Geoff, You cannot go wrong with a few cuthbertsonii's, and all different colours. Pink, red, yellow, orange, and some bicolours and a white if you can get it. I got my first RHS award for a Dendrobium cuthbertsonii and made it on the front of The Orchid Review. 1988, I think it was. Dick Warren said it was the first RHS award for a cuthbertsonii.
Edinburgh Botanical Gardens wrote a booklet on the section oxyglossum of Dendrobium.
A really good section on cuthbertsonii. Dick also has other species from section oxyglossum.
There are some good cd's from Leiden University on orchids from PNG. Not cheap but well worth the cost. I grew mine mounted on lumps of Osmunda fibre, which had been sterilised in a pressure cooker first. I lost half of my orchids from a contaminated batch of Osmunda. Purple rhizome rot. Or I also used chunks of coarse tree-fern fibre.
Good luck if you give them a go. Flowers can last for six months.

Dennis and Geoff,
Imidachloprid formulations seem effective on scale only when used on occasion, but are not able to eradicate. Anymore, I only use spirits for cleaning and light incipient infestations. This past summer I broke down and purchased a small bottle of dinotefuran, the greenhouse formulation sold over here as Safari. Through the past few years it became the latest fad pesticide for orchids. Two sprays and I have not found a live Boiduval scale since. Experience indicates that Safari is one of if not the the safest and most effective scale insecticide. If it is available in the UK, I recommend its use.

I have used Decis in the past, and did not think it very effective ;the concentrate is available from LBS probably under that name ( the label has got a bit soggy and unreadable in the greenhouse ) . I recall that I had to buy a quite expensive two litres to get it. But the usage rate is 7ml per 10 litres of water, so 2 litres of concentrate will last out my lifetime and that of my successors I should think, even with a big greenhouse.

I recall also, that I went into the manufacturers web-sites on the Bayer product (Provado) and the Decis one ( Certis) and both should not simply be diluted and used, just like that ; the pH of the dilution water is important but I forget the details and can t find them now ( Decis in the concentrate has a pH in the range 2.0 4.0 ! ) and so is the ambient temperature at the time of spraying ; add to that the advice not to spray when the plants are in sunshine, and it becomes very difficult indeed to get ideal conditions for a good hit .

My recollection is that I needed a warm muggy day, overcast, temperature in the greenhouse 25 degrees plus.... and I ended up then, and now, thinking that there must be easier hobbies , how about philately.....

Subject: Use of meths as spot treatment for scale etc.
Date: Thu, 08 Dec 2011 10:00

I just wanted to pick up on this point ; I do use the method, but I dilute 50:50 with water.

Meths is too strong to use on thin-leaved plants without risk of cell damage , although its OK on say cattleyas.

This is why American sources say 'use rubbing alcohol” – although you would get funny looks if you asked for that in Boots , I think !. ( especially, perhaps in Scotland ! )

What is meant is ethyl alcohol rather than methyl alcohol. I did use for that for a time, but during some recent security bomb scare, when the terrorists were using hydrogen peroxide as part of some process for making bombs, my local pharmacy said that they were unable to get Ethyl alcohol and I I assumed that they used that too....

But don’t use straight meths on odonts for example – the leaves go a darker green where the cells are ruptured.

Subject: three Paphs
Date: Thu, 08 Dec 2011 17:30

Its coming to the season for complex paphs ; the whites are first , then
the others, although some which are technically not considered as
complex, but rather as Maudiae types, extend this season at both ends.
Valwin x In-Charm White is perhaps technically a white, and you can see the
niveum lip/pouch here – small and petite, and shaped a little
like some kind of song-bird's egg. The white rather heavily
overlaid
with red from the Valwin. but still a white underneath it all. White
paphs of course never are white anyway !.

The British Bulldog cross is very pleasing, such a rounded shape, if the
Committee ever awarded a complex paph nowadays ( I don't think
they would, whatever it looked like) surely this would be worth an
AM.But I am not getting up at 5 in the morning and spending a hundred
quid on a ticket ( rush-hour, no cheap day returns) plus my lunch and a
couple of taxis just to be disappointed.

