Dendrobium question

Question:

Greetings,      I just purchased a Dendrobium Jasmine Curtis x Walter Oumae. In the orchid cultivation book I have it lists 6 different major cultural groups; all with different care instructions. If anyone could help me out a bit with cultural techniques and possibly parentage lines I would be grateful. Also, is there is a web page or a book that I could look up hybrids in. I imagine it would be a mammoth publication. Thanks, Scott Mcphee

Scott, yes it would! Baker & Baker have a semi-huge book on Dendrobiums; and we are adding a Dendro Culture next at The Orchids ReSource:         http://www.execpc.com/~botana/orchids.html I’ll send you a li’l culture guide that will help for now! -Bob Goebel BOTANA Orchid Books & Art

Scott, Be aware though that the Baker’s book is strictly species.. -Rod- Venger’s Orchids Website http://www.vengers.com/

Response:

This dendrobium is in the phalaenopsis group. The cross has not been registered in the latest Wildcatt Orchid Data. I grow my phalaenopsis type about like cats- with a little more lite, more water, and either a so-called balanced or a low N ratio fertilizer. They are watered and fed the entire year.

Scott,   A good place to start would be Venger’s. They have a service at their site for tracing parentage of orchids. I’ve used it before, and it works great. This would at least point you in the right direction as far as cultural req.   Go to, http//www.vengers.com  Then look for Sander’s searches. sam — Spouse Stifled Orchid Nut       – S.S.O.N –

Hi I’ve got a couple of dendrobium about 12" high.  I bought it when it was flowering a couple months back but now it’s losing it’s leaves. They turn yellow and drop off one by one.  The stalk remains firm and I was wondering if it’s dying or if it’s just going dormant (it’s rather cold nowadays 50 – 65 degrees).  Anyone knows what might cause the leaves to turn yellow and fall off?  too much water?  too little?  not enough sun?  too much?  too cold?  help! 3 stalks per pot.  Large stalks have leaves.  Small stalks lost all of their leaves but remain firm and appear hydrated (not dessicated). Roots are white and firm.  Will they regrow come spring? Reply via mail if possible please. Thanks, Norm.

Norm, Without knowing which Den we’re talking about, I’ll just hazard two guesses. One, most probable, is that the roots have rotted away. Two, considering the temps, it may be going dormant. You should burrow down into the pot and see what the roots look like. -Rod- Venger’s Orchids Website http://www.vengers.com/

Response:

I would say that it’s just the deciduous aspect of the plant doing its thing. If the plant is otherwise healthy – I wouldn’t worry about it.  They want to be kept well on the dry side during the months of November – January you can resume a gradual increase in the watering in February.

Response:

I was given two orchids that hav dendrobium tags on them about two months ago. One of the two is larger, with about 4 stems.  One recently began to have a similar problem- leaves turning yellow and dropping off.  This same stem also put out about six buds and now two have opened into blooms.  The flowers are about 1 inch top to bottom, white with a fuschia color in the center. I am new to orchids – does this sound like a dendrobium flower?? Also, is the yellowing and losing of leaves normal. BTW – I live in Virginia where we had been having cooler temperatures.  The orchids are kept in a window box that gets good sunlight (at least 6 hours) and stays over 65 degrees all the time.  We also get pretty high humidity here year round. I repotted the two orchids in a bark mixture and have been spraying them with a light mist from a spray bottle every day or so. Any comments or suggestions are welcome.  I am happy I found this site! Regards, Bill

Response:

Many dendrobiums will drop leaves in the winter, don’t wory and don’t fertilize yet. only mist occasionally.

Response:

Will a dendrobium rebloom if the spike is cut back after blooming in the same method as suggested for Phals? (Above the last node before the first flower?) Any other species this will work on?

Response:

No, not from the remaining growth . . . I grew the evergreen cane-type (which is confusingly referred to by a species’ name: Dendrobium phalaenopsis!) and since we grew for cut-flowers we weren’t leaving ‘em on the plant for too long (flowers formed and open about 2/3 of the way "up") and the ones we cut seemed to develop new spikes FROM THE AXIL sooner than canes which hadn’t produced . . . or canes where we left the flowers on (to keep the green-house attractive).  I’ve grown hundreds of dendro species over the years (all types) and only have seen this phenom onthe "evergreen cane" type.          Bob,   BOTANA ORCHID BOOKS

Not in my experince.   — Archie Green, Wacahoota Orchids  See our Web Listing at http://www.wacahoota.com

No.  An old Dendrobium cane will often send out new spikes during the next blooming season, but I have never seen an old spike branch and rebloom like a Phal spike. Gary
