Most dendrobiums bloom after a winter rest in the spring. I would recommend doing research on your plant, whether it needs a winter rest, etc. im guessing it's probably a den. Nobile since that's what they usually sell in stores. Those will loose leaves in the winter and then you should stop watering until spring, when new shoots come out

Does it have a name tag? if not, maybe you can give us an idea of the type.

Look here all sorts of Dendrobiums

And here Softcane/nobile types of Dendrobium

Also tell us where you are and be aware that most Dendrobiums will have an annual cycle of growing and blooming,

You are talking about D. Nobile. Are you sure ? I was thinking I owned a D. Nobile but after research, it is not.

The common type of Den flowers you see in stores (blue den) is the type with canes that grow 1 or 2 stem on top. Those are not even the same type of culture as D Nobile. So you better know the type of culture and details as Arthur told you. Good luck.

what kind of orchid is a

Dendrobium kingianum

What happened to Sicily Paul?

Mickey, how do you know which orchid he was talking about?

Jane

no idea

wish this site emailed you when you got responses

Here is a useful link to Dendrobium Sections.

Dendrobium sections

I dont know whether my dendrobiums are Den. Nobile. I am attaching photos. In one photo please notice, the stem for the blooms but no flowers. This one I bought from a separate stall. All others from another stall of an Exibition.

Please suggest what to do for blooming. I am a begineer

thank you for the site very useful , I bookmarked it

Sicily, where is your photo?

Jane

Jane, I am attaching the photos again, see the marked bloom stems but no flowers

Both are warm growing "Hard Cane Phal. Type" Dendrobiums. Wherever you are, you have to provide growing conditions like the climate Southern Florida, Hawaii, Tropical South East Asia etc. etc.

The spent little flowering stems will never flower again so you might as well cut them off. Orchid 2 looks like it has a new flowering stem starting. Sometimes blooms will come from the top of older canes, so try and keep those older canes as long as possible.

"Micro-Climate, Zone 10b Sydney, Australia" is stuck next to my name because these days with the University of google, you can easily look up the Climate details.

To get fine tuned advice you need to tell people where you are in the world. You could be in Alaska, Florida, Sicily ???????

It appears on photo 2 you may have spider mites. Check the underside of the leaves that are a little yellow with a magnifying glass. They are tiny.

Where are you??

I am in India (Kerala) and the plants are in moderate warm on eastern side window. What to do with Spider mites?. Need to wipe it off or use any insecticides?

Or Thrips. I'm having a terrible time with them destroying the buds on my hard canes. All my buds are sucked out. No flowers. I'm ready to toss them but they are one of my favorites. I have so many and love the large sprays of flowers, but the Thrips kill the buds just as they are starting to form.

Trying to find sprays which are not too environmentally unfriendly to deal with them. So far, no luck. Very frustrating as these dends only flower once a year.

Sicily, you need to tell us where you are!

Jane

I am in India, Kerala. Some what warm and I placed my plants, hangining in the eastern side. For the spider mites, do I wipe it off or need to use any pesticides for that. What should be the watering pattern in hot days, need watering in morning and evening? Please advice

neem works good , or you can keep washing it down , spider mites hate dry conditions

Mickymantle I think, meant to say that they love dry conditions on the underside of leaves.

The standard advice is to water in the morning so the plants dry a bit during the day.

I have hard cane types and they bloom in winter here in N.Y.

They did so well for me in NY. Florida is different. I lose all the buds. Lots of empty spikes. Not sure if they are not being kept watered enough or something else.

I'm about to give up on them in Florida.

Jane

Interesting Jane. I never saw empty spikes unless the buds, alfter almost complete growth, turn yellow and fall off. To much water ....... I guess.

I have 2 species of hard canes Dendro. One is doing well, the other not. I learned that they need a month with no water during the growth of the Spikes, between the end of the growth of the new canes and bloom time. Then you can start water, but not as much as summertime. Am I right ? I am trying this now and it seems to do well so far.

with the other one (Celadon and red wine), it's complicated because they seem to keep growing. The canes are still short. They feel they are in july. I try to stop them in order to restart them in the spring in the right time. If I can. I like the challange ..

hours of fun !

There are all sorts of Dendrobiums. Here is the link again showing the variety of types.

Unless you know where the ancestors came from etc. etc it is all a guess. Cannot find a hybrid Den called Celadon. Many types of Den are easy here. Not so the ones with Dendrobium Phalaenopsis as an ancestor. I'm about to give up on them.

all sorts of Dendrobium

Jane, before you give up try s/h (semi hydro)!

I had lots of plants in it years ago when I was still living in Germany but I never tried orchids. Then a few month ago we had a speaker at the orchid society and I bought some of the containers he had on offer (I made some of my own since, basically any big enough, tall, plastic food container in which you drill two holes about 1 ½ - 2 inches from the bottom to create a water reservoir). I have a L. anceps growing tons of new roots in s/h and three Dens that did not bother to grow new shoots first but are in spike/ bloom (since transferred)!

Arthur, : Celadon And Red Wine is a name I've found :

http://www.beautifulorchids.com/orchids/orchids_potted/dendrobium/dendrobium_celadon_redwine.html

but I have found another one that can be better :

Dend. Madam Vipa Is this a better name ?

I recently found out that the medium was old and the roots were almost dead. So, I repot it and the leaves turn to be nice and hard again like in a miracle, the day alter. I use fine fur bark for the first time. I still hope for good results.

At least we know that "Celadon and Red Wine" is a warm growing phal type hard-cane hybrid Dendrobium. As for getting the correct name that is just about impossible. Tens of thousands of registered hybrid names.

Passing on culture. I'm giving up trying to grow them, they need more warmth in winter than i can provide, but in a nice centrally heated house with a bit of extra lighting......(centre QC (4b) who knows

Sicily- you should have no trouble growing that type of Dendrobium in Kerala. Mist or spray the roots once a day if there has been no rain. Add a very weak fertilizer to the water while the canes are growing. Treat your spider mites with a mild dish soap solution. And be patient- Dendrobiums won't bloom year 'round; they have a season.
