    Default Dendrobium nobile newbie

    Hi,

    I posted in a panic a couple weeks back, and I think I' doing a good job of giving my dendrobium nobile orchids "a good leavin' alone" as indicated. The are on a sunny south facing window, and get down to about 50 degrees F @ night. I'm posting a photo (detail of canes) , to ask whether I should water at all. I notice some puckering on the canes, though they are both retaining most leaves, and seem otherwise healthy. Any sages to assure me all is fine, or give them a drink (they haven't had any water in a few weeks-- the room is lightly heated).

    The heat is probably drying them out a bit. Give 'em a light drink and make sure they drain well.

    cheers,

    Yea, they need a drink They like to be kept slightly moist outside of their dormancy. Also, dont be worried if they lose their leaves as it gets closer to winter, that is normal.

    Thanks, BD.

    I was told at the Orchid class I attended that when you do water, give them a thorough soak under running water, and let them drain.

    Heeding your advice, I gave them a quick drink & drained them in the sink thoroughly, and will do every 2-3 weeks or if the stalks prune, during this dormant period.

    Thanks to kiwi, too. Though we are still a few weeks from actual calendar winter here (& the shortest day), it's getting to freezing at night now, and they are getting their necessary cooling at night (under 55F). How long is typical dormancy in winter? Is it dependent on daylight amount?

    Pretty much, i let mine go dormant about April, and i bring them out around August or September. Just reverse the seasons for the Northern Hemisphere. So what i do, is i stop watering completely, and dont give it water for a month. This tells it "oh, i need to sleep". Then i will give it a little dribble, enough to wet the surface, once or twice a month, just to keep it from drying completely. In the wild, D. nobile experience this as the wet monsoon season has departed, and is followed by a dry spell. Then, around the end of Winter, the plant should send out a new growth, signaling the start of the new season

    Hi any & all,

    My Nagasaki dend. nob. has set a few buds. Does this mean dormancy is over, and I should now start watering more frequently? The Sailor Boy dend. nob. beside it is still dormant-- that is, no budding yet, and dropping a few leaves. The Sailor boy is also a bit puckered in the stem despite a pretty good watering I gave a few weeks back (to both orchids).

    One other thing-- when I bought these, the folks at the greenhouse sold me an orchid fertilizer: GrowMore premium orchid food, a bloom formula 6.30.30. Is this even the right formula for Dendrobium nobile, and if so, when does one begin to fertilize again after dormancy? And how often?

    Thanks & a Merry/Happy to all...

    Default dendrobium nobile and its hybrids - culture

    I thought a couple of shots might help - showing the emerging flower buds. Pic taken today,how to do it, explained below the pics ...

    I stop watering in September ; put the plants outside in early October - Southern England, night temperatures then sometimes below 10 C ( 50 F) no risk of frost. I actually put them into an unheated lean-to greenhouse, to give some protection against frost and leave them there as long as possible. If we have a hard winter (2010) , that's 3 weeks... This year they were out until 7th December, and the temp went down to 5 C ( 41F) , on a few nights, 3 C ( 37 F) once. Never watered ! Important. Wet and cold = death. Dry and cold = riepening canes.
    Took them back in when we had a frosty week, have watered once only. Canes shrivelled - not important. When the buds are definitely flower buds, and not possibly keikis, I'll water again., once. After flowering they will start new canes, and when new roots proliferate, I will soak them daily and keep them warm to get the best possible canes. Note, the canes without buds will be the first to flower next year - sometimes a few months of ripening is just not enough - depends a bit on variety.
    Hope all this helps ?

    Nobiles can be watered lightly during their dormancy - but no fertllizer. It's the fert that causes the dreaded keikis instead of flowers.

    Default Orchid Keiki or not?

    Thanks, Orco & Dorset. Sorry for delay in responding-- I swam out of the Christmastide long enough to take a photo.;-)

    Here's a photo of the buds or keikis: someone more knowledgeable than me make the call.

    If they are keikis , do I cut them off?

    I have not fertilized these orchids since I bought them in late October.

    Looks like you've got flowers on the way.
