I've already seen your beautiful palms over there, Jim. The Miltonidium is a really great color.
I have variable results with those guys too, so last time I had to re-pot one that kept falling over, I just soaked it, eased it out of the pot and straight into its new pot before it knew what happened. Sneaky-like, you know? It has stayed happy and now stands up too, thanks to the weight of the new clay pot I put it in. Didn't even add any new medium, (the old stuff looked fine) so it has a narrow air space all around the old root ball now which it seems to really like.
Hey, what happened with the orchid you potted up in the sponge pot?
