I have moss growing in fairly large patches on my lawn (thanks global warming!) and I don't want to use Moss-Out, because I think it would be poisonous to fowl. I'm not sure about that. My friend who lives in a coastal region where they have lots of moss problems said you can put just lime on it, and it will kill the moss. Would just straight lime sprinkled on the moss areas harm my birds? It's going to take over the lawn! Thanks!
