- I get many questions about the dendrobium nobile type hybrids and their seasonal cycle - especially when they don't behave the way we expect them to.
As always, thanks for watching.

I like what you pointed out at the end of the video about the plant and preference of the size of the pọt. Most people were misled by the pot size information. Thanks.
You're welcome.
Thank you, finally a plain talking,informative tutorial about care for nobiles without the fancy techniques and confusing information you tend to get.
Just think of them as 'seasonal' - they grow in the growing season and they rest when it's not. And their Winters are cooler (well, yes), brighter (the leaves have fallen from the trees), and quite dry (wet/dry seasons).
Mine are all doing a bit of everything. Not my favourite orchids but people keep buying them as gifts for me!
They always look good in the shops.
Thanks for that video 'Roger!
Great explanation
Thanks.
I love your new grow room! Thanks for the video.
You're welcome.
Thanks for the video
Thank you very much for such an informative video for a novice. Very lovely done, and much appreciated.
You're welcome.
Great video roger..i learned alot❤❤
Thanks.
I love Dendrobium Orchids -
All doing well in cold weather -
new flowers for the spring .
Thanks for the vid, Roger. My biggest dendro. Nobile is getting buds at the moment on every cane there is.... 👍😉 Five big canes (three of them from last year😁) with buds and blooms on a lot of places all over the plant... It's going to be spectacular.... I hope. The feeding I did was every 2 weeks 20-20-20 full soak rainwater. The rest of the year I followed the feeding program that is given us from the "orchideeënhoeve" in Holland. For me, it worked out very well in combination with your tips.
Sounds good.
Amazing presentation as alway. My nobly cain half way up no leafs bottom there a shoot. There’s new growth and there’s are stumps with shoots. I av no glue so I left it in the corner and only water if dried!
This was so, so, informative. Best info I have heard. Lots of my questions answered. Thank you Roger. I have a better idea of how to proceed with my seedlings, out of rest etc. I need 1 more year. Bookmarking and rewatching to take notes to consult in future. Memory is not what it use to be. Heading off to get you a coffe and become a patron. By the way, also love your knowledge on the birds. Heard them sing and saw the feeder. You are settling in at your new place well. : )
Thanks for the support.
Thanks for that Roger, I also love Dendrobiums. Mine are doing ALL the things you mentioned. One of them, ‘Wonderful Purple’ only decided on a short rest after blooming on and off all summer last year despite being treated just like the others. She currently has two flowers on with a lot more buds coming. I did start giving her a trickle as the buds became larger, following your advice. Thank you again 😊
Despite all our efforts, some will just please themselves.
Valuable knowledge , many thanks Roger.
You're welcome.
Thank you for this. I grow a lot of other orchids but I struggle with these ones.
Some of the nobile type hybrids have other types of Dendrobiums incorporated - this can change the way they behave.
I repot all my orchids and Dendrobium -
Lot of flowers in Spring time .
Thanks for sharing your knowledge with us.
You're welcome.
Thank you for your conflicting information on the canes. The bottom line is the blooming stem is going to do what and when it wants to do!😊 ❤!
🙋♀️ ,Dendrobium nobile Hamana Lake ' Dream' in this house behaving just as should be. Very exciting times . Lots of buds forming and showing their colors in a pot with more sun exposure. So true, they can handle winter sun very close to window glass. Started light feeding+ more water 2 weeks ago when flower spikes started separating from the cane. Thank you ,Roger for sharing your advice and suggestions on growing Dendrobium nobile. They are fantastic orchid if we get it right.
Most people get some blooms but to get that mass-blooming takes a bit of effort - I think that bright light while resting gives more blooms together.
@@GrowingOrchidswithRoger ❤
Thank you for valuable information. And I'm learning a few tips with my DENDROBIUM
You're welcome.
Thank you for this Roger
You're welcome.
Thank you Roger for valuable information👍 I kept my nobile hybrids shaded in fall, and temperature dropped to about 15 degrees celsius. ( they were in my balcony,) My apollon, formed buds, (3 pieces)in one cane, but its nice to know, that mass blooming its not very common, and it will form buds maybe later in the spring, who knows😊
The mass-producers use hormones and the like to get the mass bloomings.
