That is very helpful and thought provoking too !
It reminds me of conversations I had many years ago with the late Laurie Humphries a lovely man who taught me a great deal ; he ran a nursery near Tunbridge Wells (Armstrong & Brown) I used to go and see him and talk for half the day , if I was working in London and had a few hours to spare, usually waiting for a Judge to give me a slot for a five minute appearance or something like that .
At one time he was called in to a big USA orchid nursery as a consultant ; their cattleya seedlings were not growing well. He discovered that they were using growing lights ( almost unknown in Europe at the time, I suppose) and were giving the plants 18 hours per day. He reset them to 12, and the problem was solved.
I ll reset mine to give the better light in the middle of the day .

Hi Geoff
If your oncidiums are looking tired it can only be light levels or fertiliser.Having spoken to you at Bournemouth and knowing you have a very extensive knowledge of fertiliser I would not think that you are giving your plants to much nitrogen at this time of year(this can cause floppy sad plants).I would suspect that the problem is to do with light levels.If you upset the plants metabolism by giving extra light at the beginning or end of the day your plants become confused and do not know how to respond.When I used to bring in stock plants of bedding plants like geraniums in the autumn and gave them extra light they suffered but when I used to let them slow down in natural daylight and let them sleep they all was fine. As the days extended from say mid January I then gave them extra light.The plants were beginning to awaken from treir winter sleep and they responded to this extra light with great enthusiam. All plants need a break and I think that the extra light that you are giving your plants now is the problem.Hopes this helps.I wish I could have been at Bournemouth for your talk on Vandas but alas my wife has a back problem which is very painful.
Regards
Brian

All my oncidiums etc. in hydroculture are looking a bit tired ; I think I am going to give them a tonic in the form of a spray with Epsom Salts ( Mag Sulphate) plus some Superthrive, then reset the sun lamps so as to give 6 hours continuous instead of 3 morning and 3 night, just for a couple of months. See what happens.
Anyone got any better ideas ?,

Please could someone give me a clue as to the genera of the orchids
in the attached pics? I should know them but the little grey cells
seem to have gone on strike...

Hi Tricia

051 is a Coelogyne − possibly Coelogyne Memoria William Micholitz
037 − Papillionanthe teres
036 − Degarmoara Winter Wonderland 'White Fairy' (looks like and it's very
widely available)
035 − I'd like to see more of the plant habit and leaves .... but .... the
flower has the shape of a Trichopilia ... could also be a complex cattleya
multigeneric. THe flowers look like BLC Copper Queen whish is out now in my
greenhouse.

Some ideas to be going on with .....

Thanks, Peter. I thought that's what it is, but sadly the piece you
gave me didn't survive − I don't think it liked my greenhouse − so
couldn't be sure. I seem to be better with Trichopilias nowadays and
might try marginata again as it is a lovely thing.

Thanks, Andy. The photos are part of a set taken by someone visiting
the Singapore Botanic Gardens, and I wasn't given any
identifications.

Your suggestions are most helpful − as you will no doubt have seen,
Peter F has positively identified 035 as Trichopilia marginata.

Oh ,never mind, can't win them all. I must admit my favourite orchid
species of all time is Trichopilia suavis. I bought a nice piece
from Laurence Hobbs.

My trial at growing Pleiones has not worked very well. Mostly my
fault but some of the ones coming from the far east were not in a
very good condition to start with. I tried the normal fine bark,
perlite and chopped NZ Sphagnum moss. The better bulbs grew ok but
not great.

The ones that grew at a amazing speed and had leaves as big as a
Lycaste, we're grown in straight John Inness No.3. New large bulbs
and plenty of bulbils. I water gently until new roots were growing
and then watered fairly heavily. They are resting now.

For some reason all this set of message arrived together, so I m a bit late joining in.

The only one I d question is the Coelogyne, I think my Mem Wm Micholitz is rather fuller and rounder than the flower seen here. I have searched my databases ( sounds very grand and organised ! if only .... but I did come up with the pic attached from my web-pages , circa 1999 !

All (?) the Wm Micholitz s I have ever seen are probably propagations of the AM form, and the cross is so old it predates mass production, so I think that the one shown is either one of the parents say mooreana or perhaps not here seen at its best.

But looking at Orchidwiz, the ones (Micholitz) illustrated there are just as poor....(!)

Hi Andy,

I can see no reason from here why that should be − I've checked the
database and your address is as it should be. Could it be that your
Windows Mail sees them as a duplicates and discards them?

Thanks, Geoff. Actually, for my purposes it's enough that it is a
Coelogyne. For some reason I kept staring at it and thinking it was a
Dendrobium... The men in white jackets are on their way.

I'm not convinced the Papilionanthe is teres − or at least not
purely. It bears more of a resemblance to hookeriana in all the
pictures I have found (now I know what to look for!) so maybe it's a
cross between the two.

Anyhow, I don't really need to be too specific, the photos are some
of many which have been submitted for a photographic competition.
Only five will make it through the first stage, but I have to give
each one a name slightly more descriptive than just 'Orchid'!

Thanks to all who have pointed me in the right direction,

Tricia

Geoff,
I am inclined to agree that the Coelogyne is Micholitz. The only other Coel hybrid that is similar is Louis Forget. Micholitz parents are speciosa x mooreana, both being common in many greenhouses now. As you know speciosa has no fidelity and will readily cross with most other Coels especially if it is the seed parent. I think that it has been remade a number of times; I do it periodically for fun.

... so I took a few photos.

