no emergency here, just thought that i'd share a bit of recently acquired knowledge with anyone who's interested.
a while back, someone had posted that ordinary food dye could be injected into the flower stalks of a phalaenopsis to dye the flowers. I just tried this on my plant and it works!
It will take an awful lot of dye to get full colour saturation, and the stalk has track marks, but so far no flowers have fallen off, and no leaves or roots have died.
just thought you all might like to know that this doesn't appear to be harmful to the plant, this is it's 2nd week of having dye in its system.
