VANDAS & their cultivation
VANDA FAMILY & THEIR CULTIVATION* COLLECTION* Vanda, the original "sanskrit" name for orchids, grows in the regions ranging from India to Philippines and consists of about 60 species. The plant is an epiphyte and produces abundant flowers. Flowers grow laterally, upright from the base of two leaved shoots; leaves usually strap-shaped but can also take other forms. Often several flowers are produced by one plant. An orchid that is easy to cultivate and maintain Vandas certainly are a collector items. I have seen several of the species from the subcontinent still growing as epiphytes in big clumps in trees. Some of you must have heard about Arandas, Mokaras, Kagawaras, Renantheras, Ascocentrums, Rhynchostylis-- all belong to the Vandaceous Alliance. Not to forget the great Blue Vanda - Vanda coerulea....or the most commonly crossed Vanda sanderiana. Each genus has a typical trait and unusual features that make them distinct and prized. Most of these are monopodial in habit with their leaves terete or semi terete or some with broad leaves. They require a lot of sun and most of them are climbers with aerial roots appearing along the stem. Many strap leaved Vandas have an attractive scent that is strongest during the day, especially the AERIDES family which is so strong in their perfume it makes one dizzy. Most of the Vanda orchids have common names like Scorpion Orchids or Spider orchids as called by the growers. Some Vandas are cultivated in Beds and some in Wooden Baskets Hanging in mid-air in a greenhouse. The culture conditions are totally dependent on the type of plant habit - sunlight needs,
etc. They are heavy feeders and can with stand harsh environments. Most of the growers tend to dunk these orchids with Organic manure and other solutions. The major variants in the group are Terete Vandas from the Vanda Arachnis tribe, Arandas, Renanthera group such as Renantanda, Renanthopsis and Aranthera. Aerides have been bred in search of different flower form, shape and colour, as well as the Multi-generic hybrids The total number of multi-generic hybrids in the monopodial orchids is over 60. Many multi-generic s are not so tall and are less tolerant of full sun than those parent plants that are climbers. These orchids thrive well on High Humidity conditions and need watering at least once a day with the Compost kept moist all through. They need support or staking at times, and also good ventilation between the plants. Most of these Orchids have been grown and hybridized in the South East Asia for many many years. Most of Thailand, Malaysia, Singapore, Indonesia, India, Srilanka, Philippines are the places where one finds these varieties going grown in large areas. Some of the Varieties are still grown for the cutflower trade. The discussion that we are going to have, in general, will center around the different Hybrids of Vanda family and their growing conditions as well as the cultural Habits.... I have put up a web page showing some of these in Visuals. These were taken during some of My visits to the Growing Regions of Malaysia, Thailand and Singapore. Please do visit the Link page for more Information.
like Mokara (Arachnis X Ascocentrum X Vanda), Holttumara (Arachnis X Renanthera X Vanda ), Bokchoonara (Arachnis X Ascocentrum X Phalaenopsis X Vanda ), Kagawara (Ascocentrum X Renanthera X Vanda) are very commonly grown.

jagso (JAGS,ORCHIDSASIA,Bombay.)
Good Evening to all of you.... Welcome for the discussion about VANDAS.
I have put up some of the images for discussion in the Orchid
Asia web pages of mine. Here are all the photo pages related to the discussion tonight. The images have been loaded on to the directory starting with "Vanda Growing" and continuing with a detailed view in "Vanda
growing - 2" , and assorted hybrid pictures in pages"Vanda Growing - 3",
"Vanda Growing
-4" and "Vanda
Growing -5"
Most of the Vandas fall into the broad classification of Terete, Semi terete, Quarter terete, or strap leaved - based on their leaf structure.
JCY8S (John in Arcadia, CA)
They are not hard to grow here - except the terete or semi-terete types.
Ellen,Smithtown,NewYork
A little more difficult in New York.
onelaelia (Caracas)
What is the growing medium in the last photo, soil? sand?
jagso (JAGS[ORCHIDSASIA,Bombay.)
