Mornin' Sue,

Just in case I got my wires crossed..........we have got clay pots over here, most of them now come from Italy and other places.

What we do not have is the clay pots with either holes already in them, or the type with slots in their sides.

What type of pots do I use for my Phalaenopsis, you ask. Answer is, clay pots with holes in their sides which I drill myself.

So that's where Wisconsin is, western side of Lake Michigan. Must get cold there in winter.

Kind regards, Rocky.

Mornin' RonBow, and also a very good morning to RonNew,

RonBow, you asked me about the gravel and Perlite mix. Yes, no problems there.

You and others may be interested to here what Wally Thomas of Vancouver has to say about Perlite.

I contacted Wally many years go and was delighted to see what he had written.

Just punch/key in: Wally and Barb Thomas Vancouver and have a good read. It will also tell you to 'Click here' to see Wally's article.

Off in the garden now.....much to do!!!!!

Hi Alex,

I also tried Neem Oil, and like you, I did not rate it that much. Also the mixing and storing was not as easy as the ready made items.

Have you tried 'Provado' against the Red Spider mite, as I have found that it works if given repeat sprays every now and again.

I still think that PROVADO is just about the best and most handy item that we can have to combat pests.

Regards, Rocky.

I have now got back home after a hectic month of visits to half a dozen
different places, staying anything between a few hours and almost a week ,
visiting old friends, relations, and Hotels to viisit old haunts or new ones
- including the Paph Soc. Meeting, and latterly a visit to the new
Festival Hall and to Greenwich ( which I have been wanting to visit for
ever.) − the orchids having been hastily watered when at home between
visits.

Tonight I was able to look at the plants for the first time for a bit , and
took a few snaps which I'll share with you in a couple of e-mails.

In this one we have two Bulbophyllums.

1 is B.echinolabium. A seedling flowering for the first time for me. It's
made a bulb almost the same size as the last one in the traders nursery ( it
is seed-raised from Stock in Germany , I think. )

The flower measures 25cm − 9 and a half inches natural spread − as seen -
or more than 27cm if I hold the top petal up straight. The column is quite
amazing − worth closer study − hence the second picture.

Only one flower − not surprising on a plant like this − the leaves are less
than 10cm long 4 inches long − and the best bulb the size of a smallish
damson ( Hope this means something to those not in UK − I'd better add less
than 2cm ). But hre is another bud − maybe it will be sequential flowering.

2 is B.saltatorium. Same source, here grown in a 15 cm long mini seed tray -
with 4 spikes . The flowers are rather less than 1cm across − apart from
that amazing lip.

Enjoy.

More pics as promised.

The "oncidium" is wrongly labelled on the file − a slip of the
tongue/mind/fingers . It is of course an Encyclia − one of the "cockle-shell
orchids" . The nicest one in my opinion , and I grow several different
species.

Pine River Blue is a vascostylis − multigeneric hybrid of Rhyncostylis and
Vanda (?) − maybe I have shown this before ? If so forgive me. This is very
similar to V.Thai Sky , but maybe a better colour than any of my several
Thai Sky plants, and certainly a better shape. And most of my Thai Skys
flower rather later. But always welcome , such a brilliant patch of colour.
Two spikes on my little plant − still only single growth ( but my biggest
Thai Sky with about 8 growths has not flowered for a year..)

Phrag Sorcere's Apprentice − doing very well since potted on. Has four
spikes, the two best are 95cm high − makes quite a majesctic plant. ( I
think it ought to be a fully-ranked sorcerer now, not just an apprentice.-
joke ) I have had this since one of the old Newbury shows , maybe 5 years
now, and it just goes on getting better and better.

Epiphronitis veitchii ; This is supposedly a primary hybrid between a
reed-stem epidendrum ( E.radicans I think) and Sophronitis grandiflora .
Flowers in growths only15-25cm high , and rapidly makes a scrambling mass ,
almost always in flower. It's a plant I have loved for a very long time
since I found one at the old McBeans nursey and begged a few bits − in 1962
I think ! This is not the same plant , however.

