Hi!

About your zygo, if a few of pbulbs are wrinkled I would guess it is fine (provided that the pbulbs are older ones, of course). Older bulbs tend to become wrinkled and less fat than newly matured ones--this is okay. But if a majority (or all) of bulbs are wrinkled (even newer ones) then the plant may be either dehydrated or root-rotted. Be careful with watering...some people water their orchids too much because they want to "fatten" up the bulbs, in turn overwatering. Since you said "a couple of bulbs" I guess you're fine.

Miltoniopsis and Miltonias are different, of course, the former from Columbia and the latter from Brazil. Miltoniopsis are those "pansy orchids" with the really big petals. They have many leaves on each growth and each growth's clustered closer together. They're cool growing plants, originating from higher elevations. Miltonias are more related to oncidiums (their flowers sometimes resemble oncs more), and are warm growing. I've seen miltoniopsis plants called miltonias, and vice versa. What a lot of confusion!

The dying of flowers may be caused by stress by the move. Different environments take a toll on orchid flowers. I think so unless the orchid has some sort of serious health problem that it can't support flowers...

I thought milts (not sure which one) like fine mix because of fine roots. As long as the mix is fine enough.

Good luck with your orchids!
