    Arrow D. C.K. ai 'Oka' x canaliculatum help

    Hi New to the forums and the orchid community.

    Some questions about the orchid mentioned above. I been watering the orchid once a week. Just got a skewer for telling when to water the orchid so maybe I will be watering more then once a week if need be. I also just use the tap water from my kitchen sink and let it run in the pot for a few minutes then I put it in the east facing window. I got it with the flowers all off the plant. So I cut the stem all the way down. I did this before I read that your suppose to sterilize what ever you use for cutting. I also been putting it outside during the day to get better light then take it in after work which that is around 9 to about 11 some nights. I live in boston mass so the temps for highs have been in the 70's right now and the lows around 55. I bring it in before it goes down that low and my house with no heat been staying in the 70-73 range.

    I just wanted to know is that ok for the orchid what im doing so far. Is it ok to keep moving it outside and in? I also dont know if I should make it rest or just water and fertilize all year long. I also haven't fertilized it yet all i have is liquid housplant food by miracle gro. Could I just use this? It says its a 8-7-6.
    My big fear is to not get the fertilizer right. Ill probably ask more questions but need to go to work for now.

    Bye for Now

    Welcome to the forum! I don't grow that type of orchid, but there are several folks here on the forum who do, so you will get an answer.

    Hi and welcome to the forum .

    I have not been able to find Dendrobium C.K. ai ,but canaliculatum is an Austrailian species with 4 main varities . Iwill have a read up and write some cultural notes for it ,as it will be rather dominate in that cross.

    Hi Storm, and welcome to the forum!

    I live in Marblehead, just north of Boston, and I wouldn't be leaving anything except Cymbidiums out around now. We're getting into the 40's at night from time to time. I personally don't put my plants outside, because I've found they're happier with more consistent conditions. I do have excellent light inside, so I can do that.

    Your Den is: Den. C. K. Ai 'Oka' x Den canaliculatum. Luckily that mouthful has a name - those are the parents. Your plant has the cute name, Den. Pumpkin Patch.

    I don't know if you're familiar with orchid naming. If not, this might help: http://www.rv-orchidworks.com/orchid...ead.php?t=4163

    I don't know the Den culture that well, so I'll spell out the genealogy for Murray, who can best guide you.

    Pumpkin Patch is:

    50% canaliculatum
    12.5% discolor
    12.5% phalenopsis
    12.5% schulleri
    12.5% tokai (an antelope-eared species)

    When you fert, use 1/4 strength. Most orchids prefer a light fert more often. "Weakly weekly" is what we say. As for a winter rest, I'll let Murray opine.

    Thanks Piper ,I do not know tokai so had a quick search and found that it on the C.I.T.I.E.S list and comes from American Samoa , Fiji , Tonga . As for the others canaliculatum, discolour, phalenopsis, are Austrailian and schulleri (schuleri) from northern New Guinea.

    As canaliculatum is the dominate species in this plant here are the cultural requirements and what the books say about it.

    Dendrobium canaliculatum is a variable species and has many forms but there are only 3 or 4 named varieties ,with all coming from Northern Queensland (north of Rockhamptom).

    Cultivation

    All the forms require similar conditions and are cold sensitive, that is they hate cold drizzly weather. They also require a minimum night temp of 10C, a small pot of coarse mix or preferably slab culture. The plants need humidity and high light levels and must be kept dry over the winter months and fertilized with care..

    Now for the second book which is Dendrobium Orchids of Australia .

    They have three distinct seasons Growing , Resting , Flowering.

    Growth……. Late spring to early autumn , copious water at the roots ,plenty of fresh air , high temp but not high humidity. In their natural habitat this is the wet season .Rain falls nearly every day , mainly in the late afternoon.


    Resting ……Autumn to early winter , Keep dryer than most Dendrobiums .It does not hurt to let the pbulbs shrivel. If in a greenhouse have the plants up high near the glass in winter .If the green house is unheated, it is okay to keep the plants totally dry and near the top ventilators .
    Note… If watering and shading are not reduced at this time a new growth will appear . The growth at this time is distend to fail.


    Flowering……Late winter to spring , just a little water to keep the pbulbs from shrivelling to much and to keep the flowers firm.
    Water temp should be not less than 13C or 55F .

    Slab culture suits best but if grown in a pot ,a very open mix and the smallest possible pot .
    When crossed with large pbulbed plants it reduces the plant size considerably with good upright spikes and numerous flowers.

    A note for the vegetarians amongst us ???????????????????????????????

    The pbulbs are edible when stripped of the old leaves and baked..

    Thanks for the welcome and the advice.

    So right now it should be resting, so would the watering once a week be ok or should I do less? Also I am not sure if my east facing window gets enough sun. I will not put it outside to get more if the plant is not going to like it. I was putting it in the yard just to get a little more light then it does inside. Also should I just hold up on fertilizing it while it is resting? Real new to orchids and feel like im going to kill it .

    Thanks Again
    Storm

    I would be with-holding water and fertilizer and say just a misting (light)once per week.A south facing window would be better than the East window.

    I'd still water and fert for now. I have a deciduous Den. that goes without water all winter and it's not ready yet. Keep your guy going a bit longer. I'll holler when mine starts dropping its leaves. I'd think the timing should be similar.

    If you don't have a southern exposure, just give your guy as much light as you can. A Den. up here wouldn't mind flouresecent lights if you can't give it enough daylight. Just a thought.
