Update :
Good news! Since the bottom leaf fell off there has been no progression of more leaf shedding so thankfully it was just time for that leaf to fall
However the dend does seem to be sulking. The new leaf shoots that were there when I bought it are not growing. Are they supposed to be or is it sort of dormant while it has flowers in bloom?
Also as I was afraid of the moss is staying a little too wet for my liking although all roots look good. The bark mix was too dry for the tiny pot. Would it be ok to mix some bark in with the moss? I'd like to try s/h at some point in the future but I'd have to order the leca so that isn't an immediate thing I can try.
