leaf loss or "Palm Tree stage"

[talyce66]

I bought this vanda about 3 years ago and dont know what kind it is but its a vanda anyway. The seller told me that it was about 25 years old, and boy is it big. However, it hasn't bloomed in over a year and the leaves are turning yellow and falling off.
I was told it was going through something called "the palm tree state." I was also told something about taking it out of the basket and laying it on its side. If it had roots up high enough I would have just cut it off and not had this problem! Any suggestions?
