My moss wall kept failing until I switched to a different glue

I used to make moss walls with that white craft glue you get at any store. It worked okay for a few weeks, but then the moss would turn brown and fall off. I lost three projects in a row last spring. A guy at the plant swap in Denver saw my sad jar and told me to try a specific aquarium-safe silicone, the kind for fish tanks. I got a tube for about eight bucks. The difference is huge. You apply a thin layer, press the moss on, and it holds it in place but still lets it breathe. My latest wall in a big pickle jar has been green and happy for over four months now. Has anyone else found a better adhesive for holding live moss in place without killing it?

Totally agree with @james_martin93 about the silicone being flexible. That stuff is a miracle for keeping moss alive. I had the same brown mess happen with regular glue before switching.

That aquarium silicone trick is a total game changer. The key is it stays flexible and doesn't seal everything off like a plastic coat. Regular glue just suffocates the moss over time. I've even used it to attach small pieces to driftwood for terrariums, and it holds up to the humidity. Makes sense since it's made for wet environments with live plants. Total lifesaver for keeping things alive.

I tried that aquarium silicone on a little moss wall I had in an old pickle jar. Worked great for months until my cat decided it looked like a toy and knocked the whole thing off the shelf. The jar survived but the moss got scattered everywhere. I just pressed it back on with some extra silicone and it bounced back in like two weeks. That stuff is forgiving for sure.
