    Talking Vanda Exotic Purple - Be Happy, Be A Vanda :-D

    Hello,

    The title of this thread just came to mind..I am determined to make all my Vandas happy.

    After the shock of discovering the state of my 'Vanda Exotic Purple, yesterday, (which is now in the intensive care unit, :P); the thought that my other Vandas could go the same way has entered the back of my mind.

    I turned my attention to my otherwise healthy looking dark spotty purple Vanda. Now there is an issue with the name for this one. I originally thought it was 'Sangsai Queen.' I recently found its' old label in a drawer and it is marked as 'Bangsai Queen.' However, it looks nothing like Bangsai Queen when in flower. After doing a few hours of online research, the closest visible match in terms of flower shape, structure and colour would be 'Vanda Robert's Delight Purple Blue.' I will therefore refer to this orchid as 'Vanda Robert's Delight Purple Blue?' from now on, the question mark indicating that I am not 100% sure.
    This is what the flower looks like:

    It has been a reasonably good growing season for this Vanda. It has produced new leaves, and a Keiki. However, what rang alarm bells with me is that I have heard that keiki production can indicate stress. I therefore decided to take it out of its pot (plastic pot with course bark and polystyrene).
    It looked like this:

    The roots are ok. Fortunately it has bigger, fleshier roots than Vanda Exotic Purple. However, there were early signs of rot. I cut these off, and washed the roots in tepid water. I cleaned out the plastic pot, and drilled holes all around the circumference (in the middle). I put fresh polystyrene and course grade bark back into the pot, which I loosely packed around the Vanda, leaving more of them exposed this time. I gave the plant a drink. I will wait for the roots to turn greyish before watering next time, but still maintaining my daily foliage spraying regime.

    I am tempted to do the same with one of my Vanda Blue Magic plants:

    This particular plant has great personal sentimental value to me. I have had it since I was 19 (I am now 23), and it was literally the second plant I acquired for my collection. About a year ago it was on the verge of death. I had it in a Vanda vase but I did not look after it properly (not on purpose), and it declined to literally just one root. It kept its leaves though. When I really started seriously collecting orchids I purchased another Vanda Blue Magic (my happiest Vanda), but I had a deep sense of guilt. I felt bad acquiring another Blue Magic when my current one was basically dying. I decided that I needed a method which would drastically increase the humidity around the roots; so I put it in a pot with polystyrene and course grade bark (as this was how some UK nurseries grow them for people to have in their homes), and I read up on Vanda care a bit more. I introduced a proper feeding, watering regime and put the Vandas in the lightest area with humidity trays. The little Blue Magic orchid remained the same for a few weeks, and then suddenly, as if by magic (pardon the pun), it sent down new roots really quickly. Its leaves improved too. It has taken a year, but it is now almost as healthy as my other Blue Magic Vanda. I can see nice big fat roots through the transparent pot; they have reached the bottom and starting to circle around the circumference.

    Apologies for rambling on, but what I have noticed is that the Blue Magic Vandas are quite a bit different from my two other Vandas. They are more tolerant of being pot grown, and infact are seeming to thrive in it! (Reference to one of them with a flower spike, I reckon a week and the buds should open, and the root growth of both plants ) The matter which worries me though, is the breakdown of the bark..A time will come when I will have to disturb my Blue Magic Vandas happy feet to change the bark. Really they need to be done quite soon.
    I have medium grade Orchiata bark, which I have repotted some of my other orchid species and hybrids into. However I think this is too fine for my Vandas. My current large grade ordinary bark breaks down too fast for my liking. I am thinking of perhaps getting some large grade Orchiata bark. The only option though is to get a great big sack of it, even though I only need it for my Vandas. Any thoughts?

    Also, has anyone else noticed that blue Vandas (ones with Vanda Coerulea in the parentage, atleast 50%), and those with fatter roots, are more resilient and tough then their finer rooted cousins? I find that quite interesting. Also, I have noticed that my Blue Magic Vandas are more tolerant of different temperatures and light changes.

    Regards,
    Kate.

    I do hope your vandas respond to your TLC. Yes the blooms resemble one of the forms of Robert's Delight. I'm not surprised that the blues do well in your cooler conditions as V coerulea comes from the cooler north of Thailand to other parts of the foothills of the Hiimalayas.

    Hello Kate, love the color on the vanda that is supposed to be sick, one question came to mind though, do you feel safe with it in a plastic pot? I think that the plastic encourages root rot, a suggestion; why not put it into a wire basket or even mount it on a nice piece of driftwood, that way you can really see the roots properly and it would be growing just as it would be in the natural, I have a vanda set in a wire basket in cocout fibre and some small stones and charcoal mixed, the roots are growing really profusely and the plant has produced three sets of flowers from December last year up until last month and still in bloom, depending on your temperature conditions you would know which is best, but happy growing to you and all success

    Might be worth adding some Hydroton/LECA to the mix , especially at the bottom of the pot.From what i have learned this will increase the lifespan of the mix , if you dunk the plant when watering the Hydroton/LECA will then get saturated & release the moisture over a few days but will not rot the roots.

    Hi Brenda,

    Thank you kindly for the advice. That is ideally what I would like to do, as it would be healthier for the Vandas, and would look better too! My problem is lack of humidity...I am thinking of trying to get hold of some terracotta pots with holes in, at least they would although the medium to 'breathe.'

    Hi Steve,

    Thank you very much for this tip. Also, out of interest, what medium do you use? I see that you live in the UK too. Yay! :-)

    Hi Yew,

    Thank you very kindly for your response.

    Bark mixes generally , S/H or Rockwool for phrags , started to add a little sphagnum to my phal mixes.Did grow a vanda Blue Magic in s/h but when i shut down grow room temperatures where to cool & it declined & died quickly.

    I think Steve has a good idea with the Hydroton/LECA , maybe even some charcoal, that's my 2 cents. good luck

    I agree. Some hydroton should help keep the roots from rotting in a plastic pot like that.

    cheers,
