Dendrobium kingianum question
 

Hi, all.
This is my dendrobium kingianum that had no roots. It finally produced two new canes with new roots(woohoo!). When is it safe to pot it up? Currently, I have it in a plastic container with a layer of hydroton and sphagnum moss. I keep about a centimeter of water on the bottom of the container so it’s humid but water isn’t touching the plant itself.
Thanks!

Yay! Pot it up right now, with tiny roots. Don't let the roots dry out while pushing growth. Use some combination of medium/watering interval so it never dries out. Fine bark works well for many people for plants this small; medium bark later on.

This orchid is extremely hardy if the right conditions are met. You can pot your Dendrobium kingianum right now and it wouldn't skip a beat. For me, I have put my own Den. kingianum keikis in pots of their own even when the roots are as short as 1/4" long, and they have survived, so I have no problems believing that yours will be ok.

I have put some of my Den. kingianum keikis in pots with medium to large grade bark and others in pots with 3/4" granite. An overwhelmingly large majority of them have survived.

I have put my mother plant in diatomite and have had this orchid for about 13 - 14 years.

Given what I have said so far about Den. kingianum, it should give you an idea of what you can accomplish with this species.

One of their common names is the Pink Rock Orchid.

This is one species that dispels the notion of all species orchids as being delicate.

Thanks! I will buy small fraction orchiata mix. And pot it up in a small container.

Wow, Philip this is rough treatment for little baby plants:biggrin: but does show how hardy they are. So far I was able to grow new roots on most of my rootless orchids with the exception of a cymbidium. This one doesn’t move anywhere. It has new growth but doesn’t wish to produce new roots. I am ready to give up on it
Thanks for your help!

I had three of them I mounted them the one was a full grown plant and grew well land sprouted aerial roots but I guess I used too much moss and when it spiked all the spikes dried up. the roots were not healthy. So I put it in chunky bark mix and it took off and grew roots like crazy. the two keikis were mounted and did well but after seeing how the bib guy did I put the whole mounted block in a pock with bark and they are growing much faster now.

There is most likely a good reason for this behavior...

In the wild, Dendrobium kingianum is actually more of a lithophyte than an epiphyte. If it is growing as an epiphyte, it is growing on the lower parts of the tree closest to the ground.