Miracle is an oldie ; Sanders registration in 1935 , and I think this
clone was awarded in the early post-war years. My plant did not quite
make it to flower last year, but this year has had two flowers on
different growths, a few weeks apart.

Subject: Meths and Scale
Date: Fri, 09 Dec 2011 11:15

I am not a bugologist but I spent about 4 years battling scale at The Living
Rainforest and in my orchids. At home I used many types of insecticides and
scale always returned whereas at the LRF they did not. My hypothes is is that
dunking in a bucket of meths killed the eggs but the insecticides did not touch them.
It is a dangerous procedure and I only used it on heavily infested plants
with good bulbs and thick roots but you have to destroy the eggs. These eggs are impossible to see with the naked eye when they are first laid so a visual inspection is not much good.
Also when a plant has been treated keep it away from untreated plants as scale moves during the night.
Happy Hunting and Regards

Many years ago I saw a plant of this species shown at my first Orchid
Society, and liked it, and looked out for it, but it was 35 years before
I saw the name in a list, and it jogged a memory; the plant that I
bought was a small seedling with three bulbs , the largest not much
bigger than a pea. It was at the time I was first experimenting with
hydroculture, and it turned out that this species loved it. The bulbs
advanced to the size of maltesers, then damsons, and later the largest
is almost Victoria plum size. But it only flowers when pot-bound.
My original plant grew to fill a 9inch pot or thereabouts and had
flowers all the way round, and I took it to London hoping for a CCC, but
it got chilled on the train – the flowers had collapsed by the
time I got into the Committee room. Afterwards I split it up and have
gone through a similar cycle more than once, selling a few plants and
putting others in the raffle as prizes and so on, so it is probably
getting spread around Dorset by this time.
I find I still have two or three plants left , this is the largest of
them. It can be quite pretty, but since the flowers are so close to the
bulbs and the leaves are tall, they easily get swamped and hidden.
The species was at one time re-named as Botriochilus, but has gone back
to being a Coelia now. Flowers are about 3-4cm across btw.

To Geoff
If you have a 2 ltr bottle of decis it must be very old.Decis (Deltamethrin) used to be available to the amateur grower years but became ineffective. It has now been made available again, the strength being the same as the commercial formulation which is probably different to the strenght you used years ago. Having seen some replies to scale problems one must realise that you do not use the same product time and time again.One must alternate sprays and why people spray now is a no no.You spray when the pest is activel and reproducing ,this is your best time to eradicate a pest problem.If you spray all year your pest builds up a resistance to the pesticide.I have sprayed /fogged my greenhouse only twice this year with Decis and my greenhouse is bug free.For example 2 years ago I used a malathion /talstar formulation which is very effective but then I used decis which has a different mode of action.I will use Decis for one more year and then change to another pesticide.Provado commercially has never been meant for scale/mealy and is becomming ineffective in most things it was meant for.Spend 6 pound on some Deltamethrin (Bayer Greenfly Killer)and see what happens

I actually have two one litre bottles of the commercial formulation (Decis Protech) , and maybe I have had it a couple of years, or maybe a bit more but certainly not seven years for example.

As to spraying when they are active, if new pests are found , i.e. ones which were not seen at the last handling of the plants, then they are active , surely ? And my pests are always active ! Bayer say, incidentally, that Provado should not be used more than 3 times a year. Since it takes three sprays at 10-14 day intervals to catch everything at the right stage, that really means only once per year; advice I have tried to follow this year, but that is hopeless.

I hear what you say about Bayer greenfly killer it is not something I would have thought of trying from the name ! But whether one bottle of ready mix (?) is going to be much good to me is another matter with my size of greenhouse and number of plants part from the risk mentioned later in this message !

