I need suggestion for my nobile-type Dendrobiums

[grandmapenguin]

I need some suggestions on these two Nobile Dens. First of all, one is withered more than the other. Would you put them outdoors to get a bit of chillier temperatures Do they even look alive

Should I try putting them into Leca to change their Media I have a third one that I bought at the same time and it still has leaves and going great guns. These all bloomed several months ago.

i think they are supposed to become like this or at least there are dens that only flower when they are leafless and dried up a bit. I am still waiting for the dendrobium book to be delivered so it's better to wait for more experienced members.

Hi Grandmapenguin,

I don’t know if our situations are the same, but last year at this time, I bought two dens – both in full bloom. Earlier this summer, one den had 4 new growths (new canes? Basal keikis? I’m not sure what they are!) The other den lost one mature cane and one that never did get very big. The remaining cane lost all its leaves. However – I left it alone and continued to water as usual and it was the first and only orchid that has ever re-bloomed for me. See the attached picture – blooms, but no leaves! Don’t give up on it yet!

I’m sure someone more knowledgeable will come to help you soon.

The first one looks reasonably good to me. You'll probably have to be pretty patient with these. It may take a while for them to get back on track. I would be inclined to repot them, small. Maybe in 1.5 or 2-inch pots. If there is root loss you may need to stake them for support. Then treat them as they would expect for the season. In other words now that you're headed into Autumn, gradually decrease water, watering only enough to keep the bulbs plump, etc., etc. (general nobile-type care). I'd be interested to hear what others think too.

neworchid, you situation is not the same as grandma's because you have different types of dens.

OH MY Neworchid that is just gorgeous. You give me hope

I failed to mention. Both of these did rebloom without any leaves. The third bloomed with leaves. One I bought with blooms on and it gave me two Keikis and rebloomed. They are prolific little buggers. LOL

I am very tempted to try the Leca since I want to see what the roots look like.
I may just try one.

Does anyone think a good chilling outside in about 10C or 50 degrees would be to their liking?

G'Day Terry

Welcome back! If you look at this thread Spent flower on Den Nobile there is a link to a site I put on there, also a good reply from Kevin.

Cheers

I would leave them in bark. They like it reasonably dry. Maybe repot smaller, maybe not.

The old canes on nobile types get pretty wrinkly. Don't cut them off till they go yellow, dry and mushy (after a few years).

Give them plenty of light, they will take a fair bit of direct sun (once they are sun-hardened). Cut down on water over winter (I still water once a week). No fertilizer. Over winter they should put out new spikes, and about the same time start new canes.

That is what all mine have done anyway. Nobile type dens are pretty easy-going.

I have 1 nobile den which I bought almost a year ago with 2 active canes which were in bud. The blooms were just beautiful and so many. I did repot this in S/H and the thing took off like crazy. Since May, it has 7 new canes. I do still have it outside, the canes still have their leaves at this point. But it seems to have stopped leaf growth and is getting ready to lose them. Since this is my only den in S/H, I'm concerned about it getting too much water and thus wouldn't produce buds. I have just started to hold back water. I'm half tempted to repot in bark as I'm not sure how to proceed growing in S/H(I guess I should have thought ahead duh)

i grow all my dens in straight lava rock in clay pots. i drown 'em once a week. they grow like weeds

[11Orchid126]

Stop all fertilizer for nobile dens in late August. In September start cutting back on water. By the end of October stop all water. If the canes look too shriveled, mist them. Don't resume watering until the buds show. At that time give the plant baby sips. After blooming, resume water and fertilizer (always low nitrogen). For the fall chilling refer to the Yamamoto site. Mr. Yamamoto is a hybridizer of nobile dens and has a wonderful article on their culture.

Are they nobile types?
