Help! Possible dendrobium?

[Loriorchids]

Hello again,

I was given another orchid by a person to keep and help. As I have mentioned in other threads, I’m new at this and as I’m starting I’ve been given orchids to save (huge responsibility for me!).

Anyways, I have this one. It only has canes and there’s a cane that developed from another cane and developed roots! And on the pot, it was the new growth that was sticking out of a hole.
So here I am trying “to save” this orchid and while taking it out gently from the pot it was the new growth broke

There was like a fungus on the medium (like white cotton). I cleaned it out and sprayed it with fungicide…(still super sad to have killed the new growth tho).

So Here I have this orchid, I have no idea what kind of flowers it gives, it doesn’t have leaves, and it only has canes that seem super dry (see pictures).

1. I’m not sure if I have to take off the cane that developed roots on the other cane.

2. I’m sure the new growth will die since it broke when trying to take it off, but should I be doing anything else with these long shoots?

I have looked all over the internet and they all have when to repot and other info but I can’t find any information on this orchid (I believe Dendrobium) that has no leaves and what do I do with it to help it!

Thank you in advance!

EDITED:
I added the pictures of the roots after taking it off the pot it was.

Yes, it's a Dendrobium.

Next time show photos here before doing anything. You're learning but it's easy to make more problems than already exist by being too aggressive.

In the future don't be so meticulous about cleaning up plants. All you needed to do was take it out of the pot, shake off old medium, and repot into fresh medium. You might still have the new growth and the plant would have a better chance of surviving. Now you know how fragile and easy to snap are new growths.

Orchids tend only to make new roots from new growth. If you damage old roots and/or break new growths you make it much harder for the plant to recover. Sick plants only have a few chances to make a new growth and new roots.

I think your plant probably has enough stored water to make another new growth, even with the damaged roots, and may go on to survive. Had you cut off all the roots, like many people advise on YouTube, the chances of survival would have gone way down.

The new growth with roots up on the old stem often happens when this kind of orchid gets into trouble. Many people call a plantlet not growing from the base a keiki. Its roots are long enough to separate it from the plant and grow on its own, but I would not do that yet. Set a spray bottle near the plant and spray just those aerial roots a few times a day, until the keiki has plumped up and looks better. I would not separate it until the whole plant is again growing vigorously. These roots are the best roots the plant has now and I wouldn't remove them.

Fungicide is very rarely indicated unless you know your plant has a fungus and know the fungicide you have treats that fungus. Not all fungi are susceptible to all fungicides. White cottony fungus on medium only attacks dead plant material, not living plants. It's a sign the medium is old. It won't hurt the living plant. I wouldn't treat a plant in medium with white fungus with fungicide; I would just repot the plant.

As for now - put the plant into a small pot that just holds the roots, and has room for another growth. Fill it with new medium. Medium bark, LECA, lava rock/scoria and larger pumice are all fine for this kind of Dendrobium. You will need to stake it carefully so it doesn't wobble at all, because that will harm new roots when they form.

Water the medium when almost dry. The first time you might want to soak it for a few hours in the sink. Continue spraying the keiki roots several times a day. Keep the plant in a warm and humid place.

It should eventually make a new growth from the base, then new roots from that new growth. From the point of new roots make sure it doesn't dry completely. Dens use a lot of water when pushing new growth. Some orchids prefer getting dry between waterings but not this kind of Den. I would also begin fertilizing when the roots begin forming. A very small amount of balanced fertilizer, like 1/8 teaspoon per gallon of water, could be used at every watering.

If the main plant begins dying it would be time to cut off the keiki and try to keep it going. I don't advise that unless the base of the plant dies. If you need to, cut the stem below the keiki, taking a piece that is alive above the cut. Lay it sideways on top of some damp sphagnum moss in a shallow tray. Rectangular plastic food containers work well. Keep the moss just moist. It will push a new vertical growth and begin growing. At the time new roots form on the new shoot you can snip off the upper and lower parts of the original stem and repot the keiki into something larger, but just large enough to hold the plant and another growth.

Been there, and done that (many times).

There is nothing you can do for the new growth that broke off. Leave the stump on the old cane, and the plant should start another.

The keiki on top of the old cane has some roots, but no leaves at this time. I prefer to leave it on the mother plant, till I see the next growth starting. At that time, you can gently put a little sideways pressure on the base of the keiki, and take it off the old cane.

I usually start such keikis in a small plastic pot with spaghnum moss (= constant moisture). Once it has 2 or 3 canes, you can move it into something appropriate for mature plants.

Thank you!

I did replant with the new medium. The new growth broke off while trying to carefully get it out of the hole, so it was VERY fragile.
I did not cut any roots. They looked dry, not rotten, and I did place it on a bath and placed a stake because the little that I know, I understand Orchids don't like "moving" much.

Thank you for the advice on the new growth with roots on the mother plant.

This Orchid love started as an interest in "how to keep an Orchid alive" (given to me as a present), and this "rescue mission" threw me off!!

Weird to say I feel responsible for the health of any Orchid now! So when people see my Orchids, they are like, "Here! I think this one needs help!" I get a little anxious thinking, "of gosh...please don't die on me."

Again, thank you! Let's see what happens!