The medium in the last photo is basically sawdust, as you can see specifically in the photo from the page titled "Different Ways of Growing".
marilyninOttawa :
Which type of tree is the sawdust from?
jagso (JAGS,ORCHIDSASIA,Bombay.)
Basically the sawdust usually available here from saw mills that cut Teak into slabs and planks.
Richard in West Palm Beach
Why are teretes and semi-teretes harder for you John?
JCY8S (John in Arcadia, CA)
Richard, those are hard for me as I can't give them enough light. Outside I would have to water several times during the day in summer and then try to find room inside during the winter. NO room there. How about a Vanda tricolor var suavis? I think that I have an extra one. Also in bloom again now.
marilyninOttawa
Mokaras are some of my favorites. Any suggestions for the best of the latest cultivars coming available?
[There are a lot of Mokara crosses available.. Mokara Chark Kuan has been running steady for a long time.. The best Mokara crosses available today are Mokara. Walter Oumae, Mkra. Mak Chin On, Mkra. Khaw Phiak Suan, Mkra. Bibi, Mkra. Bangkok Gold.. to name a few...JAGS.]
hyphae
How large does the tricolor suavis have to be to bloom?
[At least one foot long, in vegetative growth with good roots hanging..JAGS]
JCY8S (John in Arcadia, CA)
Tricolor suavis has to be about 18'' tall to bloom for me but I really do not grow it that well.
onelaelia (Caracas)
Hyphae, my suavis blooms on growths of over 1 ft, subject to a temperature
drop.
JCY8S (John in Arcadia, CA)
Yes onelaelia - temperature does effect the blooming here.
charliem2
I have tricolor 'suavis' x Mimi Palmer...won't bloom till 2+ feet, but then continuous.
onelaelia (Caracas)
I grow suavis & luzonica outside, on a stump made up of treefern logs and they have branched freely over the years, am about to undo the mess and start again, although I now have stacks of growths.
jagso (JAGS[ORCHIDSASIA,Bombay.)
Most of the Vanda like tricolour or sanderiana are best grown hanging in wooden baskets where the roots are exposed to humid air.
JCY8S (John in Arcadia, CA)
I have one tricolor potted in a clay pot with wine corks. It does best after the roots get out of the pot.
hyphae
Guess I have a while, mine is just 6" tall, the leaves are each about a foot long.
Ellen,Smithtown,NewYork
Jags, I have trouble in the winter. They are as high in the greenhouse as I can get them for max warmth and light but sometimes the water stays in the axles of the leaves and I don't realize it till it is too late.
jagso (JAGS[ORCHIDSASIA,Bombay.)
Ellen, Vandas like more sun compared to all other species and in winter the only way is to keep them max. warmth as you had indicated.. But water you should be careful. A little less is Ok. If the water stays in the crown the leaves might get damaged or may also tend to get bacterial attack.
Ellen,Smithtown,NewYork
Is it true the blues are cooler growing?
charliem2
Ellen...in my area, no...have V. Rothschildiana blooming alongside semi teretes.
johngingarland
JAGS, what's the lowest temperature you may have during a year?
jagso (JAGS[ORCHIDSASIA,Bombay.)
Our lowest temperature here in Vanda belts could be around 22*C...
marilyninOttawa
22C is approximately 70F
onelaelia (Caracas):
We go much lower 61F, and they seem to like it.
BCPRESS (Bert in Miami)
The New Coerulea out of Thailand, 3Nx4N. Is it really Coerulea?
[I think they are self crosses to improve the flowering characteristics..JAGS]
jagso (JAGS[ORCHIDSASIA,Bombay.)
More information on the growing aspects of vanda is in the link page "Vanda Growing - 2" [Button]
marylois (TOPIC IN SESSION)
Oh, Jags! Magnificent! Ever get snake-bit in that jungle?!