As to malathion, I would never use that on any orchid, based on previous experience. It is proven to make Phalaenopsis go blind ( the growing point develops a flower spike, and then no more leaves can develop from that growth ; and phalaenopsis do not easily and reliably throw keikis ;Phals are also vandaceous orchids, and what damages one vandaceous orchid would certainly be dangerous to try on another vandaceous orchid , and they represent at least 20%of my collection which leads me to the point of the risk of trying formulations untested on orchids. It could be an expensive experiment !

Incidentally Brian, you won t know this, but Paul (Johnson) , who contributed a message on this subject is an expert on these things. His paper on them may be available on this (Orchid Talk) web-site, and if not I keep a print-out in my papers. But the products he can recommend are not available here in UK.... alas.

This discussion is very timely as during the week I found a nasty infestation on Laelia crispa. Dealing with scale is relentless and sometimes gets me down. I find them from time to time on Catts, Laelias and also on Epidendrums and Dendrobiums. I guess it is part of having a large collection that I therefore do not examine each plant in detail every week.

Anyway I've been to 4 local places today to find some of the chemicals suggested − no joy. Acres of tinsel and tat and very little choice of anything else. It is also very difficult to find the ingredients list on the label. Tiny print tucked away and never obvious or on the front. Do "they" not want us to know what we are using? ( I could get into a rant here!) In the end I bought some Bug Clear Ultra which contains acetamiprid. I've not used this before but it is recommended by the RHS. Has anyone experience of this?

Like you Geoff I could not find a supplier of dinotefuran so if you get any response from your enquiry let us know.....

Are there any greenhouse fumigants still being produced that have any effect of scale?

Acetamiprid is sold under several tradenames, including Assail, Chipco
Tristar, and Pristine RTU, with manufacturers around the globe,
including France. All of the label and application information found
state that acetamiprid is used for various pests on veggies, orchard
crops, and grapes, including wine grapes. The Lecanium and San Jose
Scales were listed on one label, but so far no indication of labeling
for ornamentals or greenhouse use. Other than having a very short
half-life, measured in days, it seems to otherwise be a typical
neonicontoid in terms of safety and hazard − keep away from bees,
fish, small and medium-sized kids, pets, use protective clothing, do
not apply during calm wind or high winds, etc. One label stated
toxicity to "non-target plants", but did not list or otherwise
identify those.

Andy, if you try it off-label, I would bet that many lurkers on this
list would be interested in learning of your observations.

Andy and Geoff et al.,
A bit more poking about and I found a label for acetamiprid registered
under the tradename Tristar, in the U.S., for ornamentals in
greenhouses and there are 12 species of scale listed, and a number of
other insects that are sometimes pests on orchids. Boisduval scale is
not specifically listed, but other hard scales are listed. In the
label is a specific caution about development of resistance which can
be broad-based to many other neonicotinyl insecticides, such as Merit
and Marathon.

http://iaspub.epa.gov/apex/pesticides/f?pPPLS:102:4417955087549510::NO::P102_REG_NUM:8033-22

See the 2006 label. It is a commercial registration for a 70%
formulation. Searching for "Tristar 70 WSP" brings up many web
references. Nippon Soda Co., Ltd owns the registration. Possibly the
formulation is available in the U.K.?

Hi all, I have a quite a collection of pesticides that I use on my cymbidiums, I spray reasonably regularly, more throughout the summer, mostly to keep the red spiders a bay. Now I appreciate that cymbidiums are big tough lumps compared to many of your more delicate and treasured babes, but if it helps your confidence I can say that I have used this Bug Clear Ultra several times this year and see no ill effects on the plants. (I don t spray when the flowers are open) In the past I have also used the concentrate Provado that you dilute yourself, I was told to use it at double strength once a fortnight for the summer month, trusting the person who told me this I did it, he grew some nice clean cymbidiums too..it didn t have any detrimental effect on the plants or their flowering, but now I m a little older and wiser I probably wouldn t follow such advise so blindly again.

