I’ve been having issues with new roots on my Paphs aborting themselves, so I started using sphagnum moss as a top dressing to retain moisture near the surface of my potting mix. While I was reading about sphagnum moss as a top dressing I also found a few discussions about the use of live moss for the same purpose. I figured if I could get live moss to grow in my home conditions, I could eventually spread it to all my pots. That, and I thought this would be a fun experiment with materials I had on hand.Moss is always pretty, but why do you need a top dressing?
Thanks! I’ll update this thread with my progress. I know sphagnum moss is known for dropping pH, but I haven’t found anything on the pH regulating effects of live moss. I figure the oyster shell I have in my mix will buffer against the effects of the sphagnum.I think the experiment is quite pretty. I hope the moss does well. I've read
recently that moss is too acid for orchids. I have no idea if that's true.
I rinsed my moss a bunch and still had clay particles stuck to them. I decided it was good enough and soaked them in diluted hydrogen peroxide for about 20 minutes. Hopefully it took care of any hitchhikersI tried using local moss once. Bad Idea, I couldn't get it clean enough. I used live moss from eBay vendors and now if I need some I just pull a piece off one plant and move it where needed.
