How can I work live moss into my foam background in vivarium?

I am making a foam background for my vivarium. I used great stuff, covered it with silicone and added peat moss mix and coco fiber to the silicone. I found some live moss outside (I have quarantined it) I want to attach it to the wall but I am not sure how. I know with epithetic bromeliads you can just silicone them on and they will thrive. Can you do that with moss or staple it. Any suggestions would help. Also I have not been to successful with moss in the past. I have always gotten the stuff you buy dormant and then "bring back to life" I always kill it. I am hoping since I have live moss it will do better but I would love some suggestions on that too. Gonna try to keep it in the shady parts of the tank and mist it. I think my problem in the past was my soil being to soggy which is something I am hoping to change by adding coco husk chips to my peat moss coco fiber mix. Even with my false bottom that stuff stayed pretty soggy. Anyway, I have had a vivarium for about a year now but I am new to the foam background thing. I would love any input on the matter. Thanks.