Restrepia trichoglossa − I just noticed how splendid this is looking − a little bit of sun caught it just right. Actually that is one of the reasons why I like miniatures − they can blend in and then suddenly appear with a good show. This was just a couple of leaves when I put it on this mount 5 years ago. I grow this one cool but one of my friends grows it successfully in warm conditions.

Restrepia guttulata Pat Hill. I have several clones of R guttulata including some named ones like this one. It is a splendid species − the flowers are more than twice the size of the R trichoglossa. I have only had this one since last year but I am looking forward to it getting large.

Prosthechea radiata At least that's what I know it as − it's done the rounds taxonomically speaking. A fantastic plant for every collection if you can give it a bit of heat.

I have 3 Laelias in flower at the moment − L anceps is too big to get out and photograph but the others:

Laelia gouldiana This is a very good clone − the colour is very deep and the flower shape good. I bought it years ago as a little thing in urgent need of tlc at our orchid society.

Laelia albida Another favourite of mine − I need to remount it this year as the mount is rotting away − thought the plant does not seem to mind. I grew this from a flask − I think about 7 years ago.

Epidendrum tridactylum I have only got to know this recently. Apparently grows in many different conditions. Lovely thing....

By the way Tricia re my postings not coming back when you send them out − I have checked and I see they are on my email provider's web mail server. I don't know what the issue is but I think you are right and it is something at this end.

Good to see your pics Andy. If the group is to survive , some others have to contribute now and then !

My collection and growing systems are all in a state of change , in order to try and get the plants on the bench happy ( again) despite the second tier of plants above them mostly the smaller vandaceous ones − being kept (very) happy by (very) frequent spraying.. This means repotting the hydroculture oncids etc out of Perlite and into Hydroleca ( baked clay pebbles ) and moving all of the cattleyas into that media. First indications are good, but until I get back to producing really good growths and flowers, it is too early to be sure. If only I could eliminate the scale from the cattleyas ; I have decided to ignore what Bayer say about Provado ( 3 apps per annum max) and do a routine spray monthly but what to use as an alternative to Provado that is the question..

I have today just finished repotting everything in my growing cabinet ( a two West & E. dew-point cabinet) which I do every three months or so , and most will go into the greenhouse after Xmas, probably February , leaving the cabinet empty. I am thinking of having a go at some oxyglossum dendrobiums, and growing them in that cabinet ( 100% humidity) and not simply raising them there.

I am interested in your laelia on mounts ; I did poorly on mounts most of my life , probably because I was always away too much ; but now that my wife can t travel very far, we are taking shorter holidays and I am doing better ; I have a C.loddigesii now up to half a dozen flowering growths on bark, etc ; the holiday arranged for the near future is to celebrate my big 8 birthday ( and I fear I shall be bored stiff on a cruise liner, visiting places I have been to before, many times, for week after week) but I think its the last such long holiday I/we shall take. But getting back to the laelias, I will look out for an albida to try. I am just about to write to Dick Warren about the oxyglossums I ll see what he can offer. ...

Hello Geoff,

I was given a couple of Dendrobium keikis last year and when I got home and unwrapped them they were covered in scale. I submerged them in a strong solution of Selgene Ultra for an hour and the scale washed off under the tap. I don t remember the strength but it was something like 60 cc in a pint of warm water. They never came back.
Why not try a couple of plants you are moving into hydro culture. Even the delicate leaves showed no damage. Cattleya leaves are much more robust.

David, I am spraying with Selgiene , monthly, now but my comments were prompted by looking at three different gallon bottles of Selgiene I have and realising that they are different strengths !. ( Selgiene Super, Selgiene with no added comments, and Selgiene Food grade.....I have also bought some Citrox, which can be used quite strong without harming plants (sic) . And I have done three Provadao sprays in the last 7 or 8 weeks and even so, tieng up a flower spike, my eye was caught by a large mass of male scale on the underside of a leaf, quite newly hatched or whatever it is that they do. Quite depressing !.

Geoff, I stopped using Provado many years ago to combat scale. I use the Joh Blowers and Wyld Coutr system -methylated spirit. Scale on thick fleshy rooted orchidsgo down into the potting mesdium so they are taken out of the pot and all medium removed andbinned.The plant is then dunked into methylated spirit for a few minutesand then put aside to dry for an hour. The scale can then bewashed off with water.
The meths has dissolved the wax coating on the pest and dehydrated the pest to death.Do not leave the roots inh meths too long asit also dehydrates them.
This is a hell of a job if you havea lot. It took us a week to clear 500 Cymbidiums donated to us at The Living Rainforest at WYLD Court
Regares.

Exactly so Dennis I have 500 catts....
I have been using meths ( and a stiff paint brush to apply) as a spot treatment on everything found, between sprayings, for a couple of years, but still they keep coming. As youi say they are in the compost, on the underside of the rhizome, on the roots etc. So I have repotted all of them, cleaning as I went, and put them into hydroleca (baked clay pebbles) that was last week and the week before it was just yesterday or thereabouts I found a fresh mass of the male insects...which adds up the reason for my despair, and I suppose, eventually, getting rid of all my cattleyas. They are no problem on anything else.

To all with scale problems,
If you go into your garden centre you should find a product from "Bayer" called Greenfly killer.This has only been available since the summer and it is the same product as a commercially available product called "Decis"This is a contact spray and should be used at regular intervals.Those of you withinternet intelligence should look under the agrochemical active ingredient "deltamethrin".
Hope this helps
Brian
