What's all this 'bout Vista then?

Here's me stuck in the Ark with XP-SP3 thinking, in my infinite ignorance,
that Microsoft had at last got its act together and then Geoff casually
relates a four-times-a-year reinstallation job of Vista !
Oh for the days of the Apple ][ when we pushed electrons along wires by hand
like beads on an abacus and we actually had a tabulated 'Atlas of ther
Apple][' of all the Hex destinations for the said charges!

Ah! Nostalgia ain't what it used to be.

More seriously though, I believe that Microsoft has another, even better OS
on its way. Will I live long enough I ask myself!

Mornin' Geoff,

And it looks like another wet one!

I saw your E-mail and the answers.......The list of traders should be on the BOC website but it appears to be running a little behind!

Should I say what I think ??? Same old bloody excuses. And as I am sure, we both know, and to that end, many of us know certain 'Officers' of the B.O.C. I nearly always ask myself.....'What's the point'?

And there I will leave the B.O.C. as I just switch off, but before I do, B.O.G.A. and the R.H.S. all seem to tarred with the same brush.

On Saturday my friend and I were looking at the 'Italian's' website to order some orchids. Now that's what I call a Website. Having a trawl through their SHOP is a sheer joy. And then when each plant has cultural notes etc., well that is what I call being 'On the Ball'. And when you read the Italian to English translation, some of the words make you smile because they are so wonderful.

They obviously care about and want customers.....do the B.O.C./B.O.G.A./R.H.S. want the customers.....I think not.

Note: I altered the colour of the words, running a little behind.

Maybe I will remember to let you all know when the orchids from Italy arrive.

I did think about going to Dawlish Warren, and then I saw that it was a 220 mile round trip, cost of petrol alone would be about £35, and then the other extras, entrance fee, maybe parking fee, a nice pub lunch etc. Getting on for £70 for starters, that's before any orchids are purchased.

No, as on Saturday I put in the order to Italy. No car, no expenses, excellent plants, just wait for the Parcel Post.

Rocky, maybe the killjoy, but it sure suits me.

Hello all,

I think it was last year when Roger and Dennis were moaning about rot at new
growths or emerging flowers of Trichopilia tortilis. Well, here is a photo
of my Trichopilia tortilis which was flowering altogether with 13 flowers at
the same time a few weeks ago. To say it with Roger's words − I was highly
chuffed. Although I grow it in pure hydroculture and the water level stands
just 3 or 4 cm below the surface of the potting medium I've got no rotting
problem at all.
At the moment Clowesia russelliana is in flower. I bought it in late 2005
mislabelled as Catasetum scurra but this is an invalid name and synonym to
Clowesia warczewiczii. But this plant isn't definitely Cl. warczewiczii. I'm
convinced it's Clowesia russelliana by comparing pictures from the internet
but any other information is welcome.
Last but not least there are two update photos of Paphs from my collection -
Paph. hermannii and Paph. liemianum.
Paph. hermannii is regarded by some taxonomists to be a natural hybrid but
I'm not convinced by this statement and therefore I keep on using its
species name.

Best regards from Germany, rudolf

Jim − I wish you good luck with your Cymbidium seedlings, but can offer no answer to your query regarding when they may put up their first spikes − I think it will all depend on you and your culture.
I have one 'seedling' which I have been growing for 5 years now, and still no sign that it is going to flower, on the other hand I have flowered plants grown from bare back bulbs in 3 years.
I much prefer to leave the seedling care to the 'experts' and to buy plants I like when I see them in flower.

Ah yes, but a nice pub lunch ? That's always worth going out for...

But you'll have to wait for your plants from Italy , believe me ( I
ordered several weeks ago, and what they said , freely translated is
, the sun shines, the pasta is ready , the cork is pulled from the
wine − orchids ? manana ! or is manana Spain ? ) and I do agree
with all that; I can wait a few weeks, if needs be. Maybe one year
I'll go and fetch them ( the orchids) and try out the pasta and wine
whilst I'm doing it.