Thank you for your video Roger, even though I live in the Southern Hemisphere, I can still adapt it to suit our conditions. Lots of useful information that I have not found in books or sites here. Best wishes.
You're welcome.
Excellent advice thank you
You're welcome.
Very informative, thank you.
You're welcome.
Mine is about 4 feet tall and in a pot of garden dirt in a 10 gallon pot in SW Florida. So far so good.
Interesting. My newly acquired Nobile is pushing Keikis. I was hoping they would be blooms, but not yet.
Some say, keeping the plant cooler will stop keikis and some say it's too much feed. I've never really pinned it down.
I really enjoy my nobiles. Wonderful scents. I'm seeing buds on most of mine. My little sweet scent is setting a few buds also. Nothing on my nester though. Thanks for the video.
Den. Nestor is different and should still be resting. Mine usually blooms towards the end of April into May.
Hi Roger: did you do a video on Nobile repotting and the type of medium and pot that you recommend
Any fast-draining media will do and a relatively small pot seems to work best but it does make them 'top-heavy'.
I am very new to orchids (well, I've always had phalaenopsis) A widow in my church sold her late husband's orchid collection, because she was so worried she wasn't caring for them properly. I had no self control, I bought 25 various species. Some are mounted, some are in a hanging pot. I am thankful this video was randomly on my CZcams feed because you seem very knowledgeable!
Some of these orchids seem stressed and have yellowing leaves, some have yellow with brown spotting that is coming from the end of the leaf inward. So I'm mildly panicked - but I like what you said, panicking won't fix anything!
Edit: the one I'm most concerned with is labeled a dendrobium speciosum var curvicaule. It's mammoth - nearly 2' feet in diameter. Some of the lower leaves are yellowing with brown spots and falling off. I have read a little bit and it seems it does that in the fall. But here in central Florida it hasn't felt like fall yet.
Dendrobium speciosum can be difficult to grow as in the wild it grows on rocks in open woodlands where there is a constant air-flow. It will need a dry Winter rest too.
Great video on nobiles Roger👍I have many nobiles in my collection and because I live in Japan they get hazy humid summers and sunny cold winters. I mean Roger that Japan has winters where the sky hasn't a cloud and at night it can freeze. It's like living in three different climates here. Anyway, I learnt some new things listening Roger and thanks🙏💖
You're welcome.
Thank you I love the way you explain things 👍
I started my orchid collection last year, all outside in my harden in Los Angeles. I have 4 Dundrobiums & so far no nobbing sign in any of them. I did all my homework, so not sure what really to do 🤔
Dendrobium nobile are my new favorite orchids. And Cattleyas, but those get so unruly! 🤣
There are some good small/medium sized Cattleya types around.
I have a vigorous species. I have put it on a top shelf and ignored it since the nubbins have appeared. Every time I see it and want to water/feed it, I have to tell myself don't do it! Last year the nubbins turned into keikis. If they still turn into keikis, I will blame it on too much summer sun😂 and give it more of a summer/winter differential. But I think until the appropriate hormones are released by the plant the meristem cells can be either or. I would assume the default would be keikis but I don't know. There are a few good online articles (with references) on inflorescence meristem. Some are easier to read then others.
The only one I've had that produced keikis no matter what I did was the Stardust 'Firebird'. It did bloom as well but always looked a mess with growths all over the place.
we have blue backed, red breasted nuthatches here too. (Calgary) You are making me want to give dendrobiums a try :)
Thank you for that, answers a lot of my questions about my misbehaving plant! Mine shot up new growth in the fall in my greenhouse, so I've just been growing it under lights in the house and still watering and feeding a bit. Any tips on preventing the fall growth?
Perhaps get it into a cooler area a bit earlier?
@@GrowingOrchidswithRoger I was thinking the same thing, I'll find somewhere cool and bright so it thinks its winter. Our summers here are very dry, so I was also thinking maybe that the increasing autumn humidity could have stimulated growth too?

Hello Roger, thank you for your knowledge in this field. I am looking for help with one of my nobles, it just doesn't want to do anything, it not growing, and it looks very sad. I don't know what to do to bring it back to health. I wish I could send you a photo, maybe you can give me some advice.
Many Dendrobiums have a period when nothing is happening. Try moving it to a different place?
