Ah! You are not familiar with rhizome clips.... They are handy little bent wire things made for holding rootless or semi-rootless orchids down in their media. You can definitely make your own. You want the oldest pbulb to be low in the media - so new roots grow within the media. So you need to create the wire set up so that it can exert downward pressure on the plant to hold it into the media, plus help stabilize the plant. As for the pbulbs - the older ones will wrinkle. Can't help that now, just concentrate on keeping new growth healthy!