[Oh, We meet them so very often.. They just don't bite but do give you a look - JAGS]
JCY8S (John in Arcadia, CA)
JAGS - what is the normal humidity?
jagso (JAGS[ORCHIDSASIA,Bombay.)
The normal Humidity is around 60-65% RH...and can go up to 85% Rh in the mornings or night.
johngingarland
JAGS, So your plants don't really go dormant, do they?
hyphae
What is the optimal time for repotting, my tricolor is now in bark in a plastic pot, and would like to get it into a basket
jagso (JAGS[ORCHIDSASIA,Bombay.)
There is nothing like optimal time for VANDAs. We do the potting for new plants all the time.. But once it is potted or planted it lives for years together on the same container..We only use wooden Baskets for VANDAS which like more ventilation. The Garden types which are planted in the ground are left in the ground itself with more staking to keep them growing higher.
JCY8S (John in Arcadia, CA)
Here in CA I would think that you would want to repot in the early spring as the new burst of root growth starts.
Richard in West Palm Beach
I think in Thailand and probably most of SE Asia, the Vandas are in constant growth and don't really ever go completely dormant. Here, I would leave all repotting or moving to larger baskets until a warm weather cycle begins and roots are in active growth.
JCY8S (John in Arcadia, CA)
You said that much better than I did, Richard but that is what I mean. LOL
Ellen,Smithtown,NewYork
Jag, I grow in wooden baskets with no media. Would it help to add moss or another media in the winter to help the plants when the heater is going full blast?
jagso (JAGS[ORCHIDSASIA,Bombay)
Hello Ellen. It is better to add some bits of Charcoal blocks. That is sufficient.
Richard in West Palm Beach
Charcoal is great for Vandas because it does not break down and Vandas do not like to have their roots disturbed. I only move them when the basket deteriorates and then only by placing the whole old basket and roots into a larger basket. I have friends, though, who just have the plants attached to a wire hanger -- no basket, no medium, and they grow and flower well for them.
Ellen,Smithtown,NewYork
How low can nighttime temp go?
[Mostly it is around 20-22*C .....JAGS]
marilyninOttawa
I was wondering about fertilizer application. What do you use, when do you apply it and does the rate or frequency of application vary with the season?
jagso (JAGS[ORCHIDSASIA,Bombay.)
Well Most of the growers here use a lot of Organic fertilizer like Gobar solution or fish emulsion which they dunk on the orchids several times. Some even use to feed them with Goat wastes also... Technically you can use a slow release fertilizer of the type like OSMACOTE or HiLEAF ones the general purpose being 20-20-20 or flowering with High P and High K like the 14 42 14 or the 16 4 31 available. Some growers in Thailand use a formulation known as GAVIOTA 63 and GAVIOTA 67.
marilyninOttawa
I used fish emulsion while living in the Caribbean. It worked wonders.
marylois (TOPIC IN SESSION)
Yes! ...just cannot stand odor of fish emulsion in the greenhouse...outside, it's not too bad.
jagso (JAGS [ORCHIDSASIA,Bombay.)
Hello Marylois.. they have now a highly refined fish emulsion solution .. I think it is YATES packed beautifully for use in Orchids available of the shelf. No smells. Some growers also use something like a seaweed extract...which also is commercially available now.
JCY8S (John in Arcadia, CA)
YATES?? Maybe I am famous! LOL
KB Barrett (Kathy in N Calif)
Jags, If water stands in the leaf axils and grows algae, will that inhibit flowering? There is no other infection, just algae growing in the standing water at the leaf axils... I'll usually try to clean it out with a jet of water.
JCY8S (John in Arcadia, CA)
Kathy - it has rotted flower spikes for me.
charliem2
Kathy...if you get crown rot, pull the top leaf, and flood with peroxide...kills the soft rot, and a new leaf will grow.
marylois (TOPIC IN SESSION)
In rainy climes you can put a half teaspoon of WP fungicide [e.g., Captan) in the top axil - it washes down stem into all axils as it rains - I've used it here when we go into those 3-6 week rains.
jagso (JAGS[ORCHIDSASIA,Bombay.)
