    quite right, paul! wasnt even thinking about that! my plant forked a while back and has 2 primary vines of reasonable length/age that are currently growing their booties off, i could tape and plastic wrap one and leave the other as a control...oh so scientific, HA! and on of them i believe should be relatively easy to get to for this purpose...THANKS FOR THE SUGGESTION! it just helped form my plan of attack!! hope to have the experiment underway by weekends close!

    I didn't know ethylene induced flowering in orchids, I knew it worked only for Bromeliads. Ethylene as far as I know is a catabolic hormone responsible for abscission. Thats why I always remove any withering flowers, so that the ethylene doesn't cause the other flowers to die. But I can consult a friend, who I remember used some trick to bloom his huge shade full of vanilla, which wouldn't bloom for many years.

    OH, and as for the ethylene...ya, i dont know if it will work at all! quite honestly, it may even act as an inhibitor in which case i will be shooting myself in the foot big time!! (the fact that i cant find any info on this subject kinda leads me to believe i'm heading in the wrong direction...but what the hell! if it aint gunna flower this year anyway...whats the harm in having a little fun with banana peels?!)

    just in case anyone was interested in what happened with my experiment... now, the results might take months to develop.. but i think all i really managed to do was burn back some of the roots... but the section i bagged for about 2 weeks is actually growing faster and greener than the other branch of the vine... doubtful that has anything to do with my shenanigans tho ;-)

    Being a vegetarian, I used to have fruit skins in my compost bucket but then experienced the downside of early senescence of orchid flowers. Now I don't keep ripe fruit around during blooms. But your concept is certainly worthy. My hypothesis (educated guess?) would be that a fairly short exposure might be sufficient. Since the ethylene is acting as a hormone, even small concentrations might also be enough. I wouldn't even bag the plant but just keep the ethylene source close-by. This seems to work fine with broms.

    Denis aka bumpman thanks for literally bumping up this topic. I had contacted my friend Mr. Ashutosh Sathe, who has a trick to bloom his Vanilla and I would like to share that over here. The thing important to start with is that the plant must be an adult plant with suffieicent exposure to light, humidity etc. He had been growing his plant for many years, the creeper was long more than 8 to 10 ft a piece from the base till the tip and many such creepers were all over the place, yet they did not bloom. He got a tip from a vanilla farmer in India that the Vanilla won't bloom unless he used the coiling technique. It is a very simple mechanical technique. The creeper was coiled around a bamboo pole, each coil being roughly 1-2 ft in diameter, so instead of allowing the plants to grow straight he coiled them around the poles horizontally as suggested and surprise surprise, his vanilla bloomed the very next season.

    How interesting, Amey! The vanilla vines in our Atlanta Orchid Conservatory are coiled around the various structural posts throughout the space, as well as along the pipes and trellises above, etc. And they bloom vigorously and freely.
