So I'm thinking of using Espoma organic lawn feed products for my clients' lawns. I'm wondering if I can do that and still claim to my clients that this is indeed 100% organic fertilizer. If not, or even if so, are there better products to use? I want to be able to tell my clients that we're using some of the best product available. Michigan law requires no phosphorus in lawn fertilizer, and also I will not be able to use any kind of herbicide on the lawn either, that which requires licensing which is extensive and takes over 2 years to get. I just want to be able to say that the stuff I'm using is kid and pet friendly, and will still help lightly feed their lawn without nasty harmful chemicals. Thanks in advance for the replies!!