But I have thought , and at present plan , to go to Dresden next year
for the European Orchid Congress . According to Michelin it is 700+
miles , but an interesting journey ( I plan to take three weeks there
and back going via some wine routes too , and hope to bring my car
back well laden. I shall see how DOG are at organising things .

One of the Dutch plant factories told me that they get plants ready to sell
on first flowering − one tiny bulb and one big bulb, with 3 or 4 spikes, in
15 months from planting a plug with a single growth seedling about the size
of a pencil. They told me how too, but I won't bore you with this tale here.
But that is culture which few of us could ever hope to emulate.

McBeans in their heyday, with Ray Bilton in control ( collecting gold medals
for his displays at Chelsea Flower Show, year after year, and endless AMs,
FCCs etc,) thought that anything less than 5 years to first flowering was
pretty good. But that was old fashioned culture by the Dutch standards.

Good morning to you all,

I have what I call an 'Insect Question'.

Let me explain. My aluminium benching has capillary matting over it, and the orchids sit not directly upon it, but on upturned plastic pot saucers.

This morning I noticed some very tiny critters crawling on the matting. They are transparent, and they crawl quite fast for their size. The size being.....about 5 millimetres long by 1 millimetre wide. At the front end I can make out two 'pinchers', which I guess may be used to trap something or other.

Any ideas as to what they may be please.

I will try to get a photo posted later.

Cheers Rocky.

Shelia,

I much perfer to buy the flowers grown and in bloom as well, but $25+ for a cymbidium here and just out of flask $0.40. yes 40 cents! doesn't make sense but I figured what the hell and bought 100!

I am really looking for some kind of answer of what other people have done, is it a muture bulb or lots of shoots that lead to flowers... some kind of insight no matter how good.

That is what I suspected, I would love to here more, bore me, please bore me. I would love to here how they do it. sometimes it is difficult to emulate here, I am still working on getting amonia..... I just finished another (roofed) expansion of my greenhouse. It is now the REAL raniey season here untill Nov-Dec, when the dry season "verano" as the Tcos say. May to sept is really just the warm up rainey season, lots of sun and not always rain every day the showers are ususall only an hour or so. So I am passing many many plants from under the shade cloth to below my roofed area. That is why the cymbidium questions I am moving and repotting lots of them. My collection has grown a lot this year, there are lots of Ticos that get tired of orchids or can not flower cymbidiums so I offer them a buck or 2 and next thing you know you have several hunderd or who knows maybe a thousand I am still counting.....

As always thanks a million for you wise wise input.

Paul, Roger et al,
Thanks for the timely reminder of the extent to which nature will go to in order to maintain life (or cause malaise!).
Last year I experienced the interesting phenomenon of a shin bruise infected with a bacterium called Pseudomonas aeruginosa. Nothing special you might think − except that it transpires that the said bacterium also grows in kerosene fuel tanks where it eats rubber seals (747s don't like it!), blocks the pores in oil reservoir rocks deep underground and was of some assistance in breaking up the Exxon Valdiz oil spill. I just thank my lucky stars I'm not (yet!) dependent on synthetic heart valves or other plastic body bits.

However, my point really is that if life can exist in a kerosene fuel tank, there must be quite an ecosystem in Roger's matting.

I sometimes wonder why we don't deliberately grow these bugs to show standards. Then we'd we'd quietly tolerate any infestations of orchids! Now there's a thought.

Cheers
John

Roger,

Oh, those little darlings are sooooo cute!! : )

Hah! Now, you have provided good evidence of overwatering,
decomposing pot media, maybe too much nitrogen, and definitely not
allowing the plants to dry between waterings.

You are quite correct, they are larvae, and not of molluscs. These
are the larvae of, not a moth, nor a butterfly, but rather Gnatus
fungophagus. Okay, so that is not a legitimate scientific name. : )
But, they are fungus gnats!