If there is rotting in the crown usually it travels down so it is better to remove the bad foliage , cut off f the top portion and treat it with good fungicide or Bactericide. Usually after it is kept dry a new second growth
takes place.
foxtail2
jags what is the best way to control scaling?
[It is suggested to use Albolineum (white oil) with or without added insecticides as suitable dosage against scale insects.. Why don't you also try a deterrent..Neem oil..Azadhriztin.. as a preventive dosage...Jags]
Ellen,Smithtown,NewYork
Jag, because of limited space, when the vandas get too tall I remove the top with its roots and repot. Is there a particular time when it is best to do this?
[ No there is no specific time.. for this.. But ideally when Humidity is high as in monsoon season it might get established faster. Jags]
charliem2
Ellen...I topped several vandas this summer that were 6-8 feet; the bottoms have many keikis.. I keep the bottoms w/keikis, give the tops to local OS for sales, auctions...
Ellen,Smithtown,NewYork :
Charlie I get rid of the bottoms. I have too many plants for the greenhouse now. I don't need doubles of Vandas. My problem other than size is the bottoms look lousy, loss of leaves etc.
marylois (TOPIC IN SESSION)
Ed always says, give away the top, keep the bottom!
sparkysteve (TOPIC:VANDACEOUS ORCHIDS) (Boca Raton Florida)
Ellen you can top them, and in less then 3 years a new keiki should be in flower in the old basket.
KB Barrett (Kathy in N Calif)
Jags, a couple of weeks ago Ursula had a question about pruning roots on a Vanda, any advice?
[ We don't usually prune the roots. Incase it is cut sometimes the growing root tip is lost and the root stops growing.. I don't think it is better to prune roots...Jags]
Lanceps (Thamina from Manhattan Beach, Calif.)
I hope to grow some smaller Vandas and Ascocendas in a GH that will only be heated up to 55 degrees F. I live in Southern Calif., near the coast so high humidity.
Ellen,Smithtown,NewYork
Jags, are some Vanda hybrids more vigorous and temperature tolerate than others?
[Ya, Sure.. There are special Vanda crosses that you may try that can tolerate temperature fluctuations..Jags]
Ellen,Smithtown,NewYork
Jags, I'm in New York and their outdoor growing season is not very long, maybe three months.
jagso (JAGS[ORCHIDSASIA,Bombay.)
Hello ellen ..I think you need to find a good hot place with light levels that are good for the Vandas to grow well and bloom.. Usually the bottom leaves turn yellow and fall when it becomes old... But as you see in the photos.. the root growth has to be like flowing Hair.
Ellen,Smithtown,NewYork
That's what light and heat can do for you
jagso (JAGS[ORCHIDSASIA,Bombay.)
Also look up the picture
marylois (TOPIC IN SESSION)
That one really shows the roots, Jags!
Native Heart
WOW LOOK at those beautiful roots and healthy leaves!!!
Jane5536 (Huntington L.I. N.Y.)
I have had a vanda x with ascda for over 10 yrs--11/2 ft tall but never has bloomed-keep it in good light & in full sun in summer-- feed it but I'm stumped!!
[ May be you should try and change the culture.. and growing position..JAGS]
Ellen,Smithtown,NewYork
Jane, Clark only uses fish emulsion and look how his grows.
KB Barrett (Kathy in N Calif)
Jags, The roots don't get wrecked from the sawdust when it breaks down?
Acid?
jagso (JAGS[ORCHIDSASIA,Bombay.)
The roots at the bottom are only a few.. and they are very green and nice .. May be a little browned over the years.. but no damage.. You have to treat the sawdust before use .. May be wash and dry in sun before use.