I have had a couple of goes at remaking this croissm, with no success , and
once discxussed this with Brian Rittershausen,( of Burnham Nurseries0 and
he told me he had tried lots of times, and never set a pod ; probably the
parents are mis-rported, as often happened − happens , for that matter.

Paph Transvaal − just to remind you that I am paph grower ( although I am in
trouble with NCCPG for dragging my heels about providing the annual plant
list which they demand − I have been shy of this for some years , ever since
a friend with what was then a remarkable collection of phrags was raided,
and the best and most valuable plants stolen − why make life easy for
thieves ? Its all very well folr NCCPG to say they will keep the list
confidential, but its not their plants which go if they slip up ! )

I have several Transvaals including at least one awarded variety, but this
is my best one, even if not seen to its best advantage here. As you see 3
flowers, and two buds to come ( which is quite good for any of this kind of
paph ; and a second spike elsewhere on the plant) The best flower not quite
15cm.

I repotted all my paphs into hydroculture using mostly Hydroleca some months
ago , and I'm just now repotting again to admire the new roots which are
growing , and cut off the old ones which have rotted in the water . I have
no doubt that they are doing better in these conditions than they were
before. Another 12 months of root growth , and the next flowering should
be much better in size and colour too.

Hello Rocky − yes I found neem fiddily. I had to warm it up and put a couple of drops of washing up liquid in it to get a good mix.
I have used Provado but the soil drench − I find it very effective and dunk everything a couple of times a year. Some people dont like it but I think it could be because being systemic it takes a few days to work. Anyway I havent found it so effective against the dread RSM − bifenthrin works at double strenght and some Baby Bio organic stuff works as a contact only. This is labelled 'contains fatty acids' but I have a feeling its just soft soap!
I hope you get this as i have just disabled my listing for a few days hols.

Whaaa, The Blue Vascostylis is an amazing colour.
Is that the real colour or have you been playing around with your RGB/CMYK settings? Only joking.
Everyone should have an Epiphronitis veitchii as it flowers and flowers all the time. A very old Victorian cross.

Speaking of hard water and distilled water...

A fellow grower told me last week that she collects the water that condenses
off her central air conditioning unit and uses that to water her orchids, as
"it is distilled − perhaps higher in copper but the orchids don't seem to
mind that." And she does grow beautiful orchids!!!

Any thoughts about this method? Mine conveniently drains into the utility
tubs in the laundry room. Should I collect and use it? Is it distilled?

Thanks,

Colour is quite a problem − the Bulbo echinolabia has turned much redder
(petals − the column really is a brilliant raspberry jam colour) when I look
at the copy on the incoming mail ( than it was on the copy I sent) and I
noticed that when making the pic to send, and I turned it into a jpeg ( I
shoot in Camera RAW and work in PSD) it changed a bit too ; probably my
fault as I work in Adobe RGB(1998) as my preferred gamut , and I really need
sRGB for the web.

I notice also that these flowers are a different colour on each of my two
monitors − suggesting I need a re-calibration (again).

If I have a spare hour or so I'll have a play at the blue Vasco − but yes it
really is a dark solid purple , on the blue-ish side − much better than
(almost) any large Vanda I have ever seen.

Subject: Re: [OrchidTalk] Sue's orchids..hard water...how to grow amazing phalaenopsis...
Date: Thu, 02 Aug 2007

Barbara, it is true that water from any condenser system − your washing
machine dryer, tumble dryer, de-humidifier, air-con etc, is the equivalent
of distilled − except perhaps in bacterial terms.

But don't be afraid of hard water !. Our plants really need all the calcium
and magnesium they can get , since they don't have roots in earth- which
almost always has enough.

Water − all round the world and from whatever source − always seems to
contain Calcium in about four times the quantity of the Magnesium − which (
surprise, surprise ? ) happens to be exactly what green plants need.

