Jumping in from Maryland. NOT exactly a tropical kind of a state.

I have had 2 Epis now for 7 years. Got them in a trade from kachinagirl in CA.

Last year--one of them bloomed for the first time--and is covered in buds (15) this summer.
One has opened--and am waiting for all the consecutive blooms to open.

The other one--an "Ackermannii" also was covered in blooms....What's going on?
I keep fearing this may be their Swan Song.....

I have to bring them in for thew winter and they hang in semi sun by my LR window.
Yes! They are heavy!!! I always fear they will pull the hook out of the ceiling and come crashing down.
My heaviest is my RicRac cactus. Man! That weighs a ton!!!

How would one go about "cutting it back"??? I would not know where to cut them.
Seems the blooms always come from the old, scraggly fronds. If I cut those back--how soon would it be
before they re-grew?
One of mine--the 2nd picture--is beyond spectacular when in bloom--but the fronds look old and calloused--
yet that is from where all the bloom buds come.

Both of these were re-potted 3 years ago in 10" HB. They really perked up after that.....they still are hugely
root bond (I presume they like it that way and blloom better in that state) and I am afraid to "mess with them".
Mind you--I do not live in zone 9 or 10. My zone is 7a. Baltimore. These plants cannot stay out for the winter...

Pic. #1 and #2--my "ackermannii in bloom in June.
Pic. #3 and #4--my "other Epi"--that just bloomed last year for the first time. Do not have a name.
It totally blew me away by its beauty!!!
