This Orchid (Myr. grandiflora) is getting too big-OR- He's not fat, just big boned!!

this is an unusual problem to have...but this orchid has had an unusual growth spurt....a great problem but i am still stumped

I have it mounted on a twisted piece of oak that is about 4.5' in total length. the plant is probably 12 years old and i got a division when i got her so it is a very mature colony.


this growth went through the bark (tore it right open) and is about 2-2.5 times the size of the next largest growth which was last years biggest and itself is larger than the rest.

here is my hand for reference. i have 10-10.25" spread from pinkie to thumb.

my concern is that in a year, if this trend continues, he will be way too big for the current mount and be quite difficult to remount with a 4' log in the middle.


what should i do?

leave it and assume it will not grow at this clip but will level off?
remount it now to a larger pole (i am not sure how to handle anything much larger to be honest)
try to split it now (i don't know if i can cleanly do so) and get the huge new pieces in/on a tree to just do their own thing ( i am fine with this as long as i have some still able to be moved.


thoughts? thanks