I heard a talk by Laurence Hobbs fairly recently and he spoke of using Westland s Bug Attack Defence liquid concentrate, particularly for scale and mealybugs, the active pesticide is thiamethoxam (bright orange bottle, UK garden centres) I ve used it on the cymbidiums a couple of times since as it also mentions thrips and others on the label and I think I may have a few of them at times, and maybe the others include red spider.. the plants have suffered no ill effects from this either.

I don t see too many red spiders these days, but I cant say which or what might have helped the most (not very scientific, sorry)

Date: Sun, 11 Dec 2011 17:05

Hi Everyone, Having enjoyed seeing so many of your charming little treasures through the list, I thought I would send in a real monster for contrast standard Cymbidium Angelica , a cross made by McBeans over 50 years ago, according to Wildcat it contains 22% Grandiflorum in its parentage, hence the size of the blooms.

This year it put up 3 spikes, and I was looking forward to an impressive display, however, not to be, the buds on the two smaller spikes all turned yellow and aborted, I think it was affected by the mini heatwave we had in late October, it was in the greenhouse by then and I think it got a bit too warm, so just like any cymbidium can given too much warmth at a critical bud development stage off they all fell....luckily I have the largest spike to enjoy.
Perhaps not the prettiest plant ever, but up there with the largest size blooms in my collection.

Incidentally, these two photos were taken on different days, that s why they look rather different. The one with the ruler showing the size was in the sunshine, the complete stem was today in quite cloudy and dull
conditions, I had wanted to wait to get the full stem when all the flowers were open.

Whatever as they say ... I can only say that some 20 plus years ago I used to grow a lot of pleuros and masd in fact I had a small greenhouse 12 x 10 I think, devoted entirely to them ( I sold the lot in order to have a greenhouse to devote to Vandas in 1990 or thereabouts ). When I had the pleuros etc., I was a member of the Alliance, and found several of the members very helpful indeed towards a fellow member.

I can entirely understand the viewpoint you take if they are not helpful and friendly you don t want to join , but there are a lot of folk out there present company excepted of course who are always willing to take and never to give , and they can be a pain in the neck .

Just a few thoughts.

It is a magnificent flower, and I don t doubt that had you succeeded in keeping all of the buds it would be a magnificent sight.

But it was the general tendency to breed bigger and yet bigger flowers ( and plants as well) which killed off cymbidiums as the amateur orchid growers plant of choice.
When I went to my first orchid show in 1961, there were classes for 1 cymbidium, 3 cymbidiums. 6 cymbidiums,. and also for cymbidium seedlings flowering for the first time ; they were that popular ; One end of a large hall ( the great hall at Aston University in Birmingham) was entirely filled with a great bank of McBeans cymbidiums which they brought in two large vans...
Nowadays it is possible to go to a Spring Show and look in vain for cymbidiums at all or is that perhaps a slight exaggeration ? You certainly won t see many of the old standard varieties.
Ever smaller greenhouses, and ever more growers using window sills only is part of the story too.

Nowadays I have only one greenhouse, albeit a big one ; and only one growing temperature. But what I miss most from the collection of greenhouses I had when I lived at Minchinhampton is the 12 x 10 devoted solely to cyms. And I envy you !

As I may have said before, much of my interest and most of my new acquisitions for some time now have been in tribe Vandaea , sub-tribe aeridiniae especially – which are what I personally call vandaceous orchids.
If you think that Angraecums and Aerangis are vandaceous, then it is necessary to include everything in tribe Vandaea – all three sub-tribes – and good authorities have thought so in the past ; I use the term in a narrower meaning. Will be interested to know what others think about this question ?

Acampe papillosa – a beautiful flower you will agree ; tiny flowers, only 5mm across. The plant a mere 5 inches high. But three spikes and maybe 50 flowers when its done. I can’t claim to be the great cultivator here – this is a plant I bought on a certain auction site a couple of weeks ago, for 99p plus postage !

Rhynchorides Thai Noi . This is a hybrid between Rhynchstylis coelestis and Aerides houlletianum. Curiously the plant and flowers are of much smaller stature than either – both parents would typically have a leaf span of at least a foot to be flowering size, the leaves here are a mere 4 inches long. First flowering from a seedling.

