I'm wondering, hoping, someone here knows what to do. I've only recently gotten into orchids and have been trying to rescue a Vanda orchid my mother had laying around the yard completely discarded. I found it with only two roots and two keikis coming out the sides. I made the ultimate MISTAKE... I separated the mum from the keikis thinking that would be easier to save all three. Needless to say now all three are suffering and I don't know how to get them to send out new roots. They are all rootless. Any and all advice would be welcomed please.

Did I kill the orchid? Is it a lost cause?