The ONLY disadvantage with hard water may be ( depending on the kind of
hardness) unsightly marks on the leaves. Keep it off the leaves and onto the
roots, and no problem.

When I buy phalaenopsis from the supermarket or garden centre − we usually
have a basket of half a dozen in the hall , with some ferns, begonias etc -
I keep them in the house for a few months on the original flower stems , and
NEVER feed. I hold them under the cold water tap in the kitchen − we have
hard water from the limestone , chalk and flint sub-soil of Salisbury Plain
-. I do this once a week without worrying about looking at the roots or
letting them dry out − then drain and return to the hall.

Remember, these are not orchids, they are phallys ( joke) − the point is
that they are really cast iron − they have to be to stand being "grown" by
the ordinary man/woman in Walmart/Tesco, whatever.,

When they have finished flowering on the main stem, I cut that to the base
and take to the greenhouse, where I try to grow the plant into a specimen (
with not enough success to actually boast about, but enough to make me keep
trying). On occasions I rub out flower spikes, to try and grow bigger
plants.

However I have very recently learnt how the Taiwanese grow those amazing
plants with half a dozen spikes and hundreds of flowers which you see in
pictures of their ( and the Japanese) flower shows; I'll share it with you.
They grow on until they have 8 or even ten large leaves without letting them
flower; they never let the temperature drop below 25 degrees C , night or
day − then they don't even try to flower. When they have got those plants,
they return them to more normal conditions − flowering is induced by
temperature drop.

I'm still thinking about how I can get that 25 degree minimum without a
second mortgage..

All the bulbo's are in Perlite, hanging up in my greenhouse ; minimum day
temp 22 deg, min night 19 deg ( Celsius). One layer of double bubble plastic
on the outside of clear glass, one layer of 60% shade cloth on top of that.
Watered mostly − meaning at every watering in the summer − with rain water
with an added ( varying) cocktail of Calcium Nitrate, Hydroponics fertiliser
designed for zero EC water , a dash of Nitrozyme or ( most recently) Humic
acid concentrate , all made up to EC 500 , pH 6.0 ( + or − 3% ) occasionally
sprayed with Magnesium Sulphate ( Epsom Salts) at EC 1000... and if I'm in
a hurry, or short of water, just doused with tap water ( EC 500 , pH 7.5 the
last time I measured) ...
In the winter, which here in paradise is December and January − if I'm at
home, then I often/usually miss out the feed. If I'm away ( we often go
away for several weeks over Christmas − my dearly beloved does like a nice
cruise ) then I have a neighbour who visits the greenhouse and waters
everything far too often with the mains water.....

I have four Cattleya intermedias and four Dendrobium nobiles that I want
to sell. They are all in good health, the Cattleyas are seedlings that I
bought some four years ago from Equatorial Plants, one (which I keep)
has flowered well for two years running and has a lovely scent, the
others haven't yet − they have not been kept in the same conditions, so
haven't grown quite as much.

The Dendrobiums are clones of the one in picture − it seems to be an
extremely vigorous grower and flowers profusely with an intense perfume,
so I expect it's keikis to do the same. This is a plant I bought 6 years
ago at Kew.

I'll part with them for £10 a piece. Please feel welcome to contact me

Geoff,

Mites love humidity, it is free water that mites do not like. High
humidity is essential to happy mites. Free water interferes with
their activities and will drown them. Free water coming in the form
of rain, or hose sprayers, or misters, or other forceful drops or
streams of water are not conducive to mite happiness. The seeming
increase in mite populations under hot and dry conditions provides a
more complicated, multivariate situation. Mites like heat, but like
all other species, only to a point. In general, plant-feeding mite
reproductive cycles decrease in length in relation to increased
temperature, this results in more generations over a shorter period.
In most anthropogenic environments increased heat often has decreased
humidity in the habitat due to the lack of natural feedbacks, and
this rough correlation increases over time. At some point the mites
are increasing in population density at the same time that they are
forced into small habitable areas, e.g.,. the undersides of leaves,
that also have the highest relative humidity within the larger
habitat. In dry conditions the most humid sites on a plant are the
leaves, especially the undersides; note too that hot and dry
conditions stress most plants considerably, thus making them more
susceptible to mites and other beasties. Anyway, the setup provides
for many happy mites. The natural checks on these events are
predators (do not like high heat or dryness, or pesticides) and
weather, both of which normally work reasonably well out of doors in
average conditions, but not always indoors in artificial environments.