Hi all,

There is something that I have been wondering about for nearly forty years or so, and it is to do with the fact that some of us have never been able to grow certain orchids.

I have related it to my native New Forest in the south west corner of Hampshire in England.

The soil is known as acidic, and it has much heathland where heather and such plants grow. The New Forest is surrounded by CHALK where of course its plants do not grow.

One Genus of our wild orchids, namely Platanthera has two species, one of them grows in chalky soil, and the other grows in the New Forest acid soil.

Now I am no scientist or biologist and I read about photosynthesis etc. etc.

My question is this. Do any of you think that there is a relating fact as to why some of us have never been successful in trying to grow a certain epiphytic orchid because it has something to do with WHERE it grows in relation to the surrounding soils.

I rest my case.

Cheers, Rodge.

To those not used to chemical mumbo jumbo a sticker such as fairy liquid will actually stick the chemical to the leaf surface and when the scale decides to venture out they will meet the active chemical on the leaf sorface .
Ps A sticker will hold the chemical in situ wheras if you spray a chemical with no sticker it will evaporate and be of no use when the bug decides to explore its surrounding

Roger,

Just making sure I understand the question... If it is an epyphitic orchid, the surrounding soil would not be a factor, so I am assuming you mean the growing medium, right?

I have sometimes considered if the type of bark used would actually make a difference to the orchid growing on it, as not all barks will have the same chemical make up or pH as such. However, as the only type of bark I have come accross tends to be fir bark, I have not been able to experiment on my ideas.

Hello everyone

When I have seen epiphytes in the wild I have been too busy exclaiming over them, photographing them and trying to keep up with the rest of the group to take proper and considered scientific notice of the trees they were growing on. However, I do remember a very interesting lecture at a Congress once (at Leeds uni?) about preferred orientation. We were told that some orchids are extremely picky about their whereabouts and will only grow on the sunny side at noon, ie. south facing, or the damp and therefore mossy side (north), or the underneath of the branch, or the top, or whatever. So perhaps elusive success requires even more research into the minutiae of habitat including, no doubt, the pH of the bark.

Brian, Nice to see your cattleya pictures, I particularly like the red one. I believe at one time you had the catts in the same greenhouse as some of your cymbidiums, is this so ? and if it is how are you managing the different temperature requirements ?
I agree about using what you are calling a sticker when spraying any bug killer, I ve also heard it referred to as a spreader . I always add something, used to use a drop of washing up liquid, now gone all up-market and have a bottle of Growth Technology Wetting Agent. Whichever I use it certainly helps the spray to adhere to the underside of the cymbidium leaves, that s where it needs to be to do any good against the red spiders. I soon know if I ve forgotten to add it to the mixture as everything just runs straight off the foliage and ends up on the greenhouse floor.

Richard, Your comment about the Listerine is interesting, I have heard of an insecticide spray (not available in the UK) called Envirospray, which I believe is based on all natural products such as tea tree and extracts from other plants supposed to have antiseptic / anti viral properties, when it has been used everything has a very clean smell around it. Maybe some of our Australian members have used it and can comment. The person who told me about it said he knew it worked wonders against red spider, but he wasn t convinced it killed them, just that they didn t seem to like it and went elsewhere. Maybe its the same sort of thing with the Listerine, maybe red spiders just don't like the antiseptic properties of the products..
I need to make up 6 ltrs of spray to do my greenhouse full of cymbidiums, so I don t think I ll be using it.

