Need suggestions on how to mount this large Den antennatum, please!

[susiep]

I have had this Den antennatum for many years and it has gotten out of hand. I cannot remove it from this basket so the old basket needs to be part of the new mount. I took a cutting off of it a couple years ago and it still only has a couple roots. (Very small delicate roots) So it definitely doesn't like change. Otherwise it is very hardy and can even handle the full sun in south Florida. Earlier this year I just turned the basket sideways and it seems happier now. The leaves were lighter, but I recently moved it out of the sun to prevent burning of the canes (I had never seen that before). It has been blooming continuously for over a year, maybe 2. I would like to groom it up a bit and eventually enter it for show. Any suggestions?