One fun little experiment is to find a mite infested plant in dry
conditions. Put a few drops of water where the mites will find them,
and watch the mites quickly aggregate to the water. Small mites
cannot break the surface tension of a drop with their mouthparts, but
bigger mites sometimes can. So, you can torture the mites with
water, watch some desiccate in sheer frustration, and others bloat.

cheers,

Paul

i tried out Schultz Orchid Fertilizer and found that it wasnt very good for
my orchids and it left too much salts in the medium and the nitrogen in it
is locked up as urea, which is not good for orchids and is ment for
terestrial plants as they have bacteria in soil to break urea down into
available nitrogen.
this is just my opinion tho.

I don't know about Schultz − have never seen it in UK − but your opinion
about urea , and needing soil bacteria to make the nitrogen available is in
total agreement with general opinion among orchid growers.

One very popular garden fertiliser in UK is "Miracle Grow" ( it's cheap ) ,
and another is Tomorite ( specially good for tomatoes, they say ) Both are
urea based. Urea is the cheapest form of nitrogen!.

Some UK orchid growers , who are aware how good these products are in the
garden, use them on their orchids, and because they grow and flower say "
there you are then, urea is perfectly OK for orchids" . What we don't know
is how much better they would do with another Nitrogen source !

Additionally , urea is non-ionic and hence does not register on an EC meter
- ( it is the high phosphorus etc which registers) , so it is difficult to
know the strength of the solution. Too much of anything will only lead to
scorched roots and burnt leaf-tips, to say the least.

However, it is very good for the orchid trade ( people using cheap
fertilisers) since down the line, those folk will be in the market for more
orchids. If everyone were like us , never kill a plant , always growing
perfect and ever bigger specimens, which we have to divide up and give bits
away , the orchid trade would have a bad time , and trhere would be nothing
to look at when we went to orchid shows , so what I say is, let them keep on
using the schultz..

Geoff, with due deference to your time in the orchid world Tomorite is used in at least one national collection − Lycaste and Anguloa and with the awards that Dr. Oakley obtains using Tomorite I cannot see your argument. I also believe that the Stanhopaea collection also uses the same fertiliser. Quite possibly Paphs and phrags cannot stand this fertiliser but to generalise and say it is not good for all orchids is a bit sweeping.
I have used it now for the last15yrs and maybe I could do better but to increase the quality by 2% for a triple increase in cost does not seem worth it

Whilst working as a volounteer at the Living Rainforest near Newbury our Amazonica Hybrid Water Lily leaves started going brown and dying. We were then advised that it had been attacked by mites − in the middle of a pond. Notice it was attacked by mites − not red spider mires. I cannot rember the correct figure but 400 comes to mind of the number of mites and each has different likes and dislikes so you can all be right.

Evenin' all,

I have just completed my evening task of watering the tubs, baskets etc.

First for Alex. Yes matey, I always tell people to use Provado as it has served me very well.

Second for Sue. You asked: Does the UK have 4 distinct seasons, or is it more moderate year-round?

Well Sue, it gets milder with every winter. Last winter, and the one before that you could count the frosty mornings on the fingers of one hand. The summers often go on longer and the four seasons have almost turned into two. Just look at this year. An early lovely warm and sunny couple of weeks followed by much cooler weather and then the Monsoon and all the floods. Wettest June and July since records began.

