One lawn that I mow is covered in danalions. The homeowner would like to get rid of them. The two lawns that border hers are also covered with them. I am not licensed to apply Pesticides or chemicals to lawns and informed her that she would need to hire someone who is. Which was fine for her. I also told her that I think that if the other two homeowners does not do something to kill the danaloins in their yard that she would most likely be wasting her money due to the flying seeds. For as soon as the killer stopped working that her yard would again become infected again. I would like to know if I gave her the correct information. Would it be a waste of money to attempt to rid her yard of the danalions if she has a yard on each side of her that is also infected with them? Thinking maybe her and her two neighbors could get together and hire one guy or company to take care of all three yards at the same time. Seems to me that would be the best idea. They may even get a price break having all three treated at once by the same people. Did I give her decent information and would dealing with all three yards at once be better in the long run for her own lawn?