KB Barrett (Kathy in N Calif)
Ah HA! I knew there had to be a technique to it!
johngingarland
Nice Roots! JAGS
Ellen,Smithtown,NewYork
Jag what do you put in your baskets, also sawdust?
[Just nothing.. Only a few Charcoal pieces.. JAGS]
marylois (TOPIC IN SESSION
Oh my!!! Hair, indeed. I was led to believe vanda roots in Thailand were skinny -Those look plenty plump to me!
KB Barrett (Kathy in N Calif)
Do they use a chain saw to cut them into individual plants?? *G*
Native Heart (Jane in Fort Laud )
I am impressed
sparkysteve (TOPIC:VANDACEOUS ORCHIDS) (Boca Raton Florida)
I once heard that a plant that would take 5 years to bloom here in south Florida---would do it in 3 years in Thailand!
KB Barrett (Kathy in N Calif)
Why Sparky? The sun is the same...
marylois (TOPIC IN SESSION)
...lots of humidity...yet not so hot so long, so often...
sparkysteve (TOPIC:VANDACEOUS ORCHIDS) (Boca Raton Florida)):. .
Kathy---that reply was from Bob Fuchs--we still have winter here and it slows down their growth--rfOrchids has property over there
KB Barrett (Kathy in N Calif)
Ah so!
marylois (TOPIC IN SESSION)
Did you say what trees the sawdust is from? If so, I missed it. Sure wouldn't be soft southern pine.
KB Barrett (Kathy in N Calif)
He said Teak Lois
marylois (TOPIC IN SESSION)
No wonder - doubt if even cedar would hold up in our hot, humid conditions. Thank you, Jags - how very wonderful for you!
hyphae
What are the plants in the plantations used for? Are they cut into individual plants, used for cut flowers??...
[Mostly Mokaras, Arandas, Kagawaras are used as cut flowers .. Other vandas are only for pot plant display and landscaping...Jags]
johngingarland
JAGS, - Do you have any automatic misters, or would that be a luxury that would be too expensive?
jagso (JAGS[ORCHIDSASIA,Bombay.)
Only for Arandas and kagawaras we use misters. The orchids in the open sometimes have also sprinklers spread in rows to keep the humidity high...
charliem2
marylois...I have V. rothschildiana hanging on a wire..no basket...no pot...it's about 5 feet tall, in bloom...
KB Barrett (Kathy in N Calif)
Where are these plants exported? Japan? USA?
[Yes, some are.. The open market picks up the rest..JAGS]
onelaelia (Caracas):
So what could we use instead of TEAK wood chips???
[May be they have a wood chip ORCHID mixture available.. Otherwise try Hard Charcoal. JAGS]
KB Barrett (Kathy in N Calif)
Jags, so its humidity, constant warm temps, fish emulsion, and teak sawdust and we'll be able to grow like you! Hehe! Lovely photos!!
Ellen,Smithtown,NewYork
Kathy sometimes you are lucky and you find a plant that blooms 3 or 4 times a year.
graphicgreg (Georges not Welcome)
Sounds like tough requirements for you to fill Kathy, don't forget the bright light.
johngingarland
Lois, I don't know about your bodacious slugs, but any plant here close to the ground would get eaten.
marylois (TOPIC IN SESSION)
Amen, John.
Lanceps (Thamina from Manhattan Beach, Calif.)
I saw Vandas in Singapore, my favorites were huge.
jagso (JAGS[ORCHIDSASIA,Bombay.)
Dear Lanceps did you see anything like this? picture . You can see the whole page as loaded in "Vanda
Growing - 3" and "Vanda
Growing - 4"
Lanceps (Thamina from Manhattan Beach, Calif.)
I don't think so. It was January. Most of the plants were Not award quality. I guess they aren't breeding for hobbyists. Lots of color,lots of flowers. Saw Mokara Bota Gold. WE were between planes, going to India. We only saw the Singapore Botanic Gardens
jagso (JAGS[ORCHIDSASIA,Bombay.)
