Producing a Keiki on a Cut Phal Spike?

[naturalgirl]

Good morning all,

I recently had some temperature troubles which led to bud blast on one of my phals. I ended up cutting the spike, and someone on another forum gave me the idea of putting the cut spike in a glass of water to see if it will make a keiki for me from the bit at the very end of the spike, which is still purplish green.

Has anyone here ever tried this? If so, any tips for me? I know this takes quite some time, and for now I'm enjoying the three small flowers I managed to salvage on the spike (they perked up a bit when I put them in water)... I'm willing to be patient

So, should I just keep it in plain water? Or should I maybe add a few drops of fertilizer?

Thanks everyone!