If they are a bother, there are several things that can be done.
Drenching pots and spraying down benches with diluted alcohol,
ammonia, or bleach will work just fine. There are a variety of
pesticides, and a bacterium, sold as BT, for biocontrol. There are
also a variety of small mites, nematodes, ground beetles, and other
critters that will happily chew upon the larvae. Yellow sticky cards
hanging or posted in the greenhouse are good for capturing the
adults. For me, the easiest thing is to keep up on the repotting, do
not let any media stay too wet for too long, allow some drying between
waterings, keep fertilizing to a minimum, and keep a good breeze going
in the greenhouse. Usually, if you are doing a periodic insecticide
spray for other things, that will keep the fungus gnats to tolerance
levels. So, I would bet that somewhere you have a plant or two in
desperate need of repotting out of old organic media.

One other thing. . ., quite frankly, unless you have a lot of
seedlings, fungus gnats are usually more of a nuisance than a plant
problem.

cheers,

Paul

For some reason, I went back later and reread your message, and noted
your remark about the aluminum bench with capillary mat. I should
point out then that in addition to fungi working on decaying organic
matter, that fungus gnats will also feed on that nice, juicy, and
highly nutritious mixture of algae and fungus (i.e., slime) that
develops on bench surfaces. I would not be surprised if the larvae
are working through the capillary mat. My wife uses capillary mat for
her African violets and fungus gnats will get into that if she does
not change and clean them every few months. This reminds me that some
years ago a friend brought to my attention a massive infestation of
fungus gnats and earthworms that occupied the artificial turf mat that
she was using on the floor of her greenhouse. A wonderful steward's

But here goes.

First, they have to actually grow every minute of every day ( 14-15 hours).

that ) but very clean glass too ! I was there in late May, northern
hemisphere , long daylight hours, but a cloud came over the sun, maybe it
was going to be a rain shower ; the lights came on over the benches ! I
asked, and was told − if they stop growing for the half hour that the shower
lasts, it takes them 5 or 6 hours before they start growing again, and we
can't afford for them to stop for half an hour, never mind half a day...

They are never re-potted − that too slows them down and you would lose
months not hours ; plugs the size of a pencil are put into 15cm pots in a
free draining compost, and grown on until they fill that pot with roots -
and there isn't even room for much compost by that stage, most has been
washed out.

I don't know/remember the watering frequency, and of course have no idea
what they fed them with. They watered by overhead sprays − I asked about
crown rot, and they said no chance, as long as the feed spray was replaced
with a pure water spray for the last 30 seconds to wash fertiliser out of
the crown − but not out of the plant. They said − pure water − no bacterial
growth. Fertiliser- encourages bacteria.

Naturally temperature was controlled day and night to keep the plant within
the optimum zones. You can find those temperature/growth rate curves for
many plants − all green plants are more or less the same, although adapted
to different temperature conditions, but generally speaking growth
accelerates in proportion to temperature up to the optimum and then falls
again past that point.

My guess − not what I was told − is that Cyms would not grow at all at say
10 deg C.or below , maybe even 12 or 15 or below. Would grow faster and
faster up to a figure somewhere about 25 C, then slower and slower and not
grow at all above say 30 − but these are guesswork based on impressions and
reading and experience of my own plants but without having made any
measurements. Certainly they will stop completely at and above some high
temperature.

And remember that growth depends on the Krebs cycle or the other
photo-synthesis one ( can't remember its name) and needs a lower temperature
time for part of each cycle, or again, growth is limited or stops.

I know that some people in the States , when that was a great orchid
production place, experimented successfully with using two growing and two
resting/conversion cycles per 24 hour day − like 7 hours light and heat and
then 5 hours cool and dark ,claiming that a 14 hour continuous warm and
light spell was too long and wasteful, but that kind of stuff is
economically feasible if the whole thing is done in a factory not using
daylight at all and impossible in your conditions or in a greenhouse.It was
not done in the place I am talking about.