One of the finest displays of Vandas in a garden setting is at MANADAI Orchid Gardens in Singapore where one finds wonderful Vandas used beautifully like in this picture
or picture which
is a same flower like the VANDA Miss Joaquim..
KB Barrett (Kathy in N Calif):
Jags, those are wonderful! What a neat way to use them in a garden!
jagso (JAGS[ORCHIDSASIA,Bombay.)
Dear John,What you should do is prepare the ground.. Make a layer of gravel like an artificial bed of sorts, put brick pieces over them and then charcoal and finally saw dust.
Ellen,Smithtown,NewYork
Are Arandas easier to grow in cooler climates?
[May be you should try???.. Jags]
graphicgreg (Georges not Welcome)
jags, that is how we grow terete Vandas here in South Florida also - in wire cages in full sun in the yard.
marylois (TOPIC IN SESSION)
Puts rosebeds to shame, doesn't it?
Ellen,Smithtown,NewYork
They are spectacular.
jagso (JAGS[ORCHIDSASIA,Bombay
Dear Lanceps did you see the Miss Joaquim in display at the Singapore Botanic Gardens where they have landscaped with all those lovely Vandas.
graphicgreg (Georges not Welcome)
Recently I have seen some semi-terete Vandas that are as desirable, or more desirable, than Mokara, Aranda, etc. They may also be grown as landscape plants but have huge flat round flowers the size of saucers. Ones I have seen are mostly yellows and pinks
jagso (JAGS[ORCHIDSASIA,Bombay.
Here is the photo link for the same. Singapore
National Botanic Gardens.
Lanceps (Thamina from Manhattan Beach, Calif.):.
I've always loved Vanda Miss Joaquim. I first saw it being passed out in corsages at a supermarket grand opening in Seattle, over 40 years ago. Seeing it hooked me on lavender orchids for life. I grow mostly cattleyas now.
jagso (JAGS[ORCHIDSASIA,Bombay.)
Also look at the VANDA PROLIFIC.
Lanceps (Thamina from Manhattan Beach, Calif.)
In Singapore they were 7 feet tall. What size do they bloom at?
KB Barrett (Kathy in N Calif)
Greg, do you make the beds the same way as Jags describes?
jagso (JAGS[ORCHIDSASIA,Bombay.)
Usually Miss Joaquim after 2-3 feet growth..
marylois (TOPIC IN SESSION)
The opening in the center of the white bed???? Is the opening in the bigger beds for cleaning out center and preventing rot?
KB Barrett (Kathy in N Calif)
Jags, in one of the other photos you describe a flower as quarter-semi terete, what does that mean?
jagso (JAGS[ORCHIDSASIA,Bombay.)
Dear Barrett they identify the plant by Semi terete and Quarter terete by the way the leaf is in a VANDA.. the fully terete plants have a cylindrical leaf but the semi and quarter have leaves that are long narrow, and channeled. See the pics.. picture
graphicgreg (Georges not Welcome)
No Kathy, we just stick the plants in the cage - usually they have whatever pot they were established in still attached - no media added - just water
KB Barrett (Kathy in N Calif)
Greg, And the cages are hung up or on the ground like these are or what?
jagso (JAGS[ORCHIDSASIA,Bombay.)
Marylois it only a design feature.. of the display.. what they do is make a ring out of Bamboo or wood and put 2 sets of plants one behind the other and when it flowers the foliage is dense as well as the design looks good..the center cut out is ther for one to go and clean the plants and maintain the ventilation..
KB Barrett (Kathy in N Calif)
Must be fun to be a gardener there, everything grows! Well, I'll just have to console myself with California's ability to grow cymbidiums in full sun in the ground.
graphicgreg (Georges not Welcome)
RF Orchids uses Miss Joachim as a hedge around his grounds - very beautiful effect
sparkysteve (TOPIC:VANDACEOUS ORCHIDS) (Boca Raton Florida))
I have some Miss Joachim in a wire basket ton my lawn with no medium--I shift it when I have to mow the lawn.
graphicgreg (Georges not Welcome)
They're on the ground Kathy - like tomato cages - we usually use chicken wire and a bamboo stake for support.
