Ascda. Kultana Miami White.......My Nemesis!
 

Anyone else have this plant?

I am up to spike number seven with the 1st 6 always blasting. I'm kind of hoping that it's just too young and too eager, rather than me being at fault!! :)

Spike number 6 got to be twice as long as the preceding 5 before it blasted, hopefully spike number 7 will make it through. It is a prolific spiker.

The plant is otherwise healthy and happy but stands about 15-20cm in height.

I think I got it last October or thereabouts.

How strange! Can you tell us about your growing environment?

From your location I would presume that temperature conditions are not the issue. What about light & water?

Do you have other Vandaceous plants that are blooming normally?

Watered every morning without fail. Currently in a temporary position until its new abode is completed but still in a position that gets quality light and air movement. Its on an east facing location lt gets full midday protection but light is still bright and indirect. Gets very late afternoon sun.. Hanging next to other vandas which are spiking and blooming as they should be. I may try a weekly fertiliser bath and see how that goes in case it's not getting adequate feeds fertilising by hand.

You may have something regarding the fertilizer. Vanda and vanda types tend to be heavy feeders. I personally will let my large true vandas soak in weakly fertilized water for many hours once a week and they get misted heavily daily as well. I stopped doing that for a while and they declined. I'd try the soaking.

If your other Vandaceous plants bloom normally, I would tend towards thinking, that this one plant is super sensitive to something that the others have no problem with.

In Paphs there is one plant (St Albans, a classic red), that is known to blast buds repeatedly. I have not encountered this in the Vandaceous group though.

I gave it the soak yesterday and instead of standard hand fertilising I'll continue soaking each weekend to see what difference if any occurs.

Well........spike number 7 has also blasted......The parents are kultana x adisak if anyone is familiar with them. Other vandas immediately either side of this one are spiking and blooming no worries so I will be persistent and hopefully sometime in the near future you'll see a successful bloom!!!!!

I need you to look for a few things here. Look at the crown of your plant where the new emerging leaf tissue is; tell me if you see a thin pale/white where the leaf hasn't developed chlorophyll as yet. Measure from where new leaf emerges to where the pale/white part stops. Also look at your roots and tell me if they have damage in the appearance of a ring near the root tips, almost looks as if the ring was sand blasted.
Lastly are the roots long and thin or really thick?
After you answer these I can further help.
:)

Some roots are rather scrappy but i'm still managing to get good roots as well........Okay I guess photo's are better than words....

A better photo would be from the side or head on i guess you would say not from above, so i can see the full picture and look for the new tissue growth at the crown to see if you are over or under-fertilizing. But looking at that one root of the few, it is very possible that you have a mild thrips problem.
Send the head-on pic though so i can get a better look at the new tissue growth at the crown.

Extra's as requested!!

Ok, I would suggest you spray for thrips, and there seems to be almost no new leaf growth and if so very slow by the looks of things. Suggests that you have an insufficient feeding regimen. A tbsp of epsom salt to a gallon of water once a month and fertilize more regularly. Every other day to start. Do several passes with the water or fertilizer to ensure full saturation of the roots. (No visible white/grey parts on the roots)
Your light seems to be great based on colour, so I would just suggest that from leaf tip to alternate leaf tip the plant is hung east to west so leaf tips on one side face east and the other side faces west. That is ensuring maximum light exposure for the plant.
Adding some calcium can't hurt either once a month. :)

Done deal! I'll let you know how it comes along.

Keep us updated...I'm sure it will come around. Remember you ideally want pencil thick roots and that usually comes with proper watering/feeding regimen.

Got another spike....fingers crossed

Well well well.......I finally managed to get this thing to flower, after 2 years worth of continual bud-blast.

Well okay, only 1 in bloom thus far with a second possibly 3rd flower on the way.

I went back and counted all the failed spikes, I got to 18 so yes, i'm pretty happy at the moment.

Beautiful!

Congratulations! Fantastic looking white BTW. I hope it settles down for you now and keeps blooming and not blasting.

Perhaps there are thrips? One of my friends had similar problem with vandas and now sprays developing spikes with Bayer 3 in 1. Solved her problem.
