Your plants are beautiful! I am aware these plants like to be mounted, but I really don't have any plan as of now, and nowhere I can think of to put it either, if it were mounted. No, the fronds have had no damage--that really has me baffled why they look like that. I've had the lemoinei before, and it lived for a few years with no problems (treated the same way as this one) and died, unfortunately, of scale. I grieved over its loss, as it was a really nice little plant. And now this one, I can't seem to make happy!
