Dendrobium losing leaves

[Shiffdaddy]

Ok, Thanks you guys. So basically those bare canes will now just be there as support for the new canes that will be coming up with leaves but those old ones will never bloom or produce more leaves?

No problem! You are correct in that the old canes on your den will no longer produce leaves. Since your den has fine roots and green canes, it will most likely produce baby plantlets on the cane(s) or start a new plant from the bottom of the cane as one member mentioned above.

Regarding the possibility of bloom on old canes, well, they say never say never.
These dendrobiums usually send out spike off new and old canes. I have some that send multiple spikes per cane although most send up one or two per cane at a time.

Yours lost all the leaves due to stress, so I'm not sure if the old canes on your den will produce flowers or not. Let's hope it will in the future when it recovers.

Bare canes won't grow new leaves but they will spike sometimes. I think it depends on genetics. Some of mine behave this way and some do not. Canes with leaves can have multiple spiking sessions. I've observed as many as 4 on some of my dendrobiums.

Even though the leafless canes are no longer attractive it's best for the plant to not remove them until they are shriveled and yellow. Removing them prior to this stage can result in a severe set back of growth. I learned this the hard way too.

Another thing worth mentioning...Dendrobiums are typically top heavy growers and it's not uncommon for them to take an occasional spill resulting in a broken cane. If kept at a comfortable temperature and shaded, a broken/detached cane will generally develop a keiki within a 2 or 3 months. No special care is required. Just toss it to the side and check on it every now and then. The keiki wil begin growing roots shortly after it appears and it should be watered regularly when it reaches this stage. After the roots have grown a few inches it can be potted up or mounted and you'll have a whole new plant.