KB Barrett (Kathy in N Calif)
Gotcha Greg.
Lanceps (Thamna from Manhattan Beach, Calif.)
I have a nice little red,V. Judy Miyamoto x Ascda Peggy Foo, growing in a 5" pot, with bark 1/3 deep and roots circling above the bark. Is it okay in there?
Ellen,Smithtown,NewYork
Marilyn, you're in cold country. How do you grow your vandas?
KB Barrett (Kathy in N Calif)
Thanks Jags for the explanation! Makes more sense now. Whereas a 'strap leaf' vanda the leaf lays flat open - or nearly so?
Evlyn
Gorgeous--gonna go pack my suitcase and go to Singapore.
Ellen,Smithtown,NewYork
Jags, are there plants that just won't bloom?
jagso (JAGS[ORCHIDSASIA,Bombay.)
Dear Lanceps... it is Ok and fine. Let it get exposed as much. The roots love to get displayed well.
jagso (JAGS[ORCHIDSASIA,Bombay.)
Dear Ellen Almost all the Vandas are very very easy to bloom. Nothing Great. Just the right Light. Right humidity and little food round the clock.
sparkysteve (TOPIC:VANDACEOUS ORCHIDS) (Boca Raton Florida))
jags, do you ever have the problem with too much fertilizer? I mean causing more vegetative growth and no flowering?
jagso (JAGS[ORCHIDSASIA,Bombay.)
Yes Sparky. some times it happens. Then you have to reduce the N and adjust and wait for 2-3 months for change to take place...
KB Barrett (Kathy in N Calif)
Ooh, good tip Jags!
virtualmeridian :
I have an Ascda. Duang Tarn. Does anyone know if it will do well outdoors? It's in the low 60's (nights) and it creeps up to about the mid 70's during the day.
jagso (JAGS[ORCHIDSASIA,Bombay.)
Now only for the last photo for the session of a THAI sunday market shop selling VANDAS. [picture]
graphicgreg (Georges not Welcome)
I would think that the 'too much fertilizer' issue would be more likely with fish emulsion which is high nitrogen rather than a balanced fertilizer. Many growers use a 'blossom booster' high phosphorous fertilizer every third or fourth feeding
sparkysteve (TOPIC:VANDACEOUS ORCHIDS) (Boca Raton Florida)
virtualmeridian, I would say it'll grow OK.
KB Barrett (Kathy in N Calif)
Virtual, they grow well here in N Calif., but we need to keep them in a greenhouse, not outside.
jagso (JAGS[ORCHIDSASIA,Bombay.)
Usually the overdosing happens only with the commercial fertilizers and not with the Organics...Thanks Greg.
onelaelia (Caracas)
Virtualmeridian, it will grow OK, but a higher daytime temp into the 80's would be better.
virtualmeridian
Would I have better luck keeping them indoors during the day? (apartment, not a greenhouse)
BTague (BarbaraIn No. Calif.)
I'm just green with envies, either I move to Thai or give up Vandas.
KB Barrett (Kathy in N Calif)
virtual, where do you live again? The duang Tarn is one of BTague's favorite orchids
graphicgreg (Georges not Welcome)
You could always move to Florida Barbara !
virtualmeridian
I live in the Los Angeles area.
BTague (BarbaraIn No. Calif.)
Yes, I have about 3 Doug Tarn, they are doing fine,
jagso (JAGS[ORCHIDSASIA,Bombay.)
Thanks to all of you for your time in the wonderful Vanda Chat.. if you need any more lovely visuals about any of these vandas or other families please do write to my email and I will get it for you... I have documented and photographed many from the Far east belts. Thank you all for the good