Obviously best growth all positive conditions ( heat/light/humidity/air
movement/water/feed/pH control − all under control and kept to the optimum,
but also means negative conditions under control too − absence of pathogens
etc. In fact in the greenhouse I am discussing − which by the way extends as
a single greenhouse to some 6 hectares ( 15 acres ? ) you could eat your
food off the floor which was covered with clean white plastic, regularly
flushed with disinfectant, and never walked on !

The idea of even a spider in that place was laughable. No ventilators − a
very large space − quite high for a greenhouse by domestic standards, has
such a large buffer volume of air that vents are only a nuisance and a
source of ingress of potential pests − mind you, in the Westland part of The
Netherlands, intensive horticulture has been going on everywhere for so long
I doubt if any pests actually survive anywhere in the country.

The plants were on trays mounted on pallets which were moved around roller
conveyor tracks by an automated computer controlled system, and an operative
sat in one place ( near the door) clicked with his mouse, and presently the
next tray would move in front of him for inspection − he got to see all the
plants , usually once each three months − I think there were 2 or 3 million
plants in that greenhouse...They told me the investment was 15million
Euro... a bit more than I want to spend on my hobby , and what would I do
with a few thousand flowering plants rolling off the production line every
few days ?

By the way − the whole place was run by a staff of 17 , including the boss
who took me round.

As a comparison , the first professional nursery I visited in England, about
1962 , used 6o feet long greenhouses, 10 feet wide, each manned by one man
and a boy − of course they had to stoke the boiler, empty the ashes, spray
the plants with a brass hand pump syringe for humidity , roll wooden blinds
over the glass to provide shade, etc etc...quite aprt from watering and
picking the slugs off the plants etc .but this explains why in 1962 a nice
cymbidium with 4 spikes would cost far more than I could possibly afford (
40 pound sterling ? At a time when I earned 20 pounds a week ? ) and now
those plants t coming out of the Dutch factory are sold at auction for maybe
ten pounds... some things do get better in this world !

Well, you did ask...

Hi Paul and Andy,

You have hit it right on the nail..........'Bingo', that's it for sure, thanks very much for your input.

Paul, I thought you knew me better, especially how I grow my plants. And when you said: Hah! Now, you have provided good evidence of overwatering, decomposing pot media, maybe too much nitrogen, and definitely not allowing the plants to dry between waterings.

Overwatering.....no.
Decomposing media.....no, it can't happen, unless we wait for a few thousand years for my stone chippings to decompose, ha, ha.
Too much nitrogen.....no.
Plants not drying out between waterings.....no. Mine are more or less dry in an hour or so.

Andy, thanks for the website, excellent, but as for Kate Moss..........I'd sooner listen to 'Leadbelly'.

Back to Paul. My capillary matting is changed maybe every two to three years, and at the moment it is just nice and damp, and it is growing a very nice moss.

I will no doubt do as you have informed about the mixture to get rid of the critters, and I was thinking along the same lines of mixing up a bowl of water with detergent or liquid soap and bleach, then just pour it over the capillary matting. Maybe this afternoon.

Again, thanks for the information.....is not this what the 'Club' is all about.

Cheers Rocky.

wow, I have heard people talking about putting lights in greenhouses here. we have 12-13 hours of light at 10 deg lat. in the dry season lots more sun and strong sun, but sept oct here is 12-1 hurs of rain/clouds. The cymbs below the plastic have 1200-1600 footcandles when in the clouds. never would have thought that would shut them down, I always assumed temp and light worked together.

Washing the fert. off (30 sec of pure water) interesting.

never repotted? I always thought that putting a small plant in a big pot was not a good Idea as the plant will spend a lot of time growing roots and not leaves? Repotting the cymbs I have I try to take the whole plant root ball out and stick some media in a pot and put a little around the root ball and done. as apposed to dividing a plant that includes cutting and chopping and cleaning and ... and more molesting. intersting.

I am glad I do not have to sit and inspect 3 million plants! I'd be looking for a distraction after the 1st pallet!

I also have an original "The Orchid Growers Manual" by Samuel Williams, 7th edition. It cost me £35 to have it rebound, and am asking £75 +P&P for it. Very reasonable I think because it is in excellent condition.