We have been given one of these for Christmas , it is absolutely covered in blooms now January , what do we do all canes are blooming . 20:55
Keep it lightly watered to support the blooms - it's been 'forced' into bloom. Sometime soon - probably as the blooms start to fade, you should get new canes starting. This is the time to start feeding and watering more frequently.
Very informative and thank you. Our nuthatches were out and about in snowy Michigan but we have the white breasted. Will see if I can find red breasted which are not as common here.
We only have one type.
Great video! Also love all the bird commentary/updates. My nobile (Red Emperor hybrid) is blooming nicely right now, but the base of each pair of blooms has also put out between 2-4 aerial roots that are elongating like mad. Should it do that or is it "misbehaving"?
Some bloom spikes do produce roots. It's 'genetic confusion' where the plant can't make it's mind up between blooms and keikis.
Envious! I have a Red Emperor but it's a seedling still I believe. May need 1 more year for it to bloom. Did get an ice taller and fat cane last year. I still have it rest after hearing Roger's comments.
I have a Dendrobium nobile hybrid (Spring dream "Apollon") already in full bloom with a good amount of flowers. It grows under LED lights and receive the same amount of light all year round. For 3-4 weeks in Nov/Dec, it receives just a sprinkle of water on the surface of the pot every 10 days and no fertilizer. The temperature is around 72 F during the day and 60 F at night. I’m surprised how great it does…
When I had that one, it was always a reliable bloomer.
Thank you, Roger. I guess my Nobile is needing some extra feeding. It's been growing two keikis and a new growth for months but no roots yet!
Personally, unless I specifically need another plant, I take keikis off the canes.
Need to keep that thought in mind. I have to look at it as "increase work load" or takes up space.
On the Den that Marius gave back to you, there appears to be nubbins on the tall thin cane near the top. I noticed several times when you were speaking. Nuthatch are lovely birds. If you had a regular tree then they would be running up and down the tree looking for suet like the chichadees eat. I would love to have a Nobile orchid in my collection It would work in the winter for me. I would need to see if I can find an orchid nursery where I can get one. Anyways thank you for sharing and have a great day.
The nobile hybrids are often sold in supermarkets and DIY stores plus garden centres in the UK.
My nobiles are then very missbihaved. They continue to grow psb in the winter. The psb they start to grow don't finish up in autumn. They bloom whenever they want. So if they still grow, I just don't stop to provide water and fertilizer. But in winter I do provide less of it, as the growth is slower
Some just do as they please but as long as they bloom for us, the time of year is less important.
Thank you, Roger, for this great and informative video! My Den. kingianum has bloomed while growing a new cane, which did not grow its terminal leaf, and it seems it just will not do it. It took a bit over a month of rest, now it is growing two new canes and it also started growing a keiki from the apex of an old cane. I was surprised!
I recently bought a Den. lodigesii on line. It is potted in bark and is a total mess of keikis, but virtually no new growths. I wonder if I should mount it.
My other Dendrobiums are doing fine. It is summer in Argentina right now, they are all growing new canes and roots, so I am feeding them.
Happy growing! 🌸☀️
Den. kingianum mainly grows in rocky places and some of those places get quite cold in winter and remain almost totally dry. lodigesii naturally grows keikis and they weigh the canes down so they can take root. This habit can form quite large 'mats'. I have mine mounted, but in the growing season it lies flat rather than being hung up with the others.
@@GrowingOrchidswithRoger Thank you, Roger, for this interesting information. I am still thinking what to do with my lodigesii. I might try mounting it and see how it does. Cheers!
I’m very very new to orchids, I have 2 nobiles that were in full flower when I got them. Last years flowers appear to producing new growth. Since October they’ve been in well lit unheated porch. They both look very healthy. Can I ask if old flowers usually start growing again? Thank you 👍
Each leaf grows from a node. The plant can produce buds from the other side of each node but only once.
Good game but I have only vague recollection of them.
Thanks.
😊👍
I have just bought the dendrobium noble and is in flowers what do I need to do with it
Hi Roger, is the hairy dendrobin known as nobily. My hairy plant is called Dawm Maree.
Dawn Marie is a 'black-hair' type they come into the Formosae section.