Tricia, Over the years I have had various sprayers, and there have been many
replacements and upgrades, sometimes due to failures sometimes just the need
for a larger/better sprayer. The one I am using now I have had for about 3
years, its a Watchman 6, (6ltr). I got it from Simply Control, I see they
still list it on their website, price just under £50. I've been very
pleased with it so far, very robust construction, manual pump-up with a
pressure gauge integral in the handle, I can only pump it up to about half
way on the dial, but even so it maintains a good spray for a decent length
of time, I probably only need to pump it up about 4 or 5 times to do all the
greenhouse. Also its got a good strong spray lance, starting at 60cm with an
integral extension that pulls out another 50cm, so you can have a reach of
110cm (4ft ish) plus your arms length, so its easy to do the plants up on
the shelves and in the most difficult corners. It comes with a selection of
nozzles. If I had to find one thing to criticize it would be that the
plastic is such a robust thickness, and being dark orange in colour, it can
be difficult to see the water level inside it when preparing a mix, I
usually end up trying to get it into a shaft of sunlight to see where the
level is, but don't be put off by that, perhaps it will be easier to see
when I get my new specs !!
Other than the Watchman 6 label, the only other thing that might help if you
want to search for a better price than above is the word Kwazar impressed
into the plastic.

The technical word for what is needed is surfactant ; Commonly called wetting agent . This reduces surface tension so that the individual drops spread out to ensure complete coverage of the sprayed surface.

Fairy Liquid is generally considered to be a bad idea. 'Kind to your hands” in the old TV jingle means that it has glycerine added. Glycerine clogs up the stomata ( turns into a solid sort of gum as the water dries ) and prevents the plant breathing. Can be a most effective way of stopping growth !

If you want to add a surfactant, and I agree that it is a first class idea – and thanks for reminding me, I had quite forgotten ! – then do buy a proper one.

I once did a botanical holiday in Corfu in the early Summer, and of course the Mediterranean orchids featured strongly.
I recall being taken to one area of light open woodland/scrub, where we found 28 different species.
The interesting thing perhaps relevant to this thread is that there were two soil types mixed up in this area , due to some remote geological history I suppose, and wandering along you would find areas with certain plants but no orchids, and then some yards further on, different plants and the orchids would be there.
I remember that one of the soils was called testarossa . probably they were of different pH and humus content and EC and everything else. The orchids all liked the one kind but not the other.
Of course you can do the same in certain places in the Alps I remember finding the two different species of rhodedendron on one trip ; one grows on alkaline soil and the other on acidic , and never the twain do meet.

But I really can t see how this can translate into the greenhouse. The ones that can t be grown are simply being given the wrong compost/water/feed surely ? The fact that the greenhouse may be on a chalk substrata can t make any difference unless you are drawing water from it, or growing in it ?

Back in the days before pocket EC/pH meters , when we all knew nothing at all about water, it is true that everyone knew that you can t grow orchids in say Evesham, but you can in say Stratford on Avon , and no-one had the faintest idea why . But by the time I lived in those places, word was beginning to spread, and after doing very well in Stratford I moved the 10 or so miles towards Evesham and start killing orchids, but a water analysis soon put me right ( Evesham water is full of Nitrates from the stuff the farmers pour on their cabbages, day and night...) and I started to learn about Reverse Osmosis.

Hello Sheila,
Yes all my cattleyas,miltonias, phallys,vandas and paphs are ib the same greenhouse as the cymbidiums.The temperature is roughly 54F but the phallys are under lights for 12 hrs a day which increases the temp by about 5F and at night they are under warming cables.The flourescent lights are brilliant because they give off a dry warmth which helps in creating a dry atmosphere so precious at this time of year.The bigger catt are above the flourescent lights which give the pots a warmth at the base of the pot.I will take some photos of this greenhouse so people can see where the plants are in situ.Of the 80catts,20 paphs,10 vanda and12 milltonias only a couple of catt would seem to apprecate a higher temperature. I have also suffered with my cymbid in the warm weather with 2 plant dropping half their buds. Your acetamiprid insecticide is the retail version of Gazelle which we spoke about some time ago.I have some Ray Biltons plants flowering for the first time this year so I live in the hope that I mighr have something special.Everything I grow as you know is in Rockwool and all are looking very well and my milts are now in the same medium for 2years plus. Hope to see you at the Wessex meeting in Jan.Brian