Hi Nat,

I don't know if this can be of any help, but in an attempt to free some space in my living room, I have bought myself a shelf unit from IKEA, which has been fitted with 4 fluorescent tubes of 18w per shelf. Two warm white and two cool white tubes, as they are supposed to emit light on the red and blue spectrum (useful for plant photosynthesis). I have moved as many of my phalaenopsis and seedlings as I could fit in there.

It might just be wishful thinking on my part, but I think in the past month I have seen an improvement on my seedlings, and also on the growing tips on roots of my phalaenopsis placed there.

Only time will tell if I am right.

Hi Geoff, in a recent article you mentioned how you had switched to maxicrop fertiliser and calcium nitrate to improve your paph's quality of growth.Like you i am a keen paph grower, i grow them all under growlights, as you may remember from a previous article 'how i grow my orchids'.I used orchid focus as my main food, but i found the plants didn't seem perky or healthy looking aand seemed to loose more bottom leaves than they should;after a long thinking period, more observation, i realised i was following the feeding instructions on the orchid focus and was only getting around 60ppm, so i surmised that part; if not most of the problem was under nourishment. So i have swithched to maxicrop orchid feed recently just so i know the plants are getting the best ppm of nutrition and because you seem to have good results from your own plants. The problem im having is finding large enough bottles of maxicrop orchid feed.Ive tried all my local garden nurseries and orchid growers with no success,i got some from ebay but only 250ml,ive emailed maxicrop with no reply;can you please tell me who i can get some larger bottles from on the net or otherwise as i have around 600 plants and 250ml is going to last long.many thanks!happy growing!

As to lights, I recall using cool white tubes − but they have to be real
close to the leaves − 6 inches above as I recall it. Gro-Lux are generally
not considered to be worth the very considerable extra expense.

I recall that 74 was the pattern for the best choice ( try asking for that
at an elec wholesaler. − no more expensive than any other )

Of course fluorescents don't give the right spectrum for ideal flowering,
although good for growth. You need some of the big Philips sun-gro or
something like that − expensive , heat generating, large...

Hello Jim,

Sorry for the delay but I was busy with some other things.
My Trichopilia was flowering from mid to late July 2008. I took the photo on
July 28th. After I had a look at my 2007 photos of this plant I found out
the curious fact that I took the photos at the same date , July 28th. But I
saw other Trichopila photos in the net about 4 weeks earlier this year.
Regarding hydroculture I wrote about that issue several times here e.g. on
Dec. 18.2006 and I don't want to bore the other subscribers.
Here's just thus much in a brief version.
- You need an inert potting medium (no decaying or decomposing and therefore
no releasing of other nutrients)
- The EC of the nutrient solution should suit to the species (between 400
and 600 micro S, Catasetums even more, Paphs much less)
- I shorten roots when I change to hydroculture. Roots must grow by
themselves into the water/solution (aerial grown roots will definitely
die/rot when you put them into the water/solution)
It works fine in mine conditions and saves me often watering the plants. I
only water (fill up solution) every 3 or 4 weeks (depends on the weather).
But I'm an indoor grower and not to compare with your huge amount of
different plants.

Best regards from Germany, rudolf

Gavin − I have about 350-400 paphs and I am now watering them − and
everything else − by individual handling of the plants ( quick inspection
etc whilst I do that) then dunk in a bucket, drain, and then back on the
bench. 25 gallon of mixture did all the plants in my house − maybe 2000 ,
i.e. the cattleyas, vandas, etc etc as well as the paphs.

Now I buy Maxicrop in 1 litre bottles, and it takes a couple of capfuls in a
3-ish gallon bucket of rainwater to raise the EC from 30 to 300 ( approx). I
then do the same to make a bucket of Calcium Nitrate, and then again to make
a bucket of a general purpose fertiliser like Focus . I mix all three
buckets into one dustbin, stir, correct the pH , and add disinfectant
(Physan). Then I read the EC of the mixture. I add more rain water to bring
it back to EC 300, Takes half an hour or so fiddling about with pH and EC,
and diluting again and repeating until I am satisfied that I am in range -
narrow range for EC ( 290-310) and same for pH (5.8-6.2) At the end of the
process I have this dustbin full of mixture which waters everything and
lasts me until the next time. Every 2-3 weeks now until next summer...