And now on to Coconut husk as a potty medium. Being used by the commercial people for obvious reasons. The price is good, it is light in weight and absorbs water very quickly and stays damp. However, I have just looked at one small pot that I purchased from a garden centre with a Dendrobium growing in it.

Looking at the state of the Coconut husk I will definitely give it the thumbs down.

Tom,

I'm interested in your comments & suggestions re Mapplin 5 disc Fogger. Do you mean the item listed in their catalogue @ £39.99.

Do you have a pond in your Orchid house or do you just immerse the fogger in a tub or bowl of water?
Also how long does the fog last on a bright sunny day?
Seems a good idea, simple, but is it practical I wonder?

Ronbow.

Sue, Hello from a days drive east, and welcome. I am happy to report that
our winters in Pittsburgh are milder than yours, most days. We have also
enjoyed a rather mild summer, all in all. I am guessing you have had a warm
week as my daughter just returned from Grand Haven MI where it was beastly
hot and sunny − perfect for the beach, ideal for them.

The following link to the Robert's Flower Supply site will give you a
regional resource for fertilizer − and other orchid supplies on the rest of
the site.

http://orchidmix.com/cat4.htm

The folks there are members of our local society and are very helpful and
knowledgeable growers themselves. You can call or email with questions and
they are always happy to help. You may even find them at the Chicagoland
event. If you preorder they bring your supplies to the show, if they will
be there, so you don't have to pay shipping, which depending on what you are
buying can really be a savings.

OrchidMix seems to be the general use fertilizer of choice here. It was
developed at the University of Michigan, especially for orchids. You (and
everyone for that matter) can read about it's ingredients at the above
link. I would be interested to hear the assessment of the list members of
this formula.

Barbara

Looks right to me Peter − I did say that I thought the colour had changed in

its price is 49.99 it comes with a floating bouy so you can have it in a
dustbin if you like and fit it on a timer,if you dont use flotation put in a
container to cover device to abou2 inches (i think)it does say optimum water
level, when water runs out it switches itself off,the fog lasts as long as the
water,to fill grn hse you must have fan to circulate the fog humidity goes up
to 98% you cant see in front of you,i use it in with Draculas and Masd,im
rigging up timers to come on every hr for 10-15 mins ,still experimenting,but
wouldnt be without,i put ice in container to cool the air and sometimes liquid
slug clear ,and also pinch of fertiliser (soluble) well worth it Ron

Dear Dennis,

I can't possibly enter into a discussion as to the quality of culture in
other collections.

I do know that whenever there is any discussion about orchid culture, and as
soon as some-one says − such and such is good, or bad or essential, or
whatever − someone will put their hand up and contradict . To continue the
discussion, with that person,, is pointless − they have dug a hole for the
speaker , and whilst the speaker may find a reason why that person can
succeed against the odds, if they start asking questions, they may never get
to the right reason ( * see footnote) − in which case they are digging the
hole deeper. When in a hole ( whoever dug it) stop digging.

I will content myself with repeating −

Some UK orchid growers , who are aware how good these products are in the
garden, use them on their orchids, and because they grow and flower say "
there you are then, urea is perfectly OK for orchids" . What we don't know
is how much better they would do with another Nitrogen source !

And

about urea , . needing soil bacteria to make the nitrogen available is in
total agreement with general opinion among orchid growers. And I'll add -
all around the world , wherever there are soil scientists or scientific
growers, even if there are exceptions who think it does not apply.

And I won't say another word on the subject.

Geoff

Ps.

( in 15 years or more as a National Collection holder, no-one from NCCPG has
ever been in the slightest interested in my standard of culture ; and when I
was asked for " a piece for the Journal" and I offered one on culture, they
thought it not of sufficient interest to be worth publishing .)

* footnote, I once chaired a brains trust when a speaker from the floor got
into an argument with the panel, and claimed they succeeded with orchids by
never watering them.. After the meeting, someone else told me he was telling
the truth − his gardener did it...