I've had one plant that was my Mom's. It was CONSTANTLY blooming!. We live in Florida so we have high rain/humidity/sun, The plant got so big (some stocks were 3 Ft. long and pulling my pot over!), I finally divided it and ended up with at least 6 plants. They also continued blooming! I had to cut (sorry!) the long stalks that were bare of leaves in order to repot. Guilty? YES. But I now have about 6 mini plants that are all producing small growths. Will those cut stalks produce any new growth?
can you explain kiki's and Vander bucket? I've had success with the big most common without any fuss. But not having been fed or replanted
Keikis can be researched via a google search and the Vanda bucket hasn't been used for a long time. This is an older vid.
Guess mine are both misbehaving. The no ID white started developing nubbins in October while working on a couple of new growths. It had a huge flush in November/December and is now back to growing. The named one decided to work on that new growth which might eventually mature…maybe. Same care for both - treat bag of osmocote and water can while outside, very brief wave under the shower now,.
Some seem to just please themselves no matter what we do.
I have one and I got 3 shots come out of the main stam do I cut them and re pot?
😊👍😊
Hi Roger,
I wish I could re-like a video. I just got 2 new dendrobiums for Valentines Day…I’m pretty sure they are nobilies. I killed the first - no dry rest. Please explain the “pushing-on” verbiage. I’ve heard it from several veteran orchid growers…but it’s still unclear. I watered when there was still leaves pushing on at the top - ended up with a dead plant. I grow in the Pacific Northwest- but the dry area and in a “sunroom”. I struggle with keeping my humidity above 30% in my growspace. I do have much cooler spots in my house I can install grow lights in, to give the bright light but cooler method (60 degrees F).
I’d appreciate an update on these 3 plants.
Thanks,
Becky
The expression is normally used for heavier feed levels and more often when a plant is in full vegetive growth mode. But great care has to be taken depending on pot size and media type/age. In a pot that holds moisture for quite a while, the frequency would be far less. In a smaller pot especially with higher temps., the media would dry quickly and need watering much more often. The media should be heading towards dry but never quite getting there.
How do you water your nobile that grows in the wood trunk like what you are showing?
The video explains watering ?
What happens when all the leaves fall of but have new groth coming up from the botton?
If there is growth, you should feed and water.
Thanks Roger! Wouldn't feeding and watering apply to all orchids i.e. those creating new nubs, or with new buds? I have an in-spike phal with buds but don't know if I should feed it? Since I lost my first dendrobium through not watering enough, thinking it was to be kept dry, I have been reluctant to get another. Though I did get a different type recently, which you advised me is a Latouria and so far, so good. Now that I understand their care I shall look for a d. nobile.I I am encouraged by your explanations of care and thank you for being so generous with your knowledge! I see that you've put bird feeder into the garden!
During March/April, the stores are often full of them.
@@GrowingOrchidswithRoger Thanks for that! But I go to Sunset Valley Orchids (Fred Clark) for Dendrobiums y Catasetums. They sell Aussie Dendrobiums
and breed catasetums.
Excellent reputation. They are in California. I know of some really good growers that I buy from online as I have no car now.
dear mr. Roger ,sorry for may english, I have one white dend. 3 years old full of flowers , but I boght one orange color this year and after blooming on the 4 cains grows many keikis. I know that is not so good. Please can you tell me what to do the best . Iwant a bloom and a next year.Thank you verry much,from Croatia.
If it's bright orange, then it is probably Dendrobium Stardust 'Firebird'. This plant is a notorious keiki machine. I have yet to find anyone who has the solution to stop it but some say, keeping it cool helps.
@@GrowingOrchidswithRoger thank you for your answer mr. Roger. Did she make a flowers next year. Do you take of a keikis when they make a good roots.
I have a dendrobium. It bloomed once has some tiny canes which bear kikis, no leaves on it. Whats wrong with it?
Without seeing it and knowing what type it is - impossible to say.
Hi roger. Great detailed explanations. I just purchased a Dendrobium pendulum. Could you please advise on its care. There is hardly anything available on the web for this particular deciduous Dendrobium. Thank you.
