Hi Marion,
I don't use chemical fertilizers on my lawn because I'm afraid of my dogs ingesting it when they clean their paws, and also bringing it inside on their paws and having it all over my floor so my little one will ingest it on his hands when he crawls around. I've found a great company with natural fertilizers called Gardens Alive. You can find them online and they have GREAT products for all your lawn care needs! Give them a try!