But I expect my bottle of Maxicrop will still be lasting until then.

I don't know where to buy it in large quantities, and I fear for your
collection if you pile it on that heavy !

BTW as you may know, I don't use and don't like PPM − it is not scientific.
What ppm meters actually do is read EC, and then "assume" that ALL the ionic
material is just one salt ( I think it's potassium nitrate, but it does tell
you somewhere on the Hanna site ) and then it multiplies the read EC by the
constant appropriate for that particular salt , i.e. 1.6 ( again , from
memory).

Now all the dissolved material is not Pot. nitrate. And all the dissolved
ionic material does not have a constant of 1.6. Indeed 1.6 is deliberately
chosen as being in the middle of the range of likely possibilities. All
this seems to mean that your ppm meter does a few more guesses than I would
like.

In addition , I have a theory − unproven,( I wouldn't know where to start
anyway) that the significance of fertiliser level is based on the
electrochemical series. That what happens in a moist or wet substrate is
that ions move towards the anode of the electrochemical circuit ,( the
roots) and if I am explaining myself badly its because I see it a little
vaguely and I have never had the opportunity of talking this through with
someone who knows about electrochemistry ( I used to do Patent work in that
field for a Prof. and his team at one of the Universities, who were clients
of mine − many years ago − I have been retired from full time practice for
more than 14 years now .

However, what this means is that the heavy metals − such as any copper
present − will move preferentially to the roots, in a higher EC mix − the
voltage will be higher .This I think is "why" high EC concentrations are
poisonous. So even though your fertiliser contains only traces of many
elements, high ECs increase the risk of plant poisoning ( leaf tip burn etc
) occurring.

Now I get to the crux of the argument. It is higher EC which is important -
the E does stand for electric !

So I don't want to bother with ppm − go straight for the measurement which
matters.

I can't comment on your ppm values, since I don't use them.

Hope this helps.

It does not seem to be very critical what dilution you use . I have done 1:4
, and 1:10, fro what came in the bottles labelled "cloudy ammonia". I also
find that when I have made up a bucketful , and keep it in a bucket with a
reasonably close fitting lid ( an ex- fertiliser bucket) it seems to keep
quite well − at least it still smells just as strong every time I take the
lid off − so I keep it , and when I find a plant with slug damage, I dunk
the whole plant.

Geoff, I believe the typical household ammonia products are about 5% ammonium hydroxide. And if memory serves me well once again, the only difference between clear and cloudy household ammonia is the addition of detergent which gives it the cloudy appearance.

Hi all,

I saw these two Phalaenopsis in a large store. The photos were taken through the wrapper.

I must say that I do like the nice patterning and outer different shade, and this just goes to show that the people who hybridise Phalaenopsis will no doubt one day come up with some very stunning patterns and shading.

But, when you look at the photo of that monstrosity that they try to get the unknowing public to buy..........well, I think that is disgusting.

A Phalaenopsis which was made by 'Mother Nature' has a nice flat flower with the lip standing out at right angles, not like those ugly things.

Regards, Rocky.

Thanks for your gorgeous pics of Cirrhopetallum vaginatum and Eria acerba,
what is the whitish topping that you have on your compost, it looks really
neat?
I have had two lots of flowers on the Dendrobium dawn marie that you
recommended.Can't send any pics yet,I got it from Wubben last year. Much to
my surprise it's done all that with the roots completely rotten in the semi
hydro so it's now in "spag and bag"
I just purchased a Dendrobium xanthophlebium on E Bay any of you know
anything about it (culture ect" as it is quite new to me? Thanks all of you
for all that I have learned on this forum.
Regards
Cyrus
