Vanda

[lestrodamus]

I have a potted vanda that was purchased 2-3 years ago from RF. At $125 its the single most expensive orchid plant purchase we've made. OK, I'm cheap, but the mortage comes first.

The plant consists for three potted vandas around a tree fern pole, they've at least doubled in size since the purchase. Only one of the plants ever blooms. In fact I noticed about a week ago that two new spikes were developing on this one plant. One spike dried out before it was
3/8" long, the other is growing nicely.

Why would only one of the plants bloom? They obviously get the same fertiler, they're all in close to full sun.
Last year it bloomed in sept and again in dec/jan. Hoping for two blooms this year.

Thanks for the response:
The plant is in S. Florida from noon on it gets full sun. The only time S.FL is greeted with low humidity is now until sometime in March.
They are three separate plants in one clay pot. Media consists of Aliflor and some charcoal. The tree fern stake is just for stability, but some roots have grown thru it. BTW, the roots on all three are fabulous.
Each plant is at least 36" tall, but only one has ever bloomed. The flowers are not small. RF tells me that they are all the same plant and have been potted together since being seedlings.

I will post a picture on alt.binaries.pictures.orchids, I'll call it "vanda bloomer issue".
