty much the only service I don't offer to my clients but I'm looking into adding it to the list of services I provide. The trouble is I have never done weed control before. I've fertilized spread lime and over seeded when asked. But weed control ( like what Tru Green offers ) in the form of liquid weed control is something I've not done. I'm seeking advice and methods on going about this. Also products used with good results would be great as well.
