Vanda
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. |

Vanda
Hi Barry,
You don't mention all the conditions. You say full sun - where? There's a big difference. How about humidity? Low humidity could cause the bloom stem to blast and keep the others from blooming. What medium are they in? Some vandas are totally intolerant of heavy medium and must be in a wooden basket with maybe some cork, charcoal chunks, or pumice to stabilize them. Most vandas appreciate being watered daily which means the drainage must be absolutlely perfect. A couple of possible suggestions: 1- The bloomer may be precosious. It may a species or hybrid that blooms younger than the others. Are the blooms smaller as in ascocendas? Some vandas just need to be larger in order to bloom. 2- It may be a species/hybrid that blooms in lower light than the others. are any of them terete (pencil-shaped leaves). Some flat leaved varieties will bloom in lower light than others. Terete-leaved varieties will be very difficult to bloom in northern areas or under lights.

Vanda
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". "V_coerulea" wrote in message ... Hi Barry, You don't mention all the conditions. You say full sun - where?
