Slowing down flowering....
 

I know, why would anyone WANT to do that, but....

I have a D. pulcherima that is currently flowering. It now has 4 flowers open, a fifth opening and several other buds in waiting. I want to display this plant at our show on 10/13-14 and want to retain the flowers as long as possible in as good of shape as I can.

Is there ANY way to slow down the cycle to accomplish this?

How long did it take the first four buds to open? D. pulcherrima usually carries around 25 flowers per inflorescence. Its flowers are generally long-lived, but they are not all open at once; norm is 10-15 open at once. (By the time the last bud is mature enough to open, the first flowers have senesced.)

I'd be reluctant to slow this plant's blooming down, but if you must, try reducing light and temperature a bit ...
Move the plant straight back from current light source to get it into lower light. Keep orientation the same so that new bloom open in the same direction as the first flowers.

Good luck at the show
