As Junebug said, it might be the mount. I also have a Schom on grapewood and it's growing like nuts. When I first got it about six months ago, it came as a division that the specimen plant looked rough. It came with about 5 pseudo bulbs of which two quickly rotted away.
It now has ten bulbs and an eleventh popping out recently. It went to spike in May, but the guy I was counting on to water my chids while I was down in the Virgin Islands on vacation, flaked out and the spike burned off.
Don't know what species of Schom I have (not seeing the blooms as of yet) but I do have one of the pseudobulbs about 14" long and almost 2" thick.
I treat it like a Vanda and water it every day and multiple times.
Now, as for your delimma, you can always send it to me here in my warm sunny climes of So Flo for rehab