Geoff, What about Calcium nitrate( The nitrogen being in the anionic form).
Sure I have read in these pages and others that Urea is not the best form of nitrogen for orchids, although I have seen these macro sacks of urea at some farms. I suppose you could call it a natural organic form of nitrogen.
I'm not saying you should pee on your orchids though!!

Geoff, I still have this radio temperature device to send to you, but have lost your address.
Could you send it privately to

The late David Sander used to say that he had seen human urine used
successfully as a fertiliser on Vandas grown in Hawaii ( I think it was
Hawaii) − that was a long time ago !

But the semi-terete and wholly terete Vandas ( some of which − maybe all of
which − are now in some other genus − but you know what I mean when I say
Miss Joaquin types.) were/are often grown in soil !

See the beds of the at Singapore Botanic Gardens. One of the gardeners told
me that the problem with them is that they get too tall and leggy , so they
prune them by cutting off the top half, and if they want another bed of
them, they just stick those top halves ( "top cuttings" ) in the ground. We
didn't discuss peeing on them.

As to Calcium nitrate, my electro-chemistry has oxidised a bit (joke) but it
is generally agreed to be the best form of Nitrogen − let me qualify that -
for epiphytic orchids being grown in inorganic composts or in organic
composts where ordinary soil bacteria cannot be expected to be present. Of
course, any trace of leaf-mould, or sand or gravel, or loam or ( especially)
peat , and soil bacteria may well be present, and can work with urea. Maybe
that's the answer ?

Just a note of caution − what sort of heating have you got?

I find with electric fan heaters that if the humidity gets too high the
fuses trip because obviously the fog gets into everything, not just the
leaves. I run my hydrofogger at just over 60 which seems to suit both the
orchids and the fans, heaters, etc.

My wife is a member of The Hampshire Guild of Spinners, Weavers & Dyers. I'm the one with chemistry degree, so I do the dying, which is fun but very messy at times. We only use natural not Aniline dyes. Some of the older formulations have urine as one of the ingredients and they say that small boy's urine works the best!!

Geoff, Found your address and will send max/min radio temperature alarm to you tomorrow. My wife will have to post it at The University of Surrey, where she works, as they have closed the post office at Four Marks, after some 100+ years.

Ron i have it on the bench at plant level for convenience
but it doesnt matter ,if you have it high with no fan it will just fall
under neath
also hard to fill ,on the floor it will still fill every nook and cranny
with fan another thing it warms the water if you want cool growing i put blocks
of ice in with it but it doesnt get too warm depends what you are growing?if
you order online today you can have it in the morning, it comes with 10mts of
cable
so the low voltage part is all thats in grn hse,I personaly use old washing
up bowl(she is still wondering where its gone)

Hi Peter,

It's no wonder that people like Bulbos when we see that photo of yours, they have so much going for them.

And now on to Red Spider Mite.

I once knew a chap who housed the National Collection of Red Spider Mite.

His wooden greenhouse was single glazed, and not a bit of shading on it whatsoever.

He grew his Cymbidiums in it !!!!!!!!!!

The benching stood on brick plinths, the floor was concrete.

He invited me round to look at his Cymbids..........and when he opened the door I was blown backwards with the heat.

As we should all know, keep your greenhouse damp/humid and you won't see the little devils.

Rocky.

Hello Geoff − belated reply, been away for a while. Trouble with using Jaybirds is I grow only in the house, so cant have soggy curtains! I thought Paul Johnsons post interesting though. I put several dendrobiums outside in July and they were very very wet for days at a time. I havent seen RSM on any and usually can with D. nobile. Anyway, seems Rocky has a sense of humour, I wonder who has the National Collection of Scale Insects?

I have been to lots of orchid shows in the UK and I went to the Miami Orchid
Show last February. I have to say that the Americans do them very well so
the Chicago show will no doubt be very good. However, the World Orchid
congress will be held in Miami at the end of January and , if you do not
have a special reason to go to Chicago, you might think of going to Miami,
which is very pleasant at the time of year,