Sorry about the ads., but this is probably the most detailed info in one place for this orchid : travaldo.blogspot.com/2019/06/dendrobium-pendulum-care-and-culture.html
@@GrowingOrchidswithRoger thank you. I did see that article and was discouraged in seeing that it’s hard to cultivate. Also, that it molds after 3 years. Any suggestions as I haven’t any experience with Dendrobiums at all.
I just bought a Dendrobium nobile and it has such a tight rootball I could hardly get any of the old potting medium out. What is most likely to help it, leaving the packed roots and putting it in a bigger pot, or being rough enough with it to get root pruning done?
Personally, I wouldn't repot until there are new roots growing - that way, any damage is limited as the old roots will be replaced into new media.
Also what is correct potting medium for nobles mine are in bark compost?
There is no 'correct' media for nobile types - but something like a mix of small/medium bark will do.
I am new to your channel, my dendrobium after a few days of cold weather and even after shielding them from these conditions, many of its leaves are yellowing and falling. Help! They receive morning light. I have been reading that I should hold back some of the watering. Is this correct?
I can't give advice unless I know the whole environment.
Hi Roger. I’m one who has struggled with Noble types. I am in Sydney Australia 🇦🇺 and have had my nobile in full 🌞. Will now move them inside in no direct sun and more shaded. Wish me luck. Thanks again for a very informative video. Also can I cut the cane which has no leaves?
The nobile types don't need bright light in the growing season - just during the Winter rest period. Old canes still provide some support for the overall plant as they store nutrients but too many leafless canes will drain the plant.
Do nobilies like to be slightly pot bound as mine I think might be in too large pots,but one is a big plant the other has fewer canes and a couple really dry and shrivelled canes should I cut them,also have not had flowers on either of them,I wandering if I should repot totally in bark?
Nobile types are ok in larger pots but great care has to be taken with watering. To bloom, they need to be cooler and brighter in Winter than they were in Summer with very little water and no feed.
My canes do not grow upward. Is that the way they’re supposed to grow, or do they need to be propped up?
Most Den. nobile types are upright growers, but some do bend over or even hang down - it depends what went into the 'mix' of the hybrid.
Great video! I have a dendrobium orchid that I bought almost two years ago. It has not bloomed since. It has produced many new canes and leaves but not sure why it won't bloom. I do let it dry out quite a bit in between waterings. Any ideas how to get it to bloom?
Probably more light.
Same story here. Buds, blooms and keikies and a new growth on the same plant and all on older canes. The new canes don't so anything
As long as there are some blooms.
@@GrowingOrchidswithRoger I keep finding buds 😁
For a change I think I agree with you Roger. I think the decision has been made long before you see the bud. Admittedly that is just my guess. It is also been said that you can't raise baby guppy fish with the parents because it somehow stunts their growth and you can't raise them in a 55-gallon tank it's too big they can't find the food. Well I'm doing both, I'm happy with the growth and as they do grow they seem to be finding the food.
I think people get an idea in their head and start stating it as fact before bothering to find out if it is fact backed or not.
Blimey - an agreement. Now all you have to do is learn to spell my name.
@@GrowingOrchidswithRoger Nope voice recognition I just missed it.
Very, very usefull talk for me. I have 4 nobiles mounted on trees in the garden where they are for 4 years now, nubbins showing on some, but as this year´s rain season has been poor, their roots seem very very dry. Should I water the roots only? Should I wait for the rain to come later on? Thanks for any advice, if possible.
This is in south europe, Lisbon - Portugal where this winter has been more like a cold spring with blue skies but no rain 😬😬😬
If the canes look as though they are starting to shrivel, then a little water will do no harm.
Should you like slowly give them less water and fertilizer? Would that be a good way if one year they decide to keep growing?
I always water my orchids and Dendrobium.
Dendrobium very easy care - doing well in winter - lot of flowers in Spring.
There are guidelines to get the nobile type hybrids to bloom but many will still produce some blooms without any 'special' treatment.
my dens are out of sync with the seasons my devonianum grows through winter so does my wardianum i thought they were winter resters
There is a lot of confusion between 'drier in Winter' and a true 'Winter rester'. A true Winter rester will come from deciduous forests where there is little rain during those months - plus it gets quite a bit cooler.
Why is it that your orchid a lot of keikes❤
I don't know.
Quit rubbing your nose. It is very distracting.
Cat hair.
Good information.thanks.
You're welcome.
