Dendrobium canes turning yellow

[Becca]

Hi Everyone! Happy weekend! Just wanted to get some opinions from everyone one here....I acquired a Dendrobium Woo Leng at my local orchid society meeting in January of this year. I know some dendrobiums like to to pout, kick and cry and then try to die just to scare the crap out of you but this one seemed ok after about a month. But then the big move came in February to my new home....they got boxed up (I left the lids open) and they stayed that way for about 3 or 4 weeks in the living room of the new house unfortunately. All the 'chids did well....no problem with cold damage on anything since it was a fairly warm day for moving and they didn't sit anywhere cold. Anyways...this dendrobium decided to start acting up after we moved....first it was the tip of a couple of canes and the base started yellowing...but nothing was near the rhizome so I was just keeping an eye on it. Now the yellowing is starting to go to the very base of two canes and I'm wondering if I should cut them off? They are the two older canes out of about 5 or so canes...one newer cane has an active eye so I know new growth is coming. But I'm afraid the yellowing will spread through the entire plant. The two canes are still green in the center and everything is still firm. What would you do?
